Ok, just putting on winter tires and it appears that ONE of the bolts on a 5 bolt pattern front wheel won't go in.

Closer examination reveals that the bolt hole is stripped.

Question is:

* Right now it's hanging on by 4 bolts out of 5. Seems pretty secure. Is this ok?

* Can I rethread the bolt hole ? If so, what tool do I need to rethread it? (Specifics please on the size/spec of the die/tap!)

This is on the ML...

Thanks for any advice.
