Tread Design

Types of Tread Patterns


The tread pattern is like the ‘footprint’ of a tire, and each one is intended for a specific application. A proper tread design improves traction and handling, and also affects ride comfort, noise level and fuel efficiency.

The tread pattern, combined with specially-formulated rubber compounds gives each tire its specific performance characteristics. While tread compounds are formulated to their expected use, we’re always researching new and innovative ways to improve both tire performance and fuel efficiency.


Block Type
Block type tread patterns are composed of independent blocks for:
  • Outstanding braking force and traction
  • Good traction on snow or in muddy terrain
Block type

Rib Type
Rib type patterns feature tread and grooves that follow the tire’s circumference for:
  • Low rolling resistance
  • Comfortable ride
  • Good steering
  • Relatively low noise generation

Rib-Block Type
Rib-block type patterns combine block type tread in the center with a shoulder rib design for:
  • Low rolling resistance
  • Comfortable ride
  • Relatively low noise generation
  • Good traction on snow or muddy terrain

Lug Type
Lug type patterns feature grooves that are cut across the tread for:
  • High braking force
  • Excellent traction on unpaved surfaces

Tread Design and Wet Road Conditions


A tire’s tread design includes grooves which create voids within the tread face for better water channeling on wet road surfaces.


Circumferential Grooves
The most efficient means of channeling water is circumferentially around the tire — the shortest distance between the front and rear edge of the contact patch.
circumferential grooves
Lateral Grooves
Lateral grooves help break up the wedge of water that forms at higher speeds to reduce the chance of hydroplaning and increase the tire's contact with the road.

Tread Design Features


Every detail of our tires’ tread is designed and engineered to deliver the perfect balance of performance, efficiency, and durability.

Stress Wear Control Groove
Stress wear control grooves reduce contact pressure at the tread edge, providing increased resistance to shoulder step for longer wear.

Stress Equalizer Ribs
Stress equalizer ribs ensure even contact pressure along the shoulders to combat step down wear.

Closed Shoulder Drive
A closed shoulder drive provides even wear, which translates to more road miles.


Closed Shoulder Drive

Open Shoulder Drive
An open shoulder drive features sturdy shoulder blocks that are precisely spaced for outstanding traction and to minimize retention of foreign objects.

Void Volume
A low void ratio means more rubber is in contact with the road. A high void ratio increases the ability to drain water. Whether a tire has a high or low void ratio depends on the tire's intended use.

Microsipes
Microsipes optimize rib contact pressure to combat uneven wear and improve wet handling and braking.

Groove Protectors
Groove protectors boost durability and retreadability by preventing stones from traveling to the bottom of the grooves, reducing damage to the casing by 25%.

Groove Amplitude
Using "zigzag" grooves gives a tire more driving and braking traction, especially on soft surfaces.

Checking Tread Depth


Checking your tires' tread depth allows you to monitor wear and estimate the total miles you should expect out of each tire based on your operation.
Here’s a quick look at how to properly check your tires’ tread depth and what the measurements mean for your business:
