wilson flatbed trailer...tire problem

I've got a 2005 aluminum wilson that I bought last year.
Recently my inside tire on the one side of the axle has started wearing around the edge but not evenly. More like flat spot..normal..flat spot..normal. all the way around.
I've also had issue with my ABS light coming on sometimes and then going off. Usually with a brake application...but sometimes with no brake application.
I'm not sure if the two issues are connected or not.
Tire inflation are good.
Does it sound like a bearing issue? Can I take it to a shop to get them to check and tighten it...or should a person just change it out when it's a little loose?
I was also thinking shocks as my truck was having the same issue on the back drive. Felt the front drive shocks after a couple hundred miles and they were warm. Rear drive shocks were stone cold so I changed them out.
Just thought I'd ask here. Can't afford to be throwing money at it to see if it's this or that. I'd rather know what it is for sure and fix it.

 

Thanks. I'm heading on days off pretty quick. Think I'll do the shocks because im not sure when they were done last...then test the bearing for movement at the same time. Then throw some used tires on that spot. If it starts again then get an alignment.
I just wasn't sure if a bearing can be tightened back up to specs if there is some movement...or if you just change it out? I've got no seal leak or anything
