24X9-11 Tire Size

24x9-11 ATV Tires: Front Fitment, Control & Replacement Options

24x9-11 is a front ATV tire measuring 24 inches in diameter, 9 inches wide, and designed for 11-inch rims. It occupies a specific middle position in the front tire range - one inch wider and one inch taller than the more common 23x8-11, but still narrow enough to keep steering input manageable where a 10-inch front would start to work against the rider. That balance is why the 24x9-11 size exists as a distinct OEM fitment.

4x9-11 is most commonly paired with 24x10-11 rear tires. The matched 24-inch diameter is what drives this pairing - keeping front and rear heights equal maintains level chassis geometry and correct AWD engagement on systems calibrated for diameter consistency across axles. 

Most buyers searching for 24x9-11 size are replacing a worn front on a machine that came with matched 24-inch front-and-rear diameters from the factory.

Vehicles Using 24x9-11 Tires

24x9-11 appears most often on platforms where the manufacturer specified matched 24-inch diameters front and rear - a design choice that prioritizes AWD consistency and chassis balance over the narrow-front/wide-rear stagger common on trail-focused machines.

Common Applications

• Yamaha Grizzly 450 / Kodiak 450 - front fitment on configurations running matched 24-inch diameter front and rear
• Honda Foreman 500 / FourTrax Rancher - utility setups where the OEM front diameter is 24 inches
• Polaris Sportsman 500 - front axle on models specifying a 9-inch-wide front tire
• Can-Am Outlander 570 - utility trims running this size as the factory front fitment

Front vs. Rear Use: Is 24x9-11 a Front or Rear Tire?

24x9-11 is a front-specific tire size. Nine inches of section width sits at the practical upper limit for front tires on most utility ATVs - wide enough to generate meaningful grip and stability improvements over narrower front alternatives, but not so wide that turning radius and steering effort become problems in tight terrain. One inch beyond this, and you are typically into rear tire territory on machines in this class.

Why the Width Works on the Front

The difference between a 9-inch and an 8-inch front tire is not just a number. An inch of additional section width expands the contact patch measurably - on loose or transitional terrain, that extra surface area is what keeps the front end planted through direction changes rather than washing wide. 

At the same time, 9 inches still allows the tire to track through narrow ruts without the front axle fighting the channel walls the way a 10-inch front sometimes does. It is genuinely the right width for a front tire on a machine doing serious mixed terrain work at normal utility speeds.

Recommended Front-to-Rear Pairing for 24x9-11

The 24x11-10 and 25x10-12 pairings involve different rim diameters front and rear. You cannot run these combinations on the same wheel set; separate front and rear wheels are required. Confirm your rim inventory before selecting either option.

The primary pairing - 24x9-11 front with 24x10-11 rear - is the one this size was built around. The one-inch width difference between front and rear maintains the traction stagger that utility ATV drivetrain design depends on, while the matched diameter keeps AWD engagement clean. Deviating significantly from this ratio is where handling problems and premature drivetrain wear tend to start.

24x9-11 Tire Size Explained

24x9-11 uses the flotation sizing format standard across ATV and off-road tires, meaning:

• 24 - overall tire diameter in inches
• 9 - section width at the widest point in inches
• 11 - wheel/rim diameter in inches

The 24-inch diameter puts the 24x9-11 tire one inch taller than a 23x8-11 front - a difference that modestly improves obstacle rollover and ground clearance without pushing gearing ratios outside the range factory calibrations expect.

The 9-inch width is the defining characteristic of the 24x9-11 size. It is wide enough to be a genuine performance step up from 8-inch fronts in grip and stability, but it does not enter the territory where wider front tires start to compromise the steering geometry they are supposed to protect. The 11-inch rim is standard across the front wheel specifications of most utility ATV platforms running a 24-inch front diameter.

4-Ply, 6-Ply, or 8-Ply: Which is Better for 24x9-11 Front Tire?

For a 24x9-11 front tire, the correct ply rating depends on whether you prioritize steering feel or armor-like durability. While rear tires use higher ply for traction and load, the front axle uses ply to dictate sidewall stiffness, which directly controls steering precision and handlebar feedback.

Recommended PSI for 24x9-11

Most 24x9-11 front tires run best at 5-7 PSI. At 5 PSI, the sidewall has enough flex to conform to loose and uneven terrain - the contact patch expands and the tire grips rather than bouncing over surface irregularities. 

At 6-7 PSI, the sidewall firms up enough to resist lateral flex at speed and on hardpack, where precision matters more than compliance. 

Where 24x9-11 Tires Perform Best

The 24x9-11 is often the first performance upgrade for riders moving away from a standard 23x8-11 front tire. It is a "size-up" that prioritizes front-end stability and predictability over raw speed.

Trail & Hardpack: Better Tracking

This 9-inch width solves the "sliding" feel common in sharp corners with the 8-inch width. On groomed trails, the extra rubber 24x9-11 prevents the front end from pushing (understeering) when you change lines quickly. Additionally, the 24-inch diameter offers a better "rollover angle" than 23-inch tires, meaning you’ll feel less of a jolt when hitting roots or trail debris.

Mixed Terrain: Consistent Transitions

The 24x9-11 provides a wider contact patch than 8-inch tires, staying composed when moving from packed gravel to soft dirt. Workhorse tires like the Carlisle AT489 thrive here because their tread spacing is wide enough to clean out mud but tight enough to stay smooth on the hard stuff.

Utility & Loaded Handling

The 24x9-11 wide front tire is the specific mechanical fix for the "vague" steering feel that happens when an ATV is loaded down in the back. On utility quads, heavy rear cargo or trailers unweight the front axle, reducing the downward pressure needed for the tires to "bite" the ground. The 24x9-11 compensates for this light front end by providing a larger contact patch, ensuring the machine stays responsive and predictable even when the front suspension is barely compressed.

"Mud" Limit of  24x9-11

Avoid 24x9-11 size for dedicated deep-mud builds. A 9-inch width without aggressive, deep paddles will hydroplane across the top of thick mud rather than cutting down to find a hard base. For the swamp, you need a narrower, "pizza-cutter" style mud tire or a much more aggressive lug.
