Kia Forte Bolt Pattern, Wheel & Tire Sizes
TL;DR
The bolt pattern has stayed 5x114.3 across all Forte generations, but wheel size ranges from 15 to 18 inches depending on trim (base models vs GT/GT-Line), so check your door placard or tire sidewall before buying wheels.
Kia Forte bolt pattern and center bore
Across the three main Forte generations tracked by wheel-fitment databases (TD 2008-2013, YD 2014-2018, and BD/BD facelift 2019-2025), the bolt pattern is consistently listed as 5x114.3 mm (also written 5x4.5 in). Independent wheel-fitment sites also list a 67.1 mm center bore and M12x1.5 wheel studs for these years, though this bore figure comes from aftermarket-wheel databases rather than a Kia factory document, so treat it as a strong starting point rather than a guarantee for your exact car.
Stock wheel and tire sizes by generation
Wheel and tire sizes vary mainly by trim level and engine, not by generation. Base and mid trims (1.8/2.0 MPi, 2.0 GDi) typically ride on 15 or 16-inch wheels, while GT and GT-Line trims with the 1.6 turbo engine step up to 17 or 18-inch wheels with lower-profile tires.
Data table
| Generation / years | Bolt pattern | Centre bore | Stud thread | Stock wheel sizes | Common tire sizes |
|---|---|---|---|---|---|
| Forte I (TD), 2008-2013 | 5x114.3 | ~67.1 mm (verify on car) | M12x1.5 | 15-17 in (5.5J-7J) | 195/65R15, 205/55R16, 215/45R17 (SX/Koup trims) |
| Forte II (YD/YD facelift), 2014-2018 | 5x114.3 | ~67.1 mm (verify on car) | M12x1.5 | 15-17 in (6J-7J) | 195/65R15, 205/55R16, 215/45R17 |
| Forte III (BD/BD facelift), 2019-2025 | 5x114.3 | ~67.1 mm (verify on car) | M12x1.5 | 15-18 in (6J-7.5J) | 195/65R15, 205/55R16, 225/45R17 (2.0L trims); 205/50R17, 225/40R18 (1.6 T-GDi GT trims) |
Lug nut torque
Aftermarket references commonly cite a lug torque range of roughly 79-94 lb-ft (108-127 Nm) for the Forte, but this figure is not confirmed against a Kia factory manual for every model year, so verify the exact torque spec in your own owner's manual before tightening wheels.
Where to confirm your exact specs
- The driver's door jamb placard lists the factory tire size and recommended pressure for your specific car.
- Your owner's manual lists the correct lug torque and any towing-related wheel notes.
- The tire sidewall itself shows the exact size currently mounted.
- A wheel shop can measure your bolt pattern and center bore directly with a gauge if you plan to fit aftermarket wheels.

Frequently asked questions
Does the Kia Forte bolt pattern change between generations?
No - the 5x114.3 mm (5x4.5 in) bolt pattern is consistently reported across the TD (2008-2013), YD (2014-2018), and BD (2019-2025) generations by wheel-fitment databases, so wheels sized for one generation will physically bolt to another, though offset and center bore should still be checked.
What center bore does the Kia Forte use?
Wheel-fitment sites commonly list 67.1 mm for the Forte's center bore, but this is not confirmed in a Kia factory document for every trim, so if you are fitting aftermarket wheels with a different bore, use hub-centric rings and double check the fitment with your wheel supplier.
Can I put 18-inch wheels on a base Forte that came with 15s?
Yes, in most cases, since the bolt pattern (5x114.3) is shared across trims - but you need to match offset and tire diameter carefully to avoid rubbing, and a base Forte's suspension and brakes were tuned around smaller stock wheels, so consult a wheel shop for the correct offset range.
What size are the lug nuts on a Kia Forte?
Aftermarket references list M12x1.5 as the stud/lug nut thread size across Forte generations, and a torque of roughly 79-94 lb-ft (108-127 Nm) is commonly cited, but confirm the exact torque value in your own owner's manual since it can vary by wheel type (steel vs alloy).
