I just bought a 99 SLT Jimmy and didn't like the factory wheels it came with so i changed them for a different style. Here's my problem.....
it looks like the rear tires sit in more now than before. I bought a set of used rims and the guy said they were for a 4x4. The front seem to sit fine.
The 1st pic is what I had on before, the second is what's on the truck now.

Please help as I don't know if it's just my eyes.

Thanks

 

The old rims did the same thing. The rear track width is narrower than the front.

 

Is your truck a 2WD or 4WD?

 

I actually noticed the same thing after putting my winter rims on... I'm actually thinking of 1 inch spacers for the rear to bring them out a bit, but am worried about rubbing the rear fender lips when the rear articulates... I park in some pretty crazy spots at school lol...

Matt. I'd assume his truck's a 4x4 because he bought rims for a 4x4. Doesn't mean anything but that's just my logic lol.

 

it's a 4x4. So it's suppose to be like that? seems weird that GM would do that, make 2 different rims for the same truck with different offsets.

 

The wheels are the same front/rear. It's the rear axle that's shorter than it "should" be. They're all 15x7 with 6" of backspacing. (At least all 2nd gen 4x4 wheels.)
