Difference Between Trailer Tires And Automobile Tires

Question:

What are the differences between your kenda karrie 145/80-12 trailer radial tire and a passenger car 145/80-12 radial tire? I need some for a boat trailer 60 miles per hour. Are they interchangable? Thanks

The main difference between a trailer tire like the Kenda Karrier S-Trail Radial Trailer Tire, part # AM10130, and an automobile tire is that a trailer tire will have a thicker sidewall which is designed for increased load capacity on a trailer. Trailer tires are identified with ST, like ST145/R12.

Automobile tires are designed more for ride, comfort and handling. If you placed tires designed for trailers on an automobile, the ride would be very stiff and uncomfortable, and is not recommended. They may be interchangeable but would not be advised for the reasons I listed.

I have attached a link to a product review video for the # AM10130 you can check out.
