I run 35s on my power wagon. I have never once felt a desire for 37s that wasn't based purely on aesthetics. That desire quickly goes away when i think of additional cost and having to deal with a 37" spare. I also think my 35s look great, unless maybe parked next to one on 37s.Thanks for the advice and info thus far. @GreggNY I think you nailed it with the capital IF. I’m planning to use it a bit and see what our true needs are before a decision on tire changes. 37s would require a method to carry the spare and new wheels, plus the price of those tires. I think for now our bang for buck will be in actual trips and some of the other mods that will make camp life better for the whole family. I’ll keep doing research (as is my nature).
