THE TIRES ARE GOOD I'VE HAD THEM ROTATED & BALANCED. IT'S NOT ALWAYS THE SAME TIRE BUT MOST TIME ITS ONE OF THE FRONT ONES. I'VE HAD THE VALVE STEMS CHECKED. I'VE TAKEN THE TIRES OFF THE CAR AND TAKEN TO TIRE REPAIR PLACES AGAIN THEY FIND NOTHING WRONG WITH THE TIRE ITSELF. IS THERE SOMETHING WITH THE ALUMINIUM RIMS THAT IS POSSIBLY CAUSING THIS?
WHY DOES MY TIRES GO LOW/FLAT LIKE EVERY OTHER DAY? on 2005 Chevrolet Cavalier
Sorry for the comment, but they have to be leaking from somewhere, maybe air them to the highest pressure you can and have the weight, and submerge in water. Aluminum wheels are not solid and pores.
