Question:
what is the difference between st205/75R15 versus p205/75R15?
asked by: David M
Expert Reply:
The difference between the two tire sizes is the application the tire was intended for. Tire sizes that start with ST are intended for use on trailers and tire sizes that start with P are designed for passenger vehicles. You shouldn't mix the applications as the tires are designed differently for their intended applications. If you have a trailer you are looking for a wheel and tire for you should stick with an ST205/75R15 size like the part # AM32156 that you referenced. This setup is mounted on a wheel with a 5 on 4-1/2 inch bolt pattern.
