Weird line in both tyres

[Clutchy]

Got a good feeling I'm going to make a big nob of myself here but here goes.


There's a large line gouged into both tyres which goes all the way round and is exactly the same on the front tyre... No idea how it could be like this as the front and the back have the line in the exact same place.


My suspicious are that its a wear indicator like when it disappears you should change.

Two reason I don't think it is this is because it used to be a lot deeper than it is, but even if the line fully disappeared I still currently have loads of tread left.

The other reason is that the line is off centre.

So... Any idea? Need to zoom in on pics.

That's weird, I thought u where gonna put the classic compound edges up bit that's deffo not that. Bit of an off wear indicator if u ask me, it goes all wiggly for a start!! Is there much of a groove in the tyre when u run your hand over it or is it just colour difference?

What brand of tyre?

It's the anti static strip nothing to worry about.

They're bridgestones forgot the model, will post later.


The grooves been there since I bought the bike as far as I know, about a thousand miles ago it was probably 1.5mm deep, its now around .5mm deep.



Very strange

Seen that on my mate's bike, always wondered what that was.

Looks like a join from the molding process

As above, it is particularly noticeable on BT023's for some reason.

Interesting thread, I have a similar line on my front tyre and wondered what it was, it had started off as a yellow line but has worn down and is darker than the rest of the tyre.

At least I now know it's nothing to worry about

offtopic, but...

Has anyone ever actually got a static shock off a bike? Granted, the tyres are rubber and hubs tend to be fairly good insulators as they are coated, so will develop a charge as they rotate. However this will dissipate fairly rapidly into the air as it has such a massive surface area. Reminds me of the 80s when people used to put those conductive rubber strips on the backs of their cars. Dad never put one on his, and I can't ever remember getting zapped either.

I know I haven't. Even yesterday which involved accelerating up to 60, stopping and touching the rear to check for brake binding as my new pads were a little tight.

Contrast that with spinning rotor blades that can develop a couple of hundred kV under the right conditions. When flying at night we'd sometimes see a faint blue glow coming from the edge of the disc, which is the corona discharge from the tips.
