5x135 Bolt Pattern
5x135 means 5 lugs on a 135.0 mm bolt circle, which is 5.31 inches, so the same pattern is written 5x5.31. Check a measurement against it below.

5x135 dimensions
| Measurement | mm | inches |
|---|---|---|
| Bolt circle (PCD) | 135.0 mm | 5.315 in |
| Neighboring studs, center to center | 79.4 mm | 3.124 in |
| Skipping one stud, center to center | 128.4 mm | 5.055 in |
Measure from the center of one stud to the back of the stud farthest from it.
Close patterns
Driven Products notes that a 5-lug measurement with a tape is only an estimate unless you use a bolt pattern gauge. Patterns a millimeter or two apart need a gauge or the wheel's stamped size to tell apart.
Every way to write it
| Unit | Value |
|---|---|
| Millimeters | 135.0 |
| Inches | 5.315 |
| Centimeters | 13.50 |
| Neighbor studs (mm) | 79.4 |
To convert, divide the millimeter figure by 25.4: 135.0 ÷ 25.4 = 5.315 inches. Going the other way, multiply inches by 25.4.
Measuring a 5x135 pattern with a tape
Center to center across one skipped stud reads 128.4 mm (5.05 in); multiply by 1.051 to get 135.0 mm. The center-to-far-edge method gives the skip distance plus half the stud diameter, so the reading depends on stud size:
| Stud size | Center to far edge |
|---|---|
| 12 mm stud | 134.4 mm (5.29 in) |
| 1/2 in stud | 134.7 mm (5.30 in) |
| 14 mm stud | 135.4 mm (5.33 in) |
Those readings land close to, but not exactly on, the 5.31-inch bolt circle, which is why the method is an estimate.
Other 5-lug patterns compared
| Pattern | Bolt circle | Difference | In inches |
|---|---|---|---|
| 5x100 | 100.0 mm | −35.0 mm | -1.378 in |
| 5x108 | 108.0 mm | −27.0 mm | -1.063 in |
| 5x112 | 112.0 mm | −23.0 mm | -0.906 in |
| 5x114.3 | 114.3 mm | −20.7 mm | -0.815 in |
| 5x120 | 120.0 mm | −15.0 mm | -0.591 in |
| 5x127 | 127.0 mm | −8.0 mm | -0.315 in |
| 5x139.7 | 139.7 mm | +4.7 mm | 0.185 in |
Wheels must match the bolt circle exactly; an adapter is the only way to mount a different pattern.
What your tape should read
For 4, 6 and 8 lugs the first column is center to center straight across; for 5 lugs it is center to center across one skipped stud. The second column is the distance between neighboring studs, a handy cross-check on any pattern.
| Pattern | Main reading | Neighbor studs |
|---|---|---|
| 4x100 | 100.0 mm (3.94 in) | 70.7 mm (2.78 in) |
| 4x108 | 108.0 mm (4.25 in) | 76.4 mm (3.01 in) |

| 5x112 | 106.5 mm (4.19 in) | 65.8 mm (2.59 in) |
| 5x114.3 | 108.7 mm (4.28 in) | 67.2 mm (2.65 in) |
| 5x120 | 114.1 mm (4.49 in) | 70.5 mm (2.78 in) |
| 5x127 | 120.8 mm (4.76 in) | 74.6 mm (2.94 in) |

| 6x114.3 | 114.3 mm (4.50 in) | 57.1 mm (2.25 in) |
| 6x135 | 135.0 mm (5.31 in) | 67.5 mm (2.66 in) |
| 6x139.7 | 139.7 mm (5.50 in) | 69.8 mm (2.75 in) |
| 8x165.1 | 165.1 mm (6.50 in) | 63.2 mm (2.49 in) |
| 8x170 | 170.0 mm (6.69 in) | 65.1 mm (2.56 in) |
Computed from the bolt circle: straight across = PCD; skip one (5 lug) = PCD × sin 72°; neighbors = PCD × sin(180° ÷ lugs).
Before you buy wheels
- The stud count and bolt circle must match exactly; a wheel drilled a millimeter or two off will not seat properly on every stud.
- Check the center bore and the lug nut or bolt seat type along with the pattern.
- When the wheel lists its pattern, compare it with the number stamped on your current wheel rather than a tape reading.
