I have the opportunity to aquire a set of 20" 2007 Tahoe wheels/tires and I was wondering if anyone knew the specs on these wheels. What is the backspacing and bolt pattern? I'm pretty sure they have a 6x5.5 pattern but I don't know the backspacing? Are they similar to the Silverado SS wheels? I just want to make sure they won't stick out too far past the fenders. Any info would be appreciated.

 

Bolt pattern is the same. I believe they have more backspacing than stock gm 20s previous to them, could be wrong though so let someone confirm.

 

+1 on the bolt pattern. Offset is 31mm.
