Tire heating and cooling

This is just to satisfy my curiosity (and maybe a few others', too), but has anyone ever seen any info on monitored wheel well temperatures and airflow? All these tire threads reminded me of a situation a friend had many years ago on his boat trailer. He went through a number of tires on his trailer in a short time, all blowing out with no warning. He ended up talking to an "old tire guy" at a small shop, and he said that there simply wasn't enough space between the tires and the fenders to allow adequate air circulation. Buddy unbolted the fenders and found there was enough room to allow him to raise them about 2", drill new holes and re-attach them to the trailer. Magically, his tire issues disappeared. I'd love to be able to attach a remote thermometer inside the wheel well to measure air temps and see how much cooling is actually taking place, then put some small scoops on the leading edge to see if it would make a difference. NACA ducts would be more elegant, but not sure how well they'd work and they'd be a lot more hassle to install. Thoughts?
