PCD from a measurement
Compute bolt circle diameter from lug count and stud spacing for 5, 6, and 8 lug hubs.
Bolt pattern
Enter lug count and a measured stud spacing to find the bolt circle diameter and confirm wheel compatibility for your Tacoma or other midsize truck.
Summary: This calculator works out a bolt pattern from lug count and a measured stud spacing, and checks it against the 6-lug Tacoma pattern and hub bore, for a Tacoma or any midsize pickup.
Updated
Every 6-lug Toyota Tacoma uses a 6x139.7 (6x5.5) bolt pattern, but the hub changed for the 4th gen (2024-2026): a 95.1 mm hub bore and M14x1.5 studs, versus 106.1 mm and M12x1.5 on earlier trucks. The table below comes from the same Tacoma hub data as the calculator, so it lists the pattern, bore, stud thread, and approximate lug torque for each generation.
| Generation | Years | Bolt pattern (mm / in) | Hub bore | Stud thread | Lug nut torque |
|---|---|---|---|---|---|
| 1st / 2nd gen | 1995-2015 | 6x139.7 / 6x5.5 (4WD & PreRunner); 5x114.3 / 5x4.5 on 2WD non-PreRunner | 106.1 mm | M12x1.5 | ~83 ft-lb (~113 N·m) |
| 3rd gen | 2016-2023 | 6x139.7 / 6x5.5 | 106.1 mm | M12x1.5 | ~83 ft-lb (~113 N·m) |
| 4th gen | 2024-2026 | 6x139.7 / 6x5.5 | 95.1 mm | M14x1.5 | ~97 ft-lb (~132 N·m) |
The bolt pattern matches across generations, so the hub bore and studs decide the swap. Older wheels are bored for a larger hub than the 4th gen has and drilled for smaller studs, so they need a hub-centric ring and M14x1.5 lug nuts. 4th gen wheels go the other way: their 95.1 mm bore is smaller than an older hub and will not seat on it.
| Factory wheel swap | Bolt pattern | Hub bore | Lug nuts | Result |
|---|---|---|---|---|
| 1st / 2nd gen wheels on a 3rd gen | Same (6x139.7) | Same (106.1 mm) | Same (M12x1.5) | Bolts up; check offset and backspacing |
| 1st / 2nd gen wheels on a 4th gen | Same (6x139.7) | Wheel 106.1 mm on a 95.1 mm hub: needs a 106.1→95.1 mm hub-centric ring | M14x1.5 studs through holes drilled for M12: narrow-shank M14x1.5 lug nuts | Fits with the ring and lug nuts; confirm your wheel's lug seat and hole size |
| 3rd gen wheels on a 1st / 2nd gen | Same (6x139.7) | Same (106.1 mm) | Same (M12x1.5) | Bolts up; check offset and backspacing |
| 3rd gen wheels on a 4th gen | Same (6x139.7) | Wheel 106.1 mm on a 95.1 mm hub: needs a 106.1→95.1 mm hub-centric ring | M14x1.5 studs through holes drilled for M12: narrow-shank M14x1.5 lug nuts | Fits with the ring and lug nuts; confirm your wheel's lug seat and hole size |
| 4th gen wheels on a 1st / 2nd gen | Same (6x139.7) | Wheel 95.1 mm on a 106.1 mm hub: bore too small, will not seat | n/a (the bore blocks the swap) | Will not fit |
| 4th gen wheels on a 3rd gen | Same (6x139.7) | Wheel 95.1 mm on a 106.1 mm hub: bore too small, will not seat | n/a (the bore blocks the swap) | Will not fit |
Other common truck bolt patterns the calculator matches: 5x114.3 (5x4.5), 5x127 (5x5), 5x150 (5x5.9), 6x114.3 (6x4.5), 6x135 (6x5.31), 8x165.1 (8x6.5).

What it does
Compute bolt circle diameter from lug count and stud spacing for 5, 6, and 8 lug hubs.
Matches the measured value to a known pattern within tolerance and names it.
Bolt pattern, hub bore, and stud thread by generation, plus interchangeable Toyota and Lexus wheels.
Bolt circle diameter is computed from lug count and your measured stud spacing with standard circle geometry. The Tacoma hub bore and stud figures are our own fitment data, not from the Toyota page linked here, which documents wheel sizes and lug nut torque.
Every 6-lug Toyota Tacoma is 6x139.7, also written 6x5.5. Only early 2WD non-PreRunner models used 5x114.3.
Yes on 1st to 3rd gen, which share 6x139.7 and a 106.1 mm hub bore with the 4Runner, FJ, GX, and 1st-gen Tundra. On a 4th gen you also need a 106.1 to 95.1 mm hub ring and M14 lug nuts.
Measure from the center of one stud to the outer edge of the stud two positions away. That distance is very close to the bolt circle diameter for a 5-lug wheel.
Only if the bolt pattern, hub bore, and stud thread all match, so measure or check the spec rather than assuming. A Tacoma needs 6x139.7 with a 106.1 mm bore on 1st to 3rd gen or 95.1 mm on 4th gen, then an offset that suits the truck.
