The thrailer had all new axles from 2018, Alcoa forged whels and new 14 ply semis truck tires.. I thught I`d be good for along time .

5 minutes into our 7 hr drive home from LOTO.. BOOM! tire blows.
Completely worn out on the inside, the middle tire also had the metald cords sticking out .. I always check the bearings but didn`t pay attention to the tires, didn`t expect issues for a long time.
Spare is a 235, all the rest of the tires are 215 ..okay
Now I have no more spares and expect the middle tire to blow at any moment.
Of course noone had these tires in stock (17.5 ") so 50 miles later I find a place. $1000 later back on the road .
....back on the road but the tires are wearing out fast.. wasn`t sure we would make it home.

Turns out the axles are bent .

$1500 later new axles installed today.

They were definitely bent compared to the new axles.

The semi truck tires and wheels weight a ton.. is that an issue with all that weight?
I`m going to replace the springs and all other hardware soon also .

So...how do you align the axles to make sure you're going down the road straight? As in left/right alignment along the long axis of the trailer?

Make sure your spring equalizer’s are all in the same position after you get it all back on the ground as sometimes one can get flipped and stuck in that position.

Each year i do a rotation
first i switch them from side to side
then i move the rear wheels in the middle
the middle up front
and the front in the rear
when i see a little wear starting on inside
i take them off the wheels and mount them in a way the inside of tires become the outside
they still use but i know what they are up to !

I took 2 pieces of angle iron and bolted to each hub. Made sure they were the same distance apart and square to trailer.

The axles locate on the spring so I don`t see much adjustment being possible.

that sucks man. I have mine in the shop right now getting 14ply all around the Cobalt trailer. I never had any issues w Ciggy After I did those. I better keep a good eye on tread, I guess.

Usually when you blow a tire on a 10ply it falls apart and takes out the fenders .
The 14 ply just blew but never came apart . There was no shoulder and I wasn`t about to change a tire halfway in a lane so I was able to go about 100 yard to an exit with the blown tire never damaging the rim.
Maybe it was just this situation or it`a another advantage to a 14 ply.. I don`t feel the trailer drag when turning like I used to with regular tires.. not having much tread is definitely a nice feature .
