Hi, I've posted this question in General Discussion and was told that it could be best to move it here (I forgot there was a dedicated wheel/tire section). So here it is!


I am currently running on my 2014 JK stock 17 inch wheels and tires (255/75r17) and I am looking to buy steel wheels for my future winter tires (I want a set of dedicated tire for winter) and I am hesitating between 17 and 16 inch wheels.

In the exact same tire size as I am currently running, the choice is very very limited, so I am looking at other sizes that will keep the same diameter. I looked into 265/70/r17 (half an inch of difference in diameter) and there are quite a few more options available.

I also looked at 265/75r16 (half an inch of difference too) and there are way more options.

So my question is, with only half an inch in diameter difference between my current tires and both the 265/70r17 and 265/75r16, can I make the switch easily without having to change anything with a ProCal? Also, having 265 as the tire diameter and currently running 255, is the difference big enough that will require spacer wheels or it should be ok (assuming same backspacing on the steel wheels as on my current stock wheels)?

Thanks!

Your stock Goodyear's have 649 revs/mile which means a height of 31.07 inches. Most 265/75/16's run 654 revs per mile. I bought Yokohama AT's in that size which have 647 revs/mile making them slightly taller. Other options are 275/70/17's which are basically the same height as the stock tires.

With only 1/2" diameter you don't need to make a change with a Pro cal but it wouldn't hurt to update it. Either tire size will work with a wheel with the same or less backspacing as your stock wheel. If you decide to go with an aftermarket wheel just make sure your tires are approved for the width of the aftermarket wheel you are considering. (tire manufacturer's list recommended rim widths for each tire size they sell on their spec sheets). You can also call us at 1.888.459.4080 and we'll be happy to recommend tire and wheel sizes that will fit your needs.
