Fitment Guide
When replacing tires, the new set should be within 3% of the overall diameter of the original tires to avoid clearance issues.
The 285/75r16 is 6.8% larger than the 265/70r16, exceeding the 3% limit. The larger 285/75r16 may require modifications like a lift kit to prevent rubbing at a complete turn.
Ground Clearance
The larger diameter 285/75r16 provides 1.11 inches more ground clearance than the 265/70r16, an advantage for off-roading over rough terrain.
However, the increased clearance lowers speedometer accuracy. The smaller 265/70r16 has less clearance, increasing the risks of scraping on obstacles but giving a higher speedometer reading.
Gas Mileage
The smaller 265/70r16 has a more minor contact patch and lower rotational mass, conferring better fuel efficiency crucial for daily driving.
The larger 285/75r16 has more rolling resistance and rotational mass, damaging gas mileage.
Ride Comfort
The taller sidewall and diameter of the 285/75r16 absorb road impacts better, providing a smoother ride over uneven terrain.
The shorter 265/70r16 transmits more ride harshness over bumps but may be better for highway comfort.
Aesthetics
The 285/75r16 larger diameter and sidewall give it a more aggressive, “stretched” look suited to trucks and SUVs. The 265/70r16 appears slightly more low-profile, benefiting aerodynamics.
Handling & Stability
The 265/70r16 shorter sidewall enhances responsiveness and handling precision on the pavement. The taller 285/75r16 sidewall flexes more, reducing handling sharpness slightly but aiding stability off-road.
Noise & Vibration
The 265/70r16 stiff sidewall transmits more road noise and vibration into the cabin. The 285/75r16 extra sidewall flex dampens noise and vibration, providing a more isolated ride.
Durability & Wear
The smaller 265/70r16 may exhibit more even treadwear and longer life. The heavier 285/75r16 puts more stress on components, but its larger size can better endure impacts.
Adverse Conditions
The narrower 265/70r16 can cut through the snow for better traction. The wider 285/75r16 is advantageous in deep mud or specific off-road conditions. Both perform well overall.
Speedometer Reading
At an actual speed of 20 mph, the speedometer reads 20 mph with 285/75r16 tires equipped. With 265/70r16 tires, the speedometer reads 18.64 mph at the same actual 20 mph speed, a difference of 1.36 mph.

Our Observation
The 285/75r16 tire size appears better suited for off-road activities, while the 265/70r16 excels on paved roads.
The larger diameter and tread of the 285/75r16 provide more ground clearance, traction in mud, and absorbent ride quality necessary for uneven terrain.
Meanwhile, the 265/70r16 offers superior handling, lower noise, and better fuel efficiency, ideal for regular street driving.
The 285/75r16 is likely the better choice for those who frequently go off-road. But the 265/70r16 is recommended for mostly highway and city driving.
