WINTER DRIVING

Tires that meet the Rubber Manufacturers Association (RMA) definition of snow tires are marked M/S, M+S, or M&S. On such tires, this designation is molded into the sidewall. Tires without this notation are not recommended for winter driving.
 
While All-Season tires are designed to provide reliable performance in some winter conditions, the use of four (4) winter tires is recommended for optimal performance. Tires designated for use in severe winter conditions are marked on at least one sidewall with the letter “M” and “S” plus a pictograph of a mountain with a snowflake on it.
 
Tires without this notation are not recommended for winter driving.  

DRIVING ON STUDDED PASSENGER TYRES – WHERE LEGAL

Only new tires should be fitted with studs. On studded tires use only Nokian recommended studs. When studding, follow Nokian studding recommendations. For maximum effectiveness, all four M+S tires on a vehicle should be fitted with studs. If only the two rear tires are studded, maximum efficiency in handling and braking will not be realized. NEVER MOUNT STUDDED TYRES ON FRONT WHEELS ONLY.
 
New studded tires should be driven in for the first 250 or 300 miles by avoiding rapid acceleration, high cornering speeds and violent braking. The studs will then be able to properly settle into their holes and will function correctly for the lifetime of the tire. New studs cannot be fitted to replace lost ones, as they will not stay in the holes formed in the tire. The stud holes are formed during the vulcanization process, by means of plugs in the tire mould.
 
To obtain maximum tire wear, it may be necessary to rotate your tires. Refer to your vehicle owner’s manual for instructions on tire rotation. If you do not have an owner‘s manual for your vehicle, Nokian Tyres recommends rotating your tires every 4,000 to 6,000 miles (6,500 to 9,500 km).
 
Monthly inspection for tire wear is recommended. Your tires should be rotated at the first sign of irregular wear, even if it occurs before 4,000 miles (6,500km). This is true for all vehicles.
 
When rotating tires with a directional tread pattern, observe the arrows molded on the sidewall which show the direction the tire should turn. Care must be taken to maintain the proper turning direction. Determine whether rotated tires require tire inflation adjustment as front and rear position tire pressure may vary according to the vehicle manufacturer’s specification due to the actual load on that wheel position. Some vehicles may have different sized tires mounted on the front and rear axles, and these different sized tires have rotation restrictions. Always check the vehicle owner’s manual for the proper rotation recommendations.

NON-STUDDED WINTER TIRES ALL YEAR ROUND?

Coarse spring roads can be particularly wearing on all tires, and non-studded winter tires are primarily designed and intended for winter use. Non-studded winter tires that have been unevenly worn by coarse spring roads are no match for good summer tires. Therefore, we do not recommend the use of non-studded winter tires as all-season tires. Summer tires are the safest and most economic choice for summer driving. Read more »
