9.5 or 12" wide rim?

I'm sorry, I lost my mind apparently. I thought we were talking about going up to 37's.

My bad... 35's are actually 2" taller than stock tires. (even though stock tires say 35's, they actually only measure 33" tall)

2" taller tires will reduce the gear ratio a bit and on the highway, it's very possible you go up a couple of miles to the gallon. It would be like having 3.90's instead of the stock 4.11's.


Again, sorry for speaking out of turn, should have read the whole damn thing.

Oh...I missed that too.

Okay, so how do 37's do on 12" rims? I've got a Cognito Leveling Kit and am currently running 37" BFG Mud Terrains on the stock rims with no rub.

What should I expect if I move to 12" rims?

I have had no problems, but I have a fabtech on mine. 37" toyos with 22x12 rockstars.
