Ford Explorer ST (2020-2027) Wheel Fitment Guide
Every 2020–2027 Explorer ST uses a 5×114.3 bolt pattern, a 70.5mm center bore and M14×1.5 lug nuts with a 60° conical seat. Factory wheels are 20×8.5 ET44.5 (2020–2024 standard) and 21×9 ET37.5 (Street Pack, then standard from 2025). This guide covers tire-height limits at full lock and why every setup stays square.
About this guide: Fitment data is compiled from owner builds on ExplorerST.org and in owner-submitted fitment galleries, cross-checked against the factory specs below. Use it as research for your build; ride height, tires, and alignment are still your installer's call.

OEM Setups
Factory Wheel & Tire Configurations
The 2020–2024 ST came on a 20″ wheel as standard, with a 21″ wheel and larger brakes in the Street Pack and High Performance Package. The 2025 refresh made the 21″ size standard, and the 2027 Sinister Package adds a gloss-black 21″ design. The body and hub never changed.

A 2027 package wheel in gloss black, on the same 275/45R21 tire as the standard wheel. Ford has not published its width or offset; if your car has it and you want to match its fit, check the stamp on the back of a spoke before ordering.
Aftermarket Options
Aftermarket Wheel & Tire Configurations
Each card below is one wheel size, and each row is one documented owner build at its effective offset. Spacer builds are listed at the offset we would machine into the wheel. Front and Rear figures show how far each lip sits outside the factory 21×9 ET37.5 wheel.
Tap a setup to jump to its full card. Fit: Bolt-on = documented at stock ride height with no fender work reported · Lowered = documented on lowering springs or coilovers · Not reported = owners didn't say. Sources = owner builds (including customer cars in vendor galleries) and vendor fitment-guide setups documented on that card.
On 22×10.5 wheels around ET30, a 305/35R22 clears with margin, while a taller 305/40R22 is documented with light rubbing at full steering lock, more often on lowered cars. Owners keep overall diameter close to the factory 30.7–31″; 22×11 fronts are reported to rub the liner at any offset from ET25 to ET35.
Brake clearance.
The performance brakes on the Street Pack, HPP and 2025+ ST clear common 20″ and larger aftermarket wheels, but spoke shape matters as much as diameter. FMB checks caliper clearance for your brake package before forging.
4WD rolling diameter.
Staggered configurations can produce front-to-rear rolling diameter mismatches that may stress the Explorer's 4WD system over time. The math should be checked against your owner manual before committing — we document tire dimensions on every card; verifying compatibility is your responsibility.

The Explorer ST's signature setup, built by more owners than any other size. ET30 sits flush with the fender and is where most builds land; ET32 is a touch more conservative. A 305/35R22 clears with margin; a 305/40R22 fills more sidewall but several owners report light rub at full lock, so start with the 305/35 rows if your car is lowered.

A 20″ option that keeps more sidewall for ride comfort. Owners run ET32 to ET40 on 285/50R20 or 295/45R20 tires, close to the factory 30.7″ diameter. One build reaches its offset with 5mm spacers on Eibach springs.

Keeps the factory 21″ diameter with the same 10.5″ width and ET30 offset owners use on 22s, on a 295/40R21 tire. Documented on two owner cars, one switched from the 22″ setup.

