Help! Any good tire shops in Vegas?

[JayR]

So, Bill, Yancy, Brian, Shafi and the guys made it all the way to Vegas driving their show cars and went to Big O in Vegas to have Brian's race tires switched onto his wheels and they damaged his wheels to the point that they didn't trust these turkeys to switch the rest of them and Shafi also needs to switch out tomorrow before set-up at the show so they need a reputable tire shop who knows how to treat nice wheels and is open on a Sunday. Any suggestions is much appreciated!

Imagine driving all that way only to have your only damage occur at a tire shop at your destination?? WTF??
