From the research I did on your tire size of 8.55-15ST that would indicate that the modern tire size equivalent is ST225/75R15 which is a very common tire size.

The Provider trailer tire part # TTWTRTM2257515D is a great option for that size. It has a higher speed rating than most trailer tires at 81 MPH and is also priced great.

Answer 6

There's no harm in putting tires with a higher load range on your trailer when replacing them. With that being said there's no gain either. At least not from the load range. The tires technically have a higher capacity but that isn't…

I reached out to Dexter and they no longer make that axle. I can confirm based on the bearing sizes you gave that you have a 3,500 lb capacity. If you determine you just want to replace the hub, I recommend the Trailer Hub and Drum Assembly for…
