Thinking of Buying Winter Tires?
Don't forget to have a look at the APA's Winter Tire Reviews.

WINTER TIRE REVIEWS

For this year's APA winter tire reviews, we surveyed tire experts and tire dealers for their ratings of winter tires. This hybrid system offered several benefits, including the opportunity to rate a larger selection that we could normally evaluate in a conventional tire test. The APA places a higher  priority on  performance on uncleared roads over handling on dry payment, which accounts for differences between the APA's recommendations and published reports from some other sources. The tires listed here include most of the highly rated models on the market.

If you are planning to purchase winter tires, you may want to act soon, as several tire makers are offering rebates for the purchase of four winter tires that expire in December. These are either instant rebates deducted from the invoice by the retailer, which is preferable, or mail-in rebates, or a prepaid gift card. This table compiled by the APA provides the rebate programs offered for the major tire brands and deadlines for making a purchase. Customers applying for a mail-in rebate usually have about a month after the deadline to send in their coupon.

In addition to the rebates in the table mentioned above, participating APA Tire Retailers in Greater Toronto are offering APA Members a $30 after-tax rebate on the purchase and installation of a set of four winter tires. Non-APA Members are also eligible for a $15 discount at participating retailers.

Winter vs. All-season

The APA recommends winter tires because of their effectiveness on snow and ice. It’s unlikely that your all-season tires are adequate for winter driving in most parts of Canada, or in the U.S. snow belt. All-season tires provide modest traction on snow and ice when they are new, with grip diminishing as the tire tread wears down. The rubber compound of an all-season tire hardens as the temperature drops, providing poorer grip, even on dry surfaces. The compound of a winter tire is more pliable and retains its grip in cold temperatures.

Recently, a new class of FOUR season tire has appeared. These tires from Nokian, Yokohama and Hankook, to name three brands, carry the mountain and snowflake logo, but their manufacturers also recommend them for summer use. They are marketed as All-Weather tires. From what the APA has seen, these tires use a hybrid tread that manages to meet the winter tire traction requirement in snow, combined with the harder compound more typical of a conventional all-season tire. The compromise? Ice traction is not covered by the snow tire standard, an unfortunate ommission that should have been corrected. On ice, the hard rubber compund of a four season tire will not equal a dedicated winter tire. If your lessor will accept them, these tires can make sense in the last year of your lease if both your winter and all-season tires are worn out. The only tire in this class APA has any experience with is the Nokian Hakkapeliitta WRG2. It performed very acceptably in a winter test, outperforming some dedicated winter tires; we have limited reports from consumers who said it's traction was fine over the first winter. The WRG2 is expensive.

All-Weather tires are being promoted fairly heavily by some retailers in Pacific Coast markets like Vancouver, where ice and wet weather predominate, but roads are relatively snow-free. The tires are being recommended as equivalent to winter tires, without the hassle of semi-annual changeovers. At this time, the APA does not have enough experience in the West Coast driving environment to make a recommendation.

Four, not Two

Canadian consumers and retailers have known for many years that winter tires should be installed on all wheels. The APA occasionally receives inquiries from U.S. drivers regarding the possibity of installing two winter tires on the driving wheels, usually but not always, on the rear wheels of  a rear-drive vehicle. Here's why four winter tires are safer:

  • it optimizes performance of  the ABS braking and electronic stability systems
  • steering is important too; with winter tires on the rear driving wheels only, the steering can "wash out"

Installing just two winter  tires on the driving wheels of a front-wheel-drive vehicle is hazardous. The vehicle will appear to handle with confidence, providing all the right feedback from the driving wheels and steering until the instant the lightly-loaded rear loses traction. At highway speeds, this is can  involve a rapid and vicious loss of control, with the rear of the vehicle coming around partially, and the car going off the road tail-first.

How to measure tread depth

A new winter tire is delivered with between 10/32 and 13/32 tread depth. The wear bars moulded into the voids in the tire tread indicate the absolute wear limit of 2/32 of an inch tread depth. That's not considered safe for winter conditions. At the start of winter, experts recommend a minimum of  5-6/32 of an inch. Before installing your winter tires for another season, you can take a few minutes to measure the remaining treadlife by using a Canadian quarter with a caribou on it. Place the quarter, muzzle first, into the gap between the tire treads. If the muzzle is entirely buried, the tread measures at least 6/32nds of an inch, and is safe enough for  another 10,000 kilometers. If the caribou's muzzle is entirely visible, or the edge of the coin ahead of the muzzle is visible when inserted between the treads, the tire is likely getting close to its legal minimum tread depth of 2/32nds of an inch, and should be replaced. An expert can confirm the reading  for you using a tread depth gauge, or you can purchase one yourself; they're not expensive.  

Buying an extra set of wheels for winter

Tire and wheel sizes have reached absurd proportions on new vehicles, and buying a set of smaller, ideally steel, wheels for winter is a good idea. The initial $200 to $300 outlay can be recovered over a two or three year period by eliminating the cost of seasonally mounting and removing summer and winter tires from a single set of rims. This can save up to $50 each time you swap tires. In addition, steel wheels are more resistant to impacts, and better suited to severe winter driving conditions than more fragile alloy wheels. With very large wheel sizes, your winter options may be limited to a second set of alloys.

