Strange tyre wear pattern... - SV650.org

22-12-06, 12:07 PM

Noticed my front tyre is very worn on the right hand side but not the left. It's a BT020 tyre and about 2mm from the center groove has gone bald but the other side has plenty of tread left. I do about 70 miles per day and have done 9'000 miles now. Could my forks be out of alignment? It doesn't feel off but I've been riding the bike for 6 months so I might have gotten used to it.

Yeah cheers!

Well I thought that at first but it is literally just a few mm from the centre groove.

That's normal as we drive on the left.Road camber wears that side of the tyre slightly more,and we tend to be more enthusiastic on right hand bends like roundabouts.

BTW it needs changing as it will have naff all grip left.

I agree about the wear, but I really do wonder just how much camber contributes. Camber isn't generally very great out our. But having said that, if you're positioning for view on bends, you'll be riding where the camber's greatest on RH and least on LH bends. I've also read a technical-ish article that suggests that the distance travelled through right-hand bends is much greather than for left-handers. Countries where they ride on the right experience wear on the left of the front tyre instead. I wonder if the subconcious counter-steering contributes too?

I can see I'll awake all night pondering this one again.

They all do that sir ! I've always blamed roundabouts, never thought about the camber effect before, you may have something there Biker Biggles.

9K on a front tyre

I'd be luck to get 7K from mine. Thats a bit of a difference though. If the forks are out, the bike will pull to one side.

it's cause you blokes ride on the left side of the road instead of the right

here in america where we ride on the right side of the road, our tires were on te left.

it's cause on outside radius of corners you travel further ans get more lean time on outside radii

Several different theories as to why this happens,but all agree it does.Either way you are well overdue a new tyre.

the only reason i ever change the front tyre is cos of this! its cos the right had bends outnumber the left!
