I have a 2004 SC430, I have replaced the wheel, valve stem, and had two TPI sensors replaced. LF tire still loses air within a week. Two different tire stores can find no leak, no cracks. Any ideas?
only thing you can try is submerging tire and try to keep it under for a while your bound to see air bubble somewhere or spray really soapy water on tire and with patience if it is really slow you should see it foam ever so slightly hope that helps
