Fitment Guide
The 255/85r16 has an overall diameter of 0.7% smaller than the 285/75r16. Replacement tires should be within 3% of the original size’s diameter to avoid issues with speedometer accuracy or rubbing against wheel wells.
The 255/85r16 can likely replace a wider range of original sizes. The 285/75r16 may require lifting or leveling kits on some vehicles for proper fitment without rubbing.
Ground Clearance
With a 0.7% larger diameter, the 285/75r16 offers increased ground clearance compared to the 255/85r16. This can help prevent scrapes and damage from obstacles, improving off-road capability.
But it also causes a slightly lower speedometer reading at a given speed. The 255/85r16 has less clearance, increasing the risks of scrapes but giving a higher speedometer readout.
Gas Mileage
The 285/75r16’s larger size adds more weight and rolling resistance, likely decreasing gas mileage compared to the lighter 255/85r16.
Less rubber on the road and lower rotational mass help the 255/85r16 provide better fuel efficiency.
Ride Comfort
The 255/85r16 offers a smoother ride on paved roads with its shorter sidewalls. But the 285/75r16’s taller sidewalls and larger air chamber absorb bumps better, providing superior comfort on uneven terrain. Overall, ride quality is a tradeoff between on and off-road scenarios.
Aesthetics
The 285/75r16 has a taller, more aggressive look, which suits trucks and larger SUVs. The 255/85r16 maintains a lower, car-like profile that blends in across more vehicle types. It may also aid aerodynamic efficiency better.
Handling & Stability
The shorter sidewall and smaller contact patch of the 255/85r16 improve handling precision and sensitivity on the pavement.
But the 285/75r16’s larger footprint and sidewall flex lend it more stability and traction off-road. Handling reflects the intended use of each size.
Noise & Vibration
Expect more road noise and vibration transmission from the stiffer 255/85r16. But the larger 285/75r16 generates more noise, especially with aggressive treads.
The 285/75r16 better dampens vibrations through the sidewall. Overall noise levels are comparable.
Durability & Wear
The lighter 255/85r16 should exhibit more even tread wear over time. The heavier 285/75r16 endures more impact, but its weight could also wear driveline components faster.
Even wear favors the 255/85r16, while impact endurance leans towards the 285/75r16.
Adverse Conditions
In snow and ice, the narrower 255/85r16 may cut through to pavement better, improving grip. The wider 285/75r16 provides more traction in deep mud or rough terrain. Performance in adverse conditions depends on the specific environment.
Speedometer Reading
The 255/85r16 will read 0.7% higher on the speedometer at a given speed than the 285/75r16. At 20 mph true speed, the speedometer reads 20.7 mph for the 255/85r16 and 19.86 mph for the 285/75r16, a difference of 0.84 mph.
