2500 HD tire fit

Any ideas from the listers about what size tire will fit the 2500HD chevy trucks without body or lift kit. Tires than came with it look tiny, and measure only about 29 inches high! Thanks Rr

285/75R16 (33x11.25R16) or 305/70R16 (33x12R16) will fit on the stock rims without any rubbing. Lots of people do it. Don't put them on rims wider than 16x7 and with less backspacing than the stock 5.25", or they will rub. Bad. Can speak from experience on that one.

Re: 2500 HD tire fit

I have the same truck and posted the same question a month ago. Unfortunalty the stock rims are only 6.5" and therefore a 285/75 is about the max size for the rim and wheel well. I went with BFG AT, look and ride good.

Re: 2500 HD tire fit

Looking at a 17 or 18 inch wheel, not sure about the backspacing, where exactly does it rub. Im looking at ordering a 2003 2500 HD duramax/allison. I would like to go with a 305/70R17 (32.7" tall). Looking for a little more width than the standard rim ( more offset ?). Also, would slightly increasing front ride height by an inch through the torsion bars make a difference ?

Re: 2500 HD tire fit

Nine months ? I am currently being quoted about 20 weeks max. Don't want to order until I see one though. stock tire size is a bummer, tire fitting will be a challenge. dont want to void the warranty with lift. heard ford may put their power stroke 600 in the super duty's for 03 ? may change my mind in the mean time to get the solid axle !!
