One point to recall on tire pressure, the effects of heating. I run the tires on my electric Civic conversion at about 40 PSI front and 38 PSI rear. The sidewall rating is 44 PSI, factory sticker says 32 Front and 28(?) rear. The thing is the factory rating is for cold pressure and assumes you may be driving at high speed for hours, which would really heat up a tire and raise the pressure. Since my EV is an in town only commuter and seldom exceeds 45 mph, heat buildup and the resulting pressure rise simply never happens. For all intents and purposes my tires stay pretty cold most of the time which is not what the factory expected. Effectively at the factory settings they may be under inflated.
