Front tires lose air when driven hard

[2006WRXTR]

Here's a stange occuring thing.

I drive my car hard, taking turns where I flick the back end out by turning inward quickly. Giving it lots of gas as I come out of the turns. The stock tires are screaming for me to stop; screaming at the same time; but I don't stop. I continue on my merry path, turning here and there at high speeds giving the tires and brakes a workout.

After doing so, my front tires are usually very low on air [under 20psi]. Usually one or the other is low, usually not both. Anyway, I pump them back up; every time thinking that I am going to have to get the tire[s] checked, but after I inflate said tire, the air stays in... no leaks.

Strange.

The tires are the stock Potenzas that come on the 06 WRX. The wheels are Prodrive P1's.

Normal? Abnormal? Is it my kid letting the air out because I did not take him with me? Gremlins?

Sounds to me like your tires are actually rolling off the bead slightly when you are turning really hard. If you have ever seen pictures of cars corning hard the tire can roll under the rim really bad. Try running some more tire pressure, some autoxers can pipe up here for optimum pressure.

pressure will change with temp as well but not 13psi off the stock pressure of 33 psi, if thats what you use?

Check and see if there is peeling on your tires.... That will be a sure sign that you are rolling over on the tires and should increase the tire pressure....
I usually run approx 4-5 psi below the max rating of the tire... If you want comfortable then go 37-38psi front and 34-35psi rear.
At the track I run 40psi up front and 37 in the rear.

why so big of a jump between front tire to rear tire pressure? the "factory" diffrence is only 1psi, but we all no that 9 times out of 10 the "factory" way is not the right way.

^^^^^^it must be different on 06's b/c my 04 it's 32f 29r.

My tires are at 31psi. I will increase the pressure, and run it a bit. I will let you know if anything changes. Thanks everybody.
