2 TECHNOLOGIE TO GIVE YOU THE YOKOHAMA is constantly striving to create the best solutions for each application. YOKOHAMA s commitment to you and to the environment ensures the most cost-effective high-performance tyres. YOKOHAMA s Concept Fleets today need more miles, greater retreadability, longer even-wear and less maintenance costs per kilometre from their tyres. Given the extreme demands of today s transport industry, continuous innovation in tyre technology is essential. YOKOHAMA s technologies help you get the most out of your tyre investments. Tyre Construction Tread Compounds used in the tread depend on the tyre s specific application needs. YOKOHAMA has chosen various compounding strategies to minimize treadwear rate, and maximize traction, fuel efficiency, and resistance to fatigue, chipping and scaling. Belt Edge Cushion YOKOHAMA tyres feature a belt edge cushion to help prevent separation of the belt edges, and therefore the tread, caused by the scissoring effect of the belts. Inner Liner YOKOHAMA s inner liner is specially designed to minimize air seepage into adjacent areas of the tyre. The quality of the inner liner is critical to prevent air from penetrating into the casing. YOKOHAMA s special inner liner compound ensures a significantly longer casing life. Bead Filler Two or more different compounds are used in YOKOHAMA s bead filler (apex rubber) to stiffen the bead for steering response and to control the flexibility of other parts of the tyre. Belts and Casing Thin, highly adhesive assembly compounds are used in YOKOHAMA s tyre casing and belts to prevent separation of the steel cords. Undertread YOKOHAMA s undertread compounds have low heat-generating characteristics, which prevent tread separation. idewall YOKOHAMA s special sidewall compounds are selected for high flexibility, excellent durability and high resistance to fatigue and weather cracking. Rim Cushion YOKOHAMA s rim cushion compound is highly resistant to the heat transmitted by the rim. Individual Technologies Groove IC Rib ipe Rib C* Groove To improve the shoulder "tep-own ear".

4 INTROUCING YOKOHAMA TECHN A new era in the development of truck and bus tyres. Lower Temperature / Higher Torque Mixing Method A new compound mixing method has increased the durability of tyres. Rubber / Reinforcing Agent and other Traditional Mixing Method Multi-tep Mixing The traditional multi-step mixing process mixes and kneads the rubber simultaneously. Mixer Mixer Mixer Mixer The long periods of mixing result in high temperatures, which tend to cause deterioration in the quality of the rubber. Compound Compound Compound Compound Rubber / Reinforcing Agent and other NE Lower Temperature / Higher Torque Mixing Method Mixer Compound Compound Roll One tep Mixing & Roll Mixing The new method performs the kneading of the rubber on rollers after the rubber has been mixed. This process results in lower temperatures. It thus minimizes the splitting of the rubber s long polymer chains and promotes a more even distribution of the carbon black particles, which are used as a reinforcing agent. Microscopic imagery reveals the improvement in rubber composition that results from the new Lower Temperature & Higher Torque Mixing Method Rubber tructure Model Traditional Mixing Method New Lower Temperature Higher Torque Mixing Method Traditional Mixing Method ioxide New Lower Temperature Higher Torque Mixing Method Carbon Carbon Rubber (polymer) Rubber (polymer) oft and less flexible rubber Tough and flexible rubber The distribution of carbon particles is more even in rubber produced with the new Lower Temperature / Higher Torque Mixing Method process than in traditionally processed rubber. The new Lower Temperature & Higher Torque Mixing Method significantly reduces dioxide obstacles and disperses carbon in rubber evenly.

6 YOKOHAMA: MAXIMIZE YOUR PER Recommendations to ensure the top performance of your YOKOHAMA tyres. Inflation Pressure Truck tyres for commercial vehicles must be inflated to a pressure relevant to the load, speed and condition of use to produce maximum performance in all aspects such as even wear (long mileage), traction and handling stability (riding comfort) in addition to safety issues*. * Check YOKOHAMA's recommendations for inflation pressures at the back of this booklet. CORRECT INFLATION maintains even road contact for maximised performance. UNERINFLATION causes abnormal tyre deflection, which builds up excessive heat, and risk of failure. It also causes excessive wear on the shoulder. OVERINFLATION increases the risk of impact breaks and other road hazard damage. It also causes excessive wear in the centre. Tyre pressures should be checked on cold tyres at least every two weeks, using a calibrated pressure gauge. Tyres with lower profiles must be checked strictly due to 8.50bar Truck & Bus Tyres 5psi Truck & Bus Tyres their less visible sidewall deflection. YOKOHAMA provides "inflation pressure stickers" with several different values to help customers maintain proper pressures. Please contact your YOKOHAMA distributor for details. Retreading Every new YOKOHAMA truck tyre product is designed and constructed for better retreadability. In addition, YOKOHAMA casings are backed up by the special "CAING ARRANTY" available. Please consult your YOKOHAMA distributor for details. Regrooving Regrooving must be undertaken when only between to mm of the original tread pattern remains, in accordance with YOKOHAMA's recommendations in this booklet. inter Tyre Application inter tyres are normally designed with a fine, deep and wide tread to ensure traction on snowy/icy roads. These products are not suited to hot and rough road surfaces. YOKOHAMA strongly recommends fitment of brand-new winter tyres (especially in the case of Y97 M+) for each winter season. 6

UER INFORMATION: Only specially trained personnel should mount tyres. Failure to comply with these tyre demounting/mounting safety precautions can cause the bead to break and the assembly to burst with sufficient force to cause serious injury or death. Always deflate tyre completely before removing lock or side rings. Never use wheels of different manufacturers or different sizes. Never mount tyres on wheels which are damaged or not smooth and clean. Always clean and inspect wheel. Lubricate beads [and rim flanges for tubeless types], tube and rim side of flap with an approved rubber lubricant. Always be sure that wheel components are properly seated before inflating. Always use an extension hose with gauge and clip-on chuck. Never inflate beyond.5 bar prior to placing tyre/wheel assembly in a safety cage. Always use a safety cage or other restraining device when inflating the tyre to seat the beads and/or inflating the tyre to normal operating inflation pressure. Never stand, lean or reach over the assembly during inflation. After beads are fully seated, adjust to vehicle manufacturer's recommended inflation pressure. Never mount radials on the same axle with bias tyres. Follow vehicle manufacturer s recommendations. Tyres must be removed when remaining tread depth reaches regulated minimum tread pattern in a country. inter tyres have "Platform Indicators" in the grooves, marked with an arrow on the sidewall, which indicates their location. inter tyres can no longer be used as winter tyres after the "Platform Indicators" have appeared on the tread surface. This occurs when the original tread depth has approximately 50% wear. tones, gravel and other foreign objects stuck in the tyre treads may damage the tyre. Remove foreign objects from the treads. Objects in the road such as potholes, glass, metal, rocks, wood debris, kerbstones and others that could damage a tyre should be a safely avoided. To preserve traffic safety and tyre life, YOKOHAMA recommends driving safely and avoiding hard acceleration, braking or cornering in unnecessary situations. If you feel the vehicle is unstable or feel any unusual noises or vibrations, stop your vehicle in a safe place and inspect your tyres. Even if no visible defects are found, drive slowly and ask your tyre dealer to inspect your tyres as soon as possible. Never use a tyre under the following conditions and replace a tyre immediately: If the tread has worn to the tread wear indicator. If breaks in the fabric appear. If cords or wires are exposed. Moisture in a tyre can damage the casing. tock tyres in a dry area. ry interior before mounting. Inflate with dry air. ITRIBUTE BY: 0 by YOKOHAMA Europe GmbH. Printed in Germany CE9 79 ABC 0
