Mine also pulls left and wears tires more on the right- I figure because I am constantly turning slightly right to hold straight. This is slight and only noticeable if I let go of the bars.
All good ideas above that I plan to look into further. Here's another idea.....
I loosened up the lower fork yolks and pinch bolts, got on the bike, held the front brake and bounced the front end several times, then tightened everything back up. Still a slight pull, but better!
This guy is good.....
