I had something very similar happen to me last year, and I chose to leave everything alone and run it as-is. Then all of a sudden, 8 months later, I ran over a broken pair of scissors in the roadway and ruined a tire.
Take from that what you want, but if it were me, I'd drain that puppy and I mean FAST!!
