Tesla Model Y Juniper (2026–Present) Wheel Fitment Guide
The 2026 Model Y Juniper uses a 5×114.3 bolt pattern, a 64.1mm center bore and M14×1.5 lug nuts with a 60° conical seat. Premium wheels are 9.5″ wide at ET45, Standard runs an 18″ ET38 steel wheel, and Performance a staggered 21″ set. This guide covers the Performance brakes and lowered-car clearance.
About this guide: Fitment data is compiled from owner builds on Tesla Motors Club and vendor-built Juniper cars in wheel-maker galleries, cross-checked against Tesla's service manual and vendor fitment documentation. Use it as research for your build; ride height, tires, and alignment are still your installer's call.

The 2026 Model Y comes on four factory wheels: an 18″ steel wheel on Standard, the 19″ Crossflow or optional 20″ Helix 2.0 on Premium, and the staggered 21″ Arachnid 2.0 on Performance. Tesla's service manual is the source for every size and offset below.

Platform-specific fitment notes — Model Y Juniper
Performance brakes and smaller wheels.
Tesla lists its 19″ Crossflow winter package as not compatible with Model Y Performance, yet two 2026 Performance owners report the factory 19×9.5 ET45 wheel fitting with no rubbing, and vendor builds include 18″ and 19″ sets on Performance cars. Spoke shape decides caliper clearance, so FMB checks it for your trim before forging.
Lowered cars and spacer builds.
The most outboard rows here, ET12 to ET20 at 19″ and 20″, are vendor builds on lowering springs with spacers. At stock height, most documented Juniper builds sit between the factory line and about 12mm out. Check fender clearance before going further out on a lowered car.
Lug nut seat and shoulder.
Tesla's M14×1.5 lug nuts have a 60° conical seat and a 21mm hex. FMB machines the seat to fit; if your new wheels use a smaller lug pocket, use matching conical nuts rather than forcing the factory ones.

Our Process
What happens when you build with FMB
Built to the exact spec, not the closest one on a shelf. The setups above come from real Model Y 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 Model Y 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 Model Y: 5×114.3 bolt pattern, bored to the 64.1mm 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.

FAQ — Frequently Asked Questions
What wheels and tires come stock on the 2026 Model Y Juniper?
Model Y Standard uses an 18×8.5 ET38 steel wheel on 235/55R18. Premium cars get the 19″ Crossflow (19×9.5 ET45, 255/45R19), with the 20″ Helix 2.0 (20×9.5 ET45, 255/40R20) optional. Performance cars use the staggered 21″ Arachnid 2.0: 21×9.5 ET40 front and 21×10.5 ET48 rear on 255/35R21 and 275/35R21.
What are the Model Y Juniper bolt pattern, center bore and lug nuts?
The Juniper keeps the 5×114.3 bolt pattern and 64.1mm center bore, with M14×1.5 lug nuts that have a 60° conical seat and 21mm hex, torqued to 129 lb-ft (175 Nm). FMB bores every set to the 64.1mm hub and machines the seat for conical nuts.
What aftermarket sizes fit the Model Y Juniper at stock ride height?
Owners running aftermarket wheels at or near the factory specs typically report no clearance changes at stock ride height. Most documented Juniper builds are 18×8.5 to 20×9.5 at ET30 to ET45, within about 12mm of the factory lip. Owner data on the Juniper is still thin, so many rows here are vendor builds.
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 19×9.5 ET45 Crossflow wheel. On the Juniper, under about 10mm out still looks close to stock; 15–25mm out reads flush to aggressive.
Do aftermarket wheels clear the Model Y Performance brakes?
Tesla lists its 19″ Crossflow winter package as not compatible with Performance, but owners report the factory 19″ wheel fitting a 2026 Performance, and vendor builds include 18″ and 19″ sets on Performance cars. Spoke and barrel shape decide caliper clearance, so FMB checks it for your trim before forging.
Should I run a square or staggered setup on the Model Y Juniper?
Most documented Juniper builds are square, which lets you rotate tires; only the Performance comes staggered from the factory. Staggered 21″ sets are documented on vendor builds. Dual-motor cars are all-wheel drive, so keep front and rear rolling diameters close; we list tire sizes on every card, and your owner's manual is the check.
Do I need spacers on the Model Y Juniper?
Not with the right offset. Some vendor builds use 15–20mm spacers on lowered cars; every spacer build on this page is listed at its effective offset, because FMB machines that face position into the wheel. Two rows here, ET17 / ET12 at 19″ and ET20 at 20″, come from spacer builds.
Do I need new TPMS sensors for aftermarket Model Y Juniper wheels?
The Juniper uses Tesla's Bluetooth Low Energy (BLE) TPMS sensors, so generic 433 MHz sensors will not work. Move the factory sensors to the new wheels or buy Tesla-compatible BLE sensors; the car pairs them after a short drive. Set the matching wheel configuration in the car's settings so range and tire alerts stay accurate.
How do wheel size and winter sets affect Juniper range?
Smaller wheels with taller, narrower tires are the most efficient; 21″ and 22″ sets with wide summer tires cost the most range. Owners chasing range or a winter set commonly run 18×8.5 on 235/55R18 to 245/50R18. Tesla's 19″ winter package suits Standard and Premium cars. Before-and-after range data on specific setups is limited.
Which Model Y cars does this guide cover, and how do I tell a Juniper?
This guide covers the refreshed Model Y (Juniper), sold in the US as model year 2026, in Standard, Premium and Performance trims. Check VIN position 10: T is 2026, while L through S are the original 2020–2025 Model Y, covered in its own guide. The three-row Model Y L uses different wheels and is not covered here.
Can I use original Model Y or Model 3 wheels on a Juniper?
Original 2020–2025 Model Y wheels share the 5×114.3 pattern, 64.1mm bore, lug nuts and the same 9.5J ET45 at 19″ and 20″, so they bolt on. Model 3 wheels also bolt on, but their tires are smaller in diameter and may lack the load rating a Model Y needs. Tesla does not list Model 3 wheels for Model Y.
