Default Quiet Ride

Does anyone know what is the best tire pressure for a smooth ride, 30psi or 28psi. And would a strut brace give a quieter ride going over small bumps and crevaces. The ride seems a bit hard for a car built for luxury.

Being an SSE, my setup is about as hard as it gets for an 87-91, and that'* not hard-riding at all. It'* actually much too soft in my opinion :P Lots of float over highway expansion joints.

The strut brace probably won't help with ride quality, but if you can your hands on one (at a junkyard, from any 1992-1999ish H-body GM), get one. It'll help out your handling quite a bit.

If it'* a softer(smoother?) ride you're after than 28psi is the way to go. Be advised that I would NOT go lower than the recommeded tire pressure listed on the edge of the driver'* door. The shocks/struts/springs you have in your car also affects the ride. And if the ride is too "noisey" for you, you might consider new tires with a coservative(less agressive) tread design.

In my experiece, the strut tower brace actually did improve the ride a lot. My car rattled and flexed horribly when I went over a certain deteriorated expansion joint on the way home from work every day before the STB, but after, it just makes a gentle "thud". Keep in mind, this is Michigan, so you know the road hasn't gotten any better...

And of course, the handling is a bit tighter too.

Whatever you do, and whatever you want your car to be, I would highly recommend doing the STB. The car will just feel better.

Oh, and I say just stick with the suggested PSI on your door. On mine, it'* 30 all around. Anything less and your tires will wear funky and your mileage will be hurting. Also, like the man said, stay away from low profile, stiff sidewall, performance tires.

If all else fails, sell it and buy yourself a Buick Park Avenue.
