I am still running with the Durano pluses I fitted to my road bike back in October 2012. They have been excellent with only the one visit from a certain fairy and hawthorns go through most tyres. They are heavier and slower rolling, but they grip exceptionally well and I am happy to use them in all weather conditions including ice - but I have plenty of experience of cycling on ice. The only time I didn't use them last year (2013) was when there was 6 inches of snow of the ground at which point I went over to studded tyres on my mtb... I've done around 4,000 miles on the Durano Pluses so far.
