dumb question but my tire pressure card thats suposidly in the glove box is not there, "just got the car" anyone know the approximit tire pressure for an s-14.

 

im gonna guess 32, but i like mine higher

 

right on that sounds about right
well I guess now that they are at 21 PSI i should put some damn air in em, lol

 

does anyone know the calculation on trie pressure and temp. ?

like if it is 80 degrees there is a certain amout of tire pressure to put it.. its weird

 

Here is the information that you need!

 

watch out on that. That is a car for stock rubbers.

each tire likes a different pressure depend on tread.

32 is safe in almost any car tire for daily driving.

when racing i ran 40 front and 38 rear.

 

This is a good thread....it says 29, and says that it depends on the tire width and rim width however.

But then, if you were to ever go to a tire manufacturer, it would say it depends on the car!

Does anyone know how rim/tire width/sidewall thickness influences the "normal/safe" proper air pressure?

 

your supposed to test and inflate your tires when they are cold at about 16-18 degrees celius. is what I haveheard due to the fact that a warm tire will show a much lower psi that it would cold, there fore you may over inflate the tire. so the best time to check would be early in the morning before you start driving. as far as aftermarket rims and tires who knows my buddy is runing bf goodrich sport ta's super low profile on his lancer and he keeps his tires at 23PSI and they grip like a dog trying to hump your leg.

 

Ok guys

I have 18" rims with 245/40's front and 255/35's rear at 29psi with no problems. Dont read too much into it, I have very good grip even when racing evos

 

id be running higher than that if i were you, maybe just my preferance though..more like 35psi

 

if the air pressure is higher, isnt the rolling resistance of the tire lower? (meaning the friction between the tire and the road)

 

32 psi all around is what I set my tires at. It's a pretty safe number.

 

Generally, higher tire pressure=better gas mileage......

I have "How to Make You Car Handle"....it's a really good scientific resource....

The guy says that as far as handling is concerned, underinlfating affects traction more quickly than overinflation.


So if the "ideal pressure" is 32 psi, for example, 28 psi will give worse handling than 36 psi.

 

that is a good point I know that most of the cars in the speed world chalenge which are mostly stock cars with weight reduction and roll cages basically run between 34 and 38 PSI in their tires. soI guess a higher PSI gives better all around traction. mind these are race tires.
