Help with tire wear and PL

Hi all,

I am new to the game and I am really enjoying it. I've only played a few races in my first season and my second season has just started. I've spend a considerable time reading about guides and best ways to develop drivers/cars and strategies (beginning + advanced guides). I pretty much did everything that it was suggested as best as I could (even calculated more specifically things like tire wear and fuel consumption from practice results using multiple tires).

For my first races, I achieved best car setup for both of my drivers achieved. I have tried my drivers so their physical are very good and technical aspects are also improved (around 6-7 for all attributes) although I have not touch on Mental development. I'm still in a Rookie league but consider my drivers to be overall to be competitive. I've managed the pole position with one of my drivers (driver 2). The race was in Australia (58 laps) with relatively low temperatures (around 6C) and no rain. My strategy was the following:

Driver 1 (qualified in 9th position):
S for 29 laps (predicted wear at 23%)
S for 29 laps (predicted wear at 23%)
with enough fuel to total laps minus 2 (my strategy was for PL1)

Driver 2 (qualified in pole position):
SS for 15 laps (predicted wear at 21%)
S for 29 laps (predicted wear at 23%)
SS for 14 laps (predicted wear at 23%)
with enough fuel to total laps minus 2 (my strategy was for PL1)

I've set the PL very low after reading a few guides (including the beginner's guide pinned on the forum main page which basically recommends PL1 or PL2 for "dry" tires). I also calculated the tire wear following some guidelines (assuming a 10% wear and lap # corresponds to beginning of lap, and rounded to the nearest integer):

lap 0 = 100
lap 1 =   90 = 100 - ( 100 * (10/100) )
lap 2 =   81 =   90 - (   90 * (10/100) )
lap 3 =   73 =   81 - (   81 * (10/100) )
lap 4 =   66 =   73 - (   73 * (10/100) )
lap 5 =   59 =   66 - (   66 * (10/100) )
lap 6 =   53 =   59 - (   59 * (10/100) )
and so on

I was wondering if this is the correct way to calculate lap-by-lap tire wear based on overall wear %. Any suggestions???

After 2-3 laps, both my drivers start losing lots of positions (Driver 1 falls to 21st while Driver 2 to 8th). After a few more laps, Driver 1 locks into the 26th and Driver 2 is in the 15th position). My tires are not that different from most of other drivers (they opted for S mainly with a few with SS).

The only thing I noticed while watching the race is that the temperature pointer drops considerably for both to the lowest level, and the only thing I can think is that the same way we need to avoid overheat (red area), I should also avoid excessive cooling??? Any idea.

Apologies for the long message, just wanted to give as much info as possible. I'd appreciate if anyone could give me some advice. Great online game.

Cheers,

Thanks Kevin. Is there any guide available after those changes? For example, I'm also interested in knowing if there is an optimum air temperature range (weather) for each available tire.

Thanks again Kevin. This might be a silly question but how can I find out about top Elite managers; strategies from previous season? I can check the standings from previous seasons (but without information about race by race). If I check the race that just happened, I can export the final results with not much more information than best lap, top speed, and number of pit stops.


Cheers,

Sorry Kevin for budging in..:)

Wait, why did nobody respond to that part of the post, yet. Weird.
Yes, Rafael. Of course tyres can be too cold, too. As u stated, race was at Australia (winter right now) at 6°C. That pretty cold! In such cold weather, u have to use SS and S (you did) and ride higher PL! Rule of thump: Every 10°C equals one PL.

According to my data, AUS at 6°C, SS are PL2 and S are PL3.

Are u aware, u are able to change PL during race?

Ambiant air temperatures do seem to effect what PL I can safely run without overheating or how far into the red I can run without losing time. But the guide was written for a different version.

You also did overfuel your car to make such long stints work, which also cost you a lot of time.

What was your tyre wear for SS and S in percent in the practise laps? Just calculate with that instead. Lets say S had 6% and SS 12% tyre wear. That makes 100/6 = 16 laps on softs and 100/12 = 8 laps on SS. That is what I consider a good rule of thumb of how many laps you can run on a specific tyre. BUT don't forget to consider how much fuel you need to make this work. Usually more than 50L of fuel slows you down considerably.
So if you come into a situation where you might be able to do more laps than 50L would allow for (usually on medium or hard tyres since they have less tyre wear), choose wisely and weigh the pros and cons. Or experiment around a bit and see what works better and what not.

Hang on here, 100/6=16 as a linear equation it leaves you with bald tires at the end of the stint and way behind the track. Going lower than 40% wear is suicidal...lol!   

1. 100-6%=94


2. 94-6     =88


3. 88-6     =82


4. 82-6     =76


5. 76-6     =70


6. 70-6     =64


7. 64-6     =58


8. 58-6     =52


9. 52-6     =46


10. 46-6     =40%

In a real race the wear would be slightly less thus allowing 1-2 extra laps within the 40% threshold.
 
Sorry, or was all this implied?.

Well I guess we disagree about that. I still find it a viable strategy and use it myself. Can't say it doesn't work.

But you're right that tyre wear doesn't decrease linear. Still this equation makes sense about how many laps you can do on a specific tyre.

I do the same calculations: 6% after one lap equals 100 / 6= 16,7 laps. BUT, I know after 16 laps, the Tyre is not at 0%. It is at about 30%! That's exactly the point I want to ride the Tyre. That's the point of this rule of thumb calculation.

Riding your tires down to 30% or lower hinders your fuel load. How do you make this work effectively Cole? I get the different track characteristics and weather factors. the cooler the temp, the better/longer your tires perform/last...  

You don't have to always use maximum stint length. It depends how long your league races are and how many stints most of the managers do. This is just an equation of how many laps you could do. Since Rafael said he did 28 laps on softs, which is obviously too much, both in tyre wear and fuel load. That's what I tried to explain to him in my first answer.

Of course there is always the act of balancing how many laps you do and how much more fuel you need to do that. And if that makes you slower or faster over the whole race distance. But you have to find out the best strategy for yourself.

Since you're in a 100% race length league I don't think you need this equation since most of your stints won't require utilising the tyre to 100% (according to practise percentages), except for supersofts.
