A follow-up to my 1/26/02 post. Tire Rack says all four tires are manufactured the same, Dunlop says all four tires are manufactured the same, but this is the description of the tire (copied directly from Tire Rack):
>On the outside, the SP Sport A2 molds an innovative dual-phase tread compound >into a mildly asymmetric tread design that features outside shoulder blocks >with minimal siping to enhance steering response and cornering stability while >the inside shoulder blocks feature more sipes to provide the additional biting >edges to aid traction in foul weather. The SP Sport A2 radial’s 3-rib center >contact patch is designed to enhance dry, wet and light snow traction during >acceleration, braking and cornering. The entire tread design features >Dunlop’s “CHAOS” pitch sequencing of tread block shapes and sizes to help >reduce noise to increase comfort. On the inside, the SP Sport A2 features >twin, high-density steel belts reinforced by Dunlop’s JointLess Band nylon to >enhance driving control and provide long, even treadwear while minimizing >weight and enhancing ride quality. Additionally, hard rubber bead fillers and >a high ply turn-up enhance steering response and cornering stability."
After reading this it seems that there should be a "left side" and "right side" tire since the tire has "a mildly asymmetric tread design". However, I finally had to take a digital picture of the tire (please don't make fun of me for this - I'm a commercial banker not an engineer!) and rotate it 180 degrees to see what would happen. The tread compound pattern would be the same if you switched a tire from the left side of the car to the right since you would turn it 180 degrees.
OK, I feel much better now. Thanks to all those who helped!
