My five year old Bridgestone 255/60R17 Dueler H/L Alenzas (65,000) are beginning to dry rot. Started shopping for a new set of the same tires (even with the dry rot problem these tires are hard to beat). Was going to go the Tire Rack route when I got a $100 coupon ($70 on the tires + $30 on the installation) for Bridgestone tires at Costco. The Costco price was competitive before the coupon - after the coupon it was unbeatable. Installed with NJ sales tax and fees and nitrogen inflation (no extra charge) the four tires came to $732.00. The Bridgestone sale was also posted at the tire center so you may not need the coupon but you do need to be a member.
