Mazda Mazda3 Bolt Pattern, Wheel & Tire Sizes
TL;DR
5x114.3 (5x4.5 in) bolt pattern and 67.1 mm centre bore apply across all four Mazda3 sedan generations, but wheel diameter and tire size vary by trim - base trims typically run 16-inch wheels and sportier trims 17 or 18-inch.
Bolt pattern and centre bore across generations
Wheel-fitment databases (wheel-size.com and others) show the Mazda3 sedan has kept the same 5x114.3 mm (5x4.5 in) bolt pattern and 67.1 mm centre bore from the first generation (BK) through the current BP generation. Lug studs are M12 x 1.5 on all generations. This is confirmed generation by generation below, not assumed.
Wheel and tire sizes by trim and generation
Wheel diameter and tire size were never uniform within a generation - they depend on trim level. Base trims generally shipped on smaller wheels for ride comfort, while Sport/GT/Turbo trims used larger wheels for grip and styling. Always cross-check against the sticker on your own car since running changes and regional variants exist.
| Generation / years | Bolt pattern | Centre bore | Stud thread | Stock wheel sizes | Common tire sizes |
|---|---|---|---|---|---|
| BK (2004-2009) | 5x114.3 | 67.1 mm | M12 x 1.5 | 16 in (6.5J), 17 in optional on some trims | 195/65R15, 205/55R16, 205/50R17 (trim-dependent) |
| BL (2009-2013) | 5x114.3 | 67.1 mm | M12 x 1.5 | 16x6.5 (base/iSV/iTouring), 17x7 (S/Sport/GT) | 205/55R16, 205/50R17 |
| BM / BN (2013-2018) | 5x114.3 | 67.1 mm | M12 x 1.5 | 16 in (i trims), 18 in (s/Grand Touring) | 205/60R16, 215/45R18 |
| BP (2019-2025) | 5x114.3 | 67.1 mm | M12 x 1.5 | 16 in (base FWD), 18 in (Carbon Edition/AWD/Turbo/higher trims) | 205/60R16, 215/45R18 |
Lug nut torque
We could not verify a single official Mazda torque figure that applies across all these generations and markets from independent sources for this rewrite, so no number is stated here. Use the torque value printed in your own owner's manual or ask your dealer/tire shop - it is generation and market specific.
Always confirm on your own vehicle
Bolt patterns and bore sizes are consistent for the Mazda3 sedan family, but trims, model years and regional builds can still differ in wheel width, offset and tire size. Before buying wheels or tires, verify against:
- The driver's door jamb placard (also lists factory tire size and pressures)
- Your owner's manual
- The markings stamped on your current wheels and tire sidewalls
- A dealer parts department using your VIN

Frequently asked questions
Is the Mazda3 bolt pattern the same on every generation?
Yes - independent wheel-fitment databases confirm 5x114.3 mm with a 67.1 mm centre bore across the BK (2004-2009), BL (2009-2013), BM/BN (2013-2018) and BP (2019-2025) sedan generations. This has been verified generation by generation rather than assumed.
What stud thread size does the Mazda3 use?
M12 x 1.5 wheel studs are used across all four Mazda3 sedan generations, consistent with the 5x114.3 bolt pattern.
Can I fit 18-inch wheels from a sportier Mazda3 trim onto my base model?
Since the bolt pattern (5x114.3) and centre bore (67.1 mm) are shared across trims and generations, an 18-inch wheel from a higher trim will physically bolt on, but confirm offset, wheel width and tire clearance for your specific trim before buying, and check that your suspension and fender clearance were designed for that size.
What is the correct lug nut torque for a Mazda3?
We did not find a single torque figure confirmed to apply across all Mazda3 generations and markets, so we are not stating a number here. Check your owner's manual or the torque sticker in the trunk/door jamb, or ask your dealer - the correct torque can vary by generation and wheel type (steel vs alloy).
