Default 275/35 Rear Tires

If anyone is running 275/35 on the rear, what offset are the rims?

i am on a 19 x 10 +38 offset, slight fender roll....(maybe 1/2 inch of the fender rolled)

What are you putting on? I would list the rim and offset you are looking to go with for others to help.

I'm trying to find out how low of an offset I can go without modding, with no drop.

if you are not going to lower then you are okay! You can go more aggresive on the offset then i did then if you are not going to lower. I would play it safe just incase you do drop IMO. With what i am running you would see minimal rub on the rear..i porbably didnt need to roll the fenders but had them done for almost nothing.

i have 235/35-19 for the front. I have more detailed infor on the last or 2nd to last page on the wheel thread. I would look at others set ups in there to see what you like. IMO 19" since you are not going to lower will flow better with the car. But its all up to what you want!!!!

Any rims in mind??

I don't have any particular wheel in mind yet but I want to stay as close as possible to the stock specs (tire diameter). I will keep the front stock size wheel and tire (225/40/18), but a more aggressive offset. On the rear, I want use the widest tire I can and stay as close as possible to the stock diameter and lowest offset, at stock height.

Both my front wheel are damaged (rim dents) and one has a slight crack (all from average pot holes). I want a strong set of wheels that can handle average pot holes or a decent looking cheap set that I can toss when they get damaged. I've damaged both 18" front wheels, so going to a 19" is out of the question. I would even consider a 45 on the front for the extra sidewall, to help protect the wheels, if it didn't sacrifice handling.

sounds like you need to stick with 18" if the potholes are that bad in your area. go to tire rack or discount tire and look at Plus sizes for your rims? they have a chart and info that will of help. another option is to find the OEM rims here or ebay and just plus size the tires on them?

How low of an offset do you think I could use without rubbing (with no drop)?

if weather permits tomorrow i will have my rims on so you can see a pic of where they sit. Depends on how far out you want to go. since you are not going to lower you can get crazy but IMO i would stick with the fender lines. I would read thru the wheel thread to see what others have done. also maybe send JavyLSU a PM to see if he has some info for you or SincityIS. SincityIS is who did the set up and they can provide you with more info then i can on how extreme you can get, again its preference. you can see my stuff after pics to see if that works for you. my setup will work with no drop! you could also lower down the road if you wanted

Thanks, I had already read the 1500+ posts on wheel set-ups and there was nothing there that could really help me. From what I did read I THINK I could safely use a 35+ on the front and 40+ on the rear (which is a 10mm dif).

Thanks for the info, you're using a smaller diameter tire (30), are you dropped?

im pretty sure he is dropped. you should go with a 35 series on a 19" unless you are dropped and avoiding rubbing issues.

no go for me today...its snowed in IL so picking up the tires and putting rims will have to wait till sometime next week.
