UTV Tire Sizes by Machine

Start With the Size Already on Your Machine

Every tire conversation starts with the same three numbers, molded into the sidewall of the tires already on your machine: overall diameter, width, and wheel diameter — a 30x10-14 is 30 inches tall, 10 inches wide, on a 14-inch wheel. That sidewall is the only completely reliable source for your stock size, because the same machine name covers different trims and years with different factory rubber. Check the front and rear separately: many machines run a narrower front tire than rear from the factory, and a square setup (same size at all four corners) is itself a change worth making deliberately. Once you know your starting point, this page is about the only question that follows: how much bigger can you go, and what does it take?

What One Size Up Actually Buys

Going up one inch of tire diameter gains roughly half an inch of ground clearance, a longer footprint, and an easier roll over rocks, ruts and ledges. It also costs gearing: the machine effectively runs a taller final drive, which you feel as softer response off the bottom, more belt and clutch heat on slow technical ground, and a speedometer that reads low. One step up is invisible to most machines. Two steps is where clearance parts enter the picture, and three steps is where our portal gear lift guide becomes required reading — portals put the gearing back while they lift.

The Biggest Tire Each Machine Clears With Arms We Stock

Forward offset A-arms move the front wheels forward in the chassis, and that extra room is what lets a machine clear a taller tire without rubbing at full lock. The ceilings below are not folklore — each one is the fitment stated on the arm's own listing in this store, so you can read the same number we did before you spend anything.

  • Polaris Ranger XP 1000 — up to 29 inches with Atlas Pro 1.5" forward offset A-arms, which also add 1.5 inches of ground clearance from their high-clearance bends. Working machines usually stop here: it is the size the truck-like Ranger chassis wears best.
  • Polaris RZR XP 1000 — up to 34 inches with Atlas Pro 1.5" forward offset A-arms. That is 32-inch-tire territory with room to spare, or a true 34 for riders who want the extra roll-over.
  • Can-Am Maverick X3 — up to 37 inches with Atlas Pro 2" forward offset A-arms. The X3 has the most headroom of any machine on this page, which is why so many of them end up on 35s.
  • Can-Am Defender — up to 32 inches with 2" high-clearance forward offset A-arms (fitment per the HD7 listing). A 32 on a Defender is the sweet spot for a work machine that also hunts.
  • Polaris General — up to 30 inches with 2" forward offset boxed A-arms. The General's crossover chassis splits the difference between Ranger and RZR, and so does its ceiling.
  • Honda Talon 1000X — up to 32 inches with Atlas Pro 1.5" forward offset A-arms — the size most Talon owners are aiming at for rocky trail systems.
  • Yamaha Wolverine RMAX — up to 34 inches with 1.5" high-clearance forward offset A-arms, a bigger ceiling than most riders expect from the Wolverine platform.

If your machine is not in that list, it does not mean you are stuck at the stock size — it means we have not verified a ceiling against a listing we sell, and we would rather measure twice with you than print a number we cannot stand behind. Contact us with your machine and year and we will work it out from the parts that actually fit it.

Picking the Tire Once the Size Is Set

With a target size in hand, the choice narrows fast. Our 32-inch tire guide and 35-inch tire guide compare everything we stock at the two most popular upsizes, per tire and as sets of four. Terrain-specific shortlists live in the rock crawling guide and the mud tire guide. And if you would rather skip the mounting entirely, our mounted wheel and tire kits arrive ready to bolt on, sized for the machines above.
