These are vehicle-year records whose recorded OEM ranges overlap this 2014 Hyundai Genesis Coupe. Overlap is not a guarantee that a specific wheel will install. Selected-wheel comparison is in the calculator below.
Evaluated 4 donor years. Listed 4 eligible overlaps (not all evaluated years are compatible). Showing all listed.
Years grouped because recorded compatibility evidence is equivalent. Each year keeps its own page.
Approximate position vs the mid OEM package: outer change -2.18 mm, inner change -4.18 mm. This uses aggregated width/offset ranges, not a specific wheel.
Only years with evidence-based interchange relationships are listed. Adjacent years are not assumed compatible.

This guide covers the known wheel and tire specifications for the 2014 Hyundai Genesis Coupe. The supplied data may represent only part of the vehicle's fitment information, and specifications can vary by trim, package, market, or replacement wheel. Confirm the final setup with the vehicle owner’s manual, the driver-side door-jamb label, and the markings stamped or cast into the wheel.
The following specifications are the known OEM fitment values provided for this page:
| Specification | Known value |
|---|---|
| Bolt pattern | 5x114.3 |
| Center bore | 67.1 mm |
| Thread size | M12 x 1.5 |
| Rim diameter | 18 inches |
| Rim width | 7.5 inches |
| Wheel offset | ET32 |
| Backspacing | 5.01 inches |
| Tire size | 225/45R18 |
| Tire section width | 225 mm |
| Tire aspect ratio | 45 percent |
These values identify the known wheel and tire configuration, but they do not confirm every clearance requirement. Brake caliper clearance, suspension clearance, fender clearance, load rating, tire construction, and trim-specific differences must be checked before installation. Do not assume that every 5x114.3 wheel will fit.
Use the calculator to compare wheels from a donor vehicle with the wheel setup installed on your 2014 Hyundai Genesis Coupe. Enter or select the donor vehicle under “Wheels from” and the Genesis Coupe under “Installed on.” Review the bolt pattern, center bore, wheel dimensions, offset, and tire size comparison before making a purchase.
The calculator also allows you to enter a custom wheel size. Adjust rim diameter, rim width, and offset to evaluate an aftermarket wheel or a proposed plus-size setup. You can also enter a custom tire section width and aspect ratio. When you change rim diameter, the calculator updates the tire diameter in the comparison, helping you evaluate overall diameter changes rather than looking at wheel diameter alone.
Use the calculator as a screening tool, not as a substitute for a physical test fit or OEM verification. A result that appears compatible still requires confirmation of brake, suspension, body, and tire clearance.
Plus sizing changes the wheel diameter while using a lower-profile tire to keep the overall tire diameter close to the original. The goal is to preserve speedometer behavior, gearing, ground clearance, and electronic-system expectations as closely as possible. A larger wheel can also reduce tire sidewall cushioning and increase the risk of wheel or tire damage on potholes.
The known reference tire for this page is 225/45R18. The calculator can compare a custom tire section width and aspect ratio with that reference. Treat any proposed size as unconfirmed until the tire manufacturer lists it as suitable for the selected wheel width and a physical clearance check has been completed.
Wider tires may improve dry-road contact but can increase the chance of rubbing and may affect steering feel, road noise, wet-weather behavior, and fuel economy. Changing offset can move the wheel inward toward suspension components or outward toward the fender. Do not select a wheel based on bolt pattern alone.
Useful supplies for a careful wheel installation include a calibrated torque wrench, correctly sized socket, breaker bar, jack and jack stands rated for the vehicle, wheel chocks, a tire-pressure gauge, and a wire brush for cleaning the hub face. A hub-bore gauge or accurate caliper can help verify wheel center-bore measurements, while a tread-depth gauge is useful when inspecting used tires.
For compatible maintenance tools, see automotive torque wrenches on Amazon and digital tire-pressure gauges on Amazon. Always follow the tool manufacturer’s instructions and use jack stands on a stable surface. Never work under a vehicle supported only by a jack.
What is the bolt pattern for the 2014 Hyundai Genesis Coupe?
The known bolt pattern is 5x114.3. Confirm the wheel’s mounting pattern before purchase because a similar-looking pattern is not interchangeable.
What center bore does the 2014 Hyundai Genesis Coupe use?
The known center bore is 67.1 mm. A wheel with a smaller center bore will not fit over the hub. A larger bore may need correctly sized hub-centric rings, depending on the wheel and installation requirements.
What is the known factory wheel and tire size?
The supplied fitment data lists an 18x7.5 wheel with ET32 offset and a 225/45R18 tire. This information may not cover every trim or market, so verify the vehicle label and wheel markings.
Can I use any 5x114.3 wheel?
No. Bolt pattern is only one part of fitment. You must also check center bore, offset, width, backspacing, brake clearance, lug-seat design, load rating, and tire clearance.
What lug thread size is listed for this vehicle?
The known thread size is M12 x 1.5. The correct lug nut seat and required hardware can vary with the replacement wheel, so confirm both thread and seat style before installation.
How do I compare a different wheel or tire size?
Enter the donor vehicle under “Wheels from” and the 2014 Hyundai Genesis Coupe under “Installed on.” Then use the custom wheel and custom tire fields to compare diameter, width, offset, and tire dimensions. A physical clearance inspection is still required.
Will changing rim diameter change the tire comparison?
Yes. The calculator updates tire diameter when you change rim diameter. This helps show how a lower-profile tire may be needed when moving to a larger wheel, but it does not confirm that the tire is approved for the wheel or vehicle.
Where can I confirm the final specifications?
Check the driver-side door-jamb label, owner’s manual, OEM service information, and the markings on the existing wheel. For aftermarket wheels and tires, also use the manufacturer’s fitment, load-rating, and clearance information.
Wheel interchange depends on more than bolt pattern. Where data is available, this site compares recorded OEM values:
A normal wheel spacer does not change bolt pattern. Hub rings cannot enlarge a wheel bore that is smaller than the hub. Brake clearance and tire package fitment still require vehicle-specific checks when not confirmed in the dataset.
