Typical Axle Ratings Based on Axle Diameter
Question:
What do you think the weight rating for a trailer with 1 7/8 hitch ball would be for a round axle 1 1/4 inch diameter, 38 inches long center to center on springs. Has 2 leaf springs 1 3/4 inches wide at each hub with 4.80-8 tires with 4 hole rims. We are going to use this trailer to transport a motorcycle that weighs 900 pounds from Florida to Maine this summer.

Expert Reply:
Typically 1-1/2 to 1-3/4 inch diameter axles have 1,000-1,200 lb capacities. Since your axles are smaller than that I can only assume slightly less than 1,000 lbs. On some trailers there will be a plate or sticker that will list the trailer capacities.
Since your motorcycle is right at 900 lbs I would be hesitant to put it on that trailer.
Here's a breakdown on typical axle weight ratings based on axle diameter:
1,000-lb - 2,000-lb Axles: 1-1/2" - 1-3/4" diameter
3,500-lb Axles: 2-3/8" diameter (Can have a 3-1/2" diameter, but rarely)
6,000-lb - 7,200-lb Axles: 3" diameter
8,000-lb Axles: 3-1/2" diameter
9,000 lb Axles: 4" diameter
10,000-lb Or more axles: 5" diameter
