Fitment
Fits UTVs with a 5x114.3 (5x4.5) bolt pattern and a hub that suits a 68 mm bore, running 15-inch tires.
Wheels fit by bolt pattern, hub bore and offset, not by vehicle name. As a general guide, 4x137 is used on many Can-Am, Honda and Kawasaki machines; 4x156 on Polaris RZR sport models, Yamaha YXZ, Kawasaki Teryx KRX 1000 and Arctic Cat Wildcat XX; and 5x4.5 (5x114.3) on the Polaris RZR Pro R, Pro S and Turbo R and the Kawasaki Teryx H2. Confirm your machine's bolt pattern, hub bore and brake clearance before ordering. Fitment is not guaranteed on unlisted applications.
FAQ
Why run a beadlock wheel?
A beadlock clamps the tire bead so it stays seated at low pressure. MRT says the Machine Gunner's reinforced beadlock keeps the tire locked in under extreme conditions.
What bolt pattern is the Machine Gunner?
5x114.3, also written 5x4.5.
Do I need special lug nuts?
No. MRT lists it as compatible with OEM lug nuts.
Does it come with a center cap?
No. MRT's 5x114.3 center cap (TG5114-CAP) is sold separately.
What offset does it have?
+32 mm with 4+3 backspacing.
Machine Gunner or Tail Gunner?
Both are 15x7, 3-piece forged billet beadlocks. The Machine Gunner is 5x114.3 only with extra machining and a 1,600 lb rating; the Tail Gunner adds 4x137 and 4x156 patterns and is rated to 2,000 lbs.
Why MRT Tires
MRT's wheels come from its Muscle Race Wheels line, built in forged billet, flow-formed, cast and 6061-T6 aluminum constructions with published load ratings and offsets for each size. Dunes 2 Dezert SXS carries MRT wheels alongside MRT tires, so you can build a matched wheel and tire setup from one brand.
