hey my low tire pressure warning came on in my car and i filled up the tires with more air but it wont turn back off what could it be ? i also have aftermarket wheels on it if that makes a difference

 

Did the tire shop that mounted the wheels and tires re-install the Tire Pressure Sensors? If they didn't do that then thats the reason you're getting the warning light.

 

my wheels were mounted like 2 monthsago and now the light just came on

 

fill it back up to 35 (or whatever is recommended for yours) and drive around for a bit... it should turn off after a while.

 

When I got my Winnings, I opted not to have the TPS units installed. After driving some 40 miles the tire pressure warning light will enunciate. However, my light goes off after I shut the car down and will only come on again after driving 40 miles.

 

Mine does the same exact thing. Hey blackg3507, make sure you check your tire pressure again..just because the light came on doesn't mean you are low in air.

 

mine blinks for a minute when I start the car. then goes solid when after that. I don't even notice it now.

 

yep mine does the samee thing

 

cold weather it comes on

 

ok thanks a lot guys!

 

REEL COLD WEATHER IN FLA (40ish) MAKES THE LIGHT COME ON....ACOUPLE OF DAYS LATER IT GOS OFF...EVEN W/FACTORY 19'S

 

yeah that can make it turn on... it will turn off when its warner

 

lol @ cold being 40ish. Thats spring weather over here in Chicago

 

it seems to me the the nitrogen filled tires are great for a few months.then all 4 tires seem to loose 2-2.5 lbs.all at once..i check the psi every 2 weeks..but everytime i put air in them it takes a cople of days of city driving or 50 miles on h-way to get the light to go out...does the larger nitrogen particles of air react different in the cold??the hot weather does not seem to effect the nitrogen pressure much

 

The only reason cold weather makes it turn on is because your tires are probably at a lower than they should be and the cold is magnifying that by dropping the pressure even more do to compression of the air molecules in the cold. The cold weather causes the tire pressure to drop(when the tires are cold) and then the TPS senses that the pressure is below 28 PSI and sends off the warning light. The light can also come on if your tires are all above 28 PSI but one tire(or several) is set at a PSI that is significantly different from the other tires. I don't know the exact number of PSI difference that you have to have in order for this to happen, but I've had it happen to me before when one tire was at 32 PSI while the rest were at 38/39.
