I don't believe since the so called 2.0 NTM came out that they've said that any car has tyre wear, have they Phil? Could be wrong but didn't think so. They've always said lack of grip comes from the tyre temps only.... never due to less rubber left on the tyre..... That's promising to actually have some form of wear like there was in the NTM 1.0
From 6/7mm of tread to 3mm not so much but from 3mm to nothing you would be supprised.. My r888's feel noticably less grippy as they approach their wear markers (1.6mm) if you keep drivinv the tyre just gets harder and harder reducing the grip.
Yea but this is real life. Where repeated heated and cooling of a tyre reduce the performance of a tyre's surface.
It won't be the tread depth that has any influence on grip levels. It will be every other kind of wear. Unless you're on the canvas there will be no difference. I mean it's a shitty analogy but it's still true. Take an eraser, it isn't any less effective just because of it's size. That would be like saying dump truck tyres have more grip just because they have a bigger tread depth.
Less rubber on the tire means that the rubber on the surface has less of the rubber to dig into the road with, so to speak.
If you take a microscope and look really close to a tire you see small hairs everywhere, threads across etc, the more you wear them down, the less the tire will have to work with, and the less friction it can withstand.
Comparing the two is completely irrelevant, it just doesn't make sense.
Well the reason I commented is because it sounds wrong but of course. Even so this is comparing road tyres to race tyres in terms of the experience I have, and teh experience you have and as you rightly said, comparing the two is silly.
Yea but this isn't solely because of tread consumption. There's thermal degradation involved. That's my point.
But as we said, it's silly to compare them. A race tyre will probably never get used again once it's been dormant for 24hours where as road tyres have big inactive periods which depending on the thermal circumstances can soften/weaken or harden the tyre.
Well clearly. You should have thought about it a little more.
We already know that temperature is one of the factors. We also know that track temperature (well whatever the weather is set to anyway) can make a difference to grip levels. Why do you think that they would bin all the other reasons and make tire thickness the sole reason to lose grip?
