I didn't realize how much of a difference makes having your tires inflated properly. I've been riding on my stock wheels for about 2 weeks now, and I didn't know my stock tires where at 22-25 PSI on all 4 corners.
Actually I knew they where low, but was too lazy to put air in them. So finally after the 2 weeks I put air in them to about 35psi. Well the car rides and feels soooo much better. The steering wheel feels a bit tighter, and it handles better. It also feels smooth when cruising at highway speeds

So just a friendly reminder to go check your tires right now

 

Same happened to me, except I was doing a long distance trip and I had to gas up (about a 237 mile trip) and I never had to gas up before (left on a full tank), then I came on here, read the faqs, found out what my tired pressure should be, filled it up, next trip didnt need to gas up, plus the ride was smooth.

 

yep, first i put my pressure to 32 in front and 29 in back as recommended, but tire looks like they are flat and sagging, i have mine at 35 in front and 33 in rear, rides much better, and tire looks properly inflated too.

 

Thanks for the reminder. Why are you riding on your stock wheels?

 

I need to sell them so I can buy some other wheels

Oh yeah and they need 2 tires

 

Looking at lighter rims after the EV-S?

 

Same wheels just 19s instead of 18s

 

I check my tire pressure every week.
I came across this realization a little while back, and just made it a point to do so.
I also check my oil and fluids on a regular weekly basis, just to be safe.
My car is not using oil, but it is a whole lot cheaper and easier to just check every once in a while, than to miss something and have to pay for a whole new motor for some reason.
It is the same way with the tires. It is a whole lot easier to check your tires every once in a while, than to have to replace a tire from riding on them too low.

@ Optimus:
Isn't your car fast with the stock wheels on there?
I bet it flies after having the 18's on for a while.

 

I havent checked mine in a while... been to lazy also

 

I religously check mine. Low profile tires need to be watched. I agree with sunysb83, i put 34 front and 32 rear

 

I run 38 front and 34 rear. My tire pressures almost never change, but I check them frequently. It's very important, the way I drive.

 

36 Psi in the front and 35 in the back.

No matter how much air I add into the front wheel. It still bog down a bit. Either I've been using some cheap tires or my front is too heavy. I check it every week. Talking about oil, I need to check it.

 

The psi on these tires I have right now is really high max.
I keep like 40 psi in there, because it calls for like 51 max psi.

 

what should the PSI be set at front and rear for 225-40-18 low pros? or at least, what do you guys run?

 

Actually to be honest, I don't feel the difference thta much as far as speed. But with my 18s my car handles much better and it brakes better.
I bet is just the tires, but the 18s look so hot

 

Just some things to keep in mind:

1) Radial tires always should look a "little" flat. That's just the nature of them.

2) The PSI listed on a tire is it's MAX psi cold. You never run to run the tire at max PSI cold because as the tire warms up, it will gain 2-6 psi depending on speed and the length of travel. Overinflating a tire can lead to a blow out.

3) Suggested PSI is related to the weight on the tire. Many tires have a max psi of 50-55 psi, but that kind of PSI is more for tires that have a lot of weight riding on them. A Maxima is a relaively light car therefore not a lot of weight is exterted on the tire. At most, each tire is seeing 960lbs to 750lbs therefore all the tire needs about 32-38 psi to perform optimally.

 

yup, it is said that tire pressure goes down about 2-5 psi a month

 

Dave B, you never cease to amaze me with the wealth of knowledge that comes out of your mouth. I mean that. Thanks for the info. I like reading informative posts like that.

@ Optimus, yeah, the 18's look really good on there.

 

ya check your air pressure regularly it's the #1 cause of blow outs. I work for a tire company so i can see what happens 1st hand. specially with low pro's. the vehicle recommended tire PSI is on the door plaque located in the door jam of the drivers side front door. of course everyone will run different PSI according to how you like your car to ride.
