Thread: Quick question

What is the best pressure # to keep the tires inflated? 17"...

Summer?
Fall?
Winter?
Spring?

Right now all my wheels are between 30 and 31

I keep them at 33psi now. And that should be good year round. But when it snows I lower 2psi

well all season long should be 32 or 33psi...if u have lower then 30 then ur car rolling heavier and u waist more gas..and u feel ur tires more mushy. recommended for all tires on a car is 32.

I heard during summer you should lower it, since the tires get so hot from the road...

and for the winter you should raze it . . .

In summer they do heat up much more but I doubt you'd notice the difference unless you drive like a maniac. Nissan tells you what to run on the tag located on the pillar when you open your driver side front door. Doesn't say anything special for varying weather so I'm sure you'll be okay with constant pressures year round.

i usually do 32psi on my car and on the subbies i work on

Now that makes more sense. . . thank you =]

i usally do 35 psi year round dont no why just like how the car drives like that

go to 33psi, you probably wont feel a difference in the drive and might save 1 MPG

it also depends whats your max psi. some tires hold more then others. commen max psi for 17's are 40 or 45.

I am using stock size tires.... the ones that usually come with 17" wheels

anyway i pumped it up to 33psi all around . . . and i felt a slight difference right away =]
Thanks for all the input guys

/thread

if u want the best MPG inflate to 40 psi, some tires can hold max of 50 psi... at 40 psi u feel more bumps though.. stick with 33-35 and ur good

You are right about feeling more bumps...
When you will lower your car you will SLAMMM your brakes for every little bump (you'll see lol) . . . so I will stick to 33psi for now =]
