Driving home it popped on.

Less than 3k miles on the tires, I can't see any obvious deflation going on.

Temperature is 20 deg less than it was when i brought the car and it was last reset.

Could that be the issue, or should I be going to the wheel place on the way to work tomorrow morning ?

 

You can't really tell if a tire is underinflated from looking at it. Check the tire pressure at a gas station and reset the gauge.

 

Yeah I'll go out after dinner in the rain and find a local gas station to see.

 

actually I have less than 1.5k on my tires and I had to put air in them the other day.

 

back-left about 10psi low

taking it to the shop tomorrow am to check for holes.

 

hooray for a tire pressure light that does its job! my tires have been keeping its pressure well, both stock and new ones.

 

Interestingly enough, I run different pressures front and rear, and I never see the light come on. It must be fairly clever.

 

29f 32b I think is what's recommended.

No light this morning, so I'm postponing my trip to the wheel man.

Ideally if I go and I need a new tire, I need new rims first, which is a whole new battle.

 

you got it backwards

its 32F 29B

i have the same problem too
Im so wanting some new rims for my tC, and the fact that a tire upgrade is almost necessary........

 

I think if you run more that 32F and 29R the light comes on... even after you reset it.

I added a couple pounds (just a couple) to the front and rear, reset it, and it still comes on after about 5 miles of driving.

Any thoughts

 

well resetting the guage doesn't reset it to the stock psi
it guages it by reading how fast each tire is spinning.
if your overinflating the tire, itis reading that as normal

then maybe the tire is too full and letting the air out somehow
then your light comes on because the tires are not at what it started with.......

??????

 

My new tires stand .200" taller than the OEM rubber, and are inflated to 36F/38R. The tire warning dealy-o can't seem to tell the difference.

 

mine is fine but keeps coming on i think its cause my front under aid dam came off but the tire pressure seems fine

 

Here is a little tid bit I ran across that has helped me.

Running on stock wheels with stock tires Mine came on and caused me to check my tires. They where all fine. I reset the indicator, but it came back on again.

Anyway the short story is it kept coming on even though nothing was wrong.

In researching the issue I discovered that if you clear the indicator, then press and hold the reset switch for 3 seconds the indicator will blink slowly three times. Once this is done the presure sensor will go in to learning mode to recalibrate itself for the next 60 miles or so. During the next 60 miles or so it will not work if one of your tires get low, but once the 60 miles are up and it has complete the recalibaration process it should be back to normal.

This worked for me.

 

good deal cause now that i think about it did recently go from 18s to 17s so that may be y too but ill be sure to do that

 

tap...tap...tap....tap....tap....tap....tap....tap


That's the noise I heard yesterday driving home from work with the window down. So at teh next stop I jump out and feel round my tire and BINGO, nail head smack in the middle of the driver/rear the 'issue' tire. 100yards later is a tire shop, pull in $10, patch job, out less than 30 minutes later (20minutes of that was answering endless mechanics questions about the ride, and wether I thought they should sell their del sol's and buy a TC).

Thank you tire pressure monitor.

 

I didn't know people still charged for flat repair??? Perhaps if its a Mom & Pop location, gotta pay the bills I suppose.

 

Depends on how they're done...
If you do it the "right" way, you dismount the tire from the rim. Patch the hole from the inside. Remount and rebalance.
This can not be free...honestly. Not unless you're a great customer of the shop and they know you well or you've bought tires from them with a warranty which will cover such repairs...
The "not-so" right way would be to pull out the nail and push in a fibrous "plug". Five minute job...cheap? Yes, but not always a reliable repair.
