I don't know of anything in Tucson but I will recommend treadwright.com.
They have somewhat limited sizes but the quality is incredible and the price is absolutely unreal.. You can read tons of positive reviews over on Jeep forum. Mine are wearing like iron, still soft and grippy. The snow traction (not like that is a concern of yours) is amazing, better in 2wd than my old BFG a/t in 4x.. I run them on my CJ DD, put an easy 8k on them so far..
Even with the cost of shipping and local mounting fees you can't beat them with anything else, not even close..
