Left front tire heating up

Friends,

I just finished a 3600 mile trip. During the trip, the left front tire on my Silverado toad got hotter than the rest (20 degrees hotter than the rest of the tires). All pressures were good and the tire looks fine visibly.

Guy from work speculated that the exhaust from my DP is heating up the tire. The exhaust is directly in front of that tire so it makes some sense.

Any one else run into this? Is this going to be an issue going forward?

Any chance the brakes are heating up the rotor, etc?

I don't think so. I touched the hub and "spokes" and all are the same temperature (I know better than to touch a hot rotor), but I would expect the entire wheel to heat up if the brake was getting hot enough to affect the TPMS sensor.

The tire itself is quite a bite warmer than the others.

I would bet on the exhaust, can you get an extension that deflects it down or out.

I guess the first thing to do is check the front bumper to see if it is getting hot.

I could change the exhaust configuration or put an air deflector in front of the toad.

My left front tire (actually it's the sensor) is always at least 20 deg warmer due to proximity to exhaust.

It's a very common occurrence that the tire near your exhaust will run hotter.

I think you have the same issue I have.
2013 Silverado,1500 4X4, ext. cab.
I shoot my tires and brakes with a laser temp gauge and the left front runs 20 degrees hotter.
Now the difference. My diesel MH exhaust is on the right. WHAT!!!
Let me know what you find on yours. I am on the road now. Left AZ heading home to MI.

Well mine is a crew cab, but basically the same truck. So if it is not exhaust, then maybe an alignment quirk of the Silverado? Everything I read on line says that tires running 120-150 degrees is not harmful (I think 250 degrees was quoted as too hot), but I wonder if they tire will wear differently?

I also notice that my left front bumper is sooty, so (naturally) the exhaust is depositing on the bumper, but no damage is evident. Is your right front bumper sooty?

My bumper shows no soot. I had the truck aligned last summer and had them put as much tow-in as specs allowed. I had a little trouble with it not tracking straight. The tow-in solved that problem. I now see a little cupping but the tires have 46,000 driving and 10,000 towed.
New tires are going on next week when we get home.

Another data point, i bought an ir thermometer today and stopped and checked the tire temperatures on the way home. All the same.

I am beginning to think the exhaust theory is correct. T55watson maybe you have your tpms sensors on the wrong tires?

Left front tire heating up

It's the exhaust. My right front toad runs warmer. There have been a few threads on this subject, and it's pretty well established. Of course, that doesn't explain t55watson's problem!! 😂
