33x12.5 duratrac on 8" or 10"

Looking at 33x12.5x15 Duratrac's for my son's DD
Specs say min wheel width 8.5"
Should I go with a 8" for rim protection or 10 "
Pro's and Con's

Thanks

8 inch is best for offroading. It holds the bead better, but might cause the middle of the tire to wear faster than the rest of the tire if you run too high of air pressure on the road. It will also make your mpg go down. 10 inch is best if your jeep is on the road constantly because it would allow you to run a higher air pressure and not having to worry about the tire wearing irregularly. It would also give you better mpg.

i have 31" 10.5" duratracs on an 8" rim. im running 30psi front and rear have done the chalk test and it seems to be the perfect pressure for contact. im getting about 18mpg (after correcting for the change in tire size) on the highway. I dd my xj and the road manners are pretty good. IMO it all comes down to what the jeep will be primarily used for... i like the protection the narrower rim provides especially if you rub a curb.

I've have kind of the same issue, I currently run a BFG mud terrain 31x10.5 on a 8 inch wheel but I also have a set of 33x12.5 BFG all terrain that I want to run for the summer and I don't know if I should switch to a 10 inch wheel or keep the same width.

I run a 33x12.50 on an 8" wheel. It airs down nicely and I have never had any issues.
