Metal FX Mayhem R Beadlock Gloss Silver Machined 15" UTV Wheel 5x4.5

The Metal FX Mayhem R Beadlock in Gloss Silver Machined is a true beadlock UTV wheel for the Polaris RZR Pro R, RZR Turbo R, RZR Pro S and XPedition, built on a 5x114.3 (5x4.5) bolt pattern in 15x8 and 15x10. It pairs a cast aluminum wheel with a Gloss Silver Machined finish for a bright, metallic look.

Running lower tire pressure for traction means a tire is more likely to unseat. The Mayhem R uses a functional beadlock ring that clamps the outer bead to the wheel, so you can air down for dunes, desert and moderate rocks with the bead held in place. If you are shopping RZR Pro R wheels or Polaris XPedition wheels and want true beadlock hardware rather than a simulated ring, this is one of the Metal FX RZR wheels built for that job. Among UTV beadlock wheels for 5-lug Polaris machines, the Mayhem R pairs a cast A356-T6 aluminum wheel with a forged 6061-T6 ring in 15x8 and 15x10 widths.

Key Features

• True beadlock: a functional ring mechanically clamps the tire's outer bead
• 5x114.3 (5x4.5) 5-lug bolt pattern with a 66.1mm center bore

Built To Solve: Tires Unseating at Low Pressure on 5-Lug Polaris UTVs

• Tires rolling off the bead when aired down for traction
• Stock wheels without beadlock hardware for low-pressure riding
• A 5-lug Polaris build that needs a wheel matched to its 5x114.3 hub
• Polaris RZR beadlock wheels made for 4-lug RZR models that will not bolt onto a 5-lug Pro R, Turbo R or Pro S
• Choosing a width without knowing the offset and backspacing

Best For: RZR Pro R, Turbo R and XPedition Owners Who Air Down

• RZR Pro R and RZR Pro S owners shopping RZR Pro R beadlock wheels, and Turbo R owners comparing RZR Turbo R wheels
• Polaris XPedition and Ranger XD 1500 owners looking for Polaris beadlock wheels on the 5-lug hub
• Riders searching for 5x4.5 beadlock wheels, 15 inch, who need a UTV fitment rather than a truck wheel
• Riders who drop tire pressure for dunes, desert and moderate rocks
• Builders choosing between a 15x8 and a 15x10 for their tire size
• Can-Am Maverick R owners should look at the 6-lug Mayhem 6R instead

FAQ

Will the Metal FX Mayhem R fit my Polaris RZR Pro R?

Yes. The Mayhem R uses the 5x114.3 (5x4.5) bolt pattern of the RZR Pro R, RZR Turbo R, RZR Pro S and RZR XP S, including their 4-seat versions. It also fits the Polaris XPedition and Ranger XD 1500, Kawasaki Teryx H2, Segway Super Villain and CFMoto UForce U10 Pro. Confirm overall width with your chosen tires before ordering.

What sizes and offsets does the Mayhem R come in?

Two sizes in Gloss Silver Machined: 15x8 at +0mm offset (4+4 backspacing), and 15x10 at +0mm offset (5+5 backspacing). Center bore is 66.1mm.

Is the Mayhem R a true beadlock?

Yes. It uses a functional beadlock ring that mechanically clamps the tire's outer bead to the wheel, which helps keep the tire seated at lower tire pressures.

What bolt pattern does the RZR Pro R use?

The RZR Pro R uses a 5-lug 5x114.3 pattern, also written 5x4.5, which is the pattern the Mayhem R is drilled for. Older 4-lug RZR models use a different pattern, so a 4-lug RZR wheel will not fit.

Should I run the 15x8 or the 15x10?

Both sit at +0mm offset. The 15x8 (4+4) is the narrower option; the 15x10 (5+5) is wider and changes overall vehicle width, so check it against your tires and how you plan to use the machine.

What do I need to install the Mayhem R?

The Mayhem R takes acorn-style lug nuts, sold separately. On the RZR Pro R, Turbo R, XPedition and Ranger XD 1500, the Valor Offroad 12x1.5 5-lug kit fits. Metal FX also states that the mud scrapers must be removed before installing these wheels to avoid damage, and publishes mud scraper removal instructions, linked on this page.

Why Metal FX

Metal FX wheels are built with platform-specific fitment: the Metal FX UTV wheels in the R line are laid out around Polaris's 5-lug platforms, with a matching 6-lug 6R line for the Can-Am Maverick R. The Mayhem R pairs a cast A356-T6 aluminum wheel with a forged 6061-T6 beadlock ring. The Mayhem R also comes in Gloss Black and Gloss Black Contrast Cut. Gloss Silver Machined is the bright option in the range, a metallic silver alternative to a blacked-out setup.

Complete Your 5-Lug Polaris Beadlock Wheel Setup

Pick your width, 15x8 or 15x10, then match a tire size and check overall width before you order the Mayhem R Gloss Silver Machined. Add an acorn-style lug kit, such as the Valor Offroad 12x1.5 5-lug kit for Polaris, and plan to remove the mud scrapers at install.
