So
Was wondering what others do during a cold snap (5-20 F) and now my sensors are wanting me to add air. But i know as soon as its back into the 30-40 the warning will shut off and if i add air the tire pressure will be to high.

To add or not to add???

Thanks...

 

this is called maintaining your tire pressure.

as you know, for every 10 degrees the temps drop the tire pressure drops 1psi.
same concept when the temps rise.

I run strict summer tires all year long. It's very important for me to keep an eye on tire pressure.

if the tire pressure gets below 37psi, my tires dont have traction.
if my tire pressure goes beyond 37psi, my tires lose traction.

I have to maintain them religiously.
by controlling the air pressure, you can control tire wear.
under inflation causes funny tire wear.
over inflation causes funny tire wear.

if it were my car, I would add pressure in the morning and deflate acouple psi in the afternoon, or when temps get back into the 30s and 40s

 

Wow, add air in the morning and take it out in the afternoon??
God love yea....
Way to much work for me.

 

well, in houston, temps drop to low 30s in the morning, by the afternoon its in the 70's.

tires are very important to me, as my summer set cost 800 for all 4.
I can control on how they wear by simply adding air in the morning and letting some out in the afternoon.

plus, the mornings are when I really need my tires to be in good shape. its wet, its cold, I need to be able to stop.
by having the tires at 30psi and letting them warm up to about 35psi, is no bueno....
I will slip and slide every where

 

i always have mine 33 cold and 36 when warmed up.

 

The relationship Justn suggests is approximately correct if you are talking Celsius degrees. But then he goes on to talk Fahrenheit, so his info is debateable. The more accurate connection between temperature and pressure is that pressure of a gas is directly proportional to the Kelvin (also called absolute) temperature.


If you live in a climate like the OP where this issue is common, I think the most practical thing to do is run a little higher pressure in the fall and winter months and keep tabs on the fluctuations via the MID. I really don't think you are increasing your risks significantly if you drive in a sane manner and take it easy when the weather is bad.

 

Actually, delta between 0 and say 40 cold would be about 4 lbs. When heated maybe 5 (it's winter, not like summer), so I adjust about twice a year. Here in DFW, summer have to adjust, though most performance tires max psi now is 44 to 51.

 

That idiot light is there for a reason if it's on put air in the damn tire... and was that really worth asking? it's not going to re-inflate in warm ambient temps as much as it will dissipate in the cold. stretch out some 30 series on the front and add air daily #stancelife #teamvossen #cambercrawler

 

Gotta love this reply haha.

To All: When the hell do i know if a sensor may have gone bad and is showing TPMS all over my MID?? It started to show a lott more when our temperature here in NY dropped down to like 5 degrees.

 

You're still around lol got like 2 and a half years without visiting Acurazine...Gonna ask some advice from you soon since i've lost my touch.

 

spare $1.00 and 10 minutes of your life to fill your tires up to the right spec (which would be 30-32psi cold as recommended by acura). if its too much work for you to be safe while operating a motor vehicle you shouldn't have needed to ask.

The lowest PSI my tires have ever gotten in the cold was 27.. and that still did not prompt me to inflate my tires. I'd assume you've already been running below the recommended PSI for your tires already at 30-40 degrees in order for you to get the prompt to fill your tires

 

Its not the time or the money or me not being safe while driving.
Its about the tires being at 30 psi at 25-30 degrees and when its -4 or -5 at night/ in the morning when im leaving for work and the sensors trip on because the tires are down to 25-26 psi. If i add air to get them up to 30 in the morning they would be like 38+ in the afternoon which is NG for the tires.
All i was wondering was if other people had this problem. I have had other cars with the sensors and never had the problem. Didnt really want to hear all the DB comments.. thanks
