Tyre wear question

[CB ARGH]

Hey guys,

I had a look at my rear tyre yesterday whilst I was washing it and realised it's almost at the little wear line/bump/thing. The front wheel is also wearing a lot on the part of tyre that would be in contact with the ground when leaned over (edge of the tyre), but not too bad in the middle which would be in contact whilst upright.

Front: DUNLOP Alpha 10 (Done about 7,000KM)
Rear: DUNLOP GPR100 (Done about 10,500KM)

I do a lot of hard riding, around scenic, SH16, SH22 etc.

I'm just wondering if this amount of tyre wear is normal.

Sounds normal too me. Have a look at the front and see if it is starting to 'scallop' around the tread grooves (edges start to lift up). If so replace the pair.

Personally if you are giving it a bit of stick as you say and you've got over 10k outta them I'd put a pair on - it will handle a lot better than just replacing the rear and trying to get a few extra thousand out of the front.

Thats normal for a bit of hard riding - as it should be

Front: DUNLOP Alpha 10 (Done about 7,000KM)
Rear: DUNLOP GPR100 (Done about 10,500KM)

I'm not 100% sure; but I think the Alpha10 is a sport tyre that's road legal - soft sticky tyre - 7000 is a good life.
The GPR100 is not as soft - I think if you get 10,500 out of any rear tyre riding fairly hard would be good.
but I ride a 1200 - so it could be different on a smaller bike?

i had the exact same wear on a pirelli on my old nc30

just means you've been riding properly on the good roads

the wof guy was so impressed he didn't fail me either

Isn't it funny how it wears in the parts that makes the most contact with the road... Perhaps more time spent with the less worn parts of the tyre, in contact with the road....

[Edbear]

At 12,500km mine are barely showing any signs of wear at all...

But yours sounds normal for a sportsbike. Just be happy you don't own a 'Busa...

The GPRa10 is a dual compound tire from what I know, and its the softer of the two available (the other being the GPRa15). They are softer towards the edges for better grip, and are a bit harder in the middle for tyre longevity - the idea being that they wear out at a very similar rate, rather than the centre being flat and still having heaps more tread on the edges.

The GPR100 is the harder of the old style GPR's - the softer was the GPR70. I would expect that tyre to be worn on the centre more than on the edges.

Then you don't know much , GPR-al10 replaced GPR70 as Dunlops road legal sport production tyres for smaller bikes and the GPR100 replaced the GPR80 as the sport tour for same bikes , none are dual compound
