Depends on the tire. the first numbers are the section width in mm, the second the aspect ratio in % (section width x aspect ratio =diameter) and the third the wheel diameter.

So my 205x75R15 LRD (2150 lbs at 65 psi) are 10mm or about 4/10" skinnier and 8/10" taller than the 215x75R14 LRC (1850 lbs at 50 psi) that came on it.

15" wheels are an inch taller than 14" and mostly come in two widths for 5x4.5 trailer wheels, 5" and 6". I would want at least 6" wheels rated for the same load as the tires.

Wheels, tires, and axles are an area that I feel that TM may have cut a few corners & am seriously thinking about swapping in a 5k #11 Dexter axle with a 22.5 degree drop (stock is a 3500 lb #10 axle with what appears to be a 10 degree drop and does not leave enough clearence in the wheel wells IMNSHO). This may require 6x5.5 wheels. I do not believe in just raising the coach .
