Hi,   I was wondering if anyone has purchased any of the new Michelin Road 5 tires?   I have the Michelin Road 4 on my bike at the moment. Extremely impressed with the wear and grip. Still got plenty of tread, but I'm looking at replacing them as I'm going on a long ride in the twisties (4,000kms) and want to make sure I have good tread for the whole trip.   I was going to purchase another set of Michelin Road 4's, but then saw that they have released new 5's - and
