the old formula for speed at which a tire will begin to hydroplane is nine times the square root of your tire pressure. That is for non steel belted tires, but what it means is if you don't want to hydroplane go slower. Also our wide tires have more lifting area so you will hydroplane much more efficiently... that's usually not a good thing on the highway.

Do the math, 60 miles per hour and you are a hovercraft in most cars.

(disclaimer, that formula is for old school balloon tires, and is not accurate for modern tires, but the numbers are still close unless you have a specifically designed water tread like aqua-tread)
