My travel trailer tire rims get really hot after driving about 40mi. Is that normal?

    Make sure all the brake disk or drum pivot points are free of rust and lubricated with *synthetic brake grease. Re-pack the trailer wheel bearings and carefully adjust the castle nut.

    There is too much water in gas station air. There is no water in nitrogen and the molecules are larger than the 21% oxygen it replaces.

    Really hot is bad. 

    Something is wrong. 

    Wheels radiate heat from brake usage, and also radiate heat from bearings. 

    BEARINGS: 

    Some axles don't have brakes.  If those are hot, you need to investigate your bearing condition right away.  They need proper lubrication too.  And something that many untrained DIYers do with the axle spindle nuts is overtighten them.  There are a few ways to adjust those spindle nuts, but in no case should they ever be snugged or tightened and left that way.  A cold bearing should be slightly loose, because as it heats up from use it expands.  It needs some clearance for expansion.  With no running clearance, heat will be produced.  It's also not good for the bearing.

    BRAKES: 

    Sometimes brakes don't relax after application, and return to their non-gripping position.  They hang up and make partial contact and cause drag.  This would produce heat.  Maybe the hydraulic wheel cylinder is rusty or maybe return springs are broken?  Electric brakes have springs. 

    TIRES: 

    You also need proper air pressure in the tires.  Most trailers require more air pressure in the tires than car tires.  Many require 45 or 60 psi.  An underinflated tire will overheat. 

    You surely could lift the ends of each axle one at a time with a floor jack and when the tire is off the ground, spin it by hand.  Does it turn easily and freely?  It should!  It also should not make any grinding noises.  And you should not feel any vibrations through the tire.

    Too hot to touch is not normal. As others have said, check tire pressure, wheel bearings for proper lubrication and end play, and brakes.

    Why in hell would you even question if it's normal? You win today's stupid question prize.

    No it's not normal. Check the wheel bearings. If the trailer has brakes they are hanging up.

    Air up the tires.

    If it has trailer brakes, they could be dragging. The bearings may need repacking with grease or the tire pressures are low.

    No the bearings are shot or bone dry feeder if possible then replace

    Define normal. All wheels get hot
