I have a 98 2 dr Tahoe 4X4 and was wondering what the largest rim/tire combination I could install without having to add a lift kit.

285/75R16 which is roughly 33 inches. And with these you'll likely have some rubbing at max turning radius, or even during more gentle turns when your front suspension is flexing. Also will rub in the wheel wells if you hit a big dip and come close to bottoming out the front. This is just from my experience with this size on a '95 4x4. You'll also have to remove some plastic that fills the gap in between the bumper and front of the fender, although I can't remember if I had to shave off some of the air dam or not.

That's exactly what i needed to know, Thank you!

Just FYI, I have put 285/75/R16 BFG's on a 91 Z-71, 96 Z-71, and a 96 Tahoe (Factory Wheels) and have never ever had any of them rub on anything. They fit with no trimming or lifting.

Thanks for the info!

Yeah good point actually, thanks for pointing this out. I forgot to mention that in every case I've had oversized tires I've also had non-stock wheels which tend to stick out farther from the axle than factory ones (the technical term has escaped my mind right now, more spacing I think?)

how much does the 285 lift from the 265's? How much taller I guess.

I'm not in the math mood so here's this:

TD = 2 x (SW/25.4) x AS/100 + RD

SW=section width--the first number, 285 in this case: LT285/75 R16
AS=aspect ratio--the second number, 75 in this case: LT285/75 R16
RD=rim diameter--the third number, 16 in this case: LT285/75 R16

Math sucks!

My supercomputer tells me approximately 1 inch. That is, assuming that the end result is in inches and the supercomputer actually works. :screwy:

True, true. I got on a roll and ground these out.
265/70R16=30.6=31"
265/75R16=31.6=32"
285/70R16=31.7=32"
285/75R16=32.8=33"

I think the metric system is easier to use in just about all cases except tires.
