BRIDGESTONE Corporation is the world’s largest tire and rubber company, with more than 80 years of experience and insistence on quality in aircraft tire manufacturing. The company supplies new and retread tires (*) to airlines and wheelshops worlwide remaining one of the most trusted brands in the aviation industry.
BRIDGESTONE® range of aircraft tires includes Bias, Radial and Revolutionarily Reinforced Radial Tires (RRR). They work under extremely severe conditions, carrying the weight of an aircraft up to 569 metric tons while accelerating up to 245 mph at takeoff, in addition to enduring varied environmental stress when in flight and taxiing.
BRIDGESTONE® Bias tires feature enhanced tire durability, greater overload durability, reduced weight, new cord and performance improvements due to the integration of Tension Control Optimization (TCOT) and Aircraft Tire Tension Control Optimization (ACOT) Theory principles.
BRIDGESTONE® Radial tires feature lighter design, reduced rolling resistance, rigged belt design, added strength to belt and carcass plies and increased number of landings.
BRIDGESTONE® Revolutionarily Reinforced Radial Tires (RRR) feature superior safety, higher cut resistance, more casing durability after received Foreign Object Damage (F.O.D.), economy, less weight and more landing cycles (improved tire wear). They have been selected by Airbus and Boeing as OE tires for their respective aircraft.
(*) Retread tires have undergone a remanufacturing process to replace the worn tread on used tires with new tread to help extend the life of the tire. The number of times the tread has been replaced in the tire casing is indicated by a number just after the letter "R" in the product reference number (SKU), namely R1, R2, R3 and so on.
RRR Tire Performance
Superior Safety
Not every cut leads to immediate or even eventual tire failure. However, there are two basic "worst case scenario" when an aircraft tire hits a foreign object.
The tire bursts if the foreign object penetrates through the tread into or through the casing.
The tire tread peels off if the cut damage is limited to the tread area.
To minimize the occurrence of these two types of tire destruction, BRIDGESTONE focused on:
- enhancing cut resistance by lowering tension of the tire tread
- separating the inner and outer belt functions, allowing the inner belt to bear tension in order to reduce tension on the outer belt, thus enabling the outer belt to function as a cut protector against external damage.
Economy
BRIDGESTONE's RRR tire construction technology offers two additional benefits:
Less Weight
A reduction in belt weight as a result of a more optimum construction and shape in addition to the application of superior materials.
A reduction in carcass weight as a result of rigid belt construction which enables to reduce carcass tension, allowing for a reduction in materials.
More Landing Cycles (Improved Tire Wear)
Improved wear resistance due to a reduction in tension on the tread surface.
Less weight (i.e. reduced tire inertia) benefits in reduced tire slippage at landing.
