Okay, so I've noticed that I'm losing tire pressure in my front left wheel at a rate of almost 8psi per week. It just doesn't seem right. I checked when I got home at it was down to 15psi, I brought it back up to 32, and I'll keep an eye on it.

I also had the wheel off today and checked for nails... no nails in the tread or sidewall, no cracks or bends. I baby the wheels and have never taken a hard hit on them. Any thoughts as to why I'm losing pressure so quickly? The other three are fine.

They're PZero Neros 185/18/35 on TRDs, if it matters.

Thanks in advance.

Have you checked the valve for a leak? I know when I used to adjust my tire pressure weekly, my air hookup was slowly loosening the valve itself. Just my .02. Hope this helps.

P.S. now I have nitrogen filled tires...haven't had pressure issues since filling them.

Okay, how would one go about tightening the valve stem?

Did you try the soapy water test when you had the wheel off? i.e. - Spray spoay water all over and look for bubbles?

I haven't done that... it was getting dark by the time I got home. I'll likely move the wheel to the back... at least the leak won't be on the drive wheel. I'm not really going to have time to deal with it until Thursday, so I'll make due.

So... about that valve tightening... anyone??

Go to any parts store and look for a valve core tool then, you just take the velve cap off and tighten the core a little

Okay, I'll give that a shot. Thanks.

Okay, so the valve core on the problem wheel was super loose... I tightened it back up and brought the pressure back up... I'll keep an eye on it, but I'd like to think that was the problem.

yep thats exactly what happened to me...

Hope you found the problem...It can get aggravating to have a leaky tire...

burstaneurysm

Yea, it certainly is... although, there still seems to be a leak still (albeit, way slower) I might have a shop just remount the tire and either check or replace the stem.
