No, it´s not well explained. In fact there are 2 different explanations from different members (that contradict each other) and both can be proved wrong:
- It only displays 50% of the wear: False. It displays different portions of tyre life on different cars. You can run ages safely with 0% in some cars, you can´t run more than a lap or 2 in others after hitting 0%.
- It only displays the tread wear: False. Some cars keep getting faster on what this theory would suggest to be the carcass.
The second probably explains how the indicator works, but exposes flaws on the way the actual tyre is behaving.
You don´t have a clue what you´re talking about.
Here you have how grip evolves on a road tyre as you wear your tread depth. As you can see, maximum grip is achieved on brand new rubber with maximum tread depth. Grip decreses gently as depth goes down, and it takes almost 2x the distance to stop your car even before running out of tread!
It doesn´t even take reaching the carcass for the grip levels of a road tyre to decrease dramatically, yet in the game we can reach it, run on it, and drive as fast (in fact faster) as before!
Empty chatter with 0 content. The carcass by definition is a part of the tyre meant for a structural function, it´s not meant to be run on, and that´s why it´s provides no grip once it´s reached.
If that generalization I made is wrong, surely you´ll have no trouble finding footage of someone in any type of car running on the carcass doing the same pace as they did in brand new rubber (in fact more than 1 second faster), as I was able to do in the game. Go ahead.
From a SMS buddy of yours that knows a bit more than you: "it only displays tread because you should never aim to run the carcass". This guy knows how it works like, but misses that in the game is currently not like that.
You do well trying to reach for authority as you´re not doing well on the debate yourself. But I got bad news: the fact Ben Collins helped with something doesn´t mean the result achieved is accurate.
Example: He hailed the accuracy in the performance levels of the FB compared to a GP2/superleague second tier single seater, and I´m running F1 pole position laps with it on race trim.
The truth is tyre wear isn´t working properly in the game. There´s no wear and degradationon a lot of different tyres in PCARS. You run full grip until you reach a point where you just get damage. The tyre goes from giving full grip to start wobbling as if it had a puncture.
That needs some serious work on it, and it would be better for everyone if the shilling stopped, the issues were admitted and adressed instead of sweeped aside with lame arguments. In the end we would get a better product. If that "everything is OK" attitude continues we´ll end up buying shovelware because they get away with it. And we´ll be to blame.
If something is wrong, what you do is checking it and fixing it. Not sweeping it aside with rubbish. There are plenty of examples. Right now camber adjustments don´t do anything to the I-M-O temperatures. Instead of working on that, you tell them about it and get replies like "we don´t have enough lateral definition to display it, but the effect is there". LOL. You have 3 measurement points! Who you think you´re fooling with that?
