235/50/18 BFG GForce KDWs. I got 'em too cheap to pass up. I will be upgrading to 255/45/18 in the future.

Yes you can on the front. Just be careful, b/c non stock Sidewall Aspect Ratios will throw off your speedometer and odometer (slightly) unless you can program in the custom size with a tuner.


Stock size for GXP are

Front - P255/45R18
Rear - P225/50R18

Do you guys think a 235 wide tire can fit on stock 16" gm alloy/steel wheels? 225 is the standard for them.

Michelin HX MXM4 P235/50ZR18's are the stock tires on the LaX Super.

On an 18" rim 235's will fit if the rim is between 7 and 8.5 inches wide, I believe.

Corny is runnin an 8" wheel if I remember right, that or 8.5". I wouldn't recommend 255's on stock wheels.

225/60/16. Running the 9c1 steel wheels with the chrome centercaps. Also wanted a softer ride. 18''s too harsh imo and put more wear on suspension components.

CenTex is right, it's an aftermarket 18 x 8" rim.

Sorry for the late reply.

I think those sizes best fit the wheel wells, when done correctly.
