The Kenda # AM3H200, like the majority of trailer tires is rated for a maximum speed of 65 mph.

The 165/65-8 tire size is 16.5 inches in diameter and 6.6 inches wide, while your original 4.80/4.00-8 tires are close in diameter at 16.1 inches but are a good deal narrower at 4.7 inches wide. Since the 165/65-8 tires would extend 1 inch closer toward the trailer frame on the inside, they'll work if you have enough clearance to the inside of the tire.

The # AM3H200 165/65-8 tire would also have a higher weight capacity than your existing tires at 800 lbs apiece. This won't necessarily increase the capacity of your trailer, you'll still be limited by the trailer component with the lowest weight capacity, be it the axle, suspension, hubs or spindles.
