These Driveguard tires are great! I had the OEM Bridgestone
Potenza runflats on my 2009 3-series with sports package. The
Potenzas were loud, rough riding, and falling apart after 28,000
miles. After reading the reviews I ordered the Driveguards as a
replacement and they have been nothing short of amazing. They are
quieter, ride smoother, and don't give up...
