Ford Explorer ST (2025+) Wheel Fitment Guide
The 2025 Ford Explorer ST is a midcycle facelift of the rear-wheel-drive U625 platform — same 3.0L EcoBoost twin-turbo V6, same AWD architecture, same core suspension geometry. The most significant change for wheel fitment: the 21×9 ET37.5 wheel is now the standard equipment on every ST, replacing the 20″ wheel as the base configuration. A new 15-spoke Dark Grey style replaces the previous 7-spoke design. Because the underlying platform is unchanged, the entire aftermarket fitment knowledge base built by the 2020–2024 ST community applies directly to the 2025 model.
Our flush fitment options are designed to work without rubbing while maintaining proper clearance and everyday drivability.
Factory Wheel & Tire Configurations
The 2025 Explorer ST comes standard on a new 21-inch 15-spoke wheel — a departure from the 2020–2024 model where 21″ wheels required an optional package. All base hardware specs (bolt pattern, center bore, thread pitch, torque, and seat type) are unchanged from the previous generation.
Aftermarket Wheel & Tire Configurations
The 2025 Explorer ST shares its platform, suspension, and clearance geometry with the 2020–2024 model. Every aftermarket fitment confirmed on the earlier generation applies directly to the 2025. The setups below are drawn from the established 2020–2024 ST owner community on ExplorerST.org and ExploreForum.com — the same builds, the same clearance thresholds, the same confirmed combinations. As 2025-specific builds accumulate, this section will be updated accordingly.
Inner Suspension Clearance: Know Your Offset Limit The 2025 Explorer ST shares its platform and suspension geometry with the 2020–2024 model. At stock ride height, there is less than ½" between the front tire inner barrel and the suspension at full steering lock. On wide aftermarket wheels, offset matters more than diameter. On a 10.5"-wide wheel, ET30 is the proven minimum for clean fitment — anything below ET30 risks contact with the front sway bar or shock. ET25 on a 10.5" wide wheel with a 305/40 tire has been confirmed to rub on the pre-facelift platform, and the same geometry applies here. On the outer side, 305/40 on a 10.5" wheel at ET30 may lightly contact the front fender liner at full steering lock — 305/35 clears completely.

FAQ - Frequently Asked Questions
The 2025 Explorer ST comes standard with 21×9 ET37.5 15-spoke Dark Grey aluminum wheels (Ford part number RB5Z-1007-D, indent RB5C-1007-G1A) wrapped in 275/45R21 Pirelli Scorpion Zero A/S tires. Unlike the 2020–2024 model where 21-inch wheels required an optional Street Pack, the 21″ wheel is now standard on every 2025 ST.
The 2025 is a facelift of the same U625 platform — the suspension geometry, bolt pattern, center bore, thread pitch, and torque spec are all unchanged. The key difference is that the 21×9 ET37.5 wheel is now standard equipment instead of requiring the ST Street Pack upgrade. The wheel style itself changed from a 7-spoke gloss black design (LB5Z-1007-F) to a new 15-spoke Dark Grey design (RB5Z-1007-D). The 20×8.5 ET40 standard wheel from the 2020–2024 model is no longer part of the ST configuration.
Bolt pattern is 5×114.3 (also expressed as 5×4.5″). Center bore is 70.5mm. Lug nuts use M14x1.50 thread pitch with a 60-degree conical seat. Torque specification is 150 lb-ft (204 Nm). These specs are unchanged from the 2020–2024 generation.
Yes. The 2025 Explorer ST shares the same platform, suspension geometry, and clearance envelope as the 2020–2024 model. Every aftermarket fitment confirmed on the earlier generation applies directly to the 2025. The inner suspension clearance thresholds, offset limits, and tire size guidance are identical.
On a 10.5″-wide wheel, ET30 is the confirmed minimum for clean fitment. Below ET30, the inner barrel of the tire begins to encroach on front suspension components. At ET25 on a 10.5″ wide wheel with a 305/40 tire, contact with the front sway bar or shock has been confirmed on this platform at full steering lock. On the outer side, 305/40 on a 10.5″ wheel at ET30 may lightly contact the front fender liner at full steering lock — 305/35 clears completely.
The dominant setup confirmed across the 2020–2024 ST community — which applies directly to the 2025 — is 20×10.5 ET30 with 295/45R20 tires. This keeps overall diameter close to OEM (no speedometer correction needed) and has been confirmed clean by multiple owners. The 22×10.5 ET30 with 305/35R22 is the second most popular choice, preferred by owners who want larger-diameter visual impact.
The Explorer ST hub bore is 70.5mm. Most aftermarket wheels are drilled to 72.6mm or 76.1mm. If your wheel’s center bore is larger than 70.5mm, polycarbonate or aluminum hub-centric rings are required to properly center the wheel. Always verify your wheel’s center bore before ordering.
The Explorer ST uses M14x1.50 thread pitch lug nuts with a 60-degree conical seat. Many aftermarket wheels use a ball-seat or flat-seat design, which requires matching aftermarket lug nuts. The OEM conical nuts will not seat correctly in a ball-seat wheel. Always verify the seat type your aftermarket wheel requires before purchasing lug hardware.
All confirmed aftermarket fitments on the Explorer ST platform are square — the same size all four corners. The OEM configuration is also square. Square setups allow tire rotation across all four corners, are simpler to source, and are how this platform is universally run by the aftermarket community.
The OEM 21×9 ET37.5 wheels pair well with winter-specific 275/45R21 tires — Nokian Hakkapeliitta R3 SUV and Michelin X-Ice Snow have been used successfully by ST owners on this rim size. Alternatively, a dedicated 18″ or 19″ steel wheel with a 255/65 or 265/60 winter tire gives a taller sidewall and better snow traction at lower cost per season. Narrower tires typically outperform wide low-profile setups in snow — the OEM 275 width is already wide enough that a step down for winter is worth considering in serious snow climates.
