Front Tire Temperature on E450 Freedom Elite 30FE

[RVHopeful]

All,

I am concerned that my front tires are getting to hot.

I have noticed recently that according to my TPMS my front tires are heating up much faster then my rear tires. Last night I picked up my RV from Storage (20 mile drive) and when I got home my Front tire temps were about 135 and the rear was in the 90's. I was towing a 4dr Jeep wrangler if that is relevant.

Tire Pressure is set at 75PSI for the front and 80PSI for the back

The temps have not setup off the TPMS Temperature alarm it just seems they are getting hot fast and it was not sunny.

This particular drive had a lot of starting and stopping for stop lights and never above 45 MPH.

Is there anything I can check to put my mind at ease, does this seem normal.

Thanks

Yes, weigh your RV. See how much weight the front axle is carrying.

A lot of braking will heat up brake rotors and most braking is up front but that does look excessive like front calipers are dragging, did you notice any brake oder.

Feel the doghouse cover inside the coach, doubt you can hold your hand there very long before its uncomfortable. That same heat is sitting between both the front tires so I'd say that's most likely normal for the fronts to be higher.
Are those the recommended pressures on the tag on the rv, if not you may need to go by the tire sidewall pressures whichever is higher.

Just got in a few minutes ago off a long trip across I70 Temps were high quite a bit of the trip, over 100 degrees F so the roadway was hot.

We saw at least 50 if not more gators along the roadway (1000 miles) and some with pretty small pieces when the tire exploded and shredded, or it was run flat longer.

Hot tires mean very hot sidewalls and that is the common failure point.

Also along the way were several passenger cars changing tires or waiting for roadside service. Hot temps find the weak points in everything.

I run 110-115 on the steer axle as I don't like hot tires, especially on the front. The rears run cool, and you can lay your hand on them even when they are in the full sun traveling.

So, bottom line weigh, consult the tire charts, adjust the psig accordingly

How did you determine you needed less air in the front than the rear.? I personally never heard of doing that. Lower psi causes more sidewall flex ( which produces heat) and more standing wave action with pavement contact (creating flex and heat). Underinflation also causes cornering understeer which again, causes more heat. I would:

1) weigh both coach axles with your normal load
2) Go to the tire manufacturers website and find their psi to weight chart. Adjust accordingly.
3) Drive it to check before doing anything else.

My bet is you’re under inflated.

I have the same coach and you have an issue some where. Maybe a dragging brake/ bad wheel bearing who knows. The only time I have seen temps of 130… was on my rear near the exhaust. Keep I mind that was. 110 degree day and I left the coach running while I was at the rest stop. I run my fronts at 75psi and they never get over 100 unless it’s that hot already outside.

Have you checked your air pressure gauge against either a calibrated or known quality one? Be worth checking if not to be sure where your at.

I am happy when my tires are at 135deg. all the way around. Air temp 100-110 and asphalt probably at 120+ the 135 doesn't seem bad.
Our tires are 75# front and 80# rear.
