The classes are defined as follows: SAE Class S: Regular (non-reinforced) passenger tire traction devices for vehicles with restricted wheel well clearance. SAE Class U: Regular (non-reinforced) and lug-reinforced passenger tire traction devices for vehicles with regular (non-restricted) wheel well clearances.
What are S rated chains?
If you have a passenger car, you have to purchase snow chains that carry an SAE Class S rating. The rating means that these chains are meant to be used by front-wheel-drive cars with low ground clearances. The best snow chains for trucks may not be the same for small cars.
What are Class S requirements for snow chains?
SAE Class S This Class is applied to regular (non-reinforced) tire chains and cables for vehicles with restricted wheel well clearances. It has a minimum tread face clearance of 1.46”/37mm, and a minimum side wall clearance of . 59”/15mm.
What are Type S snow chains?
Class S tire chains are designed for use on vehicles with restricted wheel well clearance. I have attached a photo that shows the areas where clearance for Class S tire chains is needed. For the A dimension a minimum of 1.46inches (37 mm) between the top of the tire tread and the wheel well is needed.

Bearing both the M+S symbol AND the mountain snowflake symbol, winter tires have met specific industry-established snow traction performance requirements and have been designed specifically for use in cold weather and severe snow conditions.
Do m/s tires have snowflake?

How good is Model S snow?
Teslas handle well in the snow, thanks to their advanced traction control systems. However, Tesla regenerative braking can be hazardous on slippery roads and cause sudden traction loss if drivers aren’t prepared.

What are the different types of tire chains?

Why do Subarus do so well in snow?
Subaru’s Symmetrical All-Wheel Drive provides a foundation of balance in snowy weather, and is further enhanced by X-mode. When conditions get particularly rough, X-mode adjusts the engine throttle and transmission shift points to deliver power smoothly and provide the ideal amount of torque to each wheel.
Is Subaru AWD better than 4WD?
Crossover small or medium SUV All-Wheel Drive cars such as Subaru Forester that are designed for normal road use with occasional dirt or mild off road use generally use permanently engaged AWD systems. This has the active safety advantage of always having twice the grip of a driver selectable 4WD system.
Is Subaru still the best AWD?
Subaru AWD systems are great because they can provide more consistency than other All-Wheel Drive systems by constantly engaging in power distribution instead of only when traction has been lost. While Subaru 4-Wheel Drive is popular and reliable, customers have come to really love the AWD system.
Are jeeps or Subarus better in snow?
The Jeep Wrangler scores number one with a score of 9.2. The Subaru Outback achieves second (8.8), and Subaru Forester is third best (8.7).
