tires pressure light came on this morning. i jus bought this car last week. wats wrong wit it?

 

prolly low
just check it if its around 35 ur good.

 

maybe cuz i saw 1 tire looks little lost air. thanks

 

Cold weather recently?? that may have affected it. Just check and make sure all tires are around 35-37psi when cold.

 

The dealer filled my tires with nitrogen. Supposedly they never get low.

 

^not true, mine are as well. They can still leak air they just don't have the psi swing like regular air does (as much anyway).

 

the owner manual said 32 psi all around. but 35?

 

I always go by what the tires say. With that my tires say 51 max psi so I usually do 5 below, around 45 without any problems ever. Did this with my previous cars as well and no issues with wear. Some will say that's too high but I go with what I've done in the past and what's worked for me.

 

I believe right by the driver side door jamb should also have specs for tire pressure?

 

If I recall correctly, it's 35psi for the coupe. And yeah, nitrogen in the tires can slowly leak out, it just does it slower compared to air. Remember, air is 80% nitrogen anyway!

 

Yup, after I made my last post I decided to do a google search and see if there was actually any truth to it. The consensus seems to be that the nitrogen wil still leak out, albeit slower, so its really just a gimmick. Kinda funny too, the last few times I've taken my Audi in for service they tried to convince me to put nitrogen in my tires for the low price of only $600.....glad I always turned it down. Apparently its free at costco and a filling station only charges $10/tire. ****ing thiefs.

 

If you have the stock 19s, they should be 35psi all around, just look at the label on the driver side door sill.

 

Ya my tire pressure light went off too.. I just think its really senstive.. I checked the pressure and it had 32 pounds.. I put 35 in all tires and it went off and hasnt came back..

 

This might have worked for you, but I just wanted to point out that the psi on the tire is the max, nowhere close to the recommendation. That 51psi is basically saying what the limit is before the tire is in danger of failing..
I'd say, always look at the sticker on the drivers side door.
Another point, you could have the same tires on two different cars from the factory and they will have different psi recommendations on the drivers door. This is because every car has different weight and weight distribution.

 

Wow you are always driving on overinflated tires. The tire max is just that max I is up to the carmanufaturer to determin the operating psi of the tire not the tire company. ALWAYS GO BY THE DOOR STICKER. +/- a few PSI depending on passanger load and weather conditions.
