Keeping JKUR stock tires on 9 inch wide rims: Good/Bad

I'm getting my new JKUR in less than a month. I'm trying to save some money until I finally can get the whole package (lift and 35s) so I was planning on getting the Rugged Ridge Satin blacks for now that are 17 x9 and putting the stock rubi tires on them. The tire specs say up to 8.5 wide rims. I really don't want to spend extra on tires since I'm not getting the lift yet but I hear some negatives out there including the below from the manufacturer.

You mentioned in your email that you would like to install the BFGoodrich Mud-Terrain T/A KM tires on a 9" inch rim. We would not recommend that you install size LT255/75R17 on a 9" rim. This could be a safety issue. Also, your tires could possible start slipping on the wheel, causing irregular wear, or other problems.

If you kind folks who have experience this set up can give me some positive feedback it would save me some time and money.

Oh and I really want to put the new rims on as soon as I get the jeep so keeping the stock rims are not a preferred option.

How did this work out for you?

I'm thinking of putting 255/75-17 tires on a 9" rim as well (Rugged Ridge).

Thanks! As far as ride quality, performance, and fuel economy, do you think there's a big difference between going with Rubi tires vs. 285/70-17's?

No lift yet and those are ~33" tires, which is about the biggest that will fit without rubbing.

The wheels I'm interested in have 4.75" of backspacing.

Oh I have no idea I wouldn't think so but I'm not sure if it's a 2012 probably not. And about the rims id say go less on back spacing if your gonna get a lift cause the rims I wanted before where 4.75 and wouldn't work with the lift I bought so I got 4.5 backspace.

My buddy and I got rubi just a couple weeks apart. The only difference between his and mine are the color and transmission. He has auto and I have manual. His is completely stock and I put on the 285s with 9 inch rims. I asked what his mpg was and he said around 14 and mine is around the same too. We both live in the same neighborhood on a hill and we commute via freeway so we basically have the same driving habits. So I dont think mpg is affected much by the slight change.

I have the same rims that you want and I put them on 285/70-17 goodyear duratracs with no lift. See pics for look.

Any other opinions on this? I'm looking at picking up the Rugged Ridge 17x9 wheels and just putting them on the stock Rubi 255/75/17s for now.

Thanks!

Just checking: you put 255/75R/17s on 17x9 rims? I am considering the same but have not heard if it can actually be done,

Thanks!
