I know that the 37x12.5 will fit the H2 stock with just a little torsion bar tweakage, but will
the extra inch width of the 37x13.5 rub alot more that the 12.5?

I really would rather have the wider tires on stock rims, as I like the look better.....anyone know
if I can pull this off without sabotaging myself?

I thought about wheel spacers, too.......bad idea?

 

i don't have stock rims, but my 13.5's don't rub the frame or sway bar in normal driving. the did rub the back of the fender well when i was at full turn, but they've worn down now and no longer rub. i think you'd be fine with either.

 

Are those the Toyo MT's on your rig? If so, how are they with road noise?

 

yes, they're toyos. much quieter than i expected, and quieter than the BFG MTs i had before i got these.
