Busted trailer wheels.
Oh yeah....split wheel bead seats/cracked valleys from over load and over pressure certainly not rare especially on high mileage load carrying wheels. I've had a few wheel split bead seats when I was hauling.
At one time 15" steel wheels carried a 50/65/80 psi max rating identifications depending on rim and wheel center material thicknesses. Those 50 psi 15" trailer wheels were very lite in weight compared to the 80 psi rated wheels.
Now it seems many 15" X 5 lug and most 6 lug 15" trailer wheels carry a 2830 lb load = 80 psi.
I've bought most of my truck and service trailer wheels from southwestwheel
southwest.
Give them a 1-800 for their input on their 2600 lb rated 15" X 6 lug 2600 lb load wheels and 80 psi tires. I see their adds with load E tires mounted on their 2600 lb rated steel trailer wheels.
