I am wondering how different my car will look if I put 275/30/20 on the rear instead of my 285/30/20. anyone have a similar set-up on factory height? pics please...

your sidewall will be 3 mil shorter, so slightly larger wheel gap. other than that, not much difference. slightly narrower tire also, but i don't think you will be able to see the difference in that looking from the rear.

 

use this tire size calculator to play around. it doesnt look to be much different, however you need to make sure its less than a 3% difference between front and rear.

Why are you wanting to switch? looks like the sidewall will be .12" shorter and .4" narrower of a tire.

 

I rub a tad bit when 3 or more people are in the car and the shop I am getting tires at don't have the 285's in stock just the 275's

 

3mm taller is actually 6mm. Need to consider the total diameter, not just the added height on the radius. Anyways, 6mm is a tad under 1/4". I think the difference will be negligible.

 

by the way I am running 245/35/20 up front

 

IMO the 245/35 matches up well with the 275/30 but my answer to your wheel gap is needs more low

 

^^^more reasons to get some springs

 

I have 275/30/20 on the rear of mine. Let me find the pics and I will post them up.

Check out my garage for some pics.

 

So what's holding you back

In the picture of my signature I was on Eibach's running 245/275 if you want something to reference.

 

thats a sick ride already

 

Sorry I don't have pictures for reference, but my Summer Set of wheels run 245/35/20 and 275/30/20 without any rubbing problems, I originally wanted 285's but my tire dealer warned me of rubbing...I have the 37xS...nice car btw!

 

I got into photography and it is hard to pick between camera gear and car stuff your car look sick by the way. I think i will be getting some Eibach's real soon they are what I had planned to install orriginally
