[03 Outback tires will not hold air]

Ok, that is the answer I was hoping you would give so I could give you my opinion If you are taking pressure readings at random samples, this might effect your readings. Assuming you know nothing, I will describe what MIGHT be happening. As you drive friction in your tires is transfered into heat energy. As the air gets heated, it gets excited and tends to "bounce" around more than say, cold air. This excited air in your tires will cause your readings to be higher after driving than it was before it left the driveway after sitting all night.

 

I would suggest you take a reading tomorrow morning (Wednesday) and then another one on Thursday AM, and one more on Friday AM and see if there is a constant decrease in pressure or it remains pretty constant.

 

Good luck

Ok, thanks for the reply and the suggestion, I will

There was a recall on the following for some outbacks!

 

"September 2002 2003 Outback 6cylinders Alloy Wheels off center. Some 6cylinder Outbacks might have improperly manufactured, off -center alloy wheels. They will be replaced."

 

Maybe this could be the issue?????

How do I find out if my tires are alloy wheels? And if they are, how do I convince the dealer that they need to replace them?

 

Thanks for the reply and the info!!!

Check the valve stems, it almost seems that would have been checked and changed with the new tires. It almost seems, that with 2 different sets of tires on the rims, there may be a rim defect. I know most, if not all tire places, clean and seal the rims along with replacing the valve stems.

 

Have you consulted a dealer to check about a porus set of rims ???

 

Keep us posted...

The tire place said they clean the rims and replace the valves as a matter of course, but that they would be happy to check both at no charge to be sure, so I will take it in to them, then pursue it with Subaru. What are porus rims?

 

thanks for the reply

[03 Outback tires will not hold air]

when are you taking the pressure readings? in the morning after sitting all night or after driving a lot or a mix of both?

It seems to be a mix of both.

[03 Outback tires will not hold air]

the rims should be cleaned before installing new tires.

 

were the valve stems replaced with the tires? they can leak as well.

bead or valve stem, that's where you loose air.

 

did it just happen once or more often? if they filled it with warm air and you drove the car outside where it's 15 degrees, the air will become more dense and less pressure. remember that PV=nRT jazz. it Temperature goes down, the pressure must go down for constant volume.

if it happened more than once, then you have a leak.

I just checked with the tire place and they said as a matter of habit they clean the rims and replace the valves; however, they also said that I could bring the car in and they would check to make sure, no charge. So I will get back with you. THanks for the reply.

[03 Outback tires will not hold air]

you replaced the tires with new???

Yes.

has the car ever met with a curb? snow bank? anything?

No, it hasn't hit anything. Yet. Looking for some wood to knock on!

[03 Outback tires will not hold air]

I have an 03 Outback, bought it new, and the tires will not hold air. Does anyone else have this problem? Or know what I can do to solve it? I have replaced the tires, but they still leak, sometimes as much as 5-8 pounds/week.
