Downtown Shell Knob MO Come Visit! | I agree. I had some super crappy 16.5s. And I was very close to switching them over to 22.5s. and at the last minute I went with some 16inch rims and some 16inch rv tires that are 14 or 16 ply and rated for , 3600 a piece at 120psi or something stupid high like that (but I was lucky becaue my axles were already 9/16 studded axles that were 15k rated and the rims I found out of pure luck were 3500lb 150psi rims. Otherwise it would have gotten 225/70 r22.5s I wasn't going to spending good money to switch axles and rims over to 17.5s or 19.5s just to end up with higher priced tires than I could get with 22.5s |
