How much wheel heat is acceptable?

    I was told many years ago that the wheel barring temp should never reach 140F if it does than you need to replace it.

    I just ordered a digital thermometer from Amazon... (They have so many uses.) I'm going to test the heat build up again on Sat. to see if it's really a legitimate concern.

    If it's too hot there is a part of me that thinks it could be my brakes. I guess if I jacked up the wheel off the ground with the trailer brake controller connected and it had too much resistance to turning it would tell me if the brakes might be an issue?

    I aways figure about 30 degrees warmer than the outside temp or about the same asphalt pavement, which ever is warmer. They should be a little warmer than your TV tires.

    So my digital thermometer arrived. Thanks for suggesting that. I went for another shakeout cruise . I measured temps on my tires that were about 10 degrees different. One was about 125 the other about 135. I'm asking myself if this could be due to tire inflation.I have been using the air compressors at the local gas station. Their compressor won't inflate my tires above 54lbs and the tires will take up to 65lbs. How much of a factor do you think the 54lbs of pressure is in my tire temperature ?

    Did you measure the temp of your TV tires?

    Yes I did and it was lower, but I can't remember how much.

    I also jacked up my trailer last night to see how freely the wheels spin. The wheel/tire that is heating up more doesn't spin quite as freely as the wheel that has the cooler temps. I will monitor the heat on our trip to see if it stays consistent. We are leaving this afternoon for our trip to Gatlinburg Tn. I have my digital thermometer in my driver door pocket. I will monitor it every time I stop.

    If you go with the 140 I was taught That 135 axle needs help. If you dont have any wiggle in the wheel I would say it is a good time to repack them.

    Running 10 lbs. low will make a difference. What was the hub temps?

    What type of grease did you use, and how much preload on the bearings? These little buggers we pull around are notorious for blowouts and seized bearings if not maintained, so take zero chances with any of these items, get the best possible grease, bearings, tires, and inflate them to the max recommended cold pressure.
    My little 1100lb, 8ft Starcraft was 'overkilled' right after purchase- Load range D radials, synthetic hi-temp disc brake wheel bearing grease, and new Timken brand bearings. The synthetic should offer a little more temp buffer before breakdown, and 'disc brake/hi temp' is a must. When adjusting bearings, be sure to first tighten down good (50-60ft/lb) while rotating hub, then back off til its loose and take them to finger tight, plus a hair more- especially if you replaced the bearings, so they are seated correctly. Believe it or not, a hair snug is better than a hair loose. If those rollers arent preloaded a bit and start sliding instead of rolling, youre in trouble.
    Keep those tires at max, always!
