03' Silverado 4x w/ 255/75R-16's and No Lift?

I want to get some ground clearance, but I'm not willing to spend $1800 minimum for a 4" lift. There is no smaller lift. I don't need a big flotation tire for sand or mud, I just want clearance for rocks on fire trails.

The tire guys say I can replace my 245/75R-16's (30.7" tall by 9.8" wide)with 265/75R-16's (31.9" tall and 10.5" wide). But he didn't know about 255/75R-16's (33.3" tall by 10" wide).

The 255/75R-16's would actually be a bit wider, and a lot taller. Any idea if they are going to fit?

I believe that the 265/75R16's are wider and taller than the 255/75R16's.

Actually it is width/aspect ratio/rimsize. The aspect ratio is a percentage of the width. With a width of 265, a 75 aspect ratio would put the height at 198.75. (Note this is just the sidewall height and obviously not overall diameter.)

Correct, the sizes are as follows: P265/75 R16 Tread Width = 10.4" Diameter = 31.6"

P255/75 R16 Tread Width = 10.0" Diameter = 31.1"

My 1999 Z71 came with the P265/75 R16 as standard so I would imagine they'll fit an 03'.

Hi, BFG has a size 255/85 R16 that's a bit over 33" It's a tall/narrow tire; it comes in the Mud-Terrain tread. Had 'em on my 94 f250 with no mods, other than the bumper ground & shimmed forward. Casey

255/75R16's.

Yea.. Your right. I MEANT to put 255/85R-16's. I typo'ed the size. The 255/85R-16's (usually only used on Dualies) are the 3.3" tall by 10" wide I was meaning to talk about.

The width shouldn't be an issue, only the height might be an issue on a unlifted truck. And probably only an issue on the front.

Anyone put those on a 1/2 ton 03' or up Silverado?

Again with a typo!

255/85R-16's, 33.3" tall by 10" wide (if on a 7" rim).

Tall and thin...

But still a hair wider than the stock 245/75R-16's.

245/75R-16's, 30.7" tall by 9.8" wide (if on a 7" rim).

Seems to me that if you increase overall tire diameter by 1.2" (30.7"

-> 31.9") you are only raising the lowest point fo the diff .6". Don't know how much extra ground clearance you are looking for, but .6" isn't that much.

It's going from 30.7" to 33.3" to get 2.6" taller tires. So, that's

1.3" more clearance. That's just about enough ;-)

I have 255/85R-16'BFGoodrich Mud Terrains on my 2003 1500K Silverado. That's 33.3 inch tall, 10 inch wide. That is the TALLEST tire that will fit without a lift. They look like they were made for the truck, and lifted the ride height up over 1.5" from standard height.

I can turn to full wheel stops, and go over big bumps, and they don't rub at all. But, that's because they are fairly narrow tires.
