2021- Ford Mustang Mach-E 18" OEM Tire Replacement Guide

The 18” wheel was the base fitment on the Mach-E Select and the standard wheel on the California Route 1. Both trims shipped with a 225/60R18 grand touring all-season tire. It is a tall, comfortable tire on a narrower wheel that is well matched to the Select’s value positioning and the Route 1’s efficiency focus. This guide covers what came from the factory, what matters when replacing it, and which categories to shop. For 19” Premium and Rally wheels see the 19” guide. For 20” GT wheels see the 20” guide.

OEM Wheel and Tire Specs

The OEM 18” wheels measure 18x7” with a +47.5mm offset and 5×108 bolt pattern. Both the Select and California Route 1 trims shipped consistently with the same 225/60R18 tire despite having different spoke designs.

Before You Buy

Load index. Use XL-rated tires rated 104 or higher.

EV-specific tires. You do not need a tire marketed specifically for EVs. Choose based on the performance characteristics you want, traction, longevity, efficiency, not the model label.

TPMS. The Mach-E uses direct TPMS with 433 MHz sensors mounted in each wheel’s valve stem. The sensors stay in the wheel during a standard tire swap and are never disturbed by a routine tire change. Do not pay for new sensors on a standard replacement. A valve stem seal inspection is normal and worth doing. After the swap, the system reads pressures automatically on the next drive; no manual calibration step is required.

Tire size. The OEM size is 225/60R18. A move to 235/60R18 is the most natural step up. It is 10mm wider with the same aspect ratio, a better fill on the 7J rim, and a 1.6% increase in overall diameter that falls well within the safe ±3% threshold. The wider contact patch provides a marginal grip improvement without changing the comfortable, high-sidewall character of the 18” setup or adding a large amount of rolling resistance. For other sizes within 3% of OEM diameter, see our 225/60R18 Tire Table.

AWD tire replacement. The Mach-E AWD system uses separate front and rear motors — the two axles are not mechanically coupled. Ford still recommends keeping tread depth difference between axles within 2/32”. If replacing in pairs and the variance between your worn and new tires exceeds that threshold, replace all four. When replacing in pairs, put the newer tires on the rear axle. Rotate every 5,000–7,500 miles to keep wear even.

Grand Touring All-Season

The Michelin Primacy A/S is a Grand Touring All-Season, and this is the typical replacement category for Select and Route 1 owners who want equivalent or better capability. Grand touring all-seasons prioritize long tread life, comfortable road manners, and year-round usability. For the California Route 1 in particular, a trim designed around efficiency, a long-wearing, low rolling resistance all-season is the logical choice.

The Michelin CrossClimate 2 and Continental SecureContact AW earn a 3-Peak Mountain Snowflake rating that the OEM Primacy Tour A/S does not, making them worth considering for owners who see more than occasional snow. Vredestein’s tires test well against higher-priced competitors at a noticeably lower price point and are a strong value pick in this category.

Ultra High Performance All-Season

The 18” wheel and 60-series sidewall are not performance-focused by design, but UHPAS tires still offer a meaningful handling improvement over grand touring all-seasons, with sharper turn-in and more confident wet grip, without requiring a seasonal swap if you only see light snow. Worth considering for owners who want more from the car than the base setup offers.

Summer Performance

Summer tires are not widely available in 225/60R18 or 235/60R18. Visit TireRack to find full availability in 225/60R18 or 235/60R18.

Winter

A dedicated seasonal swap outperforms any all-season in serious winter conditions. The stopping distance gap between a dedicated winter tire and an all-season on ice is significant, and the Mach-E’s weight amplifies that difference. The 18” wheel’s taller 60-series sidewall is particularly well-suited to winter use. More sidewall means better traction compliance on packed snow and ice.

Performance Winter and Snow

Performance winter tires deliver full 3-Peak Mountain Snowflake-rated winter capability while retaining meaningful dry and wet handling. The right choice for owners who want winter grip without sacrificing everything else on the drive to and from winter conditions.

Studless Ice and Snow

Studless ice and snow tires maximize winter traction on ice, packed snow, and in severe cold through advanced siping and compounds that stay pliable at low temperatures. Dry-road handling and tread life are softer than a performance winter, but in genuinely harsh winter conditions these tires make a real safety difference.

Mounting and Installation

A few reminders specific to the Mach-E:

• TPMS sensors stay in the wheel. Do not pay for new sensors on a standard tire swap. A valve stem seal inspection is normal and worth doing.
• Lug nut torque spec: 150 lb-ft. Confirm your installer knows the torque spec and has a properly calibrated torque wrench.
• AWD tread depth tolerance. On AWD variants, replace all four if tread depth differs more than 2/32” between front and rear.
• New tires go on the rear. When replacing in pairs, always put the newer tires on the rear axle regardless of which axle wore first.
