If, especially in front-wheel drive family sedans such as Accords, Altimas Camrys, Elantras, and Malibus, there is a 55/45 or greater percentage difference in front-rear weight distro, why do car makers recommend the same cold TP all around on the Tire Placards in their vehicles?
IE: In a typical sedan, the placard would read 32psi for all four tires, where 1-2psi more might benefit the front wheels, and 1-2psi less might do, in the rears. IE: Front: 34psi, Rear: 31psi.
Rare is the BMW that doesn't recommend different front and rear cold pressures, and not a few Subaru models: Typically it's the opposite than in only two wheel drivers, with a late model BMW or Subaru recommending 30front and 34rear.
In the former case, is equal pressure specified just to make it easier for the average driver to remember? I know my wife's numbers(30psi all around) and mine(32psi) by heart. But if I think a slight redistribution of the pressures mkght improove the handling, it couldn't hurt to try, right?
