If I recall Kastner's remarks on tires (regarding SCCA racing), it went
something like: "Pump them up to about 40-45 psi cold. If they feel too loose,
you aren't going fast enough." <g> I suppose the general wisdom is that the
faster one goes, the more cornering force there is, and all the tire has to
resist that cornering force is sidewall flexure, or to slip. More air would put
more pressure on the bead, holding it in place more firmly, which is a necessity
in hard cornering, but increased pressure also must have something to do with
flexure of the tire during cornering.
Cheers.
