Hi, I have been running mine on a 185/70/14 Nexen, they have have been across europe twice with four adults and luggage for both Le Mans Classic and Spa Classic, are showing very little wear after approx 5,000 miles and give just a little more wheel arch clearance. The sat nav speed shows very similar to the speedo at 70 mph are so I'm not too worried about that either. Regards Andy
