Question:

My horse trailer currently has 235/70 r 15 tires but we are having a hard finding them. What would be the equivalent to that tire? Thank you

I'm guessing you have passenger vehicle tires on your trailer. Trailer tires are constructed with a thicker sidewall to withstand the vertical load. I recommend using 225/75-15 size tires.

I recommend the Provider, part # TR225LRE, which is about a 1/4 inch taller and 1/2 inch thinner than your current tire. They'll fit on your same rims you just need to make sure you have enough clearance for the additional height but more than likely you will. You want at least 3 or 4 inches between the tire tread and the underside of the fenders to avoid contact between the two.

The Provider has a maximum capacity of 2,830 pounds when inflated at 80 psi. It also has an 81 mph speed rating, which is higher than a lot of trailer tires.
