Tire force combining review
One of the things I wanted to do for quite some time has been to compare Beckman pre-combining with the Pacejka curve fit of the Hankook tire.

Caveat: I am using touring.tire data with Pacejka/Hankook combining parameters. Beckman pre-combining depends on max force slip value (Fx, Fy curve shape). So to have a more fair comparison I have to feed Beckman with the Hankook curves, as they differ somewhat from the touring.tire. This will be addressed in a followup post.

Pacejka curve fit ±0°-32° slip angle, 4° steps:

Beckman pre-combining ±0°-32° slip angle, 4° steps:

According to this preliminary comparison (see caveat) Beckman seems to overestimate the longitudinal force component (Fx) with increasing slip, while Pacejka is keeping Fy closer to maximum at lower slip angle values. This means with Pacejka we would have more side grip but less longitudinal grip at small slip angles but overall less grip (particularly in longitudinal direction) at high slip angles (which is probably what we want for aggressive steering, drifting).
