Since your tires are 7.00X15LT, the "15" in that tire size means that they are on 15 inch rims. If you need it I have articles attached that explain how to measure a trailer tire and wheel.
When you measure make sure you're measuring inside to inside at the tire bead seat. The same with the width, inside to inside because what you're measuring on the dimensions is where the tire is seated. I also have videos attached that show(s) how to measure a tire and wheel.
