Hello,

Sorry if this has been covered in detail. I searched and did not see anything on this topic. I have a 1999 2500 Suburban 4x4 and I have already purchased alloy HD chevy rims (later model pick up). I would like to mount 285/75/16's. These tire would basically be equal to a 31" tire. What would be the pro's and con's? I know that some of you already run 265/75/16's. I do not intend on lifting the vehicle.

Thoughts?

285/75r16's are equal to a ~33" tire. In order to fit that size tire you have to lift the truck. (unless you had a typo and meant 265 :D).

265/75r16s, You shouldn't have to lift the truck... IIRC my old roommate had a stock suburban and put 265/75r16 MudTerrain tires on it, looked good and fit well :).

I run 265/75-16's and they can rub if I am careless. But they only just touch my fender flares with the whell locked all the way to one side and then hit a good sized bump.
You will have to lift to run those 285's or at least crank the TB's all the way, which is a bad idea.

I used to have BF goodrich AT 285's on my 1500 4x4 with no lift. I could see a little bit of rubbing on the lower A arms but no rubbing on the fenders. Didn't seem to hurt the tires though but I mostly was doing on road city driving. If you are driving over a lot of rough terrain you might need a lift.

Another thing too is the 285s are a bit wide for the rims and they bulge up a bit in the middle as a result and might wear a bit funny. I sold the truck before I noticed this though.

The 285 tire is to wide for the PYO alloys. Also reduces braking capacity, beside the rubbing the body/frame. Not a good idea in my opinion!!!

The Extra Width and Weight Suck a mile or 2 per gallon even after they lower your RPM.

i am running 315's with a body lift, and they barely rub,only on max turns over bumps. i didn't notice any braking or fuel mileage decreases

I'm running 285 Yokohama Geolanders on my old 99 and they don't rub. Then again, I do have the Torsion bars cranked so much that the truck always looks like it's carrying a load.

my 265's fit perfect. they will only rub if its turned all the way and i hit a bump. i wouldnt go any bigger without a lift.

Same thing with me on 265, rub a little when turning and bump. If you want to put 285, make sure you buy new wheels at least 8" wide wheel also and lift it up a bit unless yours is lifted. Also, may want to adjust the vssb.

I have run 265/75-16s since the original tires wore out. I have very little rubbing, like others have mentioned. It only happens on the right front with the wheel turned all the way over. Once the tread wears down a bit, it quits. I have tried heating the inside edge of the flare to bend it, but it doesn't work too well. Very, very minor problem anyway...

I doubt you'll be happy with the 285s, as they WILL rub somewhere and irritate you for a long time.

On the 95 2500 6 lug, 285's rubbed (Had the chance to try out a buddies tires, so I did) They rubbed a bit.

But now on a 2500 8 lug (a buddies I worked with) no lift, he had 285s, and never had a problem with rubbing, and we damn near did everything but launching it.

Maybe since the 6 lugs and burbs sit a bit lower then the 8 lugs, thats where you guys see the rubbing.

I'm still gonna go get 285's and run with no lift... until I get around to a 4" lift.

I run 285/75/16 Buckshots on stock wheels for my 8 lug Burb. I can't get them to scrub and we've got our fair share of deep holes in Georgia.

Maybe since the 6 lugs and burbs sit a bit lower then the 8 lugs, thats where you guys see the rubbing. I believe all 6.5 Suburbans are 8 lug, even if it's a 1500

285 is too wide for a PYO rim, but a lot of people do it anyway. My dually has 6 inch wide rims so I was limited in tire choices, I wanted to go as tall as I could. The book said it was a half inch too wide for my wheels, but I went with a 255/85/16. Works out to a 33x9 roughly. May want to consider it, since it is probably the width and not the height that will give you the rubbing problem.

I guess I worded it wrong, I was talking 6 lug, and 8 lug as far as the 2500 4x4 trucks go, didn't mean to make it seem like I was implying the burb was a 6 lug.

I have no clue as to how the bolt patterns go on the burbs, they don't fallow the truck rules, the trucks are simple to figure out :p:

The factory alloy 8-lug wheels are 6.5 wide. Anything wider than 265 is going to curl the tread. Look for tire mfg. recomended rim width.
