Im 700km in to my 3rd rear night dragon and first front one. I'm getting between 6,000 and 7,000km out of rears. Great tire though, they hang in well wet and dry. When the rear runs out of grip it a smooth controled drift. I love them they are magic.
Pulled the Night Dragons off mid Febuary. 10,000 on the front 21", 6,500 on the rear 180 x17". They had a little bit left but I was going on 3,500km run and they wouldn't make the distance and would have been haiey in the rain. The rear was starting to chew the edges of the tread and the traed disapeared real quick in the last 1000 kms. This is on a basickly stock 88" Wide Glide.
