Fitment Guide

The 33×12.50R22 is 2.9% larger in overall diameter than the 285/45R22. Replacement tires should be within 3% of the original tire’s diameter to avoid clearance issues or speedometer inaccuracies.

Larger tires, like the 33×12.50R22, may require modifications like a leveling kit or lift kit to fit vehicles designed for smaller tires properly.

Ground Clearance

With a diameter of 33.02 inches, the 33×12.50R22 tire size provides 0.92 inches more ground clearance than the 285/45R22 size at 32.1 inches.

This added clearance is helpful for off-road driving, helping prevent scrapes over rocks or obstacles. However, the larger diameter also causes a lower speedometer reading than the smaller 285/45R22.

Gas Mileage

The 285/45R22’s more minor contact patch and lower rotational mass provide better fuel efficiency than the larger, heavier 33×12.50R22.

The wider footprint and extra weight of the 33×12.50R22 increase rolling resistance, reducing mileage.

Ride Comfort

While the 285/45R22 offers a smooth highway ride, the 33×12.50R22’s additional sidewall height absorbs impacts better, providing a more comfortable ride over very uneven terrain. Its larger air volume also dampens noise and vibration.


Visually, the 33×12.50R22 has a taller, more stretched look owing to its larger sidewall, suiting trucks and SUVs. The 285/45R22 looks slightly more low-profile, enhancing the aerodynamics of sports cars.

Handling & Stability

The shorter sidewall of the 285/45R22 provides sharper handling and quicker response on pavement. The taller 33×12.50R22 sidewall flexes more, reducing handling precision but increasing stability off-road.

Noise & Vibration

With its shorter, stiffer sidewall, the 285/45R22 transmits more road noise and vibration into the cabin. The 33×12.50R22’s additional sidewall flex better dampens noise and vibration.

Durability & Wear

The smaller 285/45R22 exhibits more even treadwear and potentially longer life. The larger 33×12.50R22 endures more impacts, but its weight strains components, potentially accelerating wear.

Adverse Conditions

In snow, the narrower 285/45R22 cuts through to the pavement better. But in mud, the wider 33×12.50R22 provides superior traction. The 33×12.50R22’s extra ground clearance also helps in light off-roading.

Speedometer Reading

At an actual speed of 20 mph, the 285/45R22 equipped vehicle’s speedometer reads 20 mph. But with 33×12.50R22 tires, the speedometer reads 20.57 mph due to the larger diameter. This 0.57 mph difference is typical between these sizes.
