uno Posted May 30, 2009 Report Share Posted May 30, 2009 so im slightly confused about new wheels and tires for my 2007 SGT i want 20 in wheels. so as i understand it, if i buy 20x10 rear and 20x9 front my tire size will be 275/35/20 rear and 255/35/20 front? Will i need spacers with this setup assuming i have the stock brakes that come on an 07 SGT also, do i need the tire pressure sensor kits, and what is the bolt pattern on an 07 SGT.

GT500-07 Posted May 30, 2009 Report Share Posted May 30, 2009 tire size will depend on the wheels backspace and offset. some run 275/35/20 on the front and 305/35/20 on the rear. Link to comment Share on other sites More sharing options...

The above tire sizes will be fine, no need for spacers. The bolt pattern is 5 @ 4 1/2. Offset needed is +30 (front), and +45 (rear). The correct backspacing is 6.18" (front) and 7.27" (rear). Yes, you will need new tpms sensors unless you use the old ones. You will need new bands either way. Chris Link to comment Share on other sites More sharing options...
uno Posted May 31, 2009 Author Report Share Posted May 31, 2009 thank you chris, one of the wheels im actually looking into are the same ones you have, the CS69's. But hopefully in a 20 if they make it. Also does the +35 and +45 mean AT LEAST 35 and 45 or it needs to be that number exactly? hmm perhaps find a wheel i like and ask a Les Schwab how it will fit (biggest tire and rim shop around here in Northern California) Link to comment Share on other sites More sharing options...
