I am buying tires for my Camry and seen at the local tire shop 70,000-80,000 mile warranty tires. I assume the higher the treadwear number on the sidewall of a tire the harder the tire. The tires will last alot longer but compromise great traction. how good/bad will the ride and road noise be? could they compromise handling too much. any info would be great! thanx scott ------------------ Bolt ON is there such a thing?
