tire pressure front/rear

How important is it to have the rear tires @ 28lbs versus the fronts @ 32? I realize these may not be exact specs, but I'm really asking about the suggested differences between front and rear. Is it Ok to just have 'em all at 32?

The plaque lists 33 front 29 rear, on my car. The weight of the engine coupled with the weight of the front diff, with the addition of the 90-10 split (basically FWD most of the time) is the reason for the front tires carrying more pressure. Mine rides a little harsh when I have all wheels at 33, so, I stick with suggested pressures.

Yes. What's max pressure on those? Dang! If you keep running them at that pressure, you're going to see the tread begin to disappear right down the center. Better bring them back down to the realm of reality. Maybe all at 33, if you feel the need to have them all at the same pressure. I'll almost guarantee you'll notice a "softer" ride.

Jeez, Just follow what's on the doorjamb plaque unless you ride with a different section series, wheel diam. or want to autocross. Jump the pressures by a few pounds equally front and rear if you like. Remember these are "cold" pressures". Your skins will thank you. Balance is everything. B.

The max pressure on them is 44 psi, and at 33, I was noticing my car jiggle like jello at 80 doing a quick lane change. They suggested 38, now that I look...38. So, put them back down?

Significant Technical Input
As long as they're not showing any bad wear patterns just stay below the tire's recommended max inflation and above the door jamb recommendation. If they begin to show wear in the center, drop a few pounds, conversely add a few if wearing on both inside and outside edges.

got it. thanks.

I notice almost no wear in 3,000 miles. I love these tires. All season, cheap ($100/each) stick to the road like glue, matches stock size for the rim perfectly, have a 40,000 mile treadwear warranty, and don't hydroplane at 100 MPH in curves on a rainy day. No exageration, just plain stupidity.