Buying smaller diameter wheels for winter allows smaller-inside-diameter, cheaper tires to be fitted. If you do opt for a smaller diameter wheel and tire, it is necessary to maintain the same total diameter of the original equipment wheel and tire combination. Your retailer has tire guides that indicate what the appropriate substitute sizes are. For example, on a Honda Civic LX equipped from the factory with 16 inch wheels shod with 205/55R16 tires, it is possible to install 195/65R15 tires on 15 inch wheels. Savings of $80 to $300 per set of four are possible by downsizing the wheel and tire combination, depending on the vehicle.

Swapping wheels is more complicated if your vehicle is equipped with a tire pressure monitoriing system (TPMS) of the type that uses sensors mounted on each wheel (more info on this below). In that case, you may be facing the purchase of a second set of sensors and alloy wheels in a smaller size for winter. Many consumers will simply stick with the original wheels and oversized winter tires with a change-over every spring and fall.

Speed ratings 

Speed ratings are indicated by a letter that establishes the maximum sustained speed capability of a tire when properly loaded and inflated. As with tire and wheel sizes, speed ratings for many original-equipment tires are wildly exaggerated for North American driving. Fast-wearing and hard-riding all-season and summer V-rated tires for sustained speeds up to 240 km/h are no longer uncommon on new cars. However, the winter tires that offer the best performance in bad conditions are seldom rated higher than T.

Here is a table giving the maximum sustained speeds for tires. In North America you are unlikely to ever reach the maximum rated speed of  any passenger vehicle tire, but the speed rating is also an approximate indicator of the tire's handling ability. A winter tire rated H or higher is likely more responsive when road conditions are good, but has a tread design that will not bite as well in deep snow. The best snow tires for really bad weather are Q, R, S, or sometimes T-rated. High powered rear-wheel-drive or all-wheel-drive vehicles (Mercedes-Benz, Audi, BMW) often feel mushy on tires with low speed ratings -- for those vehicles, moving down from their V or W-rated summer tires to an H-rated winter tire can be a good compromise.

Temperature

The rubber in all-season tires can begin to lose its elasticity in temperatures as warm as 7° C. The softer rubber compounds used in the construction of dedicated winter tires maintain their pliability, and therefore their grip, in temperatures going down to about -30° C.

Nitrogen

Inflating a tire with nitrogen helps maintain a more conistant tire pressure because it escapes the tire more slowly than normal air (which is composed 3/4 of nitrogen), and is less affected by temperature variations. For vehicles with Tire Pressure Monitoring Systems (TPMS), filling the tires with nitrogen may reduce the incidence of false alerts during rapid changes in temperature.

It costs up to $5.00 per tire to fill it with nitrogen.  To fully receive the benefits of nitrogen, the tire will have to be purged of air a couple of times before filling with nitrogen. While more stable than air, nitrogen will still leak out eventually. If a tire is low, filling it with air from a conventional compressor will negate the benefits of nitrogen. APA’s recommendation for most people: skip the nitrogen and buy a tire gauge instead and use it.

Coping with tire pressure monitoring systems (TPMS)

Increasing numbers of new vehicles are equipped with tire pressure monitoring systems (TPMS). On many systems (fortunately, not all), wheel-mounted programmable sensors transmit a signal to notify the driver when the pressure in one or more tires falls below a pre-determined threshold. Tire pressure monitors can add expense and complication to winter tire installation, especially if you have separate wheels for your winter rubber. For the TPMS to function properly, the winter wheels will need to be equipped with tire pressure sensors, which, depending on the make of vehicle, can cost anywhere from $35 to $75 per sensor. Switching over the sensors from one set of wheels to the other is discouraged to prevent sensor damage.

In many cases it is necessary to reprogram wheel-sensor-type TPMS systems during seasonal tire swaps. This can seldom be done without a special tool, and some dealers overcharge twice a year for this simple computer initialization. Independent shops now have access to programming tools to link up the vehicle with the wheel sensors; this was not the case when the APA first reviewed these systems in 2008. The more flexible TPMS systems allow the vehicle to recognize two sets of sensors without subsequent reprogramming. The least intrusive  systems, like those on the majority of  European luxury vehicles, dispense with wheel-mounted sensors entirely.

If you developed  the good habit of regularly checking your tire pressures, you might be inclined to run  your tires on winter rims without tire pressure monitoring sensors. However, putting up with a lit TPMS warning light on the dash may not be the only consequence of doing without sensors in winter. Important safety devices like the electronic stability control may be disengaged if the TPMS system is deactivated. Consult  an expert before taking this step.

DECODING MARKINGS ON THE TIRE SIDEWALL


 

(A): P195/65R15
P: this letter, which is occasionally absent, identifies the vehicle category the tire is designed for. P (for passenger) identifies that the tire is a passenger car tire. LT (for light truck), is a truck tire. AT (for all-terrain) usually an SUV tire with some off-road capability.

