Looks or not I wouldn't go for a 10" wide wheel for tires with an advertised 12.5"width for a Jeep that goes offroad with aired down tires. The wider the wheel the more air pressure it takes to keep the tire beads seated on the wheel. Conversely the lower the pressure you can air down to safely with the narrower 8" width.
For street use only? Or very easy trails where airing down much isn't needed? A 10" wheel is fine.
