How can you measure rim size?

Accurate rim measurements are necessary to replace the rims or tires. Measuring tape and a bit of labor is all that's required to measure your existing rim in a few minutes.

1. Remove the tire from the rim

   To get an accurate measurement, you must remove the tire from the rim.

2. Measure the rim width

   Measure from the bead seat on one side to the bead seat on the other side. The bead seat area is where the edge of the tire sits on the rim, and it is typically located slightly inside the edges of the rim.

3. Measure the rim's diameter

   Measure across the exposed side of the rim from bead seat to bead seat.
