Pete
Shaun, I don't understand how folk can say the SS isn't quicker than the Soft - it IS quicker, you've just got to look at practice and quali times to see that it is! 


I thought I explained it pretty well really.... 


In the case of Brazil where 2 cars where on similar fuel load but the soft tyres were 5 laps old and the SS were brand new, from the very first lap of the stint, the laps times were almost identical and the gap maintained at almost exactly 2.5s for 8 laps. The only l difference was accounted for by luck with DRS.

This is contrary to what you would expect in race conditions.

I would have expected an initial advantage to the SS (with current wear I would have thought 5 or 6 laps??) to extend my advantage and then the soft tyre would have started to gain.

I just ran another race after the night. Yesterday 26 degrees, all tires with good yield, the SS bit worse by the temperature. Today ran with 14 degrees, SS and S sent in the race, but not only so the M and H failed to have a reasonable income at low temperature. But from S to H again giving gameplay and aggressiveness. So I'm more than forced to acknowledge the effort again and say hello. They managed to make the game more real and balanced the tires. thank you for understanding my previous dissatisfaction, but this game is about my daily vice !!! congratulations

Perhaps to compensate for the lack of speed and ability to earn the track record achievement, it might be time to introduce the US tire

First race completed with the new tyre update (75% race) and I gotta say first impressions are really good; SS and S compounds much closer together in terms of speed and Meds out-performing Hards which is also great to see taking into account the track temp of 16 degs, Med-runners actually finishing in the top 10 too!

Great job Jack and the rest of your team, it's hard to please everyone with updates but i'm certainly pleased with it.

SS = quali tyre/short opening stint tyre
S/M = normal race tyres depending on track wear rate, temp and car development
H = extreme heat/wear rate tyre

Sounds like a great balance to me.



Completely agree with you there Pete. With 4 usable tyres in a race, there will be a lot more strategies, and more skill involved in selecting and managing the right tyre compound. Much better than having predominantly just 1 tyre.

-----------------------------------------------------------------------------------------------------------------------------------------------

Worked out some numbers overnight, which should get all 4 tyre compounds, to a very similar race pace:

Scaling

-Scaled from old tyres, to produce as many different usable strategies, particularly at 100% distance, and 50% distance.

100% distance: x0.75
75% distance: x0.90
50% distance: x1.0
25% distance: x2.0

Pace

-Base laptime difference between tyre compounds. ie. in Practice (on a median length track, 60laps; 100% distance, 30 laps; 50% distance)

SUPERSOFT >> SOFT: -0.900s
SOFT >> MEDIUM: -0.375s
MEDIUM >> HARD: -0.550s

Note: I've taken into account variable push levels, so true gaps will be closer.

I like having to figure out new strategies based on changing dynamics. It makes it interesting. In my last race, it didn't go my way at all. But I like the challenge of having to figure it out. Wouldn't it be boring if in real life, everything was the way you wanted? It took me a while to experiment and make mistakes in the junior leagues and even elite before I was competitive. It was fun trying to get better each race. I like this transition period with the tyre changes. Makes you think. Thanks Jack.

I think the dry compounds should have the same laptime delta between each type of tyre, maybe around 0.5s difference between each step. That also opens up the possibility of Ultrasoft, which is slightly faster than the Supersoft you proposed.

I could be wrong, but I don't think Ultrasofts are coming, sadly.

Current gap between Supersofts and Softs is -0.650s/lap, and it's fair to say it's not a big enough gap, at the moment. Softs seem to outperform Supersofts after about 5-6 laps in a 100% distance race. And this is with Supersoft scaling at x0.50

My opinion is according to 50% Race -->
SS Speed 1.000s - 2.000s faster than H With the same car/driver adding balance of driver error  (all tracks)
S  Speed  0.750s - 1.350s faster than H With the same car/driver adding balance of driver error  (all tracks)
M  Speed  0.300s - 0.750s faster than H With the same car/driver adding balance of driver error  (all tracks)
SS Wear 5.0% - 30.0% min - Max for every track according to Tire economy too.
S   Wear 4.0% - 22.5% min - Max for every track according to Tire economy too.
M   Wear 2.0% - 10.0% min - Max for every track according to Tire economy too.
H   Wear 1.5% - 7.0% min - Max for every track according to Tire economy too.

TE should step up to 30%  till 50 points (SS in track that have 30% wear with 1 point of TE at 50 points of TE should be 22.5%)   and cover the rest 70% up to 100 points.

I suggest adding temperature operating range to tires in a way of more lower speed on cold tires and very high wear on hot tires
I don't like the new way of pushing tires but if is to stay i suggest PL1 to have a big step and be slow to cool tires and PL5 also big step with bigger impact on Driver Health / Fuel usage / Tire Wear / Car and Engine Wear. So mostly usable level will be P2-P4 for on all conditions and tires.

Just finished a 50% race. Had the chance to finally compared the new Soft and Medium tyre directly. Mediums appear to be a clear 1 step 'harder' in Push Levels compared to Softs now (Used to be a +0.5 Push Level difference)

After more comparisons in races, the same also seems to apply with Supersoft vs Soft (Clear 1 step, instead +0.5PL beforehand)

So, with newer data, chart needs correcting

Scaling

-Scaled from old tyres, to produce as many different usable strategies.

100% distance: x0.75
75% distance: x0.90
50% distance: x1.0
25% distance: x2.0

Pace

-Base laptime difference between tyre compounds in Practice.

SUPERSOFT >> SOFT-1.150s
SOFT >> MEDIUM-0.625s
MEDIUM >> HARD-0.550s

Apologies for any confusions

Have you taken into account the time lost from starting far down the grid, temperature of the track and differences in fuel levels?

Without that you could get some pretty random results every race (and unfortunately maybe even the same exact tyre being the fastest every gp).

Yes, taken into account. It's about +5.00s for every 10 grid slots (qualifying penalty for each harder compound used)


Traffic has also been taken into account. I've given +7.50s for traffic, for strategies with an additional pitstop, hence why SS is a little quicker.

Also scaling means SS hits the 50% degradation cliff sooner, so for SS and Soft to be viable options in a race, SS needs that pace advantage before hitting the cliff.

  • All tyres now heat up less, or have to be pushed slightly more to get heat in to them



Is it possible to do this with both wet tyres as well? Just a little bit.

First, I would fix the issue of starting consistently with the wrong set of tires in case of rain... look at the race tonight, everyone had to pit after 1st lap.

Please allow us to change tires on the grid! It would push players to play live...

I raced in Monaco today. It was 28degrees and put the ss tyres for 20laps. I had medium push and they didnt overheated. The s tyre however i had to push to the max for ideal temp. Normally i would expext to rûn medium or hards with that temp or at least the s tyre. I suppose you can run the ss until 35degrees without overheating. Rather strange in my opinion

This is Monaco. This is realistic. Look at formula one, they can use ultra soft and last forever. No wear no heat

I'd like to give my feedback after my last race. I just raced Bahrein, 34°C, and due to the temperture super soft tires wear out quickly. Soft tires were ok and medium tires were great, faster than hard and had a very closed gap to soft tires. I race in a very competitive race and, after tires update, we had 4 different winners in 4 different races. So, in conclusion, tires update are very interesting and bringing more challenges. You guys are doing a great job

Dear Jack,

Today I can't save the tyre strategy, please fix it

Thanks

Please check now, is it fixed? Looks okay here. It was a change uploaded late last night which was causing this problem, and it has been rolled back now.
