Re: Which wheel size would be better??

It is pretty much personal preference. Either wheel will work, the 15x8's will just have a little more sidewall bulge which helps protect the rim. I don't know of any reason why one would be better than the other. I run 15x8's with a 11.50 wide tire and I am going to run 15x8.5 with a 12.5 inch tire..don't know if I will see any difference. Hope this helps(probably not but oh well)

The narrower rim will help prevent rubbing, as well as aid in keeping the bead seated when you air down. I would definately recommend the 15x8.

What do you use your jeep for ?
For Offroad the 15x8 would provide a little more sidewall bulge that protects the rim better,but on road the 15x10 seams to provide a better cotact area and will wear better.the 15x10 will also be slightly wider

<font color=blue> I have 31 x 10.50's on 15x8 rims. My friend has 33x 12.5's on 10 inch rims, besides the fact that they look MUCH larger, he experiences better "float" on sand... where I tend to "sink" in...

I have two sets of 33's, one on 15x8's and one on 15x10's. The wider set rubs my fender flares and they are a real bi%ch to reseat the bead once they pop off. I haven't noticed any real differences other than that. They both ride about the same and I haven't noticed a lot of difference in wear, but my Jeep only sees about 1000 pavement miles a year.

If you use your Jeep off-road, go with the 15x8. 15x10's don't hold a bead well, once you air down.

Re: Which wheel size would be better??

Three things to consider.
1) Off road. 8's will air down further and stay on the rim better. I run 6 to 8 psi on 35x12.5 BFG AT's on the trail (8" wheels). A little mud, dirt, sticks and rocks works their way in between the tire and rim, but seldom blow a bead completely. I would give the 8's a grade of 95 and the 10's down in the 60's or 70's for staying on the rim, maybe even a little lower than that. Also the bulge created by the 8's tend to protect the rim a bit more, but the truth is that when you drop the psi real low, the sidewalls move sideways pretty easy and protection for the rim is just marginally better. I run cheap steel wheels and replace them one at a time when necessary - usually 2 or 3 a year.
2) Highway. 8's bulge out more and thus cause the tread to be more rounded instead of flat on the pavement. Grades: 8's maybe an 80 and the 10's in the 90's for flatness of tread on the pavement and maybe a little bit more stability because you can air the 10's up a little bit more and still have a flatter tread line.
3) Looks. Totally opinion, but the 10's look much better unless bulgey, donuty looking tires and wheels are your thing.
As far as I am concerned am much more concerned about off road usefullness, the highway manners are close enough to not matter that much, and I couldn't care less about how it looks, so I run 8" wheels.
