I heard plenty of people has pull this off successfully, as long as the rolling diameter is close. Can someone explain this to me in somewhat of detail? and is there a calculator online to calculate this?

Just as a example: AWD; 20x10 +40 front 20x11 + 20 rears

^^ asking for bad news?

or what would work; 20x10 +40 front and 20x11 +10 +20 +28. assume none?

It's not the wheel width that's an issue. It's the tire diameter that needs to stay close from front to back. A wider tire in the rear needs a lower profile(sidewall). Google "tire size calculator" for a useful tool. Pick a tire size that matches diameter as close as possible.

Im still learning offsets and other things related to these crazy wheel setups.

How would I enter this correctly with the tire size calculator? just to be sure im not fooling myself lol

So I entered 235/30/20 and got a tire circumference of 80.271

then entered 245/30/20 and got a tire circumference of 81.012

off by 0.741, is this to much or no for AWD?

Schmexus

That's really not much of a difference and shouldn't be a problem at all.

Keep in mind that 245 tire is going to be stretched pretty far on a 10-11" wheel. Some people like that look, but I think it's ugly.

I am trying to wrap my head around the point of this.... do people really give up handling performance for the sake of appearance?

you want the 245/30 for the front tire if its a 20, that is close to the stock diameter. if your off by 2% you will risk damaging the center diff for the AWD

Schmexus

Why would the difference between stock and aftermarket matter as long as the tires are the same diameter from front to back?

A 245/40/18 is pretty much exactly the same diameter as a 235/30/20.

Schmexus

245/40/18 - 235/30/20 0.6% difference

245/40/18 - 245/30/20 0.3% difference

there are several reasons why you want to keep it as close to stock as possible:

A) so it does not throw the speedometer off
B) rack up additional mileage (both of these points are minimum but do affect the car)
C) so it does not damage the center diff. you could throw 36" mudding tires on your GS and have them all the same size but that doesnt mean it wont damage your car

Schmexus

A 235/30/20 is NOT going to destroy anything. It's almost exactly the same diameter as the stock tire.

You won't rack up additional miles unless the tires are smaller than stock and they would have to be EXTREMELY small for that to matter. We are talking about .6% so over the course of 100,000 miles you're odometer isn't going to be off by much.

Chances are your speedometer is already slightly off from the factory, but the speedometer gets its reading from the transmission, not the front tires. A 36" mud tire on the front of your GS isn't going to have ANY effect on your speedometer or odometer. You will have other issues to worry about though.

This is a good thread, I thought I knew something about but it seems I know little.

I'm interested in your information because I'm looking for 20 inch wheels with low-off-set. I love that look. I found out yesterday that low off set may NOT be an option for me, but yet I've seen so many GS show cars having low/negative off set wheels.
I DO NOT want to airtek suspension and I don't want to roll the fenders - mainly bcuz I can't afford all that. I just want to keep the outside stock with 20 inch low off set wheels.

Also, based on everything you all said, the tires have to be right bcuz I deff don't want to *** anything up.

So any advise and or suggestions you have would be valuable. Thank you.

^^^ It depends on the wheel width and tire size. Nobody can tell you what offset is going to clear without that information.

Unless one is looking for a deeper dish look out back why not stay with a non-staggered set-up?

you can actually still run a non staggered setup and still have more lip in the rear. ive seen AWD guys do it all the time(audi, subaru, evo). same widths front/rear, but lower offset in the rear to "appear" staggered but its not

im just merely passing along experience and info that ive learned through many of the wheel gurus that have passed through this forum. take it for what its worth
