boat trailer tires?

This may be a bit off topic, but have you thought of using Nitrogen to fill the tires. There is no moisture in it, so no expanding and contracting - they stay the same PSI no matter what the temp is. I have never done it, but I know several that swear by it, especially with heavier boats.

Nitrogen may be OK, but I have heard it costs $35 to $40 a tire. Hmmmm....thats a lot of gas in my tank with a tandem trailer !
35 x 4 = $140
