Tyre Selection Guide

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 1.5 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.

Winter tyres have "Platform Indicators" in the grooves, marked with an arrow on the sidewall, which indicates their location. Winter 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. Stones, 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.

USER 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.

* Do not mix different tyre size designations or constructions on the same axle. Always use the tyres for their intended service purpose. * Some vehicles require specialized tyre fitment. Please consult your YOKOHAMA distributor for details. * The RY637 should, to achieve maximum performance, be used on the steer axle in long distance smooth road operation.* For maximum performance, the TY607 should be used on regional transport. * The MY507A WB can also be used on the steer axle in on & off short distance operation. * Under normal highway conditions, the steer tyres above can also be used on the drive axles.* The availability of products shown in this table may vary from country to country. * Please consult your YOKOHAMA distributor for local availability.

Moisture in a tyre can damage the casing. Stock tyres in a dry area. Dry interior before mounting. Inflate with dry air.

TECHNOLOGIES TO GIVE YOU THE ADVANTAGE!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.

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.

Tread

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.

Belt Edge Cushion

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.

Inner Liner

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.

Bead Filler

Thin, highly adhesive assembly compounds are used in YOKOHAMA’s tyre casing and belts to prevent separation of the steel cords.

Belts and Casing

YOKOHAMA’s undertread compounds have low heat-generating characteristics, which prevent tread separation.

Undertread

YOKOHAMA’s special sidewall compounds are selected for high flexibility, excellent durability and high resistance to fatigue and weather cracking.

Sidewall

YOKOHAMA’s rim cushion compound is highly resistant to the heat transmitted by the rim.

YOKOHAMA: MAXIMIZE YOUR PERFORMANCERecommendations to ensure the top performance of your YOKOHAMA tyres.

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*.

CORRECT INFLATIONmaintains even road contact for maximised performance.

UNDERINFLATIONcauses abnormal tyre deflection,which builds up excessive heat, and risk of failure. It also causes excessive wear on the shoulder.

OVERINFLATIONincreases the risk of

impact breaks and other road hazard damage.

It also causes excessive wear in the centre.

Inflation Pressure

* Check YOKOHAMA's recommendations for inflation pressures at the back of this booklet.

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

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.

Every new YOKOHAMA truck tyre product is designed and constructed for better retreadability.

In addition, YOKOHAMA casings are backed up by the special "CASING WARRANTY" available.

Please consult your YOKOHAMA distributor for details.

Retreading

Regrooving must be undertaken when only between 2 to 3 mm of the original tread pattern remains,

in accordance with YOKOHAMA's recommendations in this booklet.

Regrooving

Winter 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 SY397 M+S) for each winter season.

Tyre Selection Guide

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 1.5 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.

Winter tyres have "Platform Indicators" in the grooves, marked with an arrow on the sidewall, which indicates their location. Winter 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. Stones, 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.

USER 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.

* Do not mix different tyre size designations or constructions on the same axle. Always use the tyres for their intended service purpose. * Some vehicles require specialized tyre fitment. Please consult your YOKOHAMA distributor for details. * The RY637 should, to achieve maximum performance, be used on the steer axle in long distance smooth road operation.* For maximum performance, the TY607 should be used on regional transport. * The MY507A WB can also be used on the steer axle in on & off short distance operation. * Under normal highway conditions, the steer tyres above can also be used on the drive axles.* The availability of products shown in this table may vary from country to country. * Please consult your YOKOHAMA distributor for local availability.

Moisture in a tyre can damage the casing. Stock tyres in a dry area. Dry interior before mounting. Inflate with dry air.
