Hello.
I have just noticed my front Bridgestone tyre has worn quite badly on the rh side. After only about 2k miles. This cannot be normal, surely.
At this rate. I'll be using 2 fronts to 1 rear.
Can anyone shed any light on this please.
Thanks in advance.
Regards. Sean.

Which bridgestone is it? Is it disc side or oposite?
-
Aye,
mines normally wears more on the left side, but as we drive on the right over here in Europe I've always put it down to the road camber.
-
Put it on centre stand, get wheels straight, get head down at floor level to look for alignment of front to rear wheels.
-
The tyre's are Bt45,s
The bike has twin disc conversion.
The wear is consistent with the road camber. But I would not have expected it to show so soon. I will check for wheel alignment. The bike rides well & true.
Thank you all for your inputs.
Sean.

I did read somewhere about wear on bt45's but cant remember where
-
For some strange reason Julie can wear out a front tyre before the rear but, it is always even wear across the tyre.
Are you sure that the right caliper is not pulling more that the left hand caliper and causing the uneven tyre ;)
-
It is possible that the brakes are not working evenly. As I have had a lot trouble with them. Squealing etc.
-
All the brake torque passes to wheel hub, then to spokes and onward to rim, makes no difference if one or t'other or both are working on a bike.
The application at tyre patch is identical whatever scenario.
They don't wear one side with a single disc either.

Had the wheels rebuilt at any time Arch?

Good point mate ;) I was thinking about a car wheel set up and one front tyre can wear differently to the other from brake binding .

Some Bridgestone tyres are well known for 'Cupping' on the rights side. It's partly to do with the road camber and tread pattern. Ignore it as it will last longer than you think.

Yes it's a bit thinky to get the force lines clear in your mind.
I've unusual input in that I've a Cannondale "Lefty" fork on a bicycle, one leg with disc and caliper with wheel fitted by centre bolt on rhs. As long as the tyre contact is bang in the centre of the frame it's absolutely neutral for steering and braking forces.
Quite funny though and draws odd comments when out on it. For enquiries I tell them it's really good but expensive and I'm saving up to buy the other side ;D

Don't forget roundabouts,
Those put a load on front tyres

I used to see quite a lot of this years ago caused by people who rode too far to the left of the road caused by the heavier camber.

if you were in Yorkshire I would suggest that the side you carry your wallet on might be heavier & wear out sooner, as it's never taken out.

True dat, Roo has a hernia on his wallet side.
