I purchased a set of these tires to replace my Dunlop's back in 2008. So far I have put about 75k miles on these with all types of driving conditions (city, highway, off-road, snow, rain, ice etc.)with great results. After 75k miles I still have a little bit of tread left. However, a slight suspension alignment problem has caused some uneven tire wear so I am going to replace them this winter. My overall opinion of these tires is positive. The only negative is that they produce a tiny bit more road noise than a regular tire would. However, this is due to the fact that they are an all terrain tire with pretty aggressive tread.
