Does bike tyre tread all of a sudden just go?

[AshWebster]

I'm used to running car tyres to the end of their lives but bikes is a different matter. Went for a ride out yesterday not a massive one, tyres looked fine before i went.

Took the bike out this morning and first thing i noticed was down the middle about an inch wide covering probably 70% circumference was like patches of tread missing (almost like a layer of tread).

Do they just go all of a sudden? (im pretty sure these are shot now right?)

Battlax i think

What tyres?

Yep. It seems to be more of a thing these days - it's happened to me twice. Keep an eye on the wear indicators and as soon as the tyre is down to those, get it replaced even if the tread looks adequate. There will be a marker ("twi") on the edge of the tyre to tell you where they are.

Yes, I've had one go from just over the wear bars to canvas showing in 200 miles. That was am M7RR.

Admittedly 200 miles of high speed on dry, high wear roads.
