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 315/75r16 tires is 5.4% larger than 285/75r16.
So 285/75r16 tires could potentially replace 315/75r16 tires, but not vice versa. If you interchange, the 315/75r16 may require modifications like a lift kit to prevent rubbing at the complete turn.
Ground Clearance
The larger 315/75r16 tire size provides 0.89 inches (22.5mm) more ground clearance than the 285/75r16, which is beneficial for off-roading.
However, the increased diameter of 315/75r16 tires causes a lower speedometer reading compared to 285/75r16 tires.
Gas Mileage
The 315/75r16 tires are heavier with more rolling resistance, which could lead to slightly worse fuel efficiency compared to the 285/75r16.
The more minor contact patch and lower rotational mass of 285/75r16 tires confer better gas mileage.
Ride Comfort
The taller sidewall and larger overall diameter of 315/75r16 tires provide a smoother ride over uneven terrain.
The flexible sidewalls absorb impacts better than the shorter 285/75r16 sidewalls. However, the 285/75r16 may feel more comfortable on smooth roads.
Aesthetics
Visually, the wider 315/75r16 tires fill out the wheel wells more. Some drivers prefer the aggressive, “stretched” look of a wider tire.
However, others find the more proportional look of a narrower tire more appealing. It comes down to personal taste.
Handling & Stability
The 285/75r16 tire’s shorter sidewall enables crisper steering response and handling precision.
But the 315/75r16’s additional traction from the wider tread helps maintain stability in corners. Both offer responsive handling, but the 285/75r16 has a slight edge.
Noise & Vibration
The 285/75r16’s shorter sidewall transmits more road noise and vibration into the cabin.
The taller 315/75r16 sidewall dampens vibrations better for a smoother, quieter ride. However, aggressive tread patterns on either size increase noise.
Durability & Wear
The narrower 285/75r16 tire exhibits more even treadwear across its width, leading to potentially longer life.
The heavier 315/75r16 tire causes more strain on suspension components, possibly decreasing durability. But both sizes are quite durable overall.
Adverse Conditions
Winter traction is a wash between the two. The narrower 285/75r16 cuts through snow better, but the wider 315/75r16 offers more traction.
For off-road and mud, the wider 315/75r16 provides an advantage with its additional grip.
Speedometer Reading
Due to the larger overall diameter, the speedometer reads 1.08 mph higher with 315/75r16 tires than with 285/75r16 tires at the same true speed.
For example, at an actual speed of 20 mph, the speedometer would read 21.08 mph with 315/75r16 tires equipped.
