The tyre version 5 thread

Working as intended.

This has been discussed in several different places since the update, might try reading back a few pages - I'll post a link if I can find something. Basically the tyre temp mod now pulls numbers that are much more volatile from the tire surface I believe. You can get more detailed readings from the dev apps for the moment.

 

I just used the dev apps on a new install. It's the same results, temps raging around 20º on the same lap, and hardly going over 70ºC. I know I'm not the best, and definitely not the most agressive driver, but my skills should be enough to keep the tyres warm, which at the time they aren't.

Edit:
I think I may have found the problem: I was not letting the tyres squeal when I braked because I thought that meant I was locking up, when actually after the update they lock up way after they start squealing, it seems. Therefore i was not braking hard enough for the tyres to heat up.
Do you think that could be my issue?

 

Naturally you can't keep the same tyre temps all over the track. It will vary in corners and straight road. The more tyres are turning, more heat is generated.



Video description:
"Stock AP1 S2000 with JRZ single's and NT-01 tires. No aero. No power steering. MoTeC display & data acquisition system.
Front: 0" toe, -2.2 degrees camber.
Rear: 1/8" toe-in, -3.4 degrees camber.

Note: The two localized cold zones on the inside of each tire coincide with the tire's radial grooves. The IR sensors are fixed to the chassis and are reading the front surface temperature of each tire; therefore, interpret the tire data accordingly.

Realtime tire surface temperature measurements not only indicate whether a tire is operating within it's optimal temperature window, but arguably more important, accurately depict the load distribution at the tire's contact patch. Generally speaking, as the local pressure of the tires contact patch increases, so does the temperature (and vice versa). For example: the front tires of this car clearly need more negative camber, as much of the load is on the outside shoulder of the loaded front tire during heavy lateral loading. Measuring tire surface temperature is essential for tire exploitation and is why so many teams in the upper tiers of motorsport do so."

And here a video from F1 tire surface heat:

The load under braking usually doesn't contribute enough to heat generation that it would make a big difference. Keep in mind the new tire model is still wip and will change with future updates

 

No not a flat spot, a puncture AKA flat tyre.

 

Is it possible now to have a puncture?

 

Yes

 

Yeah ive had a rear right tyre explode after a spin and then just to mess around i was flooring it to drive away. The tyre reached over 230c and it exploded, showing a full red tyre in the damage icon.

What confused me is how i got put straight back in the pits shortly after. It was in a practice session so thats not the end of the world, but if for some reason someone gets a blown tyre during a race its not realistic to do teleporting...

 

I do hate the teleporting thing in AC. I really think there should be an option to turn that crap off and everyone just drive to the bloody pits like a human beings, rather than going all Star Trek.

The graphical representation of puncture was to drop the wheel that got the puncture through the road to the rim level, which is ok I suppose, and it actually even felt like a puncture. I was little surpriced at first since never had one in AC, so took me a second to figure it out, but Kudos to Kunos, that is attempt of realism which is always the kind of progress I like to see.

 

oh, in some older sims it was test of your inner zen .. crowling back to the pits for repairing puncture (after you lock and rear ended somebody or just had bad luck with contact) if it happened in first few corners .. but still the right way to do it

 

Please no teleporting due to damage unless server admin sets it ON on their server.

Any tyre temp. apps that show correct values? I've tried the latest Danny Giusa's tyre temperatures 1.6.2, but compared to the suspension app that shows temperatures and suspension it was wildly different. Not just higher or lower but both at different times. Simply showed what might have been V4 data while suspension app showed V5 data...

 

I tried the McLaren GT3 last night and for the first time, I encountered a driving scenario where I don't think it was "as good" as before. The FFB just didn't seem to give the same amount of information particularly when the rear end was coming around.

 

I have just completed another practice session @ Vallelunga Club in the Alfa Romeo 1600 GTA. This time I set the track conditions to Green, with a track grip of 93%, and an asphalt temperature of 17C. I also ran a control test again with the default optimum conditions. My best lap times were as follows.....

Optimum: 1:01.445
Green: 1:02.473

So, the difference in lap times is evident. However, I was expecting the car to slide around a lot more with the Green track conditions, but that was not the case. I could detect subtle differences through corners, but that's all they were. This is not a criticism of the tyre model for the Alfa GTA. It is just an observation, and my (possibly naive) surprise at the relative stability of the car under these conditions.

 

The GTA is borked right now.

 

I have not seen confirmation of that from Kunos.

 

defo borked, it's a half-track

 

Aris confirmed in Sodano streaming

 

Thanks, Luca. Is that the only car affected? The GT40 also has vintage tyres, and has been upgraded to the v5 tyre model.....

 

GT40 was made on V5, GTA was updated. I'm sad to hear one of my favorite cars GTA is botched at the moment. Have not tried it yet with V5 but on V4 it was a handful.

 

Great to see that. I wish to know the caster and the tires pressure used.
