The initial impressions have only been good. like putting in soundproofing. Where did Amtel Cruise's continual buzz go? He has vanished. The vehicle rolls and stops superbly. My Duster's tires are excellent. Added on September 25, 2017. Over 500 miles were skated in three days. Remaining pleased with the tires. It still makes noise, but considerably less so than it did with Amtel. Subjectively, the Wiatti is just as noisy at 120 km/h as the Amtel is at 100 km/h. In Amtel, the stability of the exchange rate is generally unmatched.
