tire temperature
#1
Hello

I remember that in some converted tracks sometimes a couple of tires don't get warm enough.

I remember there was a solution to this problem by editing the track.txt file

But I don't remember what part of the file to change. Please, can you tell me?

I searched the forum but couldn't find anything (I tried: tire heat, heat, tire)

In Pocono is impossible drive the full lenght by the tire heat...It´s very useful this editing...

THEAT (Tire Heat)
-----------------------------------------------------------------------------
This keyword has eight parameters. This keyword is only used in IndyCar
Racing II. The eight parameters are grouped into two sets of four values.

The first set specifies the heat generated by the tires under dry
conditions, the second set specifies heat under wet conditions. The values
in each set are for the tire compounds in this order: soft, medium, hard,
rain. I'm not sure how this keyword is used in the game, since I believe
that TCFF and TCFR do the same thing. The fourth value may be for rain
tires.

The next four val

TCFF (Tire Compound Friction Front)
-----------------------------------------------------------------------------
This keyword has eight parameters. This keyword is only used in IndyCar
Racing II. The format for this keyword is the same as that of the THEAT
keyword. I assume these values are for Front tires, but I haven't
experimented to make sure.

The first 3 values refer to left side tire heat, right rear tire
heat, and right front tire heat. Higher values mean that the tires are
more sensitive to heat buildup and heat up quicker. The fourth value might
be for rain tires.

The next four values are assumed to be used for grip although I have not
checked them out.

TCFR (Tire Compound Friction Rear)
-----------------------------------------------------------------------------
This keyword has eight parameters. This keyword is only used in IndyCar
Racing II. The format for this keyword is the same as that of the THEAT
keyword. I assume these values are for Rear tires, but I haven't
experimented to make sure.

TIRES (Tires - Goodyear)
-----------------------------------------------------------------------------
This keyword has seven parameters. This keyword doesn't appear in
IndyCar Racing tracks. This keyword is used to define the characteristics
of Goodyear tires.

The first parameter defines the grip for the left side tires.

The second parameter describes the heat generated by the left side tires.

The third parameter specifies the tread life of the left side tires.

The fourth parameter defines the grip for the right side tires.

The fifth parameter specifies the heat generated by the right side tires.

The sixth parameter specifies the tread life of the right side tires.

I have no idea what the seventh parameter is for.

Increasing the grip values increases the grip of the tires. Increasing
the heat values increases the heat generated by the tires. Increasing
the the tread life values increases the life of the tires. Increasing
grip increases heat and decreases tread life and decreasing grip decreases
heat and increases tread life.

-----------------------------------------------------------------------------
TIRES2 (Tires - Hoosier/Firestone)
-----------------------------------------------------------------------------
This keyword has seven parameters. This keyword doesn't appear in IndyCar
Racing or NASCAR Racing II tracks. This keyword is the same as the TIRES
keyword, except TIRES2 refers to the characteristics of Hoosier tires in
NASCAR Racing, and for Firestone tires in IndyCar Racing II.

thanks for the informations

What I can also remember now is that it was a parttern of values for THEAT on oval tracks, created or converted tracks

I remember using it for Fontana and Homestead (the version which is like milwaukee)

I won't change anything for the original tracks, since it would be a cheat

What I found out recently is that reducing the tire pressure in some tracks is very good for gripping

I used to have the default values, which are 39, 36.....Now i'm using between 33 and 36

I think as a first try you might just copy the THEAT values from an original Papy track, which is similar to the one in question.

As for tyre pressure, lowering it indeed adds extra grip, while increasing it means bigger top speed. For example I remember running 45 (tha maximum value) in Talladega, you do not need much grip because of the high banking. Although it gave uneven tyre temperatures, it was still the fastest setup.

thanks for the input

by the way, do you know what happened to the oval tracks in the archives section of the website?

The new archive site is still under construction, you can reach the old one at the link on the top of the new site (just left to the Search button, at least in my browser). Its oval section works, at least for me at this moment it does so Smiley .

yes, thanks, I found it

Fontana is not there. I think I got it from another website, just can't remember which one

As I could remember a little bit more about the tire temperature on some oval tracks, I think the real problem was a super heat and not the lack of heat hehe.

I'm a bit confused, I'll just realize it better playing in some tracks

Lately I have been experimenting raising the value of THEAT so that the tires could take less abuse and will overheat sooner causing handling problems. Maybe I don't drive hard enough, but it seems like over a 40-gallon session that the tires do not seem to lose grip. I watch CART (indycar) races from 1980's and 90's extensively, and it seems like this is one thing you frequently see/hear about which I think does not happen enough in the game.

My modifications are really only meant to increase the reality of the game, not "cheat".

What are your lapspeeds on which tracks? I have run in IIRS for 12 years and tirestrategy and fuelstrategy were essentially two sides of the same coin to have a good result. Tire grip was a tricky thing at some high speed tracks.
