Tire and fuel consumption

I want to create an offline championship where everyone has the obligation to refuel and change tires once. The races lasted an hour. Does anyone know how much I should wear for tire wear and fuel consumption?

 

It depends on the cars, but you could try a mandatory pit stop with 1x tyre wear and 2x fuel usage.

 

Multiclass race, whith P1, P2 and GT

 

You will just have to experiment and see what works. From my experience getting both tyre and fuel to work well is difficult as AI calculates fuel at a different rate to the player.

I'd just forget the fuel and stick a to a mandatory tyre stop with 90 seconds duration, cars in the pits for a decent time but no fuel to go wrong....

 

Good ideia, this is better
