Tire pressure question for my 97 gsx

well the label on the side of my door says 29psi rear and 32psi front? so there lying or what?

The ones on the door is for the factory rims and tires..Go by whats on the tire. 40ish the tires will be hard..Like riding on a gravel road..
 
im running 29 front 32 in back

fyi
 
I always take what's on the tire and lower it. They list the max psi it should be inflated to. Keep in mind, your tire pressure should be checked when the tires are cold (aka haven't been driven in a while - like overnight). This is because pressure rises as they heat up. I typically set mine between 32 and 38psi, depending on what the max rating is on the tires.
 
I don't pay attention to the door labels on any vehicle. If you do, you'll be wearing tires out prematurely on a regular basis as well as getting poor fuel mileage.

Tire technology is constantly changing. Every manufacturer builds their tires differently, and what might've been correct 10 years ago is far from correct now. Run whatever you feel is safe between the door tag pressure and the tire's max safe pressure, and pay close attention to tire wear....if the edges are wearing off of all four tires, your pressure is too low. If you're wearing out the centers only, you need to lower the pressure a bit.
 
I run 36PSI because my in town driving feels easier? doesnt feel so much like a boat. that and i raise my lower timing sliders around 3000rpms for more umph.
 
So for daily driving what do you think I should run in all 4 tires? The max psi is 44 on my tires so should I make them all 35psi or 32psi? We have alot of shitty roads and potholes so I don't want them 2 hard cause it feels like a rock.

The nice thing about tire pressure is it's adjustable. If they're too hard, you let some air out; too soft, add some more.

You can find your own happy medium.

If you let me drive your car for a week, I'll let you know...
 
Not that big of a deal overall, a few psi won't matter. I run my tires around 35 psi on the street, but that can increase as much as 5 psi after a long drive. When I autocross I bump the rears up to about 40, the fronts to 37 as it makes the car handle more neutrally. If the pressure is too low the car will feel wallowy and slow to react, you run the risk of denting a wheel, and you wear the outer edges. To high and the ride will feel harsh and stiff, you will have less traction and will wear the center tread. Sidewall profile and stiffness make a difference too...
 
We have given you plenty of information on how what tire pressure you should run. Pick a pressure and if it doesn't feel right, change it. It's not that hard. I wouldn't suggest trying to run different pressures font/back until you know more.

Oh, and I like how you tried to sneak in street racing again by not typing the word street :toobad:
