UTV Wheel & Tire Buying Guide

Quick-start checklist

1. 1Bolt pattern matches your hubs exactly (4x156 for most Polaris, 4x137 for most Can-Am).
2. 2Centerbore is the same size as your hub or larger, so the wheel sits flat.
3. 3Offset / backspacing is close to factory, unless you want a wider stance on purpose.
4. 4Diameter and width suit the tire, and the tire's approved rim width covers the wheel width.
5. 5Front and rear sizes: check whether your machine runs the same wheel at all four corners.
6. 6Lug nuts match your studs (thread and pitch) and the wheel's seat (most alloy wheels need tapered).
7. 7Load rating of the wheel and tire covers your machine's weight and what you haul.
8. 8Clearance the wheel clears calipers, tie rods and A-arms, and the tire clears the fenders at full lock and full compression.

Reading a wheel spec sheet

Every wheel listing should show these specs. Here's what each one means, using a common UTV wheel as the example: 15x7, 4x156, +38 mm offset, 5.50" backspacing, 132 mm centerbore.

Size shorthand: "15x7" is diameter x width. ATV wheels are also often written as backspacing + front spacing, like 4+3 or 5+2 (see Offset and backspacing).

Bolt patterns

The bolt pattern must match the hub exactly. A wheel that is "close" does not fit.

• How to read it: 4x156 means 4 lug studs on a circle 156 mm across. Inches convert at 25.4 mm per inch (4x4.5" = 4x114.3 mm).
• Measuring a 4-lug hub: from the center of one stud straight across to the center of the stud diagonally opposite.
• Measuring a 5-lug hub: from the center of one stud to the back edge of the stud farthest from it, or use a bolt pattern gauge.

• Dual-drilled wheels (4x137 and 4x156 in one wheel) fit both families. Check the centerbore still clears your hub.
• Blank wheels have no lug holes and are drilled to order.
• Adapters can put a wheel with a different pattern on your hub, but they push the wheel out (like negative offset) and need regular torque checks. Treat them as a last resort.

Patterns change between years and trims, and sources don't always agree on newer models. Confirm against your machine or the wheel maker's fitment before you order, or call the shop and we'll check it.

Centerbore and hub fit

The centerbore is the hole in the middle of the wheel. It must be the same size as the raised center of your hub or larger. A bore that is too small stops the wheel from sitting flat, and the lug nuts will never hold torque.

• Bigger than the hub is normal on UTV wheels. The tapered lug nut seats center the wheel. A much larger bore can use a hub-centric ring so the hub carries the load, not just the studs.
• Smaller than the hub never works. Don't bore a wheel out yourself; it voids the wheel warranty.
• Hub sizes vary by model, even within one bolt pattern. Go by the wheel maker's fitment for your exact machine, or measure the raised center of your hub.

Offset and backspacing

Offset decides where the wheel sits: positive pulls it in toward the machine, negative pushes it out. The hub stays put; offset only changes where the wheel sits around it. When in doubt, match the factory offset.

ATV shorthand (4+3, 5+2, 2+5)

The first number is roughly the inches behind the mounting face, the second the inches in front of it.

• 5+2 tucks the wheel in (positive).
• 4+3 is near centered.
• 2+5 pushes it out (negative). It's the common rear setup for ATVs with a solid rear axle, often listed as −47 mm.

Rule of thumb: start from what came on the machine. A little more negative widens the stance. More positive than stock risks hitting the suspension, especially with a wider wheel.

Width, front vs rear, and sets of 4

Most machines run the same wheel at all four corners, but a lot of them run a narrower tire in front and a wider tire in the rear. Some ATVs and side-by-sides run different front and rear wheels too, so check yours before you order a "set of 4".

Width

• UTV wheels are usually 7 to 10 inches wide; 7 inches is the most common.
• The wheel should be narrower than the tire, by up to about 4 inches, and inside the tire maker's approved rim width.
• Wider isn't free. At the same offset, a wider wheel puts more rim on the inside and the outside, so it can hit suspension parts a 7-inch wheel clears.

Diameter

• ATVs usually run 10- to 12-inch wheels and UTVs 12- to 15-inch. Lifted and sport machines go to 15 inches or more.
• 18- to 24-inch wheels are for show and street builds with low-profile tires, not for mud or rocks.

Front vs rear (staggered)

• Tires: front and rear sizes often differ even when the wheels match, so check both sidewalls.
• Wheels: some machines come stock with a narrower front and a wider rear wheel, for example 7 inches front and 8 to 10 inches rear, often with different offsets (like 4+3 front, 2+5 rear).
• If your machine came staggered, buy 2 front and 2 rear, each in its own size and offset.

