Kia Rio Bolt Pattern, Wheel & Tire Sizes
TL;DR
Kia Rio hatchbacks (UB and YB generations) use a 4x100 mm, 4-lug bolt pattern with a 54.1 mm centre bore and M12x1.5 wheel studs, though you should always confirm against your own vehicle before buying wheels.
Kia Rio bolt pattern and wheel specs
The Kia Rio hatchback has gone through several generations, and while several independent wheel-fitment databases (including wheel-size.com) agree on the same bolt pattern for the third-generation UB (2011-2017, including the facelift) and fourth-generation YB (2017-2024, including the facelift), it is always worth double-checking your exact build before ordering wheels or lug nuts.
What is confirmed
- Bolt pattern: 4x100 mm (4 studs on a 100 mm circle) for UB and YB generation hatchbacks.
- Centre bore: 54.1 mm, reported consistently across the sources checked for these generations.
- Stud thread: M12 x 1.5.
Wheel and tire sizes by generation
| Generation / years | Bolt pattern | Centre bore | Stud thread | Stock wheel sizes | Common tire sizes |
|---|---|---|---|---|---|
| Rio III (UB), 2011-2017 (incl. facelift) | 4x100 | 54.1 mm | M12x1.5 | 6Jx15 ET48/ET52, 6Jx16 ET52, 6.5Jx17 ET49 | 185/65R15, 195/60R15, 185/60R16, 195/55R16, 205/45R17 |
| Rio IV (YB), 2017-2024 (incl. facelift) | 4x100 | 54.1 mm | M12x1.5 | 5.5Jx15 ET46, 6Jx15 ET46/ET48, 6Jx16 ET49, 6.5Jx17 ET49 | 185/65R15, 195/60R15, 195/55R16, 205/45R17 |
Earlier Rio generations (DC, 2000-2005; JB, 2005-2011) are widely reported at the same 4x100 / 54.1 mm / M12x1.5 spec by aggregator sites, but this page does not carry a dedicated row for them because we could not independently cross-check wheel and tire sizes generation by generation with the same confidence as the UB and YB cars.
Lug nut torque
We could not find a torque figure specific to the Kia Rio that was corroborated across multiple credible sources, so none is given here. Use the value printed in your owner's manual or ask your tire shop to torque to Kia's specification for your exact model year.
Always verify on your own vehicle
Bolt pattern and centre bore can vary by market and trim even within one generation. Before buying wheels, confirm the figures for your exact car using one or more of these sources: the driver's door jamb placard, the oil filler cap area, your owner's manual, the markings stamped into your current wheels and tires, or a dealer parts department.
Summary

Frequently asked questions
What is the bolt pattern on a Kia Rio hatchback?
For the UB (2011-2017) and YB (2017-2024) generations, independent wheel-fitment databases agree on 4x100 mm (4 lugs on a 100 mm circle). Always confirm on your own car before buying wheels, since regional trims can differ.
What is the centre bore of a Kia Rio?
Sources checked for the UB and YB generations consistently list 54.1 mm. Aftermarket wheels with a larger bore usually need a hub-centric ring to fit properly.
Can I use wheels from a different Kia Rio generation?
If the bolt pattern (4x100), centre bore (54.1 mm), and offset are all compatible, wheels can often be swapped between UB and YB generation Rios, but tire size, fender clearance, and brake caliper clearance should still be checked before buying.
Where can I find the exact wheel torque spec for my Rio?
We did not find a lug torque figure for the Kia Rio corroborated across multiple sources, so check your owner's manual or ask a Kia dealer or tire shop, since torque specs can vary by wheel material (steel vs alloy) and model year.
