Expert Reply:

Yes, with trailer tires you do need to always keep the tire inflated to it's max PSI rating to ensure you get the full weight capacity of it and minimize heat build up which might cause premature failure.

So to ensure you get the full weight capacity of the # AM30859 you'd need to inflate it to 105 PSI when cold.

From what I could find, the Harbor Freight trailers do say not to exceed 45 miles per hour in the owners manual. That being said, the tires they use are not rated very high and may be the limiting factor. The trailer you have looks to use a 5 on 4…