A full set includes

• 4 wheels
• The correct lug nuts: 16 for 4-lug, 20 for 5-lug, 24 for 6-lug
• Center caps, if they're sold separately
• Valve stems, if they aren't already installed

Lug nuts

New aftermarket wheels almost always need new lug nuts. The thread must match your machine's studs, and the seat must match the wheel.

1. Thread size and pitch, written as diameter x pitch: 10x1.25, 12x1.25, 12x1.5 or 3/8-24. This comes from your machine's studs.
2. Seat type, which comes from the wheel. Never use a flat or ball seat on a tapered-seat wheel.
3. Drive style. Narrow lug holes on many aftermarket wheels need a spline-drive nut, which takes a spline key instead of a normal socket. Check a socket fits before choosing a hex nut.

Typical threads by make

Years and models vary, so treat this as a starting point. To confirm, check the owner's or service manual, use a thread pitch gauge on a stud, or try a known nut by hand: it should spin on easily for several turns. Never force it.

Torque and re-torque

• Torque in a star pattern to the machine maker's spec, by hand with a torque wrench. Don't run them on with an impact gun.
• Re-check torque after the first ride (roughly the first 25 to 50 miles). Aluminum wheels seat in, and nuts can loosen.
• Re-check again after any tire change and after hard use.

Wheel spacers

A spacer bolts to the hub and pushes the wheel out, which works the same as running more negative offset. A 1.5-inch spacer moves each wheel out about 1.5 inches and widens the track about 3 inches per axle.

• Why people use them: more stability, a wider look, clearing a big brake or suspension part, or making a too-positive wheel fit.
• What it costs you: the same trade-offs as negative offset. More leverage on wheel bearings, ball joints and tie rods, heavier steering, and tires that can hit the fenders.
• Match three things: the bolt pattern, your hub's center, and the thread of the studs the spacer adds.
• Install right: torque the spacer to the hub first, then the wheel to the spacer, and re-check both after the first ride. Never stack spacers.
• Buying new wheels? Choose the offset you want instead of adding spacers to the wrong wheel.

Tires

The tire must match the wheel's diameter exactly, and the wheel's width must sit inside the tire's approved rim width.

Radial vs bias

• Radial: smoother ride, cooler running, better on hardpack and at speed. Most modern UTV tires are radial.
• Bias: stiffer sidewall, often cheaper, common on ATVs and work tires.

Ply rating and load

• Ply rating (6-ply, 8-ply, 10-ply) is a strength rating, not a literal count. Higher resists punctures and carries more, but rides stiffer and weighs more.
• Load index / max load is the most each tire can carry (load index 81 is about 1,020 lbs). Times 4, it should beat your machine's loaded weight, including cargo and towing.
• Speed rating (for example J) is the top sustained speed the tire is rated for. Match or beat your machine's top speed.
• D.O.T. approved matters if your machine is street-legal where you ride.

Going taller: what changes

• Clearance: taller tires may rub at full lock and full compression; some machines need a lift kit.
• Power and clutching: a taller tire acts like taller gearing. It works the belt and clutches harder, and bigger jumps in size may need a clutch kit.
• Speedometer: it reads low by about the percent the tire is taller. Going from 30 to 32 inches reads about 7% slow.
• Wear on parts: heavier, taller tires put more load on axles, wheel bearings and ball joints.

Wheel construction and features

Cast aluminum is the value choice, forged is the strongest and most expensive, and beadlocks are for low tire pressure in mud, rocks and sand.

Beadlocks

• A true beadlock clamps the tire's outer bead between the wheel and a bolted ring, so the tire stays seated and won't spin on the rim at very low pressure. The ring bolts need regular torque checks, and true beadlocks aren't D.O.T. approved for street use.
• A simulated beadlock has the look of a ring but holds the tire like a normal wheel. Check the listing to see which one you're getting.

Weight, finish and warranty

• Wheel weight is unsprung weight. Lighter wheels help acceleration, braking and suspension response.
• Finishes include gloss and matte black, machined, polished, bronze and colors. Machined and polished faces show scratches and corrosion more.
• Check each wheel's structural and finish warranty; they differ by brand and wheel.
• Load rating: many UTV wheels are rated around 1,500 lbs each. Heavy work and towing machines should check this number.

What changes when you change wheels and tires

Bigger, wider and further-out setups look and ride great, but they put more load on the parts between the hub and the frame. Budget for that.
