Tyre wear and FFB question

[mattikake]

Could be a bug to go in the bugs thread in which case I'll just delete it, but I'm wondering what this is, if it's supposed to happen and if other people have had this or have ideas on this.

Basically I was testing for an upcoming league race with a race against the AI. 22 laps of Spa. By about lap 15 my tyres were about half worn and grip wasn't quite what it was (Actually I was expecting something like PC1 with the grip fine until a sudden fall-off when the tyres had gone but it seemed like a progressive loss of grip. ). My G29 wheel started to clip occasionally on the straights. This got progressively worse until by lap 20 when it was clipping permanently on all the straights to the point it was almost impossible to keep in a straight line. Turning the gain and volume down on the wheel made no difference.

It seemed related to tyre wear but I can't see why that should be. If anything you'd expect some excessive FFB in the corners, braking and traction zones surely, not on the straights?

This is the first time I've run long enough in any race to get the tyres at more than 50% wear.



You can see from the graph the wheel is clipping horribly. Yet the Raw, 90,85,85,15 settings are what I use for most things and this same car - McLaren 650 GT3 - on other tracks.

I read somewhere here that the “usable” tire is till half the graph. Maybe your tire has less rubber to absorb impacts, making the impact harder on the wheel, and that makes it clip?

It seemed fine riding kerbs. You'd think it would be worse there too?

 

[Nando deBem]

I don’t think so, because curbs are my only complaint about this game. I can’t feel them at all, no matter what. Track bumps and inclinations I can and they’re great.

The vibrations are from driving on the tire carcass, which starts at 50% tire wear on the indicators. At 50% in game you have 0% tread and 100% carcass.

Really? Where did you read about that? That would explain a lot. But surely the tyre indicator should display 0% usable tyre left? 50% I took to mean I have 50% usable tyre left, oddly enough. It sort of makes the indicator wrong? I'd expect a hell of a lot less grip in the corners if I was on the carcass. And if so, what does 0% left mean?! I'm driving on the rims?

Various threads, it’s been talked about quite a bit. It’s odd the way the indicator is set up and I agree the carcass having the same or similar grip to the tread is probably not entirely accurate. You’d have to do an extremely long stint, at least 2 hours in most cases, to get the tire down to zero on the indicator.

I'll validate this, I've seen it discussed multiple times on the PC2 forum, including directly from SMS/WMD members in the know.

And yes, if you have 0% left you're basically driving on the rims.

Wow well I never expected the tyre wear indicator to work like that. Duly noted. Thanks.

That raises the question - are punctures modelled?

It worked like that in PCars 1. You've been too busy with your petition to notice

 

[mattikake]

Ha.

PC1 the tyre indicator would wear all the way to nothing and even then you had a lap or 2 before the tyres went completely. Indeed my FFB was setup so that I could feel when the tyres had gone in the first braking zone I came to. Seemed totally different to me.

In PC1 it was initially the same as it is now in PC2.
A patch in PC1 changed the indicator to only show tread wear.
