Fitment Guide
The 33×12.50r20 tire is about 6% smaller in overall diameter compared to the 295/65r20. This exceeds the 3% diameter difference limit for direct replacement tires.
The 33×12.50r20 would likely require lifting the vehicle to prevent rubbing or other fitment issues.
Ground Clearance
With a diameter of 35.1 inches, the 295/65r20 provides 2.08 inches more ground clearance than the 33×12.50r20, which has a diameter of 33.02 inches.
This added clearance is helpful for off-road driving, helping prevent damage from obstacles. However, the larger 295/65r20 diameter causes a lower speedometer reading than the 33×12.50r20.
Gas Mileage
The 295/65r20 larger contact patch and heavier weight results in more rolling resistance, potentially reducing fuel efficiency compared to the 33×12.50r20.
With less rotational mass, the 33×12.50r20 confers better gas mileage, an advantage for daily drivers.
Ride Comfort
The 295/65r20 taller sidewall cushioning absorbs bumps and impacts, providing a smoother ride over uneven terrain.
Meanwhile, the 33×12.50r20 offers a firmer, more responsive ride that can jitter over rough roads. On smooth highways, the 33×12.50r20 likely provides a more comfortable experience.
Aesthetics
Visually, the 295/65r20 taller sidewall suits the aesthetic of trucks and SUVs well. The 33×12.50r20 shorter sidewall has a sportier, lower-profile appearance that some prefer.
Overall, the aesthetic difference between the sizes is minor and subjective.
Handling & Stability
The 33×12.50r20 shorter sidewall enables quicker steering response and sharper handling on paved roads. In contrast, the taller 295/65r20 sidewall has more flex, reducing handling precision but increasing stability off-road.
Both offer responsive handling, but the 33×12.50r20 has a slight handling advantage on the pavement.
Noise & Vibration
With its shorter, stiffer sidewall, the 33×12.50r20 transmits more road noise and vibration into the cabin than the 295/65r20. The 295/65r20 additional sidewall flex better dampens noise and vibrations for a more isolated ride quality.
Durability & Wear
The potentially longer tread life and even wear characteristics of the 33×12.50r20 make it the more durable tire.
The larger 295/65r20 encounters more impacts and stress that can reduce tread life and add rotational mass that increases drivetrain wear.
Adverse Conditions
In snow and ice, the narrower 33×12.50r20 can cut through to the pavement more effectively.
The wider 295/65r20 struggles for grip on snow but provides better traction in mud or off-road conditions. Overall traction differences are minor between the two.
Speedometer Difference
Due to its larger diameter, the 295/65r20 causes a lower speedometer reading than the 33×12.50r20.
At an actual speed of 20 mph, the speedometer reads 18.82 mph with the 295/65r20 but 20 mph with the 33×12.50r20, a difference of 1.18 mph.
What Tire Size Is Equivalent To 33×12.5×20?
The tire size equivalent to 33×12.5×20 is 325/50r20. This size has a diameter of 32.8 inches, a width of 12.8 inches, and fits a 20-inch wheel.
Another close equivalent is 305/55r20, which has a diameter of 33.2 inches and a width of 12 inches. These sizes are commonly used on trucks, SUVs, and other larger vehicles.
