Max Tire size on a Stock Height 2015 2500HD

Recommended Posts

Just got a 17' GMC Denali HD. Stock 20's want to turn up the forks on the front and fit 325/60r/20 bfg mud terrains. Will this work? Thanks. Off-road package and no mud flaps

Definitely way too big. I couldn't even get 295/60r20 to fit with my front end cranked up. I'm after market with a x9 instead of 8.5. I've heard some cases of guys fitting 295 and trimming and such... but that 325 won't fit.

Just fitted 305 55 R20 BFG KO2's on stock rims. No rubbing. No lifting. My truck now rides a whole lot better.

35 12.5 R20 on a Rancho 3.5 level kit. Only leveled 2.5".

 

MKW Wheels 20x9 +10 offset Toyo Open Country AT II Extreme

 

CV angles are almost stock angles. No blocks on the rear.

 

Removed the front plastic air dam.

 

Trimmed the rear of fender well and pinned the liner back.

 

No rubbing at full flex.

 

35s with no lift. :thumbs:

Recently put 35/11.5/20's Nitto Terra Grappler G2's .

Suspension Maxx 2.5 leveling kit with Bilstien Shocks.

 

Could've gone with 12.5s but erred on the side of caution.

Terra Grapplers ride pretty well.

Yes, those are much smaller then the tires that lots of us are running. No problem.

I think you'll rub at stock height. With a level, you should be fine.

Are you sure about that? That's basically a 35x11.50x18 (within fractions of an inch), which will probably need a level to clear.

Just installed 285/75r18 Duratracs, 2017 Z71, stock front, rear shackle lowered. Absolutely no rubbing and fills the front end right up.

Nice! I really didn't think that size would fit without raising the front end a little. Looks great!

Anyone got pics of the 275/70R18s?   Is it a general consensus that a 34X11.5 is the largest you can fit without touching the suspension?

Sweet ride!  I have the same truck without the bars.  I'm considering the same size Duratracs.  Still no rubbing?  Even at full crank?  How's the ride?
