Sigh... everyone seems to think you need to fill tires to what is written on the sidewall. NO! The manufacturer is required by law to put on the MAXIMUM psi the tire can safley run at.... it's not the recomended pressure at all... 30-35max psi is quite enough even for a heavier car like a trep even with 4 fat asses sitting in it!30 it's way low !! You must be having a horrid MPG and tire wear on the edge.
It's a tricky balance you have to get right... to much pressure will reduce tracton and cause you to break loose on acceleration and cornering, you may not notice it but it will affect your times. To little increases rolling resistance and wil adversly affect handeling....what should i put it to when i go to the track?(the front ones?)
Go back and pee on the floor, and when they ask what & why, say I though we had a reciprocal arrangement, you screw with my car, I screw with you place of business.bhs said:Car PSI suggestion: 32 (1999 LHS)
Tire sidewall: 44 (If I remember right)
Actual: 35. I check it weekly and haven't had to add any air to it for at least a month. The only reason I had to previously was because when I took it in for an oil change, they lowered all of my tires to 30 psi for some incomprehensible reason.
Thank you for your enlightening comments, assumptions and as for your information the pressure written on the plaque sucks a## . I have never followed the plaque readings and I never will if they keep suggesting to inflate at 30 Psi. 30 Psi is underinflated and you can see the stress on the tire. Thanks for your suggestions however you might have different driving habits as we all do, and the 37-38 Psi does it for me and have never had any problems, so it's a question of opinion. And also , different makes of tires require different pressures to operate at max performance, maybe the tires that came stock on the car require the pressure indicated on the plaque, but I doubt most of us still have the original tires on their cars so there goes your theory.DJDiggler said:Sigh... everyone seems to think you need to fill tires to what is written on the sidewall.

The psi on the door placard is what you should fill to... possibly a few more if carrying retarded amounts of extra weight.... it's on there because the car was designed specificly for that psi
And don't lower/raise the press if you have larger rims... if it's to rough go back to stock/get better shocks.
Ummm I red your post 4 times and still didn't understand the meaning LOL :rollgrin: And I'm not even buzzin' :fun_08:Mr.Dodge said:wierd... i had factory new tires when i rolled of the lot with 7 miles on the car and it differ from the writing on the door to the side wall... i went with the side wall.. why because its laws of physics... its what pressure your puttin on the tire hints getting a pressure gauge. and applying the pressure to,guess what? the tires specs...
