I have had an intermittent (sp?) problem... I have come home from work and found the passenger side front tire completely flat on two occasions over the last couple of months?
After I reinflate the tire I soap the stems and no leak
Nothing in the tire that I can see! could it be a very small leak on the rubber valve stem?? should still be able to see bubbles when soaped though??
What are your opinions on changing out the valve stems to the steel ones?
