Cybertruck Wheel Fitment: The Complete Engineering Guide

What are the stock Cybertruck wheel and tire specs?

Tesla's owner's manual lists a 20 x 9.0J wheel at ET58.5 for every Cybertruck variant, on 285/65R20 all-season or LT285/65R20 all-terrain tires. Long Range and Dual Motor All-Wheel Drive trucks can also have an 18 x 9.0J ET58.5 wheel on 285/70R18 tires. Lug nuts take 151 lb ft (205 Nm) of torque.

The 18-inch wheel has the same 9.0-inch width and ET58.5 offset as the 20-inch, so the offset comparisons below apply to both. Tire comparisons use the 20-inch 285/65R20; the 18-inch 285/70R18 is about 33.7 inches tall by calculation.

Sources: Tesla Cybertruck Owner's Manual, software version 2026.32, North America: Wheel and Tire Specifications for wheels, tires, torque and socket size, and the towing capacity table (PDF, p. 113) for which trims list which wheel. Checked October 1, 2026. The manual does not say which wheel is standard on the trims listed with both. Overall tire diameters are calculated from nominal dimensions. The manual does not print the bolt pattern, center bore or lug thread; those are commonly published aftermarket figures.

What does wheel offset mean on a Cybertruck?

Offset, written ET, is the distance in millimetres from a wheel's rim centerline to its hub mounting face. A higher positive offset pulls the wheel in toward the suspension; a lower one pushes it out toward the fender. Each millimetre of offset change moves both rim lips one millimetre in the same direction.

The factory 20 x 9.0J ET+58.5 wheel has its outer lip 55.8 mm and its inner lip 172.8 mm from the hub face, by the same formulas. Those two figures are the baseline for every comparison below: poke is how much further out an aftermarket outer lip sits, and inner clearance is how much more room its inner lip leaves on the inboard side. All are calculated from nominal dimensions.

How do common 24-inch offsets compare with stock?

Calculated against the factory 20 x 9.0J ET+58.5 wheel, a 24 x 9.5 ET37 sits 27.9 mm further out at the outer lip and leaves 15.2 mm more room on the inboard side. Wider rims and lower offsets push the outer lip further out: a 24 x 10 ET15 sits 56.2 mm further out than stock.

24 x 9.5 ET37 is the Xolaris standard 24-inch specification, set up for a flush stance on the Cyberbeast; every other offset is machined per build. Try any combination in the offset calculator.

Which 24-inch tire sizes stay closest to stock?

Of the common 24-inch sizes, 295/45R24 stays closest to the factory 285/65R20: 34.5 inches tall, 0.4% shorter, calculated from nominal dimensions. A 315/45R24 is 1.6% taller and a 35x12.50R24 about 1.2% taller. The speedometer error matches the diameter change: a taller tire reads low, a shorter one reads high.

Diameter is calculated as rim diameter + 2 × (section width × aspect ratio ÷ 100) ÷ 25.4; flotation sizes such as 35x12.50R24 use their stated diameter, and actual diameter varies by brand and model. A wider section adds width at the tread and sidewall, which uses up room at the fender liner and the suspension before the wheel itself does.

What load rating does a Cybertruck wheel and tire need?

Tesla's owner's manual recommends replacement tires with a load rating equal to or higher than the factory tires, because a lower rating reduces the truck's maximum axle ratings. Check the Tire and Loading Information label on the driver's door pillar. The wheel is rated separately: each Xolaris wheel is rated to 3,600 lb.

A tire with a higher load rating does not raise the axle limits posted on that label, the manual adds, and it says to replace tires with the same load range. A tire's load index is printed on its sidewall after the size; compare it with the factory tire's rather than assuming a larger tire carries more.

Do Tesla TPMS sensors work with aftermarket Cybertruck wheels?

Xolaris wheels are tested and confirmed with the factory Tesla TPMS sensors. Tesla's owner's manual says that after wheels are replaced, the sensors reset automatically once the truck is driven over 15 mph (25 km/h) for longer than 10 minutes.

Until that reset, the manual says, false tire pressure warnings may appear. It also warns that replacement or alternate wheels can stop the TPMS from working properly and says to check the TPMS malfunction light after fitting them, and that a sensor replaced outside a Tesla service center must be a Tesla OEM sensor. If the light stays on after the reset drive, have the sensors checked before relying on them.

Owner threads describe the truck picking up Tesla sensors on its own:

• A Tesla spare wheel with its sensor, rotated onto the truck, showed its pressure on the tire pressure display during the next drive, and the owner confirmed the reading with a gauge. No setup step was described. Owner thread, December 2024
• A winter tire set installed by Tesla service showed accurate pressures on the display, although the service menu's pairing screen never listed the sensors. Owner thread, October 2024

How do you fit 24-inch wheels with a widebody kit?

On a widebody Cybertruck, the wheel offset has to match the flares. A widebody kit moves the fender line outward, so the wheel can sit further out than it should on a stock body, but only by about the flare width. Xolaris machines the offset per build, and quoting one starts with the kit maker's added width per side.

The calculator estimates how much flare is left outboard of the wheel: the kit's added width per side minus the wheel's poke against stock. As an illustration only, a kit adding 50 mm per side over a 24 x 9.5 ET37 with 27.9 mm of poke leaves about 22.2 mm of flare coverage. That is approximate: flare shape and tire sidewall bulge are not modelled.

What we need to quote a widebody set: the flare width over the factory body, per side, in millimetres, from the kit maker; the wheel diameter and tires you want; your trim; and how you use the air suspension.

How does Xolaris set the offset for each build?

Xolaris machines the offset of every set to the truck it is going on. We start from your trim, the diameter and tires you want, how you use the air suspension and whether a widebody kit is fitted, compare the setup with stock the way this guide does, and confirm the offset with you before machining.

Every wheel is machined with a hub-centric 84.1 mm bore held to ±0.02 mm. Lead time is 12 to 14 weeks from project start. The standard specification is 24 x 9.5 ET37; 20 and 22-inch sets are specified per build.
