I put a set of these Pirelli's on my Blackbird days before embarking on a trip down the West Coast leaving from Alberta, hitting San Francisco and back up through Reno. The other guys on the trip thought I was crazy for running these tires for extended highway driving but they held up very well. In eight days I put on approximately 6000 km's and they show no more wear than the guys on the VFR's running Bridgestones, and at times I wasn't being gentle with them!
