You know it's time for new tyres pronto when

[Welsh wheels]

You check them and they look like this....

 

[Bollo]

Just scrubbed in. Plenty left in those.

 

[roadrash]

are you mad!!?

Gaffa tape is totally the wrong color, felt tip pen is the sensible answer, comes in loads of shades.

Proper job

 

[roadrash]

felt tips are cheaper too, win win

 

[Markymark]

The above are just idiots - gaffer tape indeed.

Photoshoping the photo will cost nothing and they'll look perfect.
EDIT:

In fact here you go, problem solved.

Wait... you had to check them before you noticed all that fabric showing?
There's more textile fibres showing on there than on Wayne Rooney's scalp.

Uncanny likeness.

Great, I can sell you the old ones. As you said yourself, there's plenty of life left. Shall we say 20 quid for the pair? Jokes.

I did notice the bike was handling weirdly last night on the club ride. At least my clubmates didn't know my tyres were in that state, they would've had a fit!

Changing the tyre just before it goes pop is a win. Max value for money.

I did have a tyre that went pop once. It looked like that as well, which I only realised after it went pop.

Wow. You've had your money's worth out of them.
As a point of interest where do we stand with the law if the boys in blue noticed a bike tyre in that condition. In the real world they probably wouldn't bat an eye lid but if they went " by the book" could we get into trouble for using a bike with defective tyres on the highway.

@Welsh wheels
Is that a 7 speed cassette? Quite unusual!
