I found some nice GM accessory wheels, but a disclaimer was that they only fit 2007-2013 trucks, not the GMT800. Was there a change is offset between the 800 and 900?

Can someone supply me with a factory wheel size and offset from a GMT900?

Thanks.

 

Pics of said wheels?

I am running some LTZ 20's from the 07-13 trucks with zero issues, as are countless others. I'm sure offset and rim width may be slightly different depending on what wheels they are but they should fit just about anything from 99-14+ because the bolt pattern never changed.

 

No Difference that I know of between NBS and NNBS factory wheels ,

I actually run 05-06 NBS sierra Denali Wheels on my NNBS 09 Sierra Denali , everything is the same ,

And I run NNBS Tahoe LTZ wheels on my NBS 2000 Silvy , no probs again everything is the same .

Now in like 2011/2012 the 2500HD bolt 8lug Bolt pattern changed , so maybe that's part of your question/confusion

 

These are 6 lug wheels. I wonder if the wheel hub center on the GMT 900 is smaller than the GMT 800. That would cause a problem of using newer wheels on the older truck, but older wheels could be used on newer truck.

What is the diameter of the GMT 900 hub center?

 

They are the same center hub size if it's a 6 lug rim.

 

OK. I don't know why these wheels are listed for 2007+ because I have found many pictures of GMT800's with these wheels I'm looking at. So obviously they fit.

Ah.... It just hit me as I was writing this. Did GM start using TPMS on 2007+?

 

Actually they started in 2004 with the yukons/escaldes/tahoes/suburbans on some models but otherwise yeah GM started to use TPMS full time in like 2007. Likely the reason they say for those years only.

 

Sorry I never posted a pic of the wheels. Here they are, CK948 wheels. Now to find a good deal on some.

 

Will these (possibly 2018, 18" wheels) fit over the 4 piston calipers?

 

They should
