Is There A Tire Wear Chart?

[Cornerstrike]

Greetings,

So I know charts exist that show us the BOP updates and changes for group cars that we use on daily races, with gtengine.com being arguably the best.

GT ENG!NE / GT7 / Gr.3 Car Specs

Gran Turismo 7 Database website

gt-engine.com

But within all that data, I failed to see anything in regards to tire wear. Does anybody know of any other chart on any of the website that may contain that information?

I’m very curious to see how the group 3 and group 4 cars compare when it comes to this.

I'm not sure how that would work as tyre wear is very much dependent on how you drive the car.

Heavier cars will tend to wear tyres more though so that will give some idea.

You'll have to use your gut and review races to get a clear idea of this. The closest thing we have are Tidgney's car profiles (playlist).

If you don't have time for all that, spec sheet is probably your best friend here - so I would recommend looking at:

• Downforce + Downforce Distribution
• Weight + Weight Distribution
• Drivetrain Layout
• Power, Power / Torque Curve (and racing RPMs)
• Fuel Load / Efficiency

You would still need to consider the track's characteristics, like the number of corners and the length/angle of them, how often you brake/accelerate, etc.

But otherwise, the data collection process for this would be too impractical/time consuming for something of that scale. For example, my time guesstimate for calculating the optimal strategy in a daily race from test laps alone would be ~2x-3x the length of the race just for a single car/track combo (assuming flawless driving + optimizing data collection). In reality, a bit of time is needed to correct the outliers in the data for each tire, so that might be 1 or 2 extra runs per compound.

You could try to extrapolate from a few lap's data, assuming you can identify a pattern (linear or exponential increase) in the time loss, but less data is less reliable.

Doing that for the entirety of Gr.3/Gr.4 on every track and/or condition is just too much, in my opinion.
