So my Dunlop Roadsmart IVs arrived today. Thank you Long Ranger for sharing the info on the free front tire promotion. The bike currently has Michelin Road Pilot IVs. A couple years ago I replaced the rear tire because of a nail puncture. Now, the front tire is worn but the rear tire still has life left in it. What are your thoughts on mismatched tires (replacing the front with the new Dunlop and leaving the rear Michelin on until it’s done)? If I replace the rear now, is it possible to remove it without damage and keep it as a spare? Your thoughts are appreciated. Thanks!
