Just as the title says, I need to figure out what kind of profile I should run on the stock 18 inch Touring wheels. I know that I will run 255's all the way around, but I need to know which profile looks better and performs better. Pics would VERY appreciated. Thanks.

fr 255/40 , 275/40 rear. Dont change the wheel diameter.

Sportec

if u are going to have 255 rear make it /45 and u are going to be only +9mm off spec. 255/40 is going to be -17mm off spec and it is a lot!

Can you please elaborate when you say 17 mm "off spec?"

Get the combination that is closest to stock Wheel Diameter. Stock wheel diameters are:

25.8"Front
26.8"Rear

Why exactly does it matter? I'm not worried about extra space in the wheel well. I'm already dropped an inch. I do not have VDC. Is there any other reasons to not run 255/40/18 all the way around?

barthelb

If you don't have TCS or VDC then the only thing it will affect may be your speedometer. But it won't be affected that much so I wouldn't worry.

Awesome. Thanks for the info. The tires will be mounted Saturday. I will be running BFG g-Force KDW-NT 255/40/18 on all four corners. This thing should grip!
