A man choosing between Forged and Cast wheels for his Polaris slingshot

Polaris Slingshot Wheels Buying Guide: Sizes, Tires & Forged vs. Cast

The right set of Polaris Slingshot wheels can bring your entire build together. Rim design, finish and diameter change its appearance immediately, while the tire package and fitment determine how well the upgrade works on your vehicle. Start with the complete package: two front wheels, one rear wheel, the correct tires and the details needed for installation.

This buying guide walks through wheel sizes, forged versus cast construction, tire choices, colors and budget. It also compares the Twist Dynamics Megalodon, Ammonite and Matador options available from Slingshot Only, so you can move from browsing pictures to choosing a set.

1. Choose wheels around your build

Before choosing a spoke design, decide what you want the upgrade to achieve. A coordinated wheel and tire set is an appealing starting point if you want matching styling across all three corners and clearly listed package contents. If you already have a specific tire in mind, verify that it is approved for the wheel width and the vehicle before choosing rims.

  • For a bold visual change: compare the 22-inch Megalodon and Ammonite designs. Their larger wheel faces make the design and color a prominent part of your build.
  • For a lower package price: start with the 20-inch forged sets. The current Megalodon and Ammonite listings include mounted tires and cost less than their 22-inch versions.
  • For a coordinated color theme: compare wheel finishes alongside your body panels, roof frame, seats and brake accents.
  • For driving-focused upgrades: ask about actual wheel-and-tire weight, tire characteristics and fitment. Diameter or the word “forged” alone cannot tell you how a complete setup will drive.

2. 20-inch vs. 22-inch Slingshot wheels

The size on a wheel listing describes its diameter at the tire mounting area. It does not describe the outside diameter of the tire. Width matters too: a 20 × 9 wheel and a 20 × 10.5 wheel share a diameter but accept different tire fitments.

Twist Dynamics offers both Megalodon and Ammonite in the two package configurations below. Each uses wider rear wheels than front wheels.

Package Two front wheels and tires One rear wheel and tire
20-inch forged 20 × 9 wheels
NEXEN 245/30R20 tires
20 × 10.5 wheel
ATLAS 305/25R20 XL tire
22-inch forged 22 × 9 wheels
ATLAS 245/30R22 XL tires
22 × 10.5 wheel
ATLAS 285/25R22 XL tire

Notice the rear tire difference: the listed 20-inch packages use a nominally wider 305 rear tire; the 22-inch packages list a 285 rear tire. A larger rim does not automatically mean a wider tire or more traction.

Compare the whole wheel and tire

Do not assume every 22-inch package has less sidewall than every 20-inch package. In the front sizes above, both tires have a 245 mm nominal width and a 30-series aspect ratio, so their nominal sidewall heights are the same. The larger rim increases the complete assembly’s diameter. These two packages are not simply the same outside tire diameter on different rims.

When changing sizes, check the complete tire dimensions and vehicle compatibility. Michelin explains that changes in tire and wheel diameter can affect gearing, speedometer readings, braking and traction or stability systems. See Michelin’s wheel and tire sizing guidance.

For a daily cruiser, discuss road conditions, ride expectations and replacement tire availability with Slingshot Only. For a show-oriented build, compare how each diameter and finish looks on the vehicle while checking clearance with your existing modifications.

3. Forged vs. cast wheels: what are you buying?

Casting forms a wheel from molten metal in a mold; forging shapes solid material under pressure before further machining and finishing. These are different manufacturing methods, not just different appearances. Compare the specific product specifications and manufacturer documentation before deciding.

For the shopper considering Twist Dynamics, the Megalodon and Ammonite sets are explicitly listed as forged aluminum. That gives you a clearly identified construction type alongside the wheel dimensions, tire package and color choices.

Construction is one part of wheel quality. Compare the specific wheel’s load rating, testing, fitment and actual weight. Avoid assuming every forged wheel is lighter than every cast wheel, or that swapping rims automatically improves acceleration, fuel economy or stopping distance. The tire and the complete assembly matter.

Our buying recommendation: choose Megalodon or Ammonite when you want a Twist Dynamics forged aluminum package with mounted tires and coordinated styling. Choose between them by design, size and finish after confirming fitment.

4. Compare Twist Dynamics wheel packages and prices

The following prices are in USD and were checked on September 15, 2026. Prices, availability and package contents can change; use the linked product page for the current selection.

Wheel set Listed price What makes it worth considering
20-inch Megalodon $2,499.00 Forged aluminum; two front wheels and one rear wheel with mounted tires; three center caps with inserts.
20-inch Ammonite $2,500.00 An alternative forged design with the same listed wheel and tire sizes as the 20-inch Megalodon.
22-inch Megalodon $2,799.00 Larger wheel diameter; forged aluminum; mounted ATLAS tires and three center caps with inserts.
22-inch Ammonite $2,799.00 Ammonite styling with the same listed dimensions and tires as the 22-inch Megalodon.
22-inch Matador Chrome $4,870.38 A separate made-to-order design. Confirm the selected finish, construction and included components before ordering.

Megalodon: choose your diameter, then your color

Twist Dynamics Megalodon forged wheel design for Polaris Slingshot

Megalodon gives you the same design family in 20- and 22-inch versions. The listed 20-inch package is $300 less than the 22-inch package. Both include two front wheels, one wider rear wheel, mounted tires and three matching center caps with inserts.

Compare 20-inch Megalodon wheels and 22-inch Megalodon wheels using the product photos and color selector. Start with the size that fits your build, then choose the finish.

