If money is not an issue then blindly go ahead with the XM2 as they offer an amazing ride quality. You'll notice the difference immediately. I changed from JK Tornadoes on Alto K10 to Michelin XM2s and the ride is just awesome with amazing grip levels. Cornering at high speeds is not a problem with the Michelins unline Jk tyres which would squeal.

You do get what you pay for!
