Trailer Tires, How hot is too hot?
Well I blew out another trailer tire on my annual trip to the keys this past week. The blow out occured on the front passenger side of my trailer and the tires were just over a year old. Purchased a new set for the front axel and double checked for the correct pressure (50 LBS). Being paranoid I shot all four tires and hubs with my temp gun each stop on the way home and on long runs was surprised to seem the tires hitting high 130's(136-138). This seems way too hot. Is this OK or is this what is causing my blowouts? My Pathfinder 22v is well within the weight limits of the four tires.
What gives.

All four tires on the trailer were about the same temp?
Just for ha ha's, why not find a scale (truck stop) and see what the wt of the boat/trailer is?
Overheating will cause blow outs. As said, stop by a truck stop or even the local dump and weight it. Boats get fat as you put more crap on them.

I'm thinking of going to a LT truck tire next time around. My neighbor did about 6 years ago and hasn't had a problem since.
Tires were reading about the same on my tow vehicle. I have much better luck with radial tires than bias ply.
I have been reading good things about these lately......think I will try them next time. Speed rated to 99 MPH.

I do try to stay around the 65 MPH mark, and run max PSI. Also, I balance my tires and change them out every 3 or 4 years.
Exactly!!!@# I run from Orlando to Englewood and back on I-75 & I-4. Make two stops while enroute. All tires are about 135 degrees (truck and duel axle trailer) hubs about 125 degrees.
Here's the deal. I've had one flat tire on my boat trailer in 12 years. That's running between Orlando and Englewood at 65 mph. However, when we use to make our annual trip to the Keys, I guarantee you, we would have one flat on the trailer either coming or going. I don't understand it. If I can pull at trailer 150 miles for years without a flat, then why can't I pull a trailer 350 miles without a flat??????
I am crossing my fingers for a rating of E . Did not really know of the letter designation only the load weight and rebber density.
"Most experts consider 195 degrees Fahrenheit as the “line in the sand” when it comes to tire temperature: Beyond that point, the temperature will start impacting tire life. At 250 degrees, a tire will start to lose structural strength, could begin experiencing tread reversion and the tire will begin to lose strength."
If they get dangerously hot, check all tire pressures, park and let the tires cool, and redistribute load.
Have a safe trip.
What I suggest is to take the truck and trailer and park it on level ground. Then take a level and place it oh the I-beam near the hitch. Is it level? if it is then both axles are carrying the same load. If not the you need to raise or lower the hitch until it is level.
It is very important on tandem and triple axle trailers that all axles are carrying the same load. Otherwise, the front or rear tires are carrying the majority of the weight as are those hub bearings. You should also check what the "Load Range" is on those tires.
I just towed my Pathfinder 15T 1,500 miles last week with out issue.
I have a Shorelander trailer with 4.80 x 12 tires/rims.
I was very concerned about blowing out a tire on such a long trip with such small tires.
I bought 2 new tires and a spare from eTrailer mounted on galvanized rims that are Bias Ply Load range C and Speed Rated at 81 mph (this is stamped on the side of the tire). They were inflated to max pressure of 90psi.
I replaced the hubs and bearings as well.
My boat is pretty light- the whole rig with boat/motor/trailer/batteries/gear etc is about 1,300 lbs.
I towed at 73MPH and my tires never got more than warm to the touch.
Luckily- I made the trip without issue.
If the its squatting towards the front, then you can adjust the hitch so that its higher. I helped a buddy out with this before.. He was going to add extra springs to his vehicle, and instead I had him buy a different hitch receiver which made the ball sit higher.. Once the trailer was hooked up, the truck squatted the same, but the trailer was level and the weight was distributed to both axles evenly.
Get LT tires or tires rated higher. Tire Kingdom makes some rated for 75 and some other brands are up to 80. I would go light truck tires. Be hard to blow those in any conditions
Carlisle, Goodyear Marathons, Kuhmo's, all make quality trailer tires.
