I buy all of my tires at Discount Tire and my recent experience here just reminded me why. I noticed on Saturday morning that I had a nail stuck in the sidewall of my tire and decided that before waking up on Monday morning with a flat I'd better get it taken care of right away. Because the nail was in the sidewall, the tire had to be replaced, not repaired. However, because I always purchase the replacement certificates with my tires, it only cost me $20 for a brand new Pirelli tire. As always at Discount Tire, service was outstanding and my tire was done and car ready within 45 minutes. \n\nDiscount Tire, I am a lifelong customer!
