Tire pressure?

[Sodium Duck]

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.

As I've slowly learned from some real trend setters like Bailout I've been able to increase my MPG from just over 40 MPG to consistently over 50 mpg on nearly every tank with our AT Yaris and enjoy saving money/resources by reducing wear and tear on our vehicle. I also feel much less stress from driving in a very hostile, extremely busy highway environment as my safety level has increased dramatically as well.

It's not like you're getting bad gas mileage, but I'm sure you could reduce the amount of money you spend on gas and maintenance on your vehicle if you ever put some of the ideas put forward by people like Bailout and members at cleanmpg to the test in your own daily life.

Im just stating what I have seen in real life on my own car. You are the one attacking my results saying that they are impossible. BTW, who pays for this Cleanmpg thingy?

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.

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.

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.

[b_hickman11]

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!

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 .

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?

Yeah. Thats why i just stopped responding to his post and future posts. Some people will belive they are right no matter what evidence you bring up to prove they are wrong. And they will try to find a flaw in everything you say to them or use as evidence in order to keep saying they are right. Its just a waste of time those type of poeple can not be reasoned with.

Here are some reputible, reliable sources of information that will tell you all you would ever want and need to know about tires and tire pressure to put this post to rest. If the quotes interest you click on the link to read the complete articles

"Is over-inflation harmful?
Yes. One of the biggest tire maintenance-related myths is that over-inflation is not a problem. Often, even people who understand that under-inflation is a problem are unaware of the harmful effects of over-inflation.

An over-inflated tire rides on just the centre portion of the tread. The smaller contact area means reduced grip on the road leading to a harsh ride, handling issues (such as steering and stopping problems) and increased wear on tires and suspension components.

What should I do if my tires are over-inflated?
If you find that your tires are over-inflated, release air by pushing on the metal stem in the center of the valve, then re-measure the pressure. Never reduce pressure when tires are hot. Wait until they are cold, meaning that your vehicle has been stationary for at least 3 hours or has not been driven more than 2 km."

"Debunking a Mileage Myth: Can You Really "Pump Up" Your Fuel ..."

http://www.tirestamp.com/index.php?o...139&Itemid=177

"Question: Is my tread wear effected by overinflation?

Answer: Overinflation is almost as bad as underinflation. Overinflation is any pressure that exceeds the pressure needed to carry the load by 10% or more. Just as with underinflation, overinflation changes the footprint too. The contact patch actually becomes shorter and narrower. This results in the shoulders of the tire scuffing along while only the center of the tire makes full contact with the road which leads to irregular wear patterns and lost tread mileage. Center rib wear, flaking, chunking, erratic depression wear are commonly observed conditions in addition to overall rapid tread wear. A tire that is overinflated by 20% will lose 10% of its tread mileage. In addition, traction is negatively impacted since the contact patch is much smaller than is optimal. The ride is harsher since the sidewall is much stiffer and handling is different since the footprint has changed. Vehicle suspension and steering system components are also affected by the harsher ride and handling due to over inflation. Overinflated tires are also prone to cuts and snags, impact breaks, and sidewall and crown penetrations affect a vehicle’s handling. "

we've had deer dart out from between homes within city limits during daylight hours . So you can't always be prepared MR.PERFECTO . The deer are running out of habitat and with the warmer climate of recent years there's been a population explotion . Therefore they're more active in the day looking for food . MAYBE YOU SHOULD EXPLAIN THAT TO THE DEER HERE AND EVERYWHERE .
