How much psi should I have in my tires?

[BoneStock]

I never really messed with the tire pressure after the dealership. I tested the air the other day and it had 30 psi. The tire says max press is 40 psi. Am I suppose to put in 10 more psi? Help.

I believe 32psi is the recommended pressure. you can confirm this by looking at the sticker on your b pillar

The recommended psi is stated both in the car's manual and along the sill of the driver's door. You should follow the recommended pressure. On the Civic sedan, the recommended tire pressure is 32 psi. Never use tire's maximum pressure (unless it's lower than the car manufacturer's recommended pressure) and never go below the recommended pressure stated by your vehicle. This is assuming that you are using the car's recommended tire size for the stock wheels.

doesnt matter with the series, applies to all rubber

Yup, the recommended pressure should apply to all tires. There are certain cases where you will want to either lower or add pressure to your tires, but if you partake in those certain activities, then you already know how much to add or reduce.

If you have low profile tires (i.e. 40 series, etc.) then remember to check your tire pressure with a tire pressure gauge more often. It's harder to tell if your slim tires are below pressure simply by looking at them or by doing the old (and very inaccurate) tire kick test.

And btw, go by the auto parts store and buy yourself a tire pressure gauge if you haven't already done so. They'll run you a few bucks, but are much more accurate than the tire pressure gauge attached at the end of the air nozzle at the gas station. Forget about the digital gauges...not worth the extra $20 to $60. Get the analog kind...you won't have to ever worry if the batteries run out on analog gauges.

Right on the money. Also, check your air pressure before you drive in the morning when the air in the tires and the ambient temperature is cooler. If you check it at 5 or 6 in the afternoon after a spirited drive home in 97 degree temps, your pressure could be as much as 3-4 pounds off.

There a sticker (instruction for tire pressure) right next to your front door near the middle section of the car. When you open the door look left of it. ( crap for a sorry description)

The All Season tires on my Si recommends 32 front and 29 rears. I keep mine at 36 and 33 (better gas mileage, but rougher ride).

I really like the kind with a dial, they are more accurate than the ones that are shaped like a pen, but they usually run a few bucks more

all jap cars said they run 7psi. so when i race i make sure they are around that. you can tell the car has more acceleration this way because you can barely keep it on the road.

i use a bicycle pump to put them back to proper inflation. no gauge needed.....36.75 pumps looks and feels good.

Sonitex runs the same tire pressures as I do. Ride has been stiff regardless of tire pressure.

Oh...but I have a digital one with a glass breaking hammer, led light, and seat belt cutter...you know, just in case I drive my car into a lake and the windows or door won't open, and the seatbelt gets caught.
