To all the volvo 2011 c30 R-DESIGN PROUD OWNERS. Be warnedBout these tires. I love my volvo sports coupe, but i hate these pirelli tires. Bought my volvo c30 used at 11,800 mikes. the cupping noise is irritating and unbearable. i had volvo inspect the car and they said the pirelli low profiles are known to make a sound if the wear is uneven. The tires are practically 6k mikes used and are fairly new. I had them rotate the FRONT TIRES TO THE REAR. The was worse. Im now shopping for new tires.
