Tyre wear question

[Groins_NZ]

My front tyre is starting to wear unevenly i.e. the right side is wearing at a sharp angle but the left is still rounded from the centre to the edge of the tyre.

It's done approx. 8000Km but the tread wear is only half worn.

This probably shouldn't be happening right?

I have seen this on a couple of other bikes owned by other people.

Any comments as to why it is happening would be appreciated and is the problem correctable before it gets any worse?

Cheers

Are your favourite corners on heavily cambered roads?

[vifferman]

Two things: the road camber does commonly wear tyres here more on the right side than left (other way round in Urp and Murka), and you may possibly have summat out of alignment. It's not likely, but does happen.

Ask the M/C tyre places - they'll tell you unevenly worn tyres are very common. Think about it: almost all roads are cambered to allow water to run off, so when you're riding along straight, the bike's leaning slightly to compensate so you don't run off the road.

Normal on the road. Camber etc.

You must have some decent roundabouts on your trip to work! Are they good for a few laps before other traffic shows up?

Uneven tyre wear is one of those things. I particularly like the way that the front will tend to wear into a triangular shape while the rear wears square. Great for stability on quick-steering bikes - not.

I wouldn't worry except to keep an eye on the tread depth where it's wearing. If it's wearing, you must be loading it up, therefore when it's wet it's more likely to let go when you're wearing out that bit. From what I recall, the front letting go while you're busy wearing out the edge of the tread is a Bad Thing.

Enjoy!

Sometimes it's a particular batch of tyres - the Dunlop TT100 has been around for over 30 yrs,they were originaly developed for the Triumph Trident,and you can still buy them today,in race compound for classic racers.So there are some people who have spent most of their life riding on TT100s,and have gone through dozens of them....and then had one wear more on the right side,very strange.Same rider,same bike,same roads...a triple blind.Gotta be a bad batch of tyres - ''Dunlop'' no longer exists as a manufacturer,it's just a brand name to slap on tyres made anywhere,so a lot of TT100s are Taiwanese.

Most likely road camber. I notice this more on sport tourers than sprots bikes.

The picture below is simplistic, but shows road camber and where the tyre interfaces with the road when riding in a straight line.

HHHHMmmmmmm I hear ya all but then my previous front tyres didn't do this (different brand though)....?

Maybe it was just the 2000+Km I did in the weekend that's done it because my commute is predominately on the motorway which has little camber - I would have thought.

all sounds pretty normal, technical reasons exist but ill just blame it on the tire pixies

[TwoSeven]

uneaven tire wear is typical on commuter bikes, if it gets noticible, replace the tire.

AT INTERSECTIONS THERE ARE 1/2 LEFT 1/2 RIGHTS AND ALL THE RIGHTS ARE FASTER THAN THE LEFTS CAUSE OF THE SIZE OF THE ARC

ok, so this thread answers the "wear more on one side problem", Not that I have that yet, but understand the cause there of, road camber.
I have read the other thread re the "cupping" of tyre, but that was about a rear tyre cupping if I am right,
So what if it the front tyre that is "cupping"?
My Tyre wear issue?
There is a 1 - 1.5 mm taper from the front of the tyre block to the back of the tyre block.and is heavier wear on the centre of the tread area as opposed to the outer edge,sidewall edge
Tyre Shenko 100/90/19 57H
Tyre is at 28psi, this is on my 79 XS1100 yamaha.
The trye is no more than 5000k old.
Is there a cause for this?
Bad tyre construction,forks need maintenance,front rear shock balance wrong.
The rear shocks are set at minimum, and I only weigh 70kg, never carry a pillion, rear tyre 3500k old - even wear across its face.
Bike is only riden on the open road.
I hope this pic will help to sort this out.

I suspect that you're running a dual compound tyre, and the Hornet has decided to grind off that soft sticky shit around the sides, leaving the harder stuff in the the middle.

Try a set of Avon Storms and cure all such ills.

all my bike tyre ive ever had wear uneven on the front , its a combo of corner and the road camber .
the road camber wil always square the right side harder and the left side should be slightly worn but will be more so curved and flattish.
nothing you can do