195: the width (in millimetres) of the tire from one side to the other. In general, it is proportional to the size and performance of a vehicle.

65: height of the tire sidewall, expressed as a percentage of the width (in this case, 65 percent of 195 mm, therefore 127 mm).

For any given width, a lower percentage of sidewall height indicates a lower profile tire.

Tires with a sidewall height 55 or less called “low profile” generally provide very good handling, occasionally at the expense of comfort. They cost much more than mainstream tires (a sidewall height of 60 to 65 or greater), and are often standard equipment on sportier cars. Low profile tires are also wrapped around large diameter wheels on high-end versions of compact and intermediate cars.

R: radial construction tire, which is virtually universal today.

15: the diameter of the wheel in inches. Fourteen inch wheels are typically reserved for the base versions of subcompact cars; 15 inch wheels are used on most compacts and on high-end versions of subcompacts; 16 inch wheels are standard on some compacts, intermediates and many compact SUVs; 17 inch wheels are found on sportier compact cars, intermediate SUVs and mid-range versions of compact SUVs; finally, 18 inch and bigger wheels are used on sporty SUVs as well as high-end versions of many cars. Wheels with a diameter greater than 16 inches are rarely needed on a touring car, but have become fashion items over the last decade.

(B): 91Q
91: index of the maximum permissible load. For example, an index of 91 notes that the tire can support up to 615 kg (1356 lb.). Never install tires that have a lower index than that noted in the owner’s manual.

Q: speed rating. Indicates the maximum speed the tire can roll safely for an extended period, assuming that it is in good condition and inflated to the pressure recommended by the manufacturer of the car it is installed on. For example, a Q-rated tire corresponds with a maximum speed of 160 km/h. Winter tires for touring cars and SUVs are seldom rated higher than a T (190 km/h).

(C): M+S
The M+S (Mud + Snow) legend indicates that the tire has wider than normal gaps between the treads than a summer tire. As there is no industry standard to define what M+S means, the level of traction in winter conditions is variable.

D): Snowflake inside a mountain pictogram.

All winter tires offered in Canada bear this symbol that denotes approval of the Canadian Rubber Association (CRA). In principle, it guaranties that the tire conforms to specific performance requirements regarding grip in snow, and that the tire is specifically designed for driving in snowy conditions. The standard does not currently include a test for grip on ice. Until recently, the snowflake on a mountain symbol was a reliable indicator of with winter performance of a tire. However, the standard needs to evolve so the winter tire designation doesn’t lose its significance, like the M+S symbol has.

Buying tires from the U.S.

Within reason, the APA would much prefer you source your tires locally. Among other benefits, the profit from the sale of the tires will hopefully support the expertise you may eventually need at a local retailer. Before adjusting for exchange rates and Canadian  promotions, published tire prices are frequenlty lower in the U.S. depending on the brand. For a few years, the biggest culprit was Bridgestone, whose wholesale price to Canadian tire retailers was sometimes higher  than the retail price in the U.S. For 2013, Bridgestone significantly reduced its Canadian tire prices to more closely align them with the U.S. market. The savings are smaller this year, and after adding duty, customs brokerage, and shipping, it's rarely worth ordering tires from the U.S. for shipment to Canada. View the APA's price comparison chart for more details.

Customs Canada duty charges are as follows:

Tires manufactured in North America, no duty

Tires manufactured outside North America, 7%

You will need to add the applicable Canadian sales taxes, and possibly U.S. sales tax if you are buying from a retail tire outlet. Mail order purchases will be U.S. tax exempt. Figure an additional $125-$250 for shipping and customs brokerage fees. Installation and balancing which are sometimes included in advertised Canadian prices have to be added. In an APA comparison of Michelin X-Ice Xi2 tires for a Honda Civic, the price difference for a set of four was only $15 savings on a US purchase after applying the Canadian mail-in rebate, not available on US tires exported to Canada.Tire Rack is an excellent place to start if you are thinking of sourcing your purchase in the U.S. Pricing and selection are very good; the website is full of information and fairly easy to navigate once you get the hang of  it. If you are planning to buy a set of wheels, they too can be added to your purchase from a large selection. Have a look at the Tire Rack website.

Most tire makers offer mail-in rebates on a set of four winter tires purchased in the autumn. These range from $40 to $100 per set of four  and are not usually offered to consumers residing outside the country of origin. This means a Canadian resident needs  to consider the potential loss of a Canadian mail-in rebate on the purchase of four tires in the U.S. Instant rebates, applied at the time of sale by the retailer, do not normally carry this restriction .

Warranty issues with name-brand tires are rare in Canada nowadays. They can be more of a hassle on US-sourced tires. The Canadian retailer may be willing to help, but backup depends on the Canadian distribution system for your tire. The tire's Canadian distributor  may be less willing to process a warranty claim in Canada for a US-market tire. In some cases, this will mean shipping the tire back to the U.S. for an adjustment.
