What is the proper tire pressure for a 1991 Honda Civic?

Answer 1

It depends on a lot of things... Sometimes, there is a sticker on the inside of the driver's door (when you open the door, it should be near the latch)... This will give you a front and back pressure recommendation. A good rule of thumb is 35 PSI. I used to work in a tire shop and we filled everything to 35 PSI unless the customer had a large truck with 8 ply tires (don't worry, you don't have this on your Civic) or unless they asked for us to put in a different amount of air. Anywhere between 25 and 40 and you are safe. Less equals better traction, but lower MPG. The higher the PSI the less traction, but you'll get higher MPG... I'm not sure that it makes too much difference... I would think 1-2 mpg difference between 25 and 40. I'm also not sure the difference in traction would be noticeable. Also, be sure to to over inflate the tire (+50 psi) or under inflate the tire (less than 20 PSI)... These pressures are too extreme and can cause the tire to wear improperly.
