Nnbs Wheel Sizes

ryan_hermanutz · December 8, 2008

Ok I've tried searching for this but I haven't gotten any answers. I have an 08 Silverado and I'm looking to put on different wheel. I was under the impression that I could only put 17's or larger. I just called the dealership and the service manager told me that I could put 16's on if I wanted. Is this true?

No, not true. You need 17's or larger. I believe 16's were acceptable on the GMT800 trucks but not the GMT900(that's the correct nomenclature, not NNBS) trucks.

When I went and ordered my new "winter" wheels and tires, the tire shop told me the smallest they can go is 17" because of the clearance for the calipers.

I believe all trucks '05 and up can't fit anything smaller than a 17 (because of the larger front rotors).

Thanks guys, that is what I thought. I even told the service guy that the reason I thought that was because the brakes. He told me that the work trucks come with 16's and that the brakes are the exact same. I will take the words of you guys over the service manager, which is kind of scary that the boss doesn't know his stuff. He was probably a salesman that could hang so they promoted him. Any ways thanks for reaffirming that for me.

The half ton W/Ts come with 17s just like the rest of the half tons. I believe the HDs can still fit 16s though, but I'm not 100% sure.

I'm pretty sure GM doesn't offer a 16 inch wheel on ANY new trucks anymore.

Unless they make a 17" version of the same wheel, Brian's truck has 16s...

Well, you are correct sir. GM literature does list 16 inch wheels as base for the 2500. I went and looked. 17s and larger only on the 1500s.

WTF?

Then maybe I look into that a little more perhaps. If he is willing to let me put a set on that might settle the issue. I will call and see if he is willing to. But then the next question is are they the same steel wheels that I have now?

If you have a half ton, you can't fit anything smaller than a 17 without grinding the calipers (Brian's truck is an HD, I guess they never went to a larger brake setup).
