The impulse to soundproof the cabin has entirely vanished since the purchase and installation on the VW Polo Sedan. 195/55/R15 worth of Czech Republic output was purchased. Amazing driving experience—just get high—she rides so softly! The wheels always appear to get caught in the pavement even with hard braking, unlike the basic tires that Volkswagen ships with. The ABS has never worked. I started moving rails and potholes with caution after reading forum remarks regarding the poor walls. I can't speak for myself at this time, and I hope I won't say anything more.
