"...antioxidants from the rubber in the tires will cause a permanent yellow discoloration to any resilient flooring."

This is about the only issue I've had, you can prevent it with black (or dark) tiles under the tires. In all honesty, it isn't an issue that really bothers me.

As far as the liquid between the tile... hmmm... I never really thought of it being an issue. If anything, spills are wiped up quickly (preventing seepage between tiles).

I like my VCT, no matter what Armstrong says.
