Tire Size 285/75r16 vs 33×12.5r16

The main difference between 285/75r16 and 33×12.5r16 tires lies in section width. The 285/75r16 tire has a section width of 11.22 inches (285mm), while the 33×12.5r16 tire has a wider 12.52 inch (318mm) section width, a difference of 1.3 inches (33mm).

285/75r16 vs 33×12.5r16

This comparison table will provide you with a quick understanding of the differences.

Fitment Guide

Replacement tires should be within 3% of the original tire’s diameter to avoid clearance issues or speedometer errors.

The overall diameter of 33×12.5r16 tires is just 0.6% larger than 285/75r16. This minor size difference means 33×12.5r16 can directly replace 285/75r16 tires without modifications.

Both sizes should fit the same wheels and provide comparable speedometer accuracy.

Ground Clearance

With a diameter of 33.03 inches, 33×12.5r16 tires offer 0.2 inches more ground clearance than 285/75r16 tires, which have a diameter of 32.83 inches.

This slightly higher clearance benefits off-road driving, enabling vehicles to traverse rough terrain without scraping.

Gas Mileage

The wider 33×12.5r16 tires have 11.6% more tread contacting the road, increasing rolling resistance slightly compared to 285/75r16.

This typically translates to marginally reduced fuel efficiency. However, the difference is generally modest between these sizes. Overall vehicle gearing and other factors also impact mileage.

Ride Comfort

Both tires provide a comfortable ride quality. The nearly identical sidewall height means suspension compression is similar over bumps and uneven surfaces.

The 285/75r16 tires may have a subtle edge in ride smoothness on the highway due to the narrower tread. But both absorb impacts well and avoid excessive harshness.


Visually, the 33×12.5r16 appears somewhat wider and more aggressive due to the 1.3-inch extra section width.

This aesthetic suits trucks and larger SUVs well. However, the difference is fairly subtle, and both sizes have an attractive, proportional look.

Handling & Stability

The 285/75r16 narrower tread provides a handling advantage on the pavement with quicker steering response and better cornering grip.

However, the 33×12.5r16 wider footprint delivers confident stability, especially for larger vehicles. Both handle well, but the narrower tire is optimal for responsive performance.

Noise & Vibration

With nearly identical diameters and sidewall heights, these tires demonstrate comparable interior noise and vibration levels.

Both absorb imperfections effectively and avoid excessive road noise. The 33×12.5r16 wider tread produces slightly more noise at highway speeds, but the differences are modest.

Durability & Wear

The 33×12.5r16 greater tread width distributes wear over more rubber, resisting irregular wear patterns. However, the added weight could marginally accelerate component wear.

In most cases, both tires deliver long tread life and even wear. Proper wheel alignment and rotation help optimize durability.

Adverse Conditions

Performance in rain, snow, and off-road conditions is comparable between these sizes. The minimal difference in dimensions results in similar levels of traction.

Both tread patterns also play a key role in performance. Overall, both sizes handle adverse conditions well.

Speedometer Difference

At an actual speed of 20 mph, the speedometer reads 0.12 mph higher with 33×12.5r16 tires compared to 285/75r16 tires due to the slightly larger overall diameter.

This minor variation has a negligible impact on driving. But, it demonstrates the importance of size compatibility with vehicle electronics.

What Does 285/75r16 Mean?

The 285/75r16 size is famous for many truck and SUV owners. This size tire is typically used on larger vehicles that need more ground clearance.

The “285” refers to the width of the tire in millimeters, while the “75” refers to the sidewall height.

The “r” in this size designation means that the tire is a radial tire. Finally, the “16” indicates that the wheel diameter is 16 inches.

What Does 33×12 5r16 Mean?

The 33×12.50r16 size is another popular choice for many truck and SUV owners. The “33” refers to the tire’s width in inches, while the “12.50” refers to the sidewall height.

The “r” in this size designation means that the tire is a radial tire. Finally, the “16” indicates that the wheel diameter is 16 inches.

Our Observation
Based on the comparisons, the 285/75r16 is arguably the better all-around tire for most drivers. Its slightly narrower size promotes fuel efficiency and handling, which benefits everyday driving.

The 33×12.5r16 offers marginally more off-road clearance and capability but is somewhat low in street performance. For vehicles routinely facing rugged terrain and obstacles, the 33×12.5r16 is an excellent choice.

However, for most truck and SUV owners primarily do street driving, we recommend the more well-rounded 285/75r16 tire. Its blend of responsiveness and comfort make it the best bet for mixed on and off-road use.
