tire and wheel temperatures

More likely the exhaust in spite of other comments. I have internal sensors on my trailer so they are insensitive to sun and wind effects. And in spite of the distance the ones behind the exhaust are always hotter with the front trailer tire hotter than the rear. But it also depends on which side your exhaust is at, mine is curb side, or with dual exhaust depends on wind direction. When I searched this issue I found one owner that had melted plastic trim at the lower corner of the fiver when towing during a regen cycle. I don't think a 10 degree diff really matters, worst case maybe rotate tires side to side.

Wow. That explanes a lot. Thanks!! My right front trailer tire is always hotter than the other tires. The pressure is also higher. I never thought about the hot exhaust (from ford diesel) as being the problem. I am now sure that it is true. If I had a brain in my head I would have figured it out! When you stand aft of the exhaust it is really hot. During the regen process the exhaust gases get up to 1200 deg F. Once I had a left front trailer blow out.
There must be some way to cool the tire. Put in a vent scoop?
At least it is another thing to think about.

I thought about that years ago, when first learning about tire temps. I thought it would be cool to have a NACA duct in front of the wheel well to suck air in to help cool the tires/hubs. Then the juices got flowing while watching a short-track NASCAR race, where the cars were spraying water into the brake cooling ducts. Why not do something similar with my FW's tires? Every 15 minutes, or so, have a mister turn on and spray directly onto the tires for about a minute. Just plumb into the fresh water tank. Yeah, your wheels would probably look pretty cr@ppy after a while with salts, but you must might save a child, er, TIRE! :-)
