It is ALWAYS wise( I think), to get your tires/service done at a NATIONWIDE chain. From my experience, I strongly advise "Discount Tire.inc". Very competitive prices .......and MOST importantly....they know HOW to fix large tires. Yeah,Walmart and Costco can (sometimes?) save you a few bucks....but IF you have a serious tire-issue 15 miles outside of ,say, denver.....they DO NOT have a service truck. Places that sell cabbage are not to be considered "professionals" in the tire industry. Im not saying that they are "lame"....but Id much rather have a specialist take care of this item! As a retired Airline Mechanic/Inspector, the VALUE of experience/specialization is HIGH on my list. Just for giggles, I performed a search and found that the following cities have a Discount Tire,inc store....Minneapolis,Denver,Baton Rouge,la.,San Antonio,Portland ore,Cheyenne wy,Baltimore md.,Norfolk va.,Omaho ne.Memphis tn....and dozens of others!!!! My personal caveat is that I'd drive on a flat before stopping in Baltimore,or Memphis!!!! Just kidding!!(sort of).BOTTOM LINE...it is rather unlikely that you would be too far away from a Discount tire inc. store.I live in the Northwest, and a REGIONAL chain(Les Schwab Tire) is king up here....Superb Co, and very good people-highly professional-however they cover about 6-7 states. Wont do me much good in Texas or Illinois. On NATIONAL companies, like Discount Tire inc....their internal database can verify purchase, warranties,etc. This fact makes certain issues solveable from an internal standpoint.Just my .02 cents worth.
