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.

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.
