You are a serious road warrior!
I'm thinking I might be around 3500 miles on my Radrover(s) when my 1 year comes up in September. My mileage is a little different because I'm splitting the road time between his and her Radrovers (around 1200 miles apiece now). The wife only put around 100 miles so far out of 1200. I just use both for work commuting and switch off to keep the wear/tear/mileage around the same. Replacing the Kenda tires with Vee Rubber Vee8 was the only non-warranty thing I did so far.
