They do seem quieter than the Hankooks. The car had also developed a slight pull to the right that was also remedied. They were about $9 more per tire, but recommended for Lux autos. (Mercs, BMWs, Lexus, etc.) This is the first time I actually had trouble finding any information about replacing tires for my autos. Think I might have been the first.
Really? Hmmm...I need a new tire ASAP for my Cadenza. Has 2 bubbles and a nail :/. A quick can of fix a flat fixed the loss of air problem. I really wish that the car displayed the air pressure rather than just telling me what tire is low.
