So I am driving home in my awsome car yesterday and I notice that it kinda pulls to the left.  I had a hunch and I checked the tire pressures (in PSI)-

FL-30      FR-31
RL-18      RR-32

Odviously, you can see why.  My question now is-"how did it get that way?".  

I thought about how I use the tires every from home to school to work to home.  I looked at how many turns of every type I take.  One turn stood out.  Turning right out of the schools parking lot.  

This Turn is special, why?  because it is made of a different compound, is a sharp turn, and almost everyday I roast the tires on it.  The combined stress of turning and peeling out has affected the tire pressure with the forces acting on it.

Now the real question-  "How did it get lower?"
I believe that air leaked out of the little thing on the tire, this would create lower volume with a constant area, creating lower pressure.  OR  The tire was streched out from pealing out.  This would create a higher area and a constant volume, creating lower pressure.

Refering to the latter-  Is it possible to strech out a tire from spinning the tires?

Do you have olod expendable rims? if so grab a bunch of red paint and paint a stripe over the tire side that extends on the rim. Now drive around for a few days and loof if the tire changed position relative to the rim. i'd get new ones if the tire moved independently of the rim.

It could be just a Plain old slow puncture ........... check the tyre for nails etc.

or a leaky valve...

We had a simmilar problem on our old probe, it turned out to be a simple problem that happend where the tyre wouldn't correctly seal against the rim, it needed to be over inflated by a couple of PSI let down a little and reinflated a couple of PSI again and left like that till the next time. It solved the problem for us. Just dont over inflate to much, 5psi absolute max.

fill er up and check every day to see if it is dropping or not..

I've got a leaky tire on my lawn mower at work....

fill er up once or twice a week when I mow, then next time when I go to mow it is down around 10lbs again..
