Can anyone shed some light ont this? The front tire on my 85 VN700 is a Dunlop Qualifier like came on it origionally. Its the 3rd one and Id prefer to stick with it as I like the white letters. Anyway the tread is like an "older" style tire with 7 tread "rows" across the width of the tire. The question is the very center row of tread is nice and smooth albeit a little worn. BUT the tread rows on either side of center have a really bad heel-toe wear pattern to the individual blocks of tread. Is there such thing as bike alignment (I don't see how!)? Is it a tire pressure problem - too high or low? The vibration is making my hands and wrists fall asleep after a while so its a little creepy.
