Tire Size 295/60r20 vs 285/60r20
The main difference between the two tire sizes is the width. The 295/60R20 tire has a section width of 11.61 inches (295 mm), while the 285/60R20 is narrower at 11.22 inches (285 mm). This 0.39-inch (10 mm) width difference may seem minor, but impacts performance.

Fitment Guide
When replacing tires, the new set should be within 3% of the overall diameter of the original tires to avoid any fitment issues. The 295/60r20 size has a 1.4% larger overall diameter than the 285/60r20.
This minor difference will unlikely cause fitment problems if switching between these sizes. Larger variations beyond 3% may require modifications like a lift kit to accommodate the change in tire size.
Ground Clearance
The 295/60r20 provides 0.47 inches (12mm) more ground clearance than the 285/60r20, thanks to its larger overall diameter. This added clearance is helpful for off-road driving, clearing obstacles, and preventing bottoming out on uneven terrain.
However, the increase in diameter causes a slightly lower speedometer reading on the 295/60r20 compared to the 285/60r20.
Gas Mileage
With a narrower tread and less rotational mass, the 285/60r20 offers marginally better fuel efficiency over the wider and heavier 295/60r20. This can benefit daily driving and long trips.
The 295/60r20’s larger contact patch and weight increase rolling resistance, reducing mileage.
Ride Comfort
The taller sidewall of the 295/60r20 absorbs bumps and impacts more effectively than the 285/60r20. It provides a smoother ride over uneven terrain.
The 285/60r20 offers a firmer, sportier ride that some may prefer on smooth roads. Overall, the 295/60r20 has the comfort edge for rugged conditions.
Aesthetics
Visually, the difference between these sizes is subtle. The 295/60r20’s taller sidewall gives it a slightly stretched look compared to the 285/60r20’s shorter sidewall.
For certain vehicles, the stretched aesthetic of the 295/60r20 can accentuate the wheels and overall style.
Handling & Stability
The 285/60r20’s shorter sidewall enhances handling precision and turn-in response versus the taller 295/60r20.
However, both sizes deliver sharp, stable handling characteristics overall. The 295/60r20’s extra sidewall flex slightly reduces handling quickness.
Noise & Vibration
With its shorter, stiffer sidewall, the 285/60r20 transmits more road noise and vibration into the cabin.
The 295/60r20’s additional sidewall cushioning helps isolate and dampen noise and vibration for a smoother, quieter ride.
Durability & Wear
The narrower 285/60r20 exhibits slightly more even tread wear and marginally longer life than the wider 295/60r20.
The added weight and impacts the larger 295/60r20 endured can increase wear on tires and vehicle components.
Adverse Conditions
Both sizes perform well overall in rain, snow, and off-road use. The 295/60r20’s extra ground clearance gives it a slight advantage in deep snow or over obstacles. The 285/60r20’s shorter sidewall makes it more responsive on slick surfaces.
Speedometer Difference
At an actual vehicle speed of 20 mph, the speedometer reading is slightly lower with 285/60r20 tires compared to 295/60r20 tires. Specifically, the speedometer indicates 19.72 mph with the 285 tires and 20.00 mph with the 295s.
This 0.28 mph difference is attributable to the smaller diameter of the 285 tires. While drivers may notice a minor decrease in indicated speed with the 285s, the discrepancy between these tire sizes is relatively small overall.
Our Observation
Based on the data, both the 295/60R20 and 285/60R20 offer advantages depending on usage. For off-roading or rugged terrain, the taller sidewall and increased ground clearance of the 295 make it the better choice. It absorbs impacts more smoothly and resists damage over obstacles.
For fuel efficiency and responsive handling, the 285 is ideal with its lighter weight and shorter sidewall. On smooth roads, it provides precision cornering and steering feedback.
Overall, the 295’s ruggedness and comfort edge make it the best all-around pick for most drivers and conditions. However, the 285/60R20 is still an excellent option for those prioritizing sporty road handling and maximum mpg. Either way, you get a capable tire for everyday driving.
