I'm just done a few laps around Sepang in the FIS cars and I'm having a bit of trouble.

The tires aren't TOO hot, but I'm not happy with the temps. Running 105C just seems a tad bit high for average useage.

What IS the best way to lower tire temperatures?
Do I just need to drive more smoothly, and treat the tires? I've heard of adjustments in tire pressure, and adjustments in spring rate.

Surely some of you F1 guys have run into problems with hot tires. What do you do about it?

Thanks

My advice would be to lower tire pressures for a start, thats what i would do in real life so i wouldn't imagine its much different in a sim. Also just try and be extra smooth if you know the car is having issues.

I believe camber can also have a large effect on tire temps, so i guess you could try that too. Depends what tires are heating i guess.

But anyway, im no expert lol so might not be the best advice in the world. Tim's the man to talk too about this :)

The only real way is to ease off them in the corners. You can take your straights as fast as you want, but from your turn-in point to your track-out point, just run a tick or two off to ease off the lateral forces the tires are having to put up with. This will take a few laps to relieve the temps though and will only shoot right back up once you start lapping at full speed again.

Long term solution is to change how you drive. Make sure you are not turning your steering wheel an excessive amount in an attempt to compensate for a bad racing line. Make sure the rears are not slipping/sliding around under acceleration. Etc

Yeah, what Tim said. As you get the track down more and more consistently and get that clean racing line, you will be correcting less which is less scrubbing and you need to concentrate on precise throttle and steering application. Throwing the wheel more than the slip angle might feel normal enough but it creates more scrubbing. So while you might not slow down at all by turning more than you need, it will increase temps and wear slowly but surely. Same with throttle and brake application, just the right amount is ideal; not more.

It should also be pointed out that the Medium compound tyre's optimum temp is in actual fact 105C.

I thought the data file someone quoted in another thread said that optimal temp was around 95C?

Each mod 'MAY' have a different optimum temp. And mods with two or more compounds most likely will have different optimum temps for each compound. Although a 10c difference does seem to be REALLY REALLY large.

You can examine the tbc file for each mod and find the line that controls optimum temp. Use notepad or any other text editor and open up the file in your mod that ends with .tbc.
You may see several different tire files..i.e.
Pirelli.tbc or Michelin.tbc or what-ever the mod calls for.
Open the file and look for the following line:

Temperatures=(106.0, 75.0) // Optimum operating temperature for peak forces (Celsius), starting temperature

The F1 BMW tire this came from has an optimum temp of 106c.
If you look at the rest of the tire file, you MAY find the fronts and rears have different optimum temps and the different compounds also MAY have different temps.
So learning to read the various files can open a lot of information for you. Including such things as the optimum temp for the engine oil.

It really is that high yes Justin. Read it in the HDV or .ini file (I forget which exactly)

In addition to what Dave said, if there are two or more tbc files (eg F1) , the one in use is defined in the hdv file - just search for TireBrand.

Also the confusion above, Andrew & Jon are referring to FIS with 105 deg, F1 is 95 deg as you thought Justin.
