I changed them out and put on Goodyear Marathons- ST 225/75R/15- load range "D" @ 65 psi, the max weight rating on the tires is 2,640 lbs each x4. From what I can remember the Carlisle "C" range were rated at 1,840 lbs each x4.
If I read the info correctly, the "C" range tire is a 6 ply and the "D" rangs is an 8 ply. The Goodyear Marathons that I have were made in Canada.

rockwood06 (and everyone else)...

I am thinking about doing the same which is changing from ST205/75/R15 to 225/75/R15 on my Forest River Cherokee Lite 28A+. From the calculations I have done the 225/75/R15 is about .79 inches wider and about 1.99 inches taller (diameter). From "eyeballing" it, I think it will fit. Any suggestions or thoughts before I order the larger tires.

Oh, my main reason is I want a 10 ply tire vs a 6 ply.

Just had a major blow out on my trailer on my way home from Vacation. Had one a few months ago. Decided to do some research since I bought two new Carlisles t. I dug out all the paper work that came with trailer. Yes my trailer which I bought new is five years old..... What irritates me is the paperwork on the trailers tires are Carlisle but what have actually been on the trailer from the time I got it are Nanco. What is up with that? Did Forest River shaft me or did the dealer? This has been a learning experience on tires.

I am going for the gusto with load range E. If Carlisles are junk then at least I am going to have load range E to help compensate. I know there are G but that might be real overkill.

Let me chime in too, just took a Carlisle Radial Trail off my 09 Flagstaff 26 rbss purchased 13 months ago. Sidewall badly weather checked, kept pressures up and only had about 400 miles on it! Other 4 are out of the same batch so we'll see how they fare on 130 mile trip end of the month!

Have a 2001 27.5 ft. and had 2 blowouts that had Carlisle ST205/75/R15 on it in the last few years. Each blowout caused about $1K in damage. More I looked into it, I was not comfortable with the max loading for the tire and the dry weight of the camper. With it loaded it was right near the max for the tires. I went ahead and replaced all 4 with ST225/75/R15 tires. Now this caused me to do a little modification to the Fender molding to gain clearance (took a cutoff grinder and took the lip off for 2 to 3 inches on the front leading part of the molding). Have much better saftey margin on the tires now, which should translate to running a little cooler also. One note when changeing out the old tires found that the steel rims had actually bent a little from the force of backing into sites (every watch the twist in the axels and tires as you back up, will make you cringe) . You may need to take that into consideration when buying tires also, that you may need a rim or two.
