Tire Wear

[Bill]

Hi, My 2003 . ST1300 Rear tire wares on Right hand side, the rest of the tire is as new, so annoying. Anyone have a reason ?
Regards
Bill

Welcome to the forum.

Yes, for the same reason ours wear on the left side in the US: road crown.

Thanks for that, I had heard that but my others bikes down have that problem, A weight thing I suppose. Cheers for replying Bill

And the sides of dual compound tire tread are softer than the center tread. So wear is less noticeable on none dual compound tires. So there are two issues at play, which side of the road you ride on and what type of tire you use.

Which side of the road ridden on makes some small difference but the major factor to unsymmetrical tire wear is the different length of radius of turns on the opposing sides of the road. Right side of the road riders spend more time leaned into left handers so tires typically wear faster on the left side of the tread.

Look at the chicken strips and note that gradient of crown is at most 3-4% (2% is standard in the USA) but unsymmetrical tire wear extends out to the edge of the tire - at lean angles up to 50 degrees or more.

Corner harder on other side eh?

It's those dang roundabouts. If you had stoplights, your tires would last longer (but you would burn more gas idling).
