So I was filling my tires this morning, and some water sprayed out when I pulled off... I know that water can build up in some air compressors, but should I worry about the water in my tires?

 

I always try to blow the compressor hose out until I see the least water vapor. You should be ok. Some people will say that the water will expand when heated after extended highway driving and could cause a blowout. I am not one of those people
