Any advice or pictures would be helpful. The truck is an 04 2500HD 6.0L. It has a 6-7.5 superlift full drop. Exhaust, volant and blackbear on stock 4.10 gears. It towers, imho, over 325/60 20s (35.5x13.3ish) Terra Grappler on 20x10 Helo Maxx 8s with i think 4.5BS, the tires, even flexing and offroad, never rub. The truck is cranked level and has almost flat CVs.

Gas mileage is a repetitive 10.50-11.00 MPG with 99% in town driving.

The question is: with a 37/12.50 or 37/13.50 tire...will it rub the hell out of the truck and will it absolutely kill my mileage and or drivability of the truck.

im looking at either toyos (37/13.50 20), MTZs (if i stick with a 35) or a 37/12.50 20 Pro comp Extreme MTs..

any help...words of adivice..leave it on 35s? dont run pro comps? the truck in the next few weeks will be a weekendish toy. I should be getting an fbody to DD fairly soon!

looks perfect on 35's imo. I would go with 35 MTZ'S

I think it looks awesome with the 35's on there man...I think going with a wider and beefier tire would really set the truck off and it would keep you from HAVING to regear

I would regear to 4.56 gears anyway. Your MPG would improve.

i think 36x15.5 mtz would look tits on your truck
deff been considering that....i was worried how they would wear on a 10" wheel. and id think id have more trouble clearing those than a 37/12.50

i think beefy is the key...the tires are already pretty wide compared to most...they spec out at 35.2x12.91 off nittos site.
