Dear Tire and Wheel Scholars....
 
I got my jeep and he needs new shoes.

275/70/18 duratracs with 18x9 wheels?

Stock 2012 Sahara Unlimited, no lift. I don't know what spacers are but some people apparently need them, would I?

Is this a good combo and would I assume this shouldn't rub on any part of my car (no off-roading for me)? cutting is definitely not an option.

Thank you :thumb:

I don't know about your car but on your Jeep if that is the tire size your looking at the 275/70/18 is 11in wide for the duratrac. A tire that wide with stock wheels will mean your gonna rub without adding spacers or changing to new wheels. You might be able to get away with just adding washers to the steering stops but that Im not sure of.. The max width a tire can be without rub when turning for the stock wheels is 10.5in or even a little less then that..

There is a thread that goes into detail what tire sizes work with a stock JK and it's wheels.. I will see if I can find it for you

So what youre telling me, is that the tire option I listed as won't fit an 18*9 wheels? ( that will not be stock rims)

XJ Knight 05-11-2012 04:16 PM

Oh no that was with the thought of the stock 18's in mind.. But the stock 18's are 18x7.5 and that sliped my mind.. The tire size you are looking at will work just fine for 18x9's as long as the back spacing on the wheels you have or are getting is between 3.75-4.5in.

What wheels do you have?

well currently everything is stock on the jeep. But I'm looking to purchase the wheel/tire combo this upcoming week.

I really wanted 18 inch wheels, so that's why I was asking if that size would fit my jeep.

I want to purchase the RBP 97r in black, they come in 18*9.

Just googled them.. Nice wheel!.. Just make sure that you get them with 3.75-4.5in back spacing.. and they will work great for you.. If your buying them through a site you will likely have to call them to find out what the back spacing is available for the wheel as alot of sites don't list the available back spacing with the wheel on their site

XJ Knight is right on. With an 18x9 wheel a 3.75-4.5" backspace would be ideal for your jeep. You shouldn't have any rubbing with a 275/70R18 but there's a very small chance that you could get a very little bit of rubbing in the front when you are turning the wheel to the full stops left and right.

Are you planning on lifting or leveling it out?

And if that does happen, it's REALLY easy to fix. Just add some washers to your steering stops.

I'm not kidding, a talented chipmunk could do it. Here's a step-by-step:
