I have 19 inch PIAA superrozza's with P-Zero Rossos in the front.
This is the 3rd time I've taken it to the shop. First both fron wheels were leaking air and were getting to lower psi within days. They managed to fix one by buffing the side of the tire and putting sealant while gluing it to the rim.
Last 2 times only the driver side is losing air slowly, was at 32 psi on friday now at 21 psi on monday. Last time they buffed the lip of the tire so it would be a better fit with the wheel and sealed it as well.
They say the tires are fine and the valves are fine as well.
what could the problem be?

They did the soap thing and did the water tub, couldn't find a leak. Maybe it's when I'm at high speeds or when it gets colder or something. Beats me.

If its not the valve stem, and it passes a water test, then your rim is bent. A bent rim can cause an undetectable slow leak. They have this red goo they can line the tire with when they put it on rim that will stop the slow leak from a tweaked/bent rim. It's nasty stuff though, once you put it on its nasty getting it off the rim when its time for new tires. I would suggest buying a new rim if that is the case.
