Message	although my contact area grows, it's actually the coefficient of friction that's increased due the the tires' increase in temperature from the lower inflation pressure? As for the front, raising the tire pressure decreases the contact area, but what you're saying is really this also has no effect? The only effect I could see is to help transfer weight to the rear during launch? Worked out some numbers for the Z. 55/45 weight distribution using 3480 lbs. or 1578.5 kg front wheel @ 33 psi: 187.106 cm^2 = 22.5 cm x 8.316 cm front wheel @ 40 psi: 154.35 cm^2 = 22.5 cm x 6.86 cm TT rear wheel @ 36 psi: 140.324 cm^2 = 24.5 cm x 5.727 cm TT rear wheel @ 25 psi: 202.026 cm^2 = 24.5 cm x 8.246 cm NA rear wheel @ 36 psi: 140.324 cm^2 = 22.5 cm x 6.236 cm NA rear wheel @ 25 psi: 202.026 cm^2 = 22.5 cm x 8.98 cm Memeber #124 of Capital Z of Texas and member ZCCA My CarDomain page
