The Kenda Trailer Tire and Wheel, # AM3H310, has a 18.3 inches diameter and a 8.9 inches overall width on the 8 inch tire. That is the same measurement you have on your tire. So that will be the right tire for your trailer.

The tire is also listed on the tire as being a 215/60-8, which is the new metric sizing for that tire size.

Our part number also lists the wheel bolt pattern, which is 5 on 4-1/2 inches. Most trailer tires that are smaller than 15 inches and have 5 bolts, have a 5 on 4-1/2 inch bolt pattern.

If you want to measure your bolt pattern, you will measure the distance between the center of one bolt hole on the wheel to the center of the bolt hole right next to it. That measurement should be 2-5/8 inches for a 5 on 4-1/2 inch bolt pattern.

I am sending a link of a picture of measuring the bolt pattern on a wheel.
