Looking for some tire size help ....
 

Hey guys - I've got a stock 07 H2 and thinking about going up to the 37 KO2s from the 315/70/17s. Looks like it adds 2 inches to diameter (roughly rto 36 from 34). Based on what I can see with height and turn clearance it looks like it could handle it.

Anyone tried this out or have insight?

Thanks!

The KO2s are not sized properly.
I've mentioned this a lot, but I have the 35x12.5r17s and they sit at 33.5" tall. I've confirmed on a few different forums that the 37" version sits at 35.5". The 315 stocks sit around 34.4".

If you're looking for a real 37", look elsewhere. If you're ok with a 35.5" tire, then get the 37". I cannot recommend the 35" as they are undersized for the H2.

Thanks for the reply ...

I'm going to go for the slight bump up to the 37s (35s) and see how they work.

Thanks!

I have 37's on my truck with no lift and I get slight rubbing only when I back up and turn wheel to the right. Weird. I may adjust torsion bars eventually.

I'm thinking about getting the same (37s not BFGs) if i get new rims, is there a particular back spacing to look out for which should avoid the rubbing ? Am not a fan of spacers...

Kind of rough. you just have to trial fit them because they rub on some h2s and not on others.
