Modern Vespa

The front tire on the SS is wearing on the left side. I wore a tire almost to a point on the Motovespa once ( not a whole lot of straight roads around here) but this is odd.
I put a long straight edge against the sides of both tires and they line up perfectly. I used one of those digital angle things with a short straight edge against the rims top and bottom and they are off by .6 degrees.
I know these bikes lean a bit to the left to balance but I can't see that as the cause. I feel no issues with handling or steering. Inflation is by the book.

Seen this many times. Guessing it's normal, so I ignore it.

Although marked, I doubt these Pirellis are really directional. The tread certainly isn't. I think I'll just turn it around and work on the other side.

if you want a a bike that rides funny and has unpredictable shitty handling that's a real quick way to get there. please don't do that.

I'm guessing that you have crowned roads where you live. that in conjunction with the inherent "vespa lean" causes wear like that. especially when logging straight miles.

buy a new tire and tube for the back, rotate that to the front. or go to a three tire rotation to get the most miles out of them.

OK. I probably wasn't going to do that anyway.
The crown on the roads could certainly be a factor but I haven't worn front tires like this on any other bike.
