Need help with tire fitment, 1999 gmc Sierra

[Goldensierra]

So I have a 1999 gmc Sierra that has the stock sized 265/75/16 tires on stock rims, I just bought 285/75/17 inch tires on Craigslist, what will I need to do to comfortably fit them, do I need a full suspension lift kit or should I do something cheaper?

Are you using stock wheels?

 

If ya don't mind trimming, a level should be all you need. I fit same setup on my 03 and we area out to put that size on my cousins 95 Tahoe on in 16s for both.

My 99 silverado came factory with 265/75/16 tires.

 

I have run 285/75/16 tires for years on this truck (3 sets, 200,000 miles).

 

I did crank up the torsion keys to gain about 3/4 of an inch clearance.

 

I have had no rubbing issues.

 

A light rub will occur in the front, if I have the steering locked to one extreme left or right, and have the suspension limited out to an extreme also.

 

It has never rubbed in day to day driving.

 

285 work no problem on my truck.

You may be able to fit the 286/75R17 tires by just tightening the torsion bars to raise the front end. There still may be some trimming required because that is almost a 34" tire. I have 285/75R16 on my 96 K1500 and did nothing other than put the new tires on the stock rim. Just to clarify, you do have a set of 17" rims to put the new tires on? Or was that just a typo and you meant 285/75R16 tires?

Yes I do have rims to put the tires on, I just want to know how much trimming I would need to do or if I could just buy wheel spacers with a leveling kit, or are they actually as destructive as people say?

I don't think you need to go with a leveling kit at all.

 

Cranking up the torsion keys will net you an inch or slightly more without throwing the geometry off significantly.

 

Don't think you need to use wheel spacers with stock wheels either.

i bought aftermarket rims with the tires so they aren't stock wheels, wouldn't i need more than 2 inches to comfortably fit the tires underneath, my truck does go off road from time to time so i need to have a decent amount of travel, but i cant afford a full suspension lift.

The wheels currently on my 99 are by MB Motoring and have less back spacing than the stock aluminum wheels (they stick.out about 1" farther than the stock ones).

 

This provided more than ample room. Quite a bit more than the originals actually.
