“The relative change of the L/D between undeformed and simulated deformed tyres is about 2.4% during straight-line driving and about 2.5% during SLB. The aerodynamic balance during the SLB shows a relative change of 2.3% for this comparison. The increased temperature of the simulated tyres leads to a relative change of 2.5% in downforce and 1.2% in aerodynamic balance to the front during HSC, which might be felt while driving. In comparison to that, the same effect in aerodynamic balance can be achieved by a change of 1-2° in the angle of attack of the front wing flap. The influence on the lap time of the aerodynamic findings reported in this article is 0.22 s.”
