2011 Hd Wheel Sizes

[pknoerzer]

I was reading the latest issue of Diesel Power magazine yesterday and their comparison of the lastest 3/4 ton diesels from the Big Three. One thing that jumped out at me was they claimed the new wheels on the 2011 Sierra were because they have a different bolt circle than the old GM wheels. Can anyone confirm this? I want to trade my old truck, but keep the wheels (18"x9" - 8x6.5"bc) What bolt circle is on the new trucks?

I don't know the #s off the top of my head, but they are in fact new for 2011.

 

Edit: 8x180mm

wheel-bolt pattern to a larger 8-on-180mm (single rear wheel) or 8-on-210mm (dual rear wheel) configuration.
