will 305/35/22 Verdestien tires fit on an '06 body? And if yes would they fit on the 22" formula techart wheels.

 

it should, another guy with 08 CGTS has it. The outside diameter of 305/35/22 is 30.4", the radius from the center to the top of the tire is 15.2" and when I measured and re-measured, it indicated that it should clear. That's why I ordered a set for my 09 GTS with Techart lowering module.

How wide is the Techart 22" that you have, if 10" - should fit.
