These are vehicle-year records whose recorded OEM ranges overlap this 2018 Ford Mustang. Overlap is not a guarantee that a specific wheel will install. Selected-wheel comparison is in the calculator below.
Evaluated 40 donor years. Listed 24 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 -1.67 mm, inner change -4.68 mm. This uses aggregated width/offset ranges, not a specific wheel.

Recorded vehicle-side thread for the 2018 Ford Mustang is M14x1.5. This donor year is recorded as 1/2"-20UNF. That is the vehicle stud/nut thread, not an intrinsic thread stamped on the wheel. Hardware must match this vehicle’s studs and the selected wheel’s seat and engagement. Existing hardware may be reusable if it already matches. Seat style is not in this dataset, so products are not a verified fit.

The following specifications are the known fitment values provided for the 2018 Ford Mustang. They may not describe every trim, package, or wheel and tire combination. Confirm the specifications for your specific vehicle using the owner’s manual, the vehicle placard, Ford service information, or the original wheel markings.
| Specification | Known value |
|---|---|
| Bolt pattern | 5x114.3 |
| Center bore | 70.5 mm |
| Thread size | M14 x 1.5 |
| Rim diameter | 18 inches |
| Rim width | 8.0 inches |
| Wheel offset | ET40, or 40 mm |
| Backspacing | 5.57 inches |
| Tire section width | 235 mm |
| Tire aspect ratio | 55 percent |
| Tire rim diameter | 17 inches |
Notice that the supplied data lists an 18-inch rim diameter and a tire rim diameter of 17 inches. These values should not be treated as one confirmed wheel and tire package. A tire with an “R17” designation is designed for a 17-inch wheel, while an 18-inch wheel requires a tire with an “R18” designation. Use the calculator and verify the original tire size and wheel size on the vehicle before ordering.
Wheel fitment also depends on brake clearance, spoke design, wheel load rating, tire load and speed ratings, suspension clearance, and the vehicle’s specific trim or performance package. A matching bolt pattern alone does not prove that a wheel is safe or compatible.
Use the calculator to compare a donor wheel and tire setup with the setup installed on your 2018 Ford Mustang. Enter the donor vehicle or donor wheel measurements in “Wheels from” and enter the Mustang measurements in “Installed on.” Review changes in wheel width, offset, inner clearance, outer position, and tire dimensions.
Plus sizing changes the wheel diameter while using a lower-profile tire to target a similar overall tire diameter. It can improve steering response and change appearance, but it may also reduce sidewall protection, increase impact harshness, and increase the risk of wheel or tire damage on rough roads.
The supplied fitment information does not identify approved alternative sizes for every 2018 Ford Mustang trim. Do not assume that a tire size used on one Mustang package is suitable for another. Compare the proposed wheel and tire dimensions in the calculator, then confirm the result with Ford information, the tire manufacturer, and the wheel manufacturer.
Common upgrades include aftermarket wheels with a different width or offset, higher-performance tires, and hub-centric rings where appropriate. These upgrades require separate checks for brake clearance, load rating, fender clearance, tire sidewall clearance, and lug-hardware compatibility. Never use spacers or adapters unless they are specifically designed and rated for the application and installed according to their manufacturer’s instructions.
Use equipment rated for the vehicle and follow safe lifting practices. A jack alone is not a suitable support while working under a vehicle.
What is the bolt pattern for the 2018 Ford Mustang?
The known bolt pattern provided for this page is 5x114.3. Confirm the pattern and wheel application before purchase because bolt pattern alone does not confirm complete fitment.
What is the center bore?
The known center bore is 70.5 mm. A wheel with a larger center bore may need correctly sized hub-centric rings. A wheel with a smaller center bore generally cannot fit over the hub without proper machining by a qualified specialist.
What lug thread size is listed?
The provided thread size is M14 x 1.5. You must still verify the lug-nut seat type, seating depth, exposed thread engagement, and torque specification for the selected wheel.
Can I install an 18-inch wheel with the listed 235/55R17 tire?
No. A tire marked R17 is designed for a 17-inch wheel, not an 18-inch wheel. The supplied data contains both an 18-inch rim diameter and a 17-inch tire rim diameter, so confirm which configuration applies before ordering a tire or wheel.
Does a 5x114.3 wheel automatically fit?
No. You must also check center bore, offset, backspacing, brake clearance, wheel width, load rating, lug hardware, and tire clearance. Use the on-page calculator for dimensional comparisons and confirm the result with OEM and manufacturer sources.
What wheel offset and backspacing are listed?
The known values are ET40, or 40 mm, and 5.57 inches of backspacing. Actual clearance can still vary with wheel width, spoke shape, brake components, suspension parts, and tire size.
How do I choose a different tire size?
Enter the proposed section width, aspect ratio, and rim diameter in the calculator. Compare overall tire diameter and clearance, then verify the tire’s approved rim-width range, load index, speed rating, and vehicle requirements with the tire manufacturer and Ford documentation.
Should I use wheel spacers to correct fitment?
Do not use spacers as a default solution. They change effective offset and can affect hub engagement, stud or thread engagement, bearing loads, and clearance. Use only products specifically rated for the application and installed according to the manufacturer’s instructions.
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.
