This was a personal best for me! This was about 2 weeks after I got my new Kumho Solus kr21 tires installed. I was doing a 7 car caravan (I was the only BMW) to South Hampton, Long Island and we averaged about 60-65 mph to make sure everyone was kept in check. I was the lead car. I reset the miles right after I filled up for the trip to South Hampton. Can't believe that I got 169.4 miles on a quarter tank of gas with a 4.4i!