Ammonite: a different design with the same package structure

Twist Dynamics Ammonite forged wheel design for Polaris Slingshot

Ammonite offers another visual direction while retaining the listed front and rear dimensions of the corresponding Megalodon size. At 22 inches, both designs are listed at $2,799. At 20 inches, Ammonite is $2,500 and Megalodon is $2,499, so the design can drive that choice without a meaningful price difference.

View 20-inch Ammonite wheels or 22-inch Ammonite wheels. Compare the spoke design and finish photos rather than assuming one design has a measured performance advantage over the other.

Matador: confirm the details of your custom order

The 22-inch Matador Chrome wheel set is listed separately at $4,870.38, with multiple color combinations and made-to-order production. Its current description does not provide the same detailed tire and component breakdown as the forged packages above. Confirm tires, wheel widths, construction, finish and any required hardware with Slingshot Only before placing the order.

5. Slingshot wheel fitment: check these before ordering

The five wheel listings in this guide currently specify 2015–2024 Slingshots. That is the listed fitment range, not a blanket approval for every modified vehicle. For a 2025 or newer Slingshot, ask the store to verify compatibility before ordering.

  • Model year and trim: provide your exact Slingshot year and model, plus any changes to brakes or suspension.
  • Front and rear positions: confirm the two front wheels and single rear wheel have the correct widths and tire sizes for their positions.
  • Mounting specifications: verify bolt pattern, center bore, offset and compatible lug hardware. Offset describes where the mounting face sits relative to the wheel’s centerline.
  • Brake clearance: disclose factory brake upgrades or aftermarket big-brake kits. Rim diameter alone does not establish clearance around the spokes and caliper.
  • Body and accessory clearance: include fenders, wheel lighting, spacers and lowered suspension in the fitment discussion. Clearance must remain adequate through steering and suspension movement.
  • Tire compatibility: confirm approved wheel widths, load and speed ratings, complete tire diameter, and the suitability of the front/rear combination.

Send the team photos of your current setup if you are unsure what has been changed. Checking these details before ordering is especially useful for a custom-color set.

6. Choose a color and finish that completes the Slingshot

The forged Megalodon and Ammonite listings offer multiple color options. Choices include Gloss Black, Gloss White, Electric Blue, Miami Blue, Nuclear Orange, Lime Squeeze, Pearl Red, Midnight Purple, Titanium Gray and other colors. Check the individual product selector for the full list.

  • Coordinated: choose a wheel color that works with the body and your existing accessories.
  • Contrast: use a different accent color to make the wheels a focal point.
  • Neutral: black, gray or silver can work across multiple accent colors if the rest of your build is still evolving.

Do not select a finish from its name alone. Product photos, lighting and screens can affect how a color appears. If a close match is important, confirm the selected option with the store before the order enters production.

Ask for care instructions for your chosen finish. Use cleaning products approved for that surface, and avoid assuming that a cleaner suitable for one coating is appropriate for chrome, paint or another finish.

7. Budget for the complete upgrade

A useful comparison includes everything needed to get the wheels on your Slingshot. The four Megalodon and Ammonite packages list tires already mounted to the wheels, plus three center caps with inserts. That makes the included components easier to compare than a rim-only price.

  • Confirm shipping and tax for your order.
  • Ask whether balancing, valves, any required sensors and lug hardware are included or additional.
  • Allow for installation and any fitment work identified during the pre-order check.
  • Check replacement tire availability and cost in the selected sizes.
  • Review custom-order terms and confirm the finish before placing the order.

The forged-set listings generally quote a 3–4-week lead time for color options. The Matador listing describes made-to-order production with a 3–4-week in-season lead time. Treat these as estimates and confirm the current schedule if you are planning around a trip or event.

Have a qualified installer check the assembly, clearances and mounting hardware, then use the applicable manufacturer instructions for torque and tire pressure. A mounted tire package still needs a proper installation check.

Frequently asked questions

What are the best rims for a Polaris Slingshot?

The best set is the one that fits your vehicle, budget and styling goals. At Slingshot Only, start with the Twist Dynamics Megalodon and Ammonite forged packages if you want clearly listed wheel dimensions, mounted tires and color options. Choose 20 or 22 inches after reviewing the complete tire size and fitment.

Are Slingshot wheels sold as a set of three?

The Megalodon and Ammonite packages covered here list two front wheels and one rear wheel, with mounted tires and three center caps with inserts. Always check the individual listing; do not assume every wheel product has the same contents.

Do these wheels come with tires?

The four Megalodon and Ammonite sets do, according to their current descriptions. The 20-inch packages list NEXEN front tires and an ATLAS rear tire. The 22-inch packages list ATLAS tires front and rear. Confirm tire inclusion separately for Matador.

Should I choose 20-inch or 22-inch wheels?

Choose based on appearance, price and verified fitment. The 20-inch forged packages start at $2,499; the 22-inch packages are $2,799. Their included tire sizes differ, so do not assume the larger rim is automatically wider, more comfortable or better performing.

Will these wheels fit a 2025 or 2026 Slingshot?

The current product listings specify 2015–2024. Contact Slingshot Only to verify your newer model before ordering. Do the same if your Slingshot has different brakes, lowered suspension or other changes that may affect clearance.

Are forged wheels always lighter than cast wheels?

No. Construction alone does not establish the weight of a particular design and size. Ask for actual wheel and tire assembly weights if reducing weight is a priority, and compare like-for-like sizes and load requirements.

How long do custom-color wheel orders take?

The forged wheel listings generally state 3–4 weeks for color options. Confirm the current production and shipping estimate for your specific order before making plans around an arrival date.
