Add me to the list of people who HATE the OEM Michelins for lack of wet/dry traction and poor handling. I replaced mine with Vredestein Quatrac 5's, bought a portable compressor, plug kit, and can of sealer, and never looked back. The Vredesteins are low rolling resistance, "Y" speed rated (186 mph), and noticed no significant difference in range. In driving, however, they are day and night better for handling and stopping. I have these tires on 2 other cars (a 2002 WRX wagon, and a 2012 Toyota Highlander AWD). I did note that each tire is different (WRX tires were made in Hungary, and are V rated, and the Highlander tires are made in Denmark, like those on the Bolt, but also with a lower speed rating, but still at a level that is imaginary for the Bolt). While the speed rating is superfluous for the Bolt, it reflects a higher quality tire construction. I consider these some of the best tires I have owned. They receive good reviews from Tire Rack and Consumer Reports, among others, and are considered among the best all season tires for snow too.
