This may have been discussed before but have been monitoring a slow leak in my right front tire, finally got the wheel off the car and did an inspection thinking I would find a nail or screw, but found a small hair line crack on the inside of the rim and on the outside flat portion toward where the tire seats. Bubbles coming out when I did a suds test. I assume this means a new wheel, do not think these can be repaired. Input would be appreciated.
