Default Tyre screeches when making turns ?

while making a turn on a flyover there was a screeching/squaling sound from them.. could it be because of the cement surface or due to under/over inflation of tyres ? the sound came from start to finish of turn

This particular sound comes when you are cornering under hard acceleration and at a high speed which the tyres can't hold to. Screeching sound is just the start after which you sometimes hear crash-boom. Its basically throwing your car around at absolute limits.

This sound can and does come at times on certain vehicles when turning with full lock. It could indicate a few things:
1 - You are simply nearing the limit of the tyre. This an be true even if you are taking a tight turn too fast. Sometimes 30 or 40kmph can be a bit fast as well.
2- Certain tyres are known to be a bit noisier than others. nothing to worry about here.
3 - If none of the above, it could indicate an alignment problem.

Cement also makes this sound more apparent/frequent.

Another probable cause could be old & hardened rubber in your tyres, that also leads to tyres squealing prematurely even at low speeds.

When I had tubed Bridgestone S322 tyres they used to squeal a lot upon cornering. With tubeless tyres I find that there is much less squealing upon taking corners at even higher speeds than before. This must be due to the fact that tubed tyres deform a lot more upon cornering. Low tyre pressures should also increase tyre noise upon hard cornering.

On smooth cement surfaces the tyres can squeal at very low speeds. In my company basement parking area most cars (including mine) generate an awful lot of tyre noise while turning even at 15 kmph.

I think, the difference you are experiencing could be due to newer tyres (new rubber, better grip) rather than change from tubetype to tubeless.

All you have to do is take a look at the dash to remind yourself. LOL

Could it be because these are hard compound tyres ? what tyres are you running in your 1.2 ?

Had a similar problem when i started filling air at a new place. Turns out that lower tyre pressure was the problem.

100 bhp engine ,coupled with 175 sized tyres and a sharp turn on a concrete road can cause the squealing.

That is certainly one reason, thanks for pointing it out. And the tubed tyres I had were very old (5+ years), so the rubber would have hardened. Still, I am able to take corners at 10-20 kmph higher speeds without any noise from the tubeless tyres (which have run 19000 kms now), whereas the tubed tyres made an awful racket.
