SH, interesting about Discount Tire. There are two locations here in Yuma, AZ. The location on 32nd ST., forget getting my 40' fiver in there. Their newest location at the Palms Mall is good to go. I have had Michelin XPS Ribs mounted on our fiver at Discount at one of their locations in Henderson, NV. Don't recommend that location as the best way is to get there about 7 AM, back in, then after mounting, pull out. It is on a busy Frontage RD. I did find another location in Henderson and had a set of Ribs mounted there last spring and they have all sorts of room. They were building another location not to far away and you will be lucky to get a Kia in there. My only problem with Discount has been some of the tire mounters don't know about stagger in dually valve stems.
