Tire Pressure

[MAC-7]

I keep filling my tires up to 36-38 PSI but over a week or so it keeps dropping down to 31 psi on the drivers side and 32 on the passengers side. Should I be worried or is this nothing to worry about? Is anyone else noticing this?

If I was losing that much air pressure weekly...I'd have my tires checked.

I would get it checked out to be sure.

Temperature will change tire pressure.

If it has been getting cooler outside it may change your tire pressure.

It will be affected more if there is moisture in the tires. Some fill stations fill your tires with moisture. If you notice the nozzle getting wet, your problem getting a lot of water in the tires.

Not that that would cause it to leak, just fluctuate more. If it is constantly going down you may have a slow leak in tire or valvestem. Tires will seep air over time, but it takes longer to do so than a week.

Also I'm sure you just have regular caps, but some caps let air out to a certain PSI. I think those are mostley used for racing though.

The thing is, it never gets below 31 psi. Is there something in the tires to take air from high filled tires and spread it to the low tires? I think BMW or Lexus have somehting like that.

These are my valve stem caps - Camaro Collection Camaro RS Valve Stem Caps

Well our Camaros definitely don't have anything like that. The stock 19" wheels/tires should be at 35 psi while the RS 20" wheels/tires should have 36 psi. I had a tire that kept saying it was losing pressure and the warning light came on below 31 psi so I took it in to the dealership and they fixed it by reseting my TPMS...which took less than 5 minutes.

Ok thanks Envy. I'll give that a try.

pressure changes when you drive. so make sure what your pressure says, is compared when sitting before running.
you may have a leak, or it may just be fluxuating from heat and cool.

Not sure if all camaros are like this, but mine came with nitrogen filled tires....They have been using nitrogen in NASCAR for a while now. If im not mistaken, this is because nitrogen is less affected by temperature change than the air you get from the gas station. I wasnt a tire guy when i worked in NASCAR, but i do know there are a few more other positives with nitro filled tires....anyone care to elaborate on this? i would really like to know the other benefits just for my own knowledge

No effing way BMWs or Lexus do that. You realize all the tires would have to be connected with tubing and a central control center to even out the pressure. Plus the fittings required to stay airtight but still let the wheels rotate... I know H1 hummers have the ability to have the tires inflated from inside the vehicle but a system to even out the pressure... thats new one to me..

Nitrogen in Tires... Is it a Gimmick?

Some dealers put nitrogen in there new cars, most charge a fee for it on somewhere in your paperwork.
