This tire is QUIET! I had Avid Envigor s on my Z3 and loved them so I knew what to expect. I got that and more. Wet and dry handling inspires confidence but comport and low noise level makes listening to the radio a joy. If the UTQG rating of 740 A A is close to true (Thanks to Orange Oil) these tires will be up there with the world's best. I totally wore out the OEM Continental Run Flats in 42,000 mi (not bad for a tire I otherwise hated! The Yokos are not run flat but I bought a Slime kit with the high capacity pump and a AAA membership. I feel protected and would NEVER change a tire on the roadside. P.S. Tire Rack Customer Service and NTB installation are GREAT!
