What are SAE Class S Cars for fitting snow tire chains?

Question

I want to figure out if I can use my snow tire chains from my old car on my new car. The storage bag for the chains says they fit SAE Class S cars.

Answer 1

Tire size must be known in order to select a tire chain of correct fit.

For passenger cars, vans and small pick-up trucks it is important to check the owner's manual.

The restricted wheel well clearance in most of today's down-sized and front drive vehicles may require  the use of SAE class "S" tire chains, as noted in the vehicles' owners manual.

Class "S" is a minimum clearance requirement set by some vehicle manufactures.

To determine if your vehicle requires Class "S" tire chains, refer to your vehicle owners manual (usually listed under "tire chains" or "snow chains") or contact the vehicle manufacturer or dealership directly.
