What size Avon did they put on when the tire was changed?



Stock size 170/80 15.

Looks like my rim measures out the same as Bixer10's.

In my fits of measuring, one oddity I did find was that when I laid the straight edge across the outside edges of the tire, then measured to the rim...the tire is "wider" towards the drive side 6mm. I know that makes little sense but I triple checked it in several places.

I know of several ways to prevent the tire from hitting the fender, but I fear I am going to mask an issue. The thing that really gets me is that the bike rides fine.

look at these pics dropping the straight edge from the inside of the frame rails. You can see where the tire has been hitting.

Thanks for the continued help on this!
