Upon getting the rim measurement, you should utilize a tape measure to measure the diameter of the rim. To do that, place the tip of the tape measure on the fringe of the rim and prolong it to the alternative edge. The measurement must be taken from the within fringe of the rim to the surface edge. The diameter of the rim must be the identical because the rim measurement that you simply discovered on the tire measurement code.
Finding the Tire Measurement Data
The tire measurement info could be discovered on the sidewall of the tire. It’s sometimes a collection of numbers and letters that point out the tire’s width, facet ratio, rim diameter, and cargo index and velocity score. For instance, a tire with a measurement of 225/60R16 91H has a width of 225 millimeters, a side ratio of 60%, a rim diameter of 16 inches, a load index of 91, and a velocity score of H.
Discovering the Rim Diameter
The rim diameter is the diameter of the steel rim that the tire is mounted on. It’s sometimes measured in inches. To seek out the rim diameter, find the quantity that follows the “R” within the tire measurement info. For instance, within the tire measurement 225/60R16 91H, the rim diameter is 16 inches.
| Tire Measurement | Rim Diameter (inches) |
|---|---|
| 225/60R16 91H | 16 |
| 235/45ZR17 | 17 |
| 245/40R18 97Y | 18 |
Measuring Rim Width with a Caliper
To measure the rim width utilizing a caliper, observe these steps:
1. **Select the proper caliper:** Use a vernier caliper or digital caliper with adequate vary to measure the rim width.
2. **Clear the rim:** Take away any dust or particles from the rim to make sure correct measurements.
3. **Find the bead seat:** Establish the internal and outer bead seats, that are the perimeters the place the tire beads make contact with the rim.
4. **Place the caliper:** Place the jaws of the caliper perpendicular to the bead seats, with one jaw touching the internal bead seat and the opposite jaw touching the outer bead seat.
5. **Apply even strain:** Gently tighten the caliper jaws to safe them in place with out inflicting injury to the rim.
6. **Learn the measurement:** Word the measurement displayed on the caliper’s scale. The width is the distinction between the internal and outer bead seat measurements. File this worth in millimeters or inches, relying on the caliper used.
| Measurement | Width |
|---|---|
| Inside Bead Seat | -23mm |
| Outer Bead Seat | 82mm |
| Rim Width | 82mm – 23mm = 59mm |
7. **Repeat the method:** Take a number of measurements at totally different factors alongside the rim to make sure accuracy.
Utilizing a Ruler to Measure Rim Diameter
Measure the diameter of the rim from bead to bead, which is the space throughout the within of the rim from one aspect to the opposite. Use a ruler or a measuring tape to measure the diameter precisely. Maintain the ruler straight throughout the rim and browse the measurement on the level the place the ruler intersects the bead on the alternative aspect.
Measure the Width of the Rim
Measure the width of the rim from flange to flange, which is the space between the outer edges of the rim. Place the ruler throughout the rim, perpendicular to the diameter measurement. Measure the space between the 2 flanges.
Measure the Offset of the Rim
Measure the offset of the rim, which is the space between the middle of the rim and the mounting floor. Place the ruler on the mounting floor of the rim, with one finish of the ruler aligned with the middle of the rim. Measure the space from the tip of the ruler to the sting of the rim.
Calculate the Backspacing of the Rim
Calculate the backspacing of the rim, which is the space between the mounting floor and the again of the rim. Subtract the offset measurement from the width measurement.
| Measurement | Find out how to Measure |
|---|---|
| Diameter | Measure from bead to bead throughout the within of the rim. |
| Width | Measure from flange to flange throughout the surface of the rim. |
| Offset | Measure from the middle of the rim to the mounting floor. |
| Backspacing | Subtract the offset from the width. |
