Do ya'll think fix a flat will fix a pin hole size hole in my sidewall? I got the 37's on but one of the tires loses about 10 psi per hour. Not much of a hole, completely naked to the human eye. We had to pour soapy water on it to find it. Anyway the tire shop said they would not do a radial patch but I should try a couple cans of fix a flat.. any advice? BTW... here is a pic of the new tires.