Was this guide helpful?
Let us know how we did on Google.
Your feedback helps other owners find these free fitment guides. It takes about 30 seconds.
Built to the exact spec, not the closest one on a shelf. The setups above come from real Explorer ST builds, and we CNC-machine every wheel to them directly. If a build needs a spacer to reach its offset, we machine that offset into the wheel instead.
Choose your setup.
This guide is built to give you what you need to pick a spec with confidence: documented Explorer ST builds, tire sizes, and how each one fits. If you still have questions, we're happy to help before you order.
Engineering verification.
Our manufacturing partner confirms wheel specs, including bolt pattern, center bore, brake caliper clearance, backspacing and load rating.
Render approval.
You approve the design and final specs before we move forward with production.
Our fitment guarantee
Every set is guaranteed to mount on your Explorer ST: 5×114.3 bolt pattern, bored to the 70.5mm hub, machined for 60° conical lug nuts, and made to the exact width and offset you approved.
How a setup sits on your car also depends on ride height, tires and alignment, so choose with your plans in mind.
The 2020–2024 ST came standard on a 20×8.5 ET44.5 wheel with 255/55R20 tires, with a 21×9 ET37.5 wheel on 275/45R21 in the Street Pack and HPP. That 21″ size became standard for 2025–2027, and the 2027 Sinister Package adds a gloss-black 21″ design. Every factory setup is square.
What are the Explorer ST's bolt pattern, center bore and lug torque?
Every 2020–2027 Explorer ST uses a 5×114.3 bolt pattern, a 70.5mm center bore and M14×1.5 lug nuts with a 60° conical seat, torqued to 150 lb-ft (204 Nm). FMB bores every set to the 70.5mm hub, so no hub-centric rings are needed.
What aftermarket sizes fit the Explorer ST at stock ride height?
Owners running aftermarket wheels at or near the factory specs typically report no clearance changes at stock ride height. The most documented stock-height builds are 22×10.5 at ET30–ET32 on 305/35R22 or 305/40R22, and 20×9 to 20×9.5 at ET30–ET40. A 305/40 is where light full-lock rubbing reports start.
How do I read the offset rows, and what separates flush from aggressive?
Each card is one wheel size; each row is one documented build at its effective offset. The Front and Rear figures show how far each lip sits outside the factory 21×9 ET37.5 wheel. On the Explorer ST, about 25–27mm out (22×10.5 ET30) is flush with the fender; much past that and the tire starts to poke.
Will aftermarket wheels clear the Explorer ST's brakes?
Usually, at 20″ and up. Owners report 20″ aftermarket wheels clearing the larger Street Pack and 2025+ performance brakes, but spoke shape matters as much as diameter: a flat face near the caliper can contact where a curved spoke clears. FMB checks caliper clearance for your brake package before forging.
Should I run a square or staggered setup on my Explorer ST?
Square. The ST is four-wheel drive, and matching front and rear tire sizes keeps rolling diameter equal so the 4WD system is not stressed. Every card on this page is square; the one staggered owner build we found is not listed. Square also lets you rotate tires.
Do I need spacers on the Explorer ST?
Not with the right offset. Some owners use spacers to push a wheel out; every spacer build on this page is listed at its effective offset, so ET37 plus 5mm shows as ET32, because FMB machines that face position into the wheel. Spacers also need longer studs or lug nuts.
What winter wheels can I run on the Explorer ST?
Owners use 20″ winter sets, such as 20×9 on 275/50R20 or the factory 20×8.5 ET44.5 wheel on 255/55R20. Those keep tire height near stock and clear the brakes on documented cars. Check spoke clearance for your brake package before buying a winter set.
Do I need TPMS sensors in new Explorer ST wheels?
Yes. The Explorer uses direct TPMS sensors mounted in each wheel, so a new set needs sensors moved over or new compatible sensors. Most tire shops can relearn them to the vehicle during installation.
Which Explorer ST model years does this guide cover?
All of them: 2020–2027. The 2025 refresh made the 21×9 ET37.5 wheel standard but did not change the body, hub or wheel wells, so every card applies to every ST. The 10th VIN character gives the model year: L through R is 2020–2024, S, T or V is 2025–2027.
Will Explorer ST wheels fit other 2020+ Explorers?
Yes. Every 2020+ Explorer shares the 5×114.3 bolt pattern, 70.5mm hub and M14×1.5 lug nuts, so ST wheels bolt on to an XLT, Limited, Platinum or Timberline. Base trims have smaller brakes, so clearance is easier; the Timberline's taller tires change what fits at the fender.
