Trailer Tire Wear Uneven???

[Papa Rick]

I have a 1974 Utopia Log Trailer that was completely reworked three years ago. I bought it last Sept and have had weird tire wear on them.

It has shown up on the inside portion of my tires, like it is bouncing up and down, and wearing faster than the rest of the tire. It does this on four of the eight tires.

I have had the trailer in three different shops to check alignment and all three said that it is in alignment, no adjustment needed. Any suggestions on this one???

Everyone that has looked at it tells me the trailer is out of alignment, but when checked (2 places didn't even charge me after they checked the alignment) due to not needing any adjustment.

I am buying used tires running them until they get down half way on the inside tread, usually 10,000 to 15,000 and then have them dismounted and turned around and remounted to get the most life out of them.

Any suggestions would be greatly appreciated.

Is it just on one side of your trailer duals or both?

Left Side front axle both tires, Right side front axle inside tire, right side rear axle outside tire???

on the tires that are being flipped on the rims each 10 - 15k ....... i would also switch those to the opposite side of the trailer to maintain direction of rotation

does it pull, steer the truck, or dog-track?


i would check wheel-end play, then replace all the shocks

Tires have to be matched. I've already gone through this twice. I had a tire go bad twice and put a new one on. The tire next to it wore out in 3,000 miles due to the fact it was smaller than the new one and was skimming the road. The tires need to wear together as brand new tires.

Forget to mention this is a spring ride trailer. Had all the springs, hangers, bushings, etc...., checked and nothing found. Trailer pulls straight and does not dog-leg, pull or steer the truck at all.

I have bought two tires at the same time and though it slowed down the wear, it did not stop it???????

This really has me puzzled???

what about inflation pressure? I had the same problem on my tarnscraft 48' flat bed with a spread 10 axle. And are you running new tires or retreads? Ive been told that retread will sometimes have different ride heights even if there the same brand of core.

me too-I was also going to mention that you have your axle's and leaf springs checked but you already did that so I'm kinda clueless with this

All tires should be of the same height and air pressure. The tallest tires will take the heaviest part of the load. If you have the same size tire, but are different brands, they may be different height. I like the same brand and tread design on each hub.
Are the shock in good working condition? A tire/whell combo that has a heavy side may hit the road surface harder, making the lighter side of the combo leave the road.
