Just returned from doing 4550 mile trip on 2010 wing pulling trailer. Bike know has 8000 miles on original tires and about 1000 miles from home the bike developed a horable front end shake at low speed that semed to get better at high speed. Once home i noticed that the back tire was badly worn and scuffed mostly on left side and front had some wear. I run 41 psi in both front and rear. I also noticed that i have signs of fluid leaking from the left fork. Is this low mileage a result of the stock Dunlops or is this what I should expect for mileage when towing a trailer. Any thoughts on the head shake? Starting out through 1st and 2nd the handle bars almost get riped from my hands. Bike going to shop tomorow and thought i would through this out. Any feed back on tire choices wouldbe helpful.
