Stop in for a cup of coffee

Interesting... Never had a trailer. So, while I knew they made different tires for trailers, I never gave much thought to why. There are reasons not to swap either way. Just did a little quick google read... While most people know the trailer tire is not speed rated for a car (but seam to forget that when pulling a trailer) They also don't have as good of tread for both wear and traction. Going the other direction- car tires don't have the heavy sidewall that trailer tires do. This is to reduce sway.

Usually trailer tires are "C" tires, or so called reinforced tires. The C is sometimes also referred to as light truck tires. The old normal was that car tires had 4 ply's, while the C tires had 6 ply's. Which makes them stronger in the sides, and for a car they become a little stiffer to drive, but I have used C tires on a car and had no issues with that. Some of them may be a little more noisy than a regular car tire.
The biggest issue using trailer tires on a car I would say is the lower speed rating, around 80-85 miles per hour or something like that.
