Ground Clearance

The 35×12.50R20 provides 0.95 inches (24mm) more ground clearance due to its larger diameter.

This improves off-road capability and helps avoid scrapes over obstacles. However, the larger size causes a 2.7% lower speedometer reading.

Gas Mileage

The wider 35×12.50R20 has more rolling resistance, reducing gas mileage compared to the 275/65R20. The 35’s extra 1.69 inches of width increases friction and drag. Their heavier weight also increases fuel consumption.

Ride Comfort

While the 275/65R20 offers a smooth highway ride, the 35×12.50R20’s additional sidewall height absorbs bumps better. Its 7.51-inch sidewall cushions impact off-road for a more comfortable ride over rugged terrain.


Subjectively, the 35×12.50R20 looks more aggressive than the 275/65R20. Its bulging width and sidewall evoke a rugged, off-road style. However, the 275/65R20 maintains a sleeker on-road aesthetic.

Handling & Stability

The 275/65R20 provides quicker steering response and handling due to a shorter sidewall and smaller contact patch. But the 35×12.50R20 offers stability through wider traction and heavier weight.

Noise & Vibration

The 35×12.50R20 runs quieter as its flexible sidewall absorbs road noise. But its aggressive tread likely generates louder noise patterns. The 275/65R20 transmits more vibration through its stiffer sidewall.

Durability & Wear

The narrower 275/65R20 exhibits even treadwear and potentially longer life. The heavier 35×12.50R20 endures more impact, but its width causes uneven wear. It also stresses suspension components.

Adverse Conditions

The narrow 275/65R20 cuts through the snow for better winter traction. But the 35×12.50R20’s size provides superior traction in mud, rocks, and sand. Its extra ground clearance also helps in adverse conditions.
