    I took my camper out for a shakeout cruise last Saturday here in Fl. in preparation for a trip to Tn. next week. I did a 20 mile loop which included interstate driving. I was going 65 to 70mph. The outside temps were in the 90's. I stopped once at a rest area and walked around the camper and layed my hand on the wheel. It was pretty warm but not red hot by any means (I didn't get burned). Both wheels felt about the same. I just had replaced the bearings about 1000 miles ago on the wheel the felt slightly warmer. How much heat is acceptable and should I be concerned?

    How much heat is acceptable depends on the tire rating. Most trailer tires are not made to go consistently above 65 mph. I had to pay extra for my tires that are rated up to 80 mph. But that rating does not mean I would ever pull it at that speed.

    What part of the wheel did you touch.

    I've always went by if I can keep the back of my hand on it without needing to pull it off then the temperature is fine.

    I laid my palm on the part of the wheel that is just above the rim. I did it on both wheels. I guess the wheels may have been warmer too due to braking before I stopped???

    I'm probably a little paranoid. I've only replaced 3 or 4 wheel bearings in my whole life. I always wonder if I've over tightened the installation. I also noticed that the wheel I replaced the bearings on had a few more grease marks on it than the other wheel. Maybe it was just spitting out a little bit of the extra grease. I think I'm going to clean off that wheel and do another shakeout cruise this weekend and see how it looks.

    You need a digital thermometer. I used a non-contact from Harbor Freight.

    Thank you. We have a Harbor Freight right down the street. What would be an acceptable temperature?

    I use an infra-red that I won at the pop up gathering in Hingam Mass several years ago! My hub temps are usually high 90s to low 110s range. Ambient temp seems to make a little, but not much, difference. I check them every time I stop whether it be for fuel, bathroom, whatever.

    My tires are usually 100 to 130 if I recall correctly. My hubs may be warmer because I just braked when stopping.

    Don't expect them to be exactly the same. You just want to see one way higher than the other. I have seen a 20-30 degree differnce after a tow with the sun shining on one side for many miles.

    I put it right against the tire and then hub near a wheel stud.

    Our hubs really get no warmer than any other metal part of the camper. We use the back of the hand technique as well.

    As an aside, you might want to check your towing speed. In addition to the fact that your tires might not be rated for higher speed, in certain places you are considered a "truck" while towing on the highway- and subject to their speed limits.

    Dang, you guys are tough.. I was only going 65 to 70mph. In Fl. that puts you at risk for being rear ended in the slow lane...:D

    Ah yes, I've had the honor of driving on the Florida Turnpike several times. [:D]

    Seriously though, I mentioned it because you said that you'd be driving up to TN. Different states have different rules and all...

    Here in WA, they do enforce the speed limit as well as not entering the far left lane with a trailer. So...it might behoove you to check out the rules where you're going to be travelling. It would suck to get a ticket for something completely avoidable.

    Have you packed the bearings? I'd do that before asking myself if they are too hot.

    If it's warm and you know the bearings are tight and packed and you inspected brakes, trailer on buddy! If you know nothing about the state of bearings, then the first job is to pack them. Don't fret over how hot they should or shouldn't be because now you've seen them with your own eyes.

    Drove maybe 1000 miles and I "hand" checked the tires - they were warm. Was in middle of long trip from Alabama to California.

    I guess I missed you replace the bearings - did you replace the bearing races as well or just the bearings? Improperly match races can case overheating too.

    If you set tightness correctly, used quality grease and the brakes are not dragging you are good to go!

    I don't know if you'll find an acceptable temp range on paper.
