I've noticed just recently that when cornering enthusiastically, the tyres squeal quite a bit. Saturday, I had a couple of friends in the car and while they thought it was cool, it had me a bit worried that the tyres aren't performing up to scratch.

What's it likely to be? Are the tyres on their way out (unlikely, as there's at leat 4mm of tread left), or am I just starting to find the limits? Third option: is it nothing to worry about?

Roads have been hot and dry for a while so they will be rubberised which contributes to the squealing. I guess you're just pushing the car harder than before - maybe that's what Mrs Witchfinder has noticed too

4mm is about half the tread gone - I wouldn't expect any different noise at that point from normal. Mine squeals too, fun ain't it

Rob, If you havent done so already check your tyre pressures.

Otherwise I guess the squealing is probably accompanied by a lower mpg meaning you are just having FUN !!!!!!!!!!!!!

buy slicks they dont squeal... the trread blocks deforming and touching causes the squeal... hence when the tyres are hot and stick on warm tarmac they squeal more.

Hmmm... haven't checked them for a few weeks, so that might be a good place to start. Thanks.

Mine have never squealed. If I try and push it, the only effect tends to be a kind of scittering effect as it begins to oversteer a little.

BTW - Colin got his tyres screeching on the Wales run, but it never felt like they were under-performing...

Sidewall movement causes squeal, check your pressures.

Last night I got the tyres to squeal as well. Don't think tsidewall movemnet and/or low preassure caused it Link/pic :cheers:

Anyway, I too have noticed the hot weather is causing increased squealing and less grip. Think my Conti Sport is crap! Get so slippery when they get a little hot. Like most girls I guess...

Hmmm. 305/25, eh? Thats quite narrow, and BLOODY wide!

My old conti-eco contact tyres used to shriek a little, but they were narrow and the car used to slide quite easily. However, as above, my marshalls I'm currently running (205/40) have not squealed once yet, even in the heat of the sun. ( They just jitter a bit, whilst I hang on to the steering wheel )

The fab doesn't squeal unless it's a really hot day and i'm pulling out quickly (usually on a mini-roundabout).

The 'standard' octavia i had as a loan car squealed all the time mind you...

Think it's easier to get the back wheels of an Octy squealing due to the extra length of the car

meaning you get more sideways force at the back at the same speed...

Third order lever or something...mine were squealing all over the place, but I'm trying to get as

much wear out of them before they get changed

Rob.

Oh.. I get wheelspin quite regularly... - Or perhaps a bit of noise when I accelerate hard around a bend / roundabout in 2nd... Can't think of any other times.

you should try and RS....

Hehe - I got plenty of trying a few Saturdays ago :drive1: albeit in the passenger seat. :(

Paul - is it easy to get the wheels squealing on the/a TVR?

Rob.

I imagine just drop the clutch at anything over 1500 revs .... lots of blue smoke

Or put your foot down half way round a bend ... wheeeeeeeee!!!!

Is the TVR FWD? I was just thinking that flooring it on a bend in something like a 911 will result in you quickly facing the other direction... and if the TVR is RWD I don't they have traction control to help with spinning around on the spot. (good for do-nuts, I should think though..)

TVRs are RWD, and their idea of traction control is to give you long accelerator movement...

TVR=RWD with engine at front - not sure about their weight distribution, but anyway either heavier at the front or neutral. Hence pushing the back end out should be recoverable (depending on how badly you've lost it) by lifting off.

911=RWD with engine in rear , acting like a bloody great pendulum, so lose the back end and it's GONE...

Aaah! forgot about the old engine position being a factor... DOH!!!

I guess the TVR then will be a bit like a BMW in that the engine is at the front helping to counter-act the driving rear axles desire to spin around. Nick, I suppose your porker must be similar, as they're front engined too aren't they? the 928/944 models?

Indeed. 928/924/944 are all Front-engined, RWD, with the gearbox mounted at the rear to give, in the case of the 928, perfect 50:50 weight distribution. This means the 928 is quite forgiving, push it and the back goes out, lift off a little and it straightens up again. Of course, in the wet, and with a heavy right foot, you may not react fast enough, so respect is the watchword!

If BMW's are known to swap ends @ 50 MPH going in a straight line on a flat road.....then yes..was following one when it did... :(

Found it was quite hard to bend back fiberglass.....

Still was quite spectacular though!!!!

i would rather lose a 911 than a TVR, they are designed by people who know what they are doing rather than some peopl ein blackpool with a big pot of glassfibre.

There was a TVR based website I knew of a few years back. Had a page dedicated to crashes that owners had walked away from - a testiment to their survivability I think it was meant as...

On that page was a yellow Chimera (sp?) with the numberplate BAD 541T (geddit?). I had pointed that very car, parked in the car-park of a computer software training facility, ony about a month beforehand - The brash nature of the car and plate caught my eye. I'll admit that seeing it wrapped around a lamp-post, knowing that everyone was OK, was mildly amusing...

Regards,

Mark

Maybe the plate was an honest self-assessment of the driver's abilities...
