Tires Dilution Solution? Anti-freeze in tires question

[Maineiac]

So I'm in the middle of loading my rear tires with windshield wiper fluid, and I'm wondering if I should cut it with water.
I'm on the coast of Maine and it never gets to 20 below, but once or twice a winter it will get down to 10 below. However, I'm not on the tractor when it's that chilly.
Should I go 75/25 fluid to water? If I go 50/50, I wonder at what temperature I'd still be safe. At a buck a gallon, I don't want to be wasting money on fluid I don't need.
Thanks, and stay warm!

It's cheap enough to not really need to cut it or dilute it. But likely you can do whatever feels good. /forums/images/graemlins/wink.gif
