Tire pressure?

[JetfireK]

When the salesman delivered my Yaris to my home he showed me these Green Tire "Caps"(where you put air in the tire ) He said the tires had nitrogen in them! That they would hold the pressure better than air? So far, So good! And I think someone special ordered this car and then rejected it...Thank goodness for unanswered prayers.

I had ordered a "sport" 3 door liftback from a salesman in New Orleans! I waited three months for my Sport Yaris to come in. THEN I LEARNED....Japan does not ship the Sport to America (they could now? but not then-three months ago).

I then ordered my Yaris from Slidell LA and told he salesman to find me the closest car to the Sport; to which he did.
It came with all the airbags/cd player/mp3 ready/Automatic/tinted windows/15" wheels and sporty rims.
I added the GPS/Backup Camera/Viper Alarm/Scan Guage/ lots of trim and if I could find out how to make the GARAGE I once had no this site I would take pictures...I love the color..Meteorite Matellic..I sold my new Lexus to buy this darling car...and the only thing I miss is the cornering lights my Lexus had...Nothing else....

If you know how I can make my Yaris Garage again I sure would appeciate your telling me..

generally i run 5-10 psi under max depending on the tire...keep in mind, the more the pressure the less the contact patch of the tire. while that smaller contact patch means less resistance and therefore better milage, it also hurts your traction if you inflate too far...and thats not so good.

just watch your shift points and keep your foot out of it, these cars can get 40+ mpg in stock form with ease if you take it easy.

BILL , you can't win . I've tried and it gets us and others more rild up . We too keep tires at 34 p.s.i. ( <or> lb. ) and get an overall average of 38 m.p.g.. If they want to speed up earlier wear on their suspensions and put themselves / others at risk that's their decision . Yeh can lead a horse to water , but yeh can't make 'em drink . NEYYYYY .

THERE CAN BE ONLY ONE -- RIGHT ANSWER! YOU MUST ALL FIGHT TO YOUR DEATHS!

Seriously though, why does everyone need to be so right on this? The OP just wanted to know what pressures you run your tires at, not your life story.

Me, I keep 'em at 37psi. Maybe will go up to 40 in the future.

I'll try to be right on everything: Toyota says 32psi, I'll put 32psi in the tires.

They also say 5w-30, so I use 5w-30, etc...

I might start thinking like a rebel next year and switch to 20w-50 (7qts), going down to 11psi, using green coolant, R-12 freon, bias ply tires, ATF in my 5-speed, torque my lugnuts to 200 ft/lbs, do OCI every 20k miles...or not...Toyota was right on all the other specs, don't know why they'd put a tire information label on the car that had inaccurate info on it; they didn't. OP, Toyota says 32psi...believe Toyota, or believe people that decide to nearly double that number

[yarswiss]

Had them at 45 psi for about 6 months, and have now had them at 50psi for the last 4 months. No problems to report, and while I haven't noticed a significant increase in fuel efficiency, my rolling distances have increased when not using gas.

I have actually hit a few curbs and ruts that blew out a set of tires I had before at 32psi, and they didn't show any damage when I hit the same curbs with my current 50psi tires.

Try a panic stop at 70mph, one with 50 or 60psi in the tires, one with 32psi...see if the over-inflated tires do as well in the braking test as they did in the rut test.

I have been involved in 2 personal injuries lawsuits in my life. One has the plaintive and the other has the defendant. From my experience, I certainly wouldn’t put anything past lawyers or insurance companies. Running tires over or under inflated is a persons personal decision, that I respect. However, if I was way out of Toyota guidelines I would not post my PSI on the internet. It could be a decision that would bite me in the ass at a later time. The same goes for oil viscosity.

The way I look at it, if running nearly double the psi in my tires was the new super-magic way to see increased fuel economy, every single car company would have jumped on that free bandwagon years ago. They haven't because they want their customers to have a balance of handling, braking and fuel economy, not tilt the scales totally in favor of a 20% increase of fuel economy for their products.

Did any of these "test" have a deer involved? I almost hit 3 different deer this week...one of which I had to massively slam on the brakes to avoid hitting it. I would assume with double the air pressure(and less road contact) I might would have had a different outcome. Like maybe some back strap for Christmas dinner.

Panic stops do not happen to those that pay attention on the road and plan ahead. This holds true even if your fellow drivers fail to do so. On the few occasions that I have needed to brake any harder than usual I experienced no difficulty whatsoever at 60 PSI.

As for deer, yes, I run into them on the roads here, too. Also coyotes, quail, rabbits and the occasional black bear. I have never had difficulty avoiding them.


All,

There simply is no room in fuel economy discussions for alarmism or "doomism". Please stop with the venom and rhetoric or I will have this thread locked.

Triple what Toyota states for psi, you have all the built-in excuses required. Hope a semi never locks his brakes, smoking all of his trailer tires, like what happened to me last sat.

It's winter now. People drives like idiots in a hurry. Road conditions won't be that great in many areas due to the weather and road treatment (lots of sand on the ground here)

Safety is more important than fuel economy, especially in a small car that already gets 40 mpg anyway

Call up the auto makers with the revolutionary idea of running double the psi, tell them the easy way to increase the fuel economy numbers by 20% ...I'll expect them to slap their foreheads and turn their tires into 60psi basketballs soon as they hang up the phone...NOT!

Aww am I upsetting the baby since his views are the same as mine....awww

What ? PLAN AHEAD ! There's no planning for a deer that decides to bolt out in front or into the side of your vehicle from over an embankment or from thick brush / wooded area . This has to be the dumbest ( ) thing stated on this topic so far .

The real problem here is the deer. If they had more psi in their hooves, they would have better control at full stride and thus be able to avoid traffic much easier.

So your saying you dont have the ability to forsee 5 seconds into the future to make planned decisions accordingly. And I thought i was the only one.

It's called driving slower when you are in a known trouble area. I am surprised that you were not smart enough to figure that out for yourself.

I hope you're never involved in an accident, no matter who's at fault, but if you are I hope you're smart enough (and brave enough) to tell the officer and the adjuster that you run double the psi that Toyota recommends. But what am I thinking, you've already convinced your insurance agent to run double psi to save fuel, like you're doing, yes?
