I use google translate, sorry.
I did some tire test on career practice, 100% race.
1st setup to minimize tire wear:
Code:Aerodynamics Front Wing Angle: 1 Rear Wing Angle: 1 Braking Balance: F 50% - R 50% Balance Front Anti-Roll Bar: 1 Rear Anti-Roll Bar: 1 Suspension Front Ride Height: 6 Ride Height: 6 Front Spring Stiffness: 1 Rear Spring Stiffness: 1 Gearbox default Engine Fuel Map: min Alignment Camber Front: full right Camber Rear: full right Toe Front: def Toe Rear: def
2nd setup to maximize tire wear
Soft tires for both.Code:Aerodynamics Front Wing Angle: 11 Rear Wing Angle: 11 Braking Balance: F 50% - R 50% Balance Front Anti-Roll Bar: 11 Rear Anti-Roll Bar: 11 Suspension Front Ride Height: 6 Ride Height: 6 Front Spring Stiffness: 11 Rear Spring Stiffness: 11 Gearbox default Engine Fuel Map: min Alignment Camber Front: full left Camber Rear: full left Toe Front: def Toe Rear: def
And after full 10 laps + 1 to go in box tire condition is:
1st setup: 35%
2nd setup: 33%
There is no difference. So, what is the point of sacrifice speed for reduce tire wear, if it no really "reduce"?
What really matters is how comfortable you are with a particular setup on a particular circuit. If the stiff setup is faster in Quali but you are always making mistakes causing you to lose time in the race than it's no good. focus on which setup will make you most consistent and that will help much more than anything else
