Default Why 35 PSI for Low Tire Pressure?

Greetings all,

I bought a Corolla S a couple of years ago and have all sorts of great things to say about it. Good gas mileage (as long as you don't load it down with 800 pounds of humans as I tried once), rides fairly smooth, quiet, decent acceleration .. and on and on. All that being said, one simple little thing is pushing me away from ever buying another Toyota.

EDIT - 2011 Corolla S - Stock with OEM tires.

Why did they set the low tire pressure monitor to such a high pressure?

The light started coming on within weeks of my purchase and when I first took it to the dealership they told me .. are you ready for this .. that every tire had to be at 35 PSI at cold temp. Now, I have seen a few posts on these forums and others where everyone tells people how to reset this, inflate that, and so on, but the REAL problem here is that 35 PSI is just ridiculous.

1) The door frame states 32 @ cold.
2) The OEM tires state right on them 'Inflate to a MAX of 32 PSI'
3) The owner's manual states 32 PSI max in multiple places.

So every time I take it to Toyota for the free oil change they inflate the tires to 35 PSI. Even though I knew I should not stand for that I let it go since the light does go off.

Here is the problem. I now have two OEM tires going flat on a near continual basis at only 15k miles. I took them both off today and did the old soapy water test. They are leaking major air around the valve stems. BIG SHOCK given that they have been over-inflated for two straight years.

Now, I know how to 'reset' the system, but will that allow me to set it to a more realistic 'number'. In other words, if I set them all to say .. 30 .. and then use the reset, does it actually 'relearn' to use that as the pressure to trigger the warning or does it simply reset the light?

I am interested because I am going to have to either get Toyota to replace these using 'Liability Language' or buy new tires myself. There is not a single light passenger tire on the market that I could find that does not state 32 PSI max, so I fear I will just keep having problems.

The light is a great tool when it is working correctly and setup correctly, but 35 PSI is just stupid. I have been told by two different tire dealerships that it is a known problem with Toyota across multiple models. The second dealership didn't even know I had a Toyota when I called, and they asked 'is it a Toyota?' Wow! He stated they do it to increase gas mileage. I know that over-inflating can help to increase gas mileage, but is an extra MPG or two worth ruining tires far before their time?

Sorry for the length of the post, but I am very frustrated with this as it is absolutely ruining my confidence in Toyota. If I don't get any good responses I will just go back to the old way by disabling that warning and keeping the tires at 32 PSI. I border on near OCD when it comes to checking my tires anyway so it would not be a big thing .. but I would really like my cars features to work correctly. More to the point, I want someone at Toyota to acknowledge that if every printed label and book says 32 PSI and the gauge is not set correctly.

I need help.

Thanks in advance to all who read this and any who have any ideas. 35 PSI is just .. wrong.

Thank you for the replies so far. Sorry for leaving out the year.

2011 Corolla S - Stock, still with OEM tires that specifically state 32 max PSI.

The part I don't get is why the tire, door jam, and manual all state 32 clearly, but on three trips to service department three different people and the service manager have told me 35 minimum for the monitor to clear. And I have tested it and they are right. It only shuts off at 35.

Was hoping there was a way to set it to 32 (or more realistically 30 since it should only come on when tires are low enough to be a concern). I would guess there is a way to do it with a computer change of some sort, but I was hoping there might be a way without spending a bunch of money.

What kind of tires are on the car and what size are they?

Is the size P205/55R-16 and is the tire the Goodyear Eagle RS-A, or the Bridgestone Turanza EL400-2?

I don't understand the problem and this business of clearing the monitor. You can set the tire monitor at any pressure you like. If you want 32 psi, put 32 in the tires, turn the ignition key to one of the on positions, hold the tire monitor button (under the dash) until the tire indicator light blinks 3 times, and you're all set. Now the indicator light will come on when a tire's pressure drops to an unsafe level.

Dunno, mate, but 35psi cold is ridiculous.

Matter of fact, just this morning I went out in 5F weather to find out why my low pressure light has been on. Max tire pressure for my set of Cooper Lifeliners is 40 psi. When I checked them with my brand-new gauge, left front and rear read 26 psi, right rear 20, and right front 24. So, figuring the indication was due to an imbalance of pressures, I pumped the low tires to 26 psi in really, really, really freezing weather. I mean, it was COOOOLD!!!

The light came on again at start, but knowing the temp was so cold, I reasoned that by the time the tires warmed up, so would their air pressure. And I've read that the indicator needed to be reset by pressing a button located somewhere either in the glove compartment or under the steering wheel. Didn't worry about that, though, and decided to take care of resetting the system when I returned home.

After only a few miles of driving, and to my surprise, the TPMS light went out on its own.

I say that if you diligently check your tires' air pressures, and find they are consistently at their proper level day after day, your troubles are with the car's monitoring system.

P.S. For all the attempts by various members from forums far and wide to accurately and with precision explain just where an indicator light reset switch is located, NONE has provided a picture of where it is. Couldn't find one anywhere I looked, but everyone says it's either in the glove compartment or under the steering wheel--SOMEWHERE. Good luck in finding your car's reset switch, if it exists at all. Sure couldn't locate mine. As it happened, I didn't need to find it.

Written data supercedes oral data all the time, every time. My advice: stick to what you read in print; the rest is hearsay.

Ted, that is what I was asking. Does using that reset simply turn the switch off temporaril, aka reset it, or does that effectively reprogram it to use the current tire pressures as the new limit?

Seems I have gotten various answers from a couple of boards, so I just don't know.
