As for looks that is pretty much a personal thing, I wheel my rigs and think that anything under 13.50s on 10 inch wide looks like mall crawlers not trail machines.

If I was in his position, I would just buy the 15x10 wheels and run them with stretched tires until I got the new tires. It may not be the best option "right now" but it will be benificial in the long run.

Besides being unsafe for him, if he is driving on public roads, it is a danger for everyone else on the roads. At least if he is running an eight inch rim it isn't that much over the recommended size that it would be unsafe.
Mostly though he will be able to air down and use his Cherokee to go wheeling.

Taller tires are harder for the engine to turn but this can be compensated for by changing gear ratios. Lots of reading available and good info out there......problem is, there's just about as much BS also.

C'mon guys, the OP's young, got his 1st car, it's his DD and it's an XJ. How 'bout a little LESS chest pounding/muscle flexing and get him started in the right direction. He's asked some good questions about wheels/tires for his DD, not how to convert it to full tube frame competition rock crawler running 5 psi in beadlocks.

All of the mfgs show "measured rim width" on 10" wide rim in their "specs" chart with a minimum rim width of 8.5". Any goober with a tire machine can put a 12.50 tire on a 4" wide rim but MOST MFGS DON"T RECOMMEND IT................FOOL.
