Default Correct tire pressure for L Series?

Since we've had a lot of discussion lately about tires and tire life, what pressure do you set your tires? I've heard a lot of different things:

Covert Saturn of Austin says 24 on the front, 29 on the rear
Cavender Saturn of San Antonio says 30, front and rear
Wal Mart says 32, front and rear
Discount Tire says 36 front, 39 rear
The car's label says 30 front and rear

I run mine at 30, front and rear, but suspension / alignment problems keep causing trouble. Should I keep them at 30, or is there a better PSI? I have a 2002 LW200, with 195/65-15.

REWARD EXCELLENCE!

Best bet is to go by the car label. I stick to 32 f/r as recommended by the local place that I get tires from. But discount tire's reccomendation of 36f /39r? That's too much, and the first dealer's reccomendation I think is too low. But like I said, your best bet is to go by the vehicle's label.

Default Re: Correct tire pressure for L Series?

Well, yes and no. You didn't tell us what your goals are.
Correct tire pressure for all around handling and longest life is 30/30.
If you want to get the best gas milage it's whatever the maximum rating on the tire is, that'll bulge the center of the tire a bit and reduce rolling resistance but wear out the middle of the tire faster.
If you want to improve off the line handling (faster acceleration in a straight line) but cornering suffers a little, I'd go with 26f/34r.
With the V6 wagon and sport suspension for best handling with minimul reduction in tire life, I like 33f/30r.
Finally, having said all that, different tires react differently and require "adjusting" the pressure some too. For example, the Affinities have crappy, hard sidewall composition and need to be run a little lower to compensate for the hard sidewall.

My 2000 LS2 doesn't actually have a label or anything specifically stated in the manual. Go figure. When I called the Saturn plant, they specified 32 PSI cold, both front and back.

Jay;

The tire info label on LS2 should be on rear edge of driver's side rear door.The inflation specs are 30 PSI front and rear for 195/65/15 as well as 205/65/15 tires.This is "cold".

The tire info is also on page 384 of 2000 Owner's Handbook. Check table of contents page in your Handbook and look at small print at bottom of page to make sure you have second edition.The first edition that came with early 2000 LS2s(like mine) was full of errors,duplicated and missing pages,etc.

I kept tires at 30 PSI,winter and summer and never had a problem for 4 years I had LS2. About 3/4 of my driving is on highways at 70 mph average.I rotate tires twice a year and have alignment checked every two years,regardless of the car I drive.

REWARD EXCELLENCE!
