Front right toad tire runs hotter

2022 Ventana 4334. Rear lower right exhaust.

Iíve noticed the right front tire of my toad runs about 10 - 12 degrees hotter than the others while being towed. Or at least the sensor is 10-12 degrees hotter. Pressures are remaining the same across all 4 tires.

Iím assuming itís the exhaust gases from the tail pipe. Has anyone tried turning the exhaust tip slightly outward to lessen the heat differential or have ideas for another solution? Or do you think itís not worth worrying about?

First check for dragging brake on that wheel, if it is not, then you are safe to assume it is MH exhaust.

Check your Exhaust pipe. Mine was was doing the same. I changed the tip and got a long 90* tip and slightly angled it upwards and it works fine now.

I have the exact same thing going on. 10 degrees is 1 PSI which I often see on the Valor. Still well within acceptable range so I just accept it as normal.

Have you tried swapping sensors to see if itís just an inaccurate sensor?

Me 5 or whatever number we're at. My right front tire on my Ford truck can be 20+ degrees hotter than the other three. The first time it was an issue, was climbing the Baker Grade into Las Vegas, I suddenly got an alarm. I pulled over and realized it was a temp alarm and the tire was fine. I later changed the alarm limit to 145 degrees. We just returned from Zion two weeks ago. It was HOT, 106 degrees in the campground. I found the alarm being triggered again. I bumped it to 145 degrees.

The half round exhaust tip, more of a shield, on my Freightliner chassis, points straight back and down at a slight angle. I tried to turn it to the side a few degrees and it ended up causing the paint in the body cutout to brown, so I turned it back.

With all that said, I doubt that it's actually heating the tire to the higher temps. It's heating the tire more than other three, but the sensor is mounted to the valve stem and is out in the open air. I think the overheating is external to the sensor, not the internal air temp of the tire.

Lastly, adjust your temp limits and don't worry about it.

Easy to test, move the TPMS receiver from the coach to the toad and go for a ride.

Thanks for the post, I've been worrying that something was wrong with my jeep but could never find an issue other than when towing. Now I get it! Thanks again for the simple ease of mind.
