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.
