Gettin New wheels thinkin abou trunnin 3.75 backspacing. the rim is a 15x8 runnin 31's like to know how far they will stick out. im not runnin fender flares just trimmed up fenders.

Anyone Runin The same BS? Got pics?

3.75 to 4" ought to be good. Factory was 7" IIRC so they were OEM 7" wide rims too. So that will give you about 3.5" of more space between your rim and your lower control arms. Thats where your backspacing will be the most significant. Good luck. Bought my Soft 8s from Summit b/c they have free shipping and no tax for out of state buyers.

Look at my jeep, it is sitting at 4" of BS on 31x1050s. Yours will stick 1/4" further out then mine.

Once you do they will send you a catalog every few months and if you buy from them much you will get other catalogs from other suppliers. Some good and some a waste of paper.

Also you will get a nifty hat from them depending on how much you spend..

Guess I'm too cheap but I do have a Jegs hat I got along with an order I placed a couple years back. Never wore it. Wonder what I did with it???

My summit hat became a much needed working on the car hat.. It's black so grease doesn't show..

Kyle, is your rim a 8" wide?

Kyle

15x8 4" BS

Joshman503

Awesome Thanks.

Kyle

Not a problem at all.

Here's a question not to hijack or anything..Is it ok to run 30"s on a 15x8 rim? I do plan on 31's by years end but on 30's till then...

Kyle

Ya you will be fine, just dont be racing around in your jeep (not that you should with regular tire/wheels)

BlueXJ

The height of the tire should not be affected by the rim width. The second number is the width and that can be a problem.
