Looking after new tyres

littledove44

Following a recommendation on this forum I bought some gp4000s. Seem great, a little quicker than I had before, but what do I know?

Anyway, in prep for this weekends big ride I had a close look at them. Still smooth and unmarked after 200 miles, but there are half a dozen small holes. Quite round, and perhaps 1mm in diameter. Like a grain of sand has been embedded and fallen out.

Should I do anything? This weekends ride is very important as it's for charity and a puncture would spoil my day.

I have read you can fill little holes with superglue. Good idea?

Thanks.

just pick out any embedded bits of sharp stuff, otherwise leave alone

small cuts don't matter, any large+deep enough to causing bulging or the allow the tube to poke through require either a tyre boot (internal reinforcement patch) or binning the tyre

Are these the holes that Continental have in the tyre to judge wear?

Just a thought, I have just fitted the same tyres to a bike. Is it possible that these holes are the wear indicators, as mine have these and the holes a maybe 1 mm or a bit bigger? The sidewall has the mark "TW" in line with these holes.

They're the tyre-wear 'checkers'.

I will pop out to the garage and check.

That's definitely it, thanks. Two symmetrical holes on each tyre. TWI on both sides of the sidewall, directly opposite.

You live and learn.
