You might save a little off your fuel bill by using these low rolling resistance XM2s. It's fine for city and highway drives, provided you don't take corners at above average speeds. If you drive like I do, which is to attack corners quite frequently, the sides of the XM2s will chip off and crack, bit by bit. These tires aren't made for cornering at fast speeds because of its soft sidewalls.

I read that low rolling resistance tires by Michelin that contains silica compound are likely to exhibit this tire chipping trait. Time to move away to a tire with stronger, stiffer sidewalls so that you can attack corners.

I've used 2 sets of XM2s and 1 set of XM1s. All had the same tire chipping problem.
