does anyone know what the maximum tire size you can put on a stock '08 2500HD? I cranked my bars some to level out the truck a little but besides that, its just the stock suspension. I just want to know what tire will fit without rubbing.

Probably 285's are the largest you'd wanna run...I have 285's and they rub a tad on turns,only when in reverse though!!285's will be safe and you won't be comprimising your ride...I think 285's are the biggest you can squeeze on a stock wheel IIRC!!

Yeah, I had 285s on my '00 1500 Silverado. I was going to get new wheels as well though. Thinking about 18s. Not sure if I really want to go to the 20s. What tires do you run and are they on stock wheels?

I run 285/75/16 on mine and they are fine.They only rub when I'm in reverse and cut the wheel hard to one side or the other.STOCK WHEEL...If you're gonna change the rim size,then you'll need the correct backspacing so you don't have problems.What height and width wheel are you lookin at getting?I'd considered putting the 305's on at first[guy said he could def mount them]but I didn't want to have problems turning and such[with the width]..I 1st put mud terrains on and didn't balance them even one time.ummm[they didn't last but 12-14k or so]I have gotten me some all terrains[same size:285/75/16 and I love how quiet they are,seems they wear a hell of a lot better too!!!I'll prob get me 2 more new 285's and put the M/T's back on for winter.[case I gotta yank one of the bosses Powerjoke from the mud around the site]

the biggest on most GM trucks without any lift is a 285-75R16 or 285-70R17.if they do rub a little a leveling kit will take care of that.

I am able to run a 255/85 r16 on factory rims with a set of 2" torsion keys and i have yet to make them rub. Problems i am having though include the middles wear faster when aired up properly and availability(most stores dont carry this size). My brother-in-law is running Nitto mud grapplers size 33x12.50 (after market rims) with the 2" keys as well on his 08 but they rub excessively when he turns all the way.

12.5x18 with Toyo MT's soon. I had them mounted up about two weeks ago to check them out drove around the lot and meneuvered quite well with only a slight rub in reverse. I used the ready-lift keys to level mine.

If the middle is wearing faster,then you def have too much pressure in em!!

Just a heads up....if you run anything bigger than a 245...and plan on getting different wheels....you can rub badly. I put a leveling kit on my truck, got teflon wheels with I think a 0 offset rating, or basically a set that stick out the least and my 265's required me to do A LOT of plastic cutting.... But people who do it with stock wheels don't have issues because they suck in more. Also, there was a thread on here about bigger tires on stock wheels causing blow outs or something....you might want to research that.
