Stock tires on aftermarket rims

I am looking at a set of kmc xd798 addicts in 17 inch and am wondering if I can mount my stock rubicon tires on these wheels. They are 9" wide which is what raises a concern for me and I want to make sure it is possible before I order anything. I still have a good bit of wear left on the tires which is why I am looking into this. Any help or advice is greatly appreciated.

I think the stock Rubicon wheel is 7.5" width with fairly deep 6" backspacing.

If I'm doing the math right a 9" wide rim with I'm guessing 3.75" backspacing (19mm) pushes the exterior rim lip out 3" further than your current wheel. Might stick out from your fenders.

Stock BFG MT tires will fit the wheels of course but shallow backspacing and exposed rim lip might not be the best set up for wheeling. Risk wheel damage.

A 12.5" wide 33 or 35" (295/75 to 315/75) tire would be a good fit for those wheels.

The biggest reason we like to run 12.5" wide tires on 8" wide wheels is that when you air down there is plenty of side wall pressure holding your bead. If you're staying on road at normal tire pressure, you should be ok. If you want to air down off road, I'd look for a narrower wheel or get wider Tires. If your tires have tread on them, you might be able to sell them with the stock wheels and recoup a lot of the cost of you new set up.

What is the backspacing of the wheels you're looking at? If it's too much you can always add Wheel Spacers, but you'd want to know ahead of time.

Let me know if you have any questions or would like a quote on anything.

Stock Rubicon tires sized is 255/75/R17. The recommended wheel width for these tires is 6.5-8.5"

I haven level 8 rim on my Rubicon. They are 8.5" wide.

Hi mikeJKUR,

Do you have more of a straight on view that shows the tire and rim width better?

Thanks,

Thanks for the pic. What is the backspace on those rims?
