Hopefully you have 2 axles, thats a lot of weight for 15 inch tires.

I have used carlisles 15" radial rh tires on my 5th for 2 years now and have made several cross country trips with the 5th sitting for many months at a time in between runs. They definitely run much cooler than any other trailer tire I have used.The big thing to remember is make sure your tire is sized correctly for the intended load. A 15% to 20% load capacity bigger than you need is a wise move. You really dont want to max out a tire. Heat is the number 1 killer. And be sure to use tire covers while you sit. the sun is the number 2 killer.

A 7000 lb trailer equate to 1750 lb per tire requirement.

A ST225/75-15 C = 2150 lbs capacity or 8600 lbs gross. A good match especially if the trailer sits a lot and makes short local trips but as any ST your limited to 65 mph.


A ST225/75-15 D = 2540 lbs per tire or 10160 lbs gross. Not a good match for a 7k trailer.

IMO your best upgrades will be going to a LT or a multi position tire especially if the trailer is on the road making you a living and long trips.
Depending on room in the wheel well and proper wheel pressure/wheel width requirements the Goodyear Wrangler HT in a LT235/75-15 C (50 psi) at 1980 lb capacity. Most LT tire makers carry this size.

And a Wrangler HT in a LT215/75-15 D (65 psi) at 2090 lbs capacity.

Maxxis LT U-168 are a commercial grade tire with several 15" sizes and have became popular with all types of trailer owners.

Vanco 2 from Continental another popular tire for trailer users has several 15" sizes and load capacities.

I see the Yokohama RY215 in a 700R 15 D at 2040 lbs capacity is popular on some of the other RV websites.

Do your home work on the numbers.
