I just bought some Pontiac G6 wheels I want to put 245/45/18 on it will they fit without rubbing the offset on the wheels 41mm thanks John B.

 

Here's a Great Tire Size Chart:

Don't think you should go over 235 x 45 x 18! Someone else might know exactly! Depends also are the G6's 8" Wide? Our 18" SS Cobalt Wheels are 7" Wide so we put 225 x 45 x 18"! Might Even Consider 245 x 40 x 18" if the Wheel is 8" Wide and you want the Width ?

Hope this Helps?

 

anyone know if 245/45/18 will work on the HHR?

 

Yes I know and No they don't to tall.
