I have a slime tire pressure gauge and my light came on so I checked my tires. Some how my rear right tire was at about 29PSI according to my gauge. I went to an air pump at the gas station and that gauge said I was at 35PSI. Which one should I trust?

Another note, what PSI should I have my tires for good traction and MPG?

 

Don't trust the gas station air gauge. Get yourself a good air gauge and keep it in the glove box.

 

Get a good gauge .... I use an Autometer 2343 (about $24 from Amazon). Very accurate, very repeatable and it leaves no doubt as to what pressure is in your tire. Forget the crappy $1 or $2 pencil gauges, they are crap.

 

Yeah I figured I shouldn't trust a gas station gauge. The slime one I have was like $2.50. I'll definitely get another one. Thanks guys!

So what PSI should I be at?

 

Well it should be at 38 psi in the rear for the light to go if i remember rite. Just look on your driver side door for the pressure.

 

its by your door

 

thats normal, when you start driving the car the air inside the tire get hot so it shows more, the best thing is to get a portable air pump and check and fill you tires up in the morning b4 you drive on them

 

Correct. 35psi front, 38psi rear.

I saw that and I filled them up to that but I remember reading how different pressures are better for performance and stuff.

 

Do you have aftermarket wheels? Maybe the tpsi are set to be different from stock wheels and tires...

 

35psi front and 38psi rear.
Get the digital Slime gauge.. mines works great
