I've had problems with a company-owned Firestone store. One Sunday manager told me I could get a buy one get one free deal extended if I just brought my car in on a Monday when they could order the tires. He gave me the name of the asst manager to talk to and everything. I show up that Monday and the asst manager tells me I could only get that deal if I prepaid for them them that previous weekend (which I offered to do, but was assured was unnecessary). However - I will say that nobody at that shop ever recommended a service that wasn't necessary (I've bought "lifetime" alignments there). About all they've ever recommended was new tires when mine obviously needed replacement. However - recommending Bridgestone Potenza RE92s? Not even.
I ended up going to an indie tire shop that charged about the same price with free rotations. I don't know of many retailers that don't offer rotations every 5K miles for their customers.
As hinted before, I didn't care much for the RE92, which is used for way too many OEM applications. Most hate them. I've never had any serious problems, other than the RE92 sucks for many of the high-performance cars it comes on. They squeal like you wouldn't believe in mildly hard cornering.
I already mentioned this, but the BF Goodrich tires brand name was bought out by Michelin in the late 80's. Dunlop Tire (tyre if you're big on their British roots) is now a joint venture between Goodyear and Sumitomo Tire.
