I've been using the same tire shop for many years now, since they've always had the lowest prices in town, but out of curiosity this afternoon I phoned another tire shop that is close to my house. I was going to give them a try since their website looks pretty good and they boast to be high performance specialists. I know they sponsor a lot of racers too. So I phoned them up for a quote on Pirelli P Zero Neros for my Corvette. They quoted me $502 each, for 275-40-18s. I then phoned my trusty old tire shop that I've used for many years, and their price was $336 per tire! So it definitely pays to shop around when looking for new tires, since there can be a huge difference in price from one shop to the next. Although in my case there is no point to phone around since if I just stick to my original shop I know they're going to have the best price, or within a few dollars of the best price anyhow. It's amazing how some shops think they can sell the same tire for such a vastly different price! I'm sure a lot of people fall victim to this sort of price gouging too.
