I really enjoyed knowing Chris, the owner of the Big-O in El Dorado Hills, for one of several reasons...he and his crew had no issues mounting various tire/rim combos for me.

Try some other tire shops:
Allen's Tire

Yahoo search for Reno tire shops

I would definitely call around. A mom & pop may be your friend.

Regarding things to check...normal stuff like ball joints, tie rod ends, idler arm, control arm bushings, etc. Whatever tires you choose, front end alignment is good insurance for a street driven vehicle.
