tyes

Thanks Barry,

If you look closely around the tread, you'll see little bumps at the base off the tread pattern. When the top of these Tread Wear Indicators (TWI) become level with the tread, the tyres are needing replaced.

If I remember correctly what was told to me, the wear indicators on the tyre are actually 2 mm. and the legal limit is 1.6. I always replace my tyres well before either point because they feel scary below about 4 mm.

Funny.

Worn tyres are better in the dry than new ones. fi yure tyres are scary at 4mm you either need better tyres, a better car, or better driver ability.

Utter crap.

Think ton and a half of Volvo 740 Estate - then put your brain in gear before your mouth.

Funny. Never had problems with 1.4 tonne and 192bhp of BMW down to

No, it's quite true.

Like I said.... ;-)

I've had cheap new tyres that slide around all over the place in the wet & I've also had very good very expensive tyres worn down to the limit which had more grip in the wet.

I also have an estate which can be a little scary if I rush into a corner a bit too fast so I drive accordingly in the wet. I certainly wouldn't think an extra 2mm of tread would make all the difference.

I think you have to compare like with like! You need to compare some "good very expensive" new tyres with your "good very expensive" worn tyres. I always think new tyres grip better. I put it down to the compliance of the deeper tread.

The important factor there is the fact that the bald good tyres were STILL better than the cheap s*it, despite being knackered.

It's more of a subtle clue as to what an incredibly bad idea cheap tyres are than a pointer towards worn tyres being better than new.

Wrong I'm afraid - over (too many) years of driving and differing makes of tyre, I've also found that when they get close to 2 mm there is a deterorairater (or however you spell it), and not just when it's very wet either. This has been common to Goodyears, Michelin (even the old and legendary X's and XZX's), Dunlop and others. But at 4mm I don't seem to get any probs. Have always replaced @ 2mm minimum.

Bald tyres are only scary in wet weather.

Checkout formula one tyres for your answer.

You can't sensibly compare two such different circumstances. If you could get your road-going Michelins or whatever to the temperatures reached on a track, then yes worn tyres would ultimately offer more grip. But you can't.

Road tyres aren't designed to be run as slicks.

Read my other post about compounds, and gain a desperately needed clue.

So why do formula one cars need new tyres every 50 miles or so?
