To upgrade the axle and hubs on your Northern Hardware Trailer, I recommend looking at an Axle-Less System like the Timbren # A20RS545. This suspension system will provide you with a smooth, quiet, and safe ride and can completely eliminate the need for an axle. It is designed to fit any frame width and features straight, EZ Lube spindles for easy bearing lubrication.

This particular system is rated for 2,000 pounds and includes idler hubs with a 5 on 4-1/2 inch bolt pattern. They will be compatible with any wheel that matches this bolt pattern, including 15 inch units like the impressive Hi-Spec Series S5 # AM22323HWTB.

I have attached a short video demonstration on this product that you can check out. I have also attached a link that will take you to our available selection of 15 inch wheel and tire combos with a 5 on 4-1/2 inch bolt pattern for you to look through. You can filter through the different tire sizes by using the facets on the left side of the page.

will tires 215/60-8 18.5x8.5-8 Load Range C fit my northern tool trailer #37561?

From what I could find it looks like your Northern Tool Trailer originally came equipped with 12" tires (4.80-12), so going to a 215/60-8 like # AM3H290 might be possible but it'll be a pretty big change. You're looking at a smaller overall height/diameter by a couple inches and a larger width by about 4". The main thing you'll need to look at is your existing clearance between the tire's side wall and frame, making sure you have enough room for this extra width. I don't have these dimensions at my disposal so you will have to measure.
