CRM1988 Posted September 30, 2016 Share Posted September 30, 2016 What would I have to do to a stock MJ to be able to put on newer 17inch wheels? Not wanting to put much of a lift on it. Link to comment Share on other sites More sharing options...
Pete M Posted September 30, 2016 Share Posted September 30, 2016 need more info. 17" rims (assuming the are of the proper backspacing) won't affect anything with fitment. tire size is what does that. Link to comment Share on other sites More sharing options...

Zebvance Posted September 30, 2016 Share Posted September 30, 2016 2015 17 inch Rubicon wheels and tires you would need adapters, the bolt pattern are not the same. Link to comment Share on other sites More sharing options...
CRM1988 Posted October 1, 2016 Author Share Posted October 1, 2016 So would I have to lift it? Link to comment Share on other sites More sharing options...
yxmj Posted October 1, 2016 Share Posted October 1, 2016 If you had the right adapter...with a 17"rim as long as you mounted tires with a side wall 7" or under....you would not have to lift A 235/75/r17 would fit (if such a tire exists) Link to comment Share on other sites More sharing options...

yxmj Posted October 1, 2016 Share Posted October 1, 2016 Now to be accurate you would need to calculate the width of the spacer/adapter to the offset of that rim.....but these would fit in the wheel wheel without a lift. https://www.tirerack.com/tires/TireSearchResults.jsp?zip-code=&width=235/&ratio=75&diameter=17&rearWidth=255/&rearRatio=40&rearDiameter=17 Link to comment Share on other sites More sharing options...
cruiser54 Posted October 1, 2016 Share Posted October 1, 2016 The 17s are a bit taller than a 31" Ain't gonna fit on stock height. Link to comment Share on other sites More sharing options...
yxmj Posted October 1, 2016 Share Posted October 1, 2016 Here is how you calculate the size of a tire... 235= the width of the tire in mm...convert that to inches and you get 9.25" 75 is the size of the side wall shown as a percentage of the width..176.25mm 0r 6.938 inches r17 is the rim or 17 inches so if you take the side wall height x 2 + the rim you get (6.93 x 2) + 17 or 30.86".....We will say 30 7/8" to round up. So smaller than 31 If you choose a tire that has a 70% or 65% profile ....or a narrower tread width you would have even more room . :MJ 1: .

HOrnbrod Posted October 1, 2016 Share Posted October 1, 2016 A 235/75/r17 tire is slightly over 30" tall. 30.3" on a couple I looked up. So 17's would fit with the right tire and offset it appears. Link to comment Share on other sites More sharing options...
shelbyluvv Posted October 1, 2016 Share Posted October 1, 2016 He has 2015 Rubicon wheels and TIRES. THEY ARE 255/75r17 in stock form. He will need at least 4.5" of lift and trimming to run them. Link to comment Share on other sites More sharing options...
HOrnbrod Posted October 1, 2016 Share Posted October 1, 2016 ...and TIRES. I MISSED that. Link to comment Share on other sites More sharing options...
gogmorgo Posted October 1, 2016 Share Posted October 1, 2016 255/75/17 works out to 32.5". 32 is the max diameter people keep quoting on here, with probable rubbing on lca's and fender liners at full steering lock. Given they'll be spaced out a bit, the fender liner rubbing will be worse. But I think 4.5" may be a little more lift than the absolute minimum necessary.

mikekaz1 Posted October 1, 2016 Share Posted October 1, 2016 3" would probably be the smallest lift you could do. And even then would probably rub slightly at full lock. Link to comment Share on other sites More sharing options...
cruiser54 Posted October 1, 2016 Share Posted October 1, 2016 3" would probably be the smallest lift you could do. And even then would probably rub slightly at full lock. This is exactly true. I know from firsthand experience. Link to comment Share on other sites More sharing options...
dasbulliwagen Posted October 9, 2016 Share Posted October 9, 2016 I have the standard JK wheels on mine right at 32" and get rubbing during certain turns but it isnt enough to damage the tires. I'm at about 1 1/2" over stock 2wd ride height. I'm not sure I'd have the same experience with the MT's you have though. Link to comment Share on other sites More sharing options...
shelbyluvv Posted October 9, 2016 Share Posted October 9, 2016 I don't see how, I have 265/75r16s on 4.5" of lift with trimming and they crush my fenders with the sway bar disconnected. If it is a street truck then it might be ok. If you plan to wheel it leave the sway bar connected.... Or your fenders will look like this.
