How in the world do these guys stay in business? I took advantage of their free brake check service on my 2001 Explorer. My front tires were a bit worn, but within spec (easily). They said brakes were fine, but I needed 2 new front tires, and they just happened to have a quote. For 2 off brand 245-70-16 tires they quoted me $435 and change and a second choice for about $475. There was no one else in the store the hour I was there. With those prices and the off brands that they sell, again, how do they stay in business?
