2008 lmm work truck tire size

My first post, I recently bought a 2008 2500hd work truck. It’s time for tires and I’m wanting to go with a bigger tire than what’s on it now. Currently it has 245/75/r16’s and I am wondering if the rims are wide enough for 265/75/16 or maybe even a 285?

Yes, you may have to turn up the torsion bars if you go with 285's.

Perfect thankyou, I ordered a set of 285's. Are they gonna be hard to adjust or is that something a tire shop can do when installing tires?

Maybe, truck has to be jacked up with the tires off the ground to adjust them and then an alignment should be performed which should be done anytime new tires are installed anyways.

If it came with 245's then the rims might not be wide enough which they are probably about 6 1/2" to 7" wide.
285's require at least 7 1/2" minimum width, most tire shops because of DOT guidelines will NOT install tires on a narrower rim than what is required for safety.
265's require a rim at least 7" wide any narrower then you might not be able to get them installed.

You can get on pretty much any of the tire manufactures website to view all specs including required rim widths for every size tire.

285's you'll probably have to crank your torsion bars as mentioned above, I had to crank mine 3 1/4" for clearance, then ended up getting a 4" lift..
Been there dealt with this.

Well finally got my tires installed & went with toyo 265/75/16’s. Rims were surprisingly 8 wide so had no issues with fit. Thankyou for the help.

Good choice with the 265s...save those front end parts.

So much truth in that! I'm sooo glad I outgrew larger tires and leveling front ends.
