Tuesday I plan on heading down to sears to pick up some tires on my sears card..I want to keep the stock 18" rims on my sahara, but am wondering if i go with a slightly larger tire if I need to take any other steps other than just having them put them on..instead of the stock 255 70/18's i was thinking about the goodyear duratracs in a 275 70/18. With a tire that's slightly bigger am i going to be rubbing too much to cause concern? or i should i add the washers to the steer stops or spacers to stick the wheels out a bit? or should i just let sears do their thing and install them and drive. i don't do any wheeling yet, just a DD but we get a lot of shitty winter storms up here, and the bridgestone duelers were god awful in the last one in even a little bit of snow..thanks guys

 

and also would i need to change anything with the computer because of size difference? or will it not matter so much since it'd be a small change

 

I would guess that you will have to space something or stop something. I say this based only from the fact that my STOCK X and STOCK wheels and tires rubbed at full turn when not on level ground. They only hit the sway bar and it was minor, but they did rub. If you do not wheel it, you should be fine though. Mine only rubbed when twisted up and I had the front disconnected.

should not have to change anything in the puter unless you want the speedo to be correct, I doubt it would be noticable anyway, maybe 1-2 mph.

 

You will more then likley need wheel spacers to prevent any kind of rubbing

 

Don't base the need off of someone else's build, get them see what, if anything, rubs.

-If the tires rub when flexing, add bumpstops or a small lift or chop your flares.

-If they rub somewhere inside the wheel well, change the steer stops or add wheel spacers or get new rims with less backspace.

You have options.

There isn't a huge difference between those tire heights. A ProCal or Flashpaq would be nice for recalibrating (and for all of the added functionality, of course) but not really needed.

 

Agreed....

 

thanks guys!

 

That tire is only 1" in dia bigger, off road you might have minor rubbing. On the payment probably no issues unless fully locked when turning. There will be a +2 MPH at 60 MPH difference.

 

well after a day of having my tire guy call around to all sorts of companies for tires in the 275/70/18 size he finally came across some duratracs for me, and on my birthday no less!!!! only downside (and its not so bad) is the only ones available at all, even after a direct call to goodyear, were 275/65/18's. no big deal. can't wait for the snow storms to start rolling in again! they look great and they GRAZE the swaybar ever so slightly at full lock but not enough to bother anything. they look great and FOR NOW, emphasis on FOR NOW because im sure i'll get a lift..these tires will serve me well!

 

please post some pics!! I am looking to do the same for my jk.
