I never did either until I bought the Road Smart 3's. Previous tires on all my bikes from 600cc to 1854cc lasted between 3 and 5K. These new multi tread compound tires are the real deal. I also bought Michelin Commander 2's for my cruiser when I bought the Dunlops for the GSX. Both are dual compound and both are outperforming all my previous tires in both wear and grip. If you have only been running sport tires for traction you might be surprised at the grip the new sport touring tires deliver along with longer life and reduced warm up times.Wow, guys. I don’t get anything close to the mileage y’all are getting but I do ride with advance track riders on the street.
