Title: Uneven tyre wear
Post by: quixoticgeek on 19 September, 2019, 05:03:17 pm

I'm noticing that the right hand side of the tyres on my Brompton seems to wear faster than the left side. Especially on the rear wheel. It's happened with both a marathon plus, and a normal marathon tyre.

Any ideas what would be causing this? The current rear tyre has had about a roughly 50:50 usage cycling on both the correct side of the road, and the right side of the road.

Possibly a misalignment of the frame or you might be riding with the bike leaning e.g. if you have one pannier or uneven loading of panniers?

No panniers...

I saw a photo from a cyclist in Australia showing the same thing. Apparently it's because of the road camber, for drainage purposes.  Can't find it now though.

I tend to lean the bike slightly to one side when I'm riding, judging by my default view of the front wheel.  Presumably because my body's a bit wonky.  I think this is a bigger factor than camber or luggage distribution.

In NL, the road camber would bias wear to the left side of the tyre (though I expect most cyclepaths have no regular camber).

The answer is probably to turn the tyre(s) round occasionally
