Discount Tire just lost my business
I'll continue Charlie's rant, though Discount Tire (was America's Tire here) has always done me right. In my case, Goodyear in Atlanta spun a stud on my 69 Dart and didn't tell me, just re-installed the wheel like that. I found out when the tread separated on the highway and I couldn't take the wheel off, so had to drive home with the tread slapping the inner fender. I am guessing they didn't understand left-hand threads, strange since many cars had them in the 60-70's (Charlie's Saab?). After that, I always had the tire service guy (never a Goodyear again) write "LEFT-HAND THREADS ON LEFT SIDE" on the service form, and still had to step in the shop and tell the illiterate idiot to stop cranking up his impact wrench when I saw him fussing with a wheel. Even with all my diligence, a Pep Boys managed to put a big scratch down the side of my brand new paint job, then claimed they had no tool that could have done that, so I have shunned all Pep Boys since. Tires are the only thing I have a shop do, and I usually take them off and bring them in so they can't screw up my cars.
BTW, tread doesn't come off only on old tires. All 4 Uniroyals that GM selected for my new 82 Chevy S-10 had tread fly off in big chunks before 20,000 miles. I wonder why they went out of business.
