I have been diging around at my parents house and found a set of early GT tyres I had on my bike many years ago.
Unfortunately the sidewalls are in a real state. Has anyone done anything to improve the apearance of these. It's a shame as 1 still has the GT letters along the center rib.

Get some pics up of the problem, I may be able to help

Cheers for the replys. It's the amber sidewall that is the problem the tread rubber seems ok. I did wonder if a very light rub with something like scotchbrite would remove the brown flakey bits that are on them but you would loose the GT badge that is still on them. I had a similar thing with some old comp 3's but they actually started to fall apart as well.

I will try and get a picture or two up later.

Ah, the brown flakey bits.......like this?

That stuff is like a protective layer of pva over the tyre core. It bubbles up and gets shitty with age as you have seen.

Leave the tyre on a wheel pumped up.
Boil a kettle and plonk the wheel over a sink.
Pour the boiling water over it 6 inch sections at a time. It'll soften the shit.
Get a stanley blade and with a flat edge scrape it away.

Comes off real easy, it'll take a few tries to get it all away but the results are well worth it. Skip the logo'd area, that'll come away too. It leaves the core without that protective layer but I don't think it matters.

Hi
Yes thats how they look although slightly worse. I will give it a try on the comp 3 that is really bad.
Thanks for putting up the picture and doing a quick how to.
They probably won't be rideable now but at least 1 of them could be used on a show bike.
Ended up laying under the car fixing it all evening so didn't get the chance.

You need something a little more flexible, I have no idea what though

Thanks for the suggestions. I don't know if the surface is porous but wonder if watered down PVA would be any good, it might work if it soaked in and would be a bit flexible then.

When I get a spare few minutes I will try a few things.
