Tire Pressure?

What is the recommended tire pressure for a '98 Buick Regal?
According to Tirerack (and assuming you have the original factory tires):
For the 1998 Buick Regal LS, 215/70-15 tires have a maximum inflation pressure of 44 psi.
For the 1998 Buick Regal GS, 225/60-16 tires have a maximum inflation pressure of 49 psi.

Best answer: Addendum: The recommended tire pressure (assuming original factory tires), as le morte stated, is 30 psi for the front and back tires on the 1998 Buick Regal LS. The listing for the factory tire size on Accu-Pressure lists the same size for the LS and GS, which differs from the size listed for the GS on Tirerack. If you have the larger size (225/60-16), the recommended pressure for the larger GS tires may be 35 psi. According to the owner's manual, the Tire-Loading Information label provides correct inflation pressures for your tires when they're cold, and is located on the inside of your trunk lid.

Please note that "maximum inflation pressure" figures are for particular makes of tires. They are the limit to which you can inflate a given make of tire. The max pressure is usually molded into the sidewall.
Max pressure" should not be confused with the car manufacturer's recommended inflation pressure. That figure is determined to be the optimal pressure to provide the correct ride characteristics. In general, one should never inflate their tires to anything near the "maximum inflation pressure."

Normally this information is located either on your driver side door jamb or under the trunk.

I put most tires somewhere between the manu's recommendation and the tire's maximum. Takes some of the 'Buickness' out of the ride.
I bought a VW Jetta from a friend years ago and was puzzled by its crappy gas mileage and spongy ride. Tires were all at 24 psi, pumped them up to 36 and all of a sudden it felt like a small euro sedan rather than a bloated amero one.
Try 36 psi all around and see if your mileage and ride improve.
(this is, of course, assuming you don't want the super-numb ride that is built into a buick)

The correct answer is... none of the above.
The tire pressure listed on the vehicle's placard (and in the owner's manual) should be used as a starting point. What you want to do is maximize and evenly distribute the contact patch (where the rubber meets the road) and to do this requires performing a very simple test.
Search for - tires "chalk test" - and you'll find the procedure. If you do perform the chalk test, I would be amazed if the proper tire pressures for your front and rear tires turned out to be 30 psi!
