tire pressure indicator for over inflation?

Does anyone know if the tire pressure indicator will go off for over inflation? did a good deal of high way driving, on snows and the tire indicator came on. after the car sat for a few hours and did the same drive, later at night, the gauge did not come back on. the light blinked than stayed on. based on the book it states to have someone look at it, but since it did not come on again, i was just wondering regarding the tire pressure.

I accidentally over inflated my tires and the tire pressure light does come on and flashes as well. All I did was decrease the pressure to a normal level and the light turned off.

thats weird, I overinflated mine quite a bit (like 8-10psi over) and no lights came on.

I have been running the tires a little higher in pressure, than normal. When i checked the tires the average was just a little bit over 50 lbs. I reduced the cold pressure and I will keep an eye on it.

Yeah, when I had the tire pressure light blink and stay lit I had my tire pressure around 51-52.

Yea the TPMS comes on if the tire is over inflated, comes on over 50psi - 50psi the max inflation psi on most tires

I have winter tires on they are inflated at 36psi. The sticker on the door states front 32psi back 30. Would this little over inflation triger the "flat tire" light?

No, 36 is perfectly fine.

I run my tires 35 to 36 all the time. On track days I run them around 40. Never had a TPMS light come on except for low pressure, usually around 22 IIRC.

Thanks.

 

These are brand new sensors installed in my winter tires by Firestone. So initially there was no indicator on the dashboard. Next morning at start it blinked and than stayed on. It bothered me so I got one of those external sensors on eBay and keep my eyes on the pressure, how ever the light blinks and stays on after start up and short drive.

Makes me wonder why this did not happen when I left Firestone, but since next morning it behaves like that. All tires are above 30PSI. This is on my Subaru Crostrek XV 2013. Any tips?

Maybe Firestone didn't sync the new sensors properly

you guys brought up a good discussion on over-inflating snow tires. I got my 1st set of the Michelin X-Ice XI3 3 winters ago and they always seem "bulgy" and have the look of low air pressure when at 22/33 PSI, so I have been running them about 36-38PSI. They "look" better and I haven't noticed any difference in tread wear, especially in the center of the tires.

What have you guys been seeing and doing?

I had a contract job that was a long distance, so I bought a Chevy Prizm and went through a little phase of making changes to my car and hypermiling. I got bored of the driving techniques real quick (3 weeks).

 

One thing that hypermiling forum recommended right off the bat is to raise your pressure to the maximum sidewall pressure some even advocated for 60psi even if the tires weren't rated for that. I went for the max sidewall pressure which in my case was 51psi. The care rode like shit, but the tire wear didn't noticeable wear out the middle of the tire, if anything the front tires seemed to wear more evenly. I put about 80k miles which most of it was done with elevated tire pressures and I wore out one of set of tires. The car had relatively thin tire (185)mm, so maybe that played a roll. My ex-wife had Toyotay Highland with 225mm width SUV tires and I raised those to 44psi (side wall) and I didn't notice a difference with the tire wear either. The big side wall barely made a difference in the ride quality. I run the factory tire 33/32 pressure in my Legacy, so I can't give you any further experiences.
