Expert Reply:
A P225/70R15 is about 27 inches in diameter while a P225/75R15 is about 28 inches in diameter. They are both nearly 9 inches wide and fit a 15 inch wheel.
Both of the tires you mention are passenger vehicle tires as shown by the letter P before the size. The difference between trailer and passenger tires is the flexibility of the side wall. Trailer tires are designed to withstand the downward force of a trailer load while passenger tires have a softer side wall to create a more comfortable ride for passengers.
If you need a trailer tire, I recommend ST225/75R15 Karrier tire part # AM10303. I do not know how much your trailer weighs but the larger ST225/75R15 has a maximum load capacity of 2,830 lbs at 80 psi. Higher capacity tires can run cooler and last longer.
