tire size?

[highchevy]

My mother-in-law is purchasing a new 2004 2500HD 4x4 and wants to put 285/75/r16's on it with messing with the torsion bars. Will this work Thanks for your help!

I put 285/70/17's on my 2004 GMC 2500HD regular cab 4x4. I did not have to mess with the torsion bars, but I did have to trim the front bumper and the inner splash guards. If it is done well you can't tell they have been trimmed.

Put the tires on. I bet they don't rub going forward. Mine only rubbed while in reverse with the sterring wheel cranked one way.

Did they rub on the front bumper or just the plastic fairing below the bumper?

[THE BIGPUNN]

rubbing is on the plastic fairing or inner splash guard, not the bumper itself.

No problems with mine I did not trim the plastic on my truck and did not mess with the torsion bars (yet). I want to do the torsion bars to make it look stout, not for the tires.

I just added 285/70/17's to our Z71 Suburban...they fit fine w/ no adjustments. I also ran 285/75/16's on our previous Yukon XL - no problems

it make a differance what make you got chev or gmc.

the chev lower bumper sheild is alot smaller than the

gmc.i have a 2004 gmc cc d/a and i put the 265-75r16

on it and on half turn the tire is about 1/8 inch if not closer

to the lower bumper sheild i would think you would have to

trim it but mine is painted and i did not want to its up to you though

. I would prefer tha larger tires but not worth the hasle just my 2 cents

good luck

Yea I heard the GMC is a little different. My chevy didn't rub the bumper. Just the plastic inner splash guard. I didn't crank the torsion bars either.

Here is pic of my 2004 2500HD with 285 Revo's and t-bars cranked. Tires do not rub at all.

With the 285/70/17's on it I had to trim the front bumper and the inner splash guards and use zip ties to tie back the back side of the splash guard. My truck is a 2004 GMC. After a little modification they look just fine and fit just fine. Just be careful if you have to trim something so it doesn't look bad when you are done.

 

I had the tires on a 2002 Cadillac Escalade and they fit tight, but just fine and I did not have to modify anything.

 

P.S. The 285's will look MUCH better then the little tires the truck comes with.

So is the general conclusion here that 285's will fit on the Chevy's without rubbing but not on the GMC's. I have a 2000 Silverado and im goin to be buying a set of Dueler tires. I was going go with 265's because i heard that the 285's rub. If the 285's don't rub i would rather get the 285's over the 265's. I just want to know before i go buying the tires if the tires are going to rub really bad or not. Thanks

I don't agree with that. I modified both a 2001 GMC Yukon XL and a new 2005 Chevy Suburban Z71 and both setups were exactly the same. I just think it's the small differences of the inner plastic wheel well that cause some people to have to modify and some not.

 

For example - over on a specific Z71 related forum - some folks had to crank the T-bars or zip tie the plastic in order to fit the 285's. My 285's on the Suburban fit perfectly w/out any mods. I can only attribute that to variations in the plastic molding while it’s being made at the mfg.

 

Another example comes from the sales guy at Discount tire – before installing my 285’s he indicated that sometimes they fit fine on an exact same year and model truck and sometimes they have to modify. He had zip ties on hand just in case.

I have access to a shop to mount the tires and stuff. I think my best bet is maybe to order one or two 285's put them on the front of the truck and put on the ground turn the wheel lock to lock and see what my clearences are and what has to be done if anything.

You are talking about a Yukon and a suburban. The 03 and up GMC Sierra's have a completly different front lower air dam. The Chevy's(regardless of the year) ends straight down where the 03 and up Sierras is one solid painted piece that curls under much farther. You have to do some trimming on the Sierras even if the T-bars are cranked to fit 285s. If you don't crank the T-bars you will have to trim even to clear 265's. Believe me I have an 03 and I have run 265s and now run 285 BFGs. My T-bars are cranked, the lower air dam is trimmed, and the inner splash guard is trimmed. They still rub on hard reverse turns and hard binds. Others mentioned 285/70 R17's which are a hair shorter than 285/75 R16's, which I am running. I forgot to mention that I have 8 inch deep wheels with the factory set posative offset. If you run the factory wheels you may eek by with less trimming on the front. Never the less I had the 285's before I put custom wheels on my truck.
