Tire Types and Tread Patterns
Aircraft tires are classified by size, structure, ply rating, tread pattern, as well as by inflation pressure and tire profile. Bridgestone currently manufactures Type III, VII, Radial, Metric and Three Part Type tires.
Radial
Radial tires are designed with the specific targets of lightweight construction and high overload capabilities. Low heat generation enhances the tire's performance, and the tire is notable for its excellent landing performance.

Three Part Type
All newly created sizes are classified as Three Part Type. This group is designed to meet specific operational requirements such as high speed running or overload operations.

Metric Type
Metric Sizes are the same as Three Part Type sizes except that dimensions are expressed in millimeters.

Type VII
This type of tire is used on the jet and turboprop aircraft of today. It is chara-cterized by its conventional sectional shape and by its high load capabilities.
Type III
The section width of these tires is large in relation to the bead diameter, so that improved cushioning and floatation are obtained at low pressure.

Center Rib Tread
All Bridgestone radial and newer bias tires utilize the center rib pattern (CB) for aircraft tires. This pattern consists of ribs in a circumferential direction and is characterized by excellent wear resistance, improved braking, and added directional stability.

Rib Deflector Tread
This pattern (CD, RD) was developed for rear-engined jet aircraft. A flange is provided on the sidewall to deflect runway water away from the engines.

CD: Canter rib with deflector
RD: Center groove with deflector
Radial CB: Center rib CD: Center rib with deflector
