Tire Size 325/60r20 vs 35×12.50r20

The main difference between 325/60r20 and 35×12.50r20 tire size lies in the section width. While the 325/60r20 has a width of 12.8 inches, the 35×12.50r20 is slightly narrower at 12.52 inches.

This slight difference of 0.28 inches can have implications on various performance factors. Let’s take a closer look at how these two tire sizes compare.

Fitment Guide

The 35×12.50r20 is 2.2% narrower than the 325/60r20. This slight difference is unlikely to cause fitment issues for most vehicles designed for 20-inch wheels.

Both tires should mount without problems on the same wheels. However, always confirm specifications before purchasing replacement tires.

Ground Clearance

The 35×12.50r20 tire has a 0.9% smaller diameter, resulting in 0.33 inches less ground clearance. This slightly lower clearance poses a minor disadvantage for off-roading or traversing rough terrain.

However, the difference is small enough that most drivers would not notice a change in ground clearance between these sizes.

Gas Mileage

With a 2.2% narrower tread and a 0.9% smaller diameter, the 35×12.50r20 tire has marginally less rolling resistance than the 325/60r20.

This can translate into slightly better fuel efficiency, although the difference is minor. Expect nearly identical gas mileage between these sizes during everyday driving.

Ride Comfort

The 35×12.50r20 tire’s 0.17-inch shorter sidewall results in a slightly firmer ride. This stiffer sidewall transmits more road impacts into the cabin than 325/60r20.

However, with only 2.2% difference in aspect ratio, ride comfort is very similar between these two sizes. Most drivers would be hard-pressed to notice a difference.

Aesthetics

Visually, the 35×12.50r20 appears nearly identical to the 325/60r20 on a casual inspection. The 2.2% narrower tread is imperceptible, while the 0.9% smaller diameter causes a subtle reduction in sidewall height. Overall, both sizes suit the aesthetic of most modern trucks, SUVs, and 4x4s.

Handling & Stability

The marginally shorter, stiffer sidewall of the 35×12.50r20 tire subtly improves responsiveness and handling precision.

However, both sizes deliver responsive and stable handling characteristics. Differences would only be noticeable to very attentive drivers.

Noise & Vibration

With its slightly shorter sidewall, the 35×12.50r20 transmits more road noise and vibration marginally into the cabin. However, the difference versus the 325/60r20 is minor. Both tires provide a comfortable, quiet ride for everyday driving.

Durability & Wear

The near-identical sizing suggests durability and treadwear will be very similar between these two tire options.

Expect even wear and comparable lifespan from both, assuming equivalent tread compound and construction quality.

Adverse Conditions

Performance in rain, snow, and off-road conditions is comparable between the 325/60r20 and 35×12.50r20. The 325/60r20’s slightly larger diameter provides a minor advantage in deep snow, while the 35×12.50r20 is fractionally more responsive on wet roads. But both handle adverse conditions equally well.

Speedometer Difference

The 0.9% smaller diameter of the 35×12.50r20 tire causes the speedometer to read 0.69 mph higher than the actual speed. At an actual speed of 20 mph, the speedometer would read 20.69 mph with the 35×12.50r20 tire.

By comparison, the 325/60r20 tire’s larger diameter results in a speedometer reading of 19.81 mph at an actual 20 mph.

What Does 325 60r20 Tire Mean?

325 60r20 is a tire size typically used on SUVs and trucks. This size offers a good balance of traction and stability. The 325 designation means that the tire is 325 millimeters wide.

The 60 refers to the aspect ratio, which is the height of the sidewall. The R in size means that the tire is a radial tire. The 20 is the d rim size in inches, and the letter R indicates the tire’s construction, which is radial.

What Does 35×12 50r20 Tire Mean?

35×12 50r20 is a tire size typically used on lifted trucks and off-road vehicles. This size offers more traction than the 325 60r20 but could be more stable. The first number, 35, means the diameter of this tire is 35 inches.

The second number, 12.5, means the section wide of this tire, which is 12.5 inches. R indicates the tire’s construction, which is radial, and this tire will fit in the 20-inch rim size.

Our Observation
The 325/60r20 offers marginally better ride comfort and ground clearance, while the 35×12.50r20 provides slightly improved handling and fuel efficiency.

The 325/60r20’s extra ground clearance gives it an advantage for off-road use. For a responsive on-road feel, the 35×12.50r20 is ideal. The differences are minor, and both perform well in most conditions.

If choosing between them, we’d recommend the 325/60r20 for its well-rounded capabilities both on and off-road. The extra ground clearance and cushioning are worthwhile benefits.
