Tires hot and smoking

I’m not due to move until April 15th for summarization, so won’t know if it was the fix. I inflated to the Thor specifications on the door jam of the cab. 95 front 110 back.

We’ll it’s a lot low, but I’d actually be surprised if it’s low enough to make a tire smoking hot. Lacking any other clues I think I’d air up to spec and try driving a bit to see if happens again.

Make sure your knees are not in the bounce back area

You should use your infrared temperature gun and verify axle, drum, wheel and tire temps next outing

Drivers and passengers should be similar factoing in sun exposure

Also verify your pressure gauge

Are you certain it's a burnt rubber smell? Have you checked to see if a brake caliper might be stuck - dragging on the rotor? That could cause a tire to heat from road friction. And if your wheels are substantially large "heat sinks", they may not be as hot as you might think. Also, if the E-brake was set all that time, it could be the culprit.

I do set the ebrake when I use it. It’s a norm since you now have to have the brake set to open the slide.

If it was the brake wouldn’t the hubs and rims be hot to the touch?

Me either, I should have asked. It has everything else, including lane assist notification.

I have a 2021 E450 and the TPMS is buried in the menu. Check Driver Assist and then Maintenance monitor to see if it's in there.

I will look for it. Not the most user friendly setup.

I use a laser temperature measurement tool from Harbor Freight. I go around and check the tires and rim temperatures on every stop. I do have TPMS as well. If the tires were smoking, I would not trust them. High temps will weaken the tire structure. Tires are cheep compared to blowout damage. Get your rig weighed fully loaded at a CAT scale and then use the weight/pressure chart to determine the proper psi. I always add ten psi so that changes in air temp and altitude does not require me to adjust the psi of the tires. Always set the tire pressure at the coldest temps prior to the sun hitting the tires.

Not necessarily. I don't know about your chassis but the F53 chassis has the EB on the output of the transmission.

You should use the tire pressure posted on the door jamb. Low tire pressure will cause them to overheat and eventually blow.

HOLY SHIT!!!!!!! Did you charge them RENT??????????

[lwmcguire]

I have never actually seen a RV dealer checking tire psig

Surely some do

[Pete'sMH]

Perhaps they check before first delivery - although I’d not want to bet on it - but I’d be very surprised if any checked on a customer’s unit unless it was brought in for tire issues. They won’t check your oil or charge your batteries either.

I have a 2016 35SK on the F550 chassis. I run 85 in the rears and 75 in the front, based on scaled weight and tire manufacturers chart.

I had a wheel bearing issue that overheated the brakes and tires on the right rear. After self diagnosing the issue and spending about $800, a friend of mine found the bearing issue. Sometimes the obvious answer isn't the answer.

[lwmcguire]

A brake dragging will sure heat up a tire and wheel

Infrared temp gun is a cheap diagnostic tool
