Ok, maybe my reply wasn't all thought out. I maybe a "newbie" in your little club here but, I have plenty of experience from diving my two civics a combined total of 570,000 miles personally. Let's see, how many tires is that?

Anyways, I'd bet that the bars are higher than 2/32nds. Use them as a indicator ("indicator bars") but mostly, go with what feels safe to you. If you are near the bars, be extra carefull in water and stuff. Since you live in New York (I've never been but always see the snow reports)... if you're even concerned about it, Replace the tires. It's not worth the risk to get a few bucks more wear out of them. If you are trying to squeeze a few bucks, put the better ones on the front to clear the path for the rears in the water.

If you're Mr. civic racer and don't know when to let off the gas pedal in water... you beter keep new tires on your car at all times.
