i noticed that the best setup for a staggered setup on a gs is 245/35/20 on the front and 275/30/20 on the rear.

why is it that the rear has a lower profile tire then the front tire? Should it not be the same profile on all tires?

This article will help you understand tire sizes

but in short, the height of the sidewall is a percentage of the tire width. The first number is the width, the 2nd number is the percentage. In a staggered setup, you are trying to keep the overall height of all the tires as close as possible. The wider the tire, the shorter the sidewall needs to be in order to maintain the overall height

toyemp is correct.

245x0.35 = 85.75mm
275x0.30 = 82.5mm

I think you meant the smaller the profile (i.e percentage). The sidewall should work out to be the same in a staggered setup. I am assuming you are using "width" and "wide" to refer to the same part of the tire spec.

ok. Well, I know what I meant to say, just didn't say it very well.

I see a lot of folks on here using the same profile tire on front and rear. Why are they not using a lower profile in the rear?

the ideal staggered setup has the same overall diameter or very close to it between front and rear tires even though the width's are different. I run 255/30/22 and 305/25/22 tires, but the overall diameter is identical as well as the sidewall height. The middle number or aspect ratio is essentially a percentage, but overall diameter and sidewall heights is what you need to focus on to match up. This is extremely important for a car like mine that has All Wheel Drive

Edit..whoa, just realized how old this thread was lol
