2 Thickness Thickness of water of water film um film um A breakthrough in winter tire technology! Before designing the latest generation of winter tires, Yokohama engineers set out to solve a fundamental problem what causes a tire 2.50 to slip on ice? They discovered the most formidable 0 challenge in winter driving is a thin film of water on icy surfaces that causes micro-hydroplaning. But the real breakthrough came when they found that a film as thin as ten one-thousandths of a millimetre is all it takes to completely lose control. And that the danger is at its worst as the temperature rises to the freezing mark. Armed with this information, they created Yokohama s most advanced winter tires yet tires that will set a new standard against which all others will be compared. For superb traction and handling on snow and ice even in the traction danger zone of -6 to 0 Celsius choose Yokohama winter radials. And join the evolution of traction on ice.

3 Yokohama s rally drivers win North American Rally Championships on IceGuard IG20 tires. THE choice of leading Canadian Rally Racers. Yokohama is constantly pushing the envelope in the development of advanced winter tire technologies, and our new generation of products takes this effort to a whole new level. Once an achievement like this has been made, there s only one place to really put it to the test in the Canadian winter rally racing circuit. The treacherous ice and snow conditions faced by professional drivers can only be overcome by the most advanced tires available, and the IG20 outperformed to rave reviews by the drivers themselves. In 1984 we started turning heads by winning the Canadian Rally Championship. Since then, we have participated in numerous Canadian auto sport events, always competitive, and often winners. In rally competition, we have been supporting sponsors of the Canadian Rally Championship for many years, and in 2010, we are sponsoring 3 teams: one led by current Canadian Rally Champion Patrick Richard, the others by Antoine L Estage and Andrew Comrie-Picard. In auto sport competition, we re committed to showing the way to excellence, as we do with our winter radials, all the way down the road. See the IG20 in action at Yokohama.ca

4 IN THE FUTURE, ALL WINTER TIRES WILL BE JUDGED AGAINST THIS ONE. Building on the exceptional success of the Ice Guard IG10, the Ice Guard IG20 represents a great leap forward in winter traction technology. Designed to cut through the watery film on ice that causes micro-hydroplaning, each Yokohama IG20 features hundreds of millions of absorptive carbon flakes and billions of resin-coated shelled microbubbles. The tread design has been refined to offer better grip during acceleration, cornering and braking in the worst winter weather, including in slush and snow and on ice. The IG20 has also been optimized to provide long-lasting wear and low road noise. But don t take our word for how well it performs when winter is at its worst you be the judge! 1.

Two compound elements combine to eliminate the thin film of water that causes slipping: Absorptive carbon flakes use capillary action to draw water away from the surface. Shelled microbubbles absorb any remaining water & improve contact with the ice & snow surface. As the tire rotates, the water is expelled, prepared for its next contact with the road surface. The silica with Zeruma agent compound enhances tire tread flexibility in very cold conditions, enabling it to grip the road. 3-D pyramid-shaped sipes interlock to maintain strong tread blocks, improving block stiffness during acceleration, braking & cornering. Multiple edges offer better grip & control. Groove-in-groove design along the edges of the tread blocks controls uneven wear by dispersing stress & heat. Micro-diagonal grooves on the initial tread surface provide immediate performance on slippery surfaces. 4 wide straight grooves accelerate water expulsion & improve directional stability for improved handling. Extended centre blocks reduce noise & improve braking & handling stability. Slush grooves on the outside blocks force slush & snow away from the centre of the tread. WINTER RADIAL

6 MAINTENANCE AND SAFETY INFORMATION Yokohama tires are sophisticated in design, and like any high-quality product, they require owner maintenance to perform at their best. Operational damage such as incorrect inflation, punctures, cuts and impact damage may cause tire failure and result in personal injury and/ or property damage. The simple precautions listed below can reduce the chance of problems, and help achieve the expected life of your tires. SPECIFIC PRECAUTIONS ON WINTER TIRES In order to maintain the design handling balance of your vehicle, in all driving conditions, you MUST install Yokohama winter tires in sets of four. As a tire wears out, traction and control are reduced, particularly on snow, slush and ice. Yokohama recommends that you replace your winter tires when the tread depth reaches 4 mm (5/32 inch). Tire Inspection: Visually inspect your tires frequently for any abnormal conditions such as scrapes, bulges, cuts, nails, uneven wear, etc. resulting from operation. This must be done immediately after any suspected contact with an object on the road, a pothole, road irregularity or after severe braking. Immediately refer any of these conditions to your nearest Yokohama dealer for a thorough tire inspection. Tire Loading: Never exceed the maximum vehicle load limits listed on the vehicle placard or in the owner s manual. Be aware of the load carrying limits molded into the tire s sidewall, and do not exceed them. The tire s maximum load limit can only be carried at the maximum cold inflation pressure indicated on the tire s sidewall. Always replace a tire with one of the exact same size, and of the same or higher speed rating. Speed Limits: Regardless of the performance or speed capabilities of your tires, always obey all laws and never exceed speed limits dictated by driving conditions. Hazards: Objects on the road that threaten a tire should be safely avoided. These objects include: potholes, glass, metal, rocks, wood, debris and the like. Unavoidable contact should prompt a thorough tire inspection. Air Pressure: Air pressure maintenance is critical to tire life. Tire pressures must be checked frequently when tires are cold (before operation, when cool to the touch), and no less than once per month and before extended operation. Use a tire gauge to check air pressure, and maintain it according to vehicle manufacturer s recommendations as listed on the vehicle placard or in the owner s manual. Do not reduce pressure when a tire is hot, and do not inflate a tire higher than the limits molded on the tire s sidewall. Do not overlook spare tire inflation pressure or maintenance. Tire Tread: Tires must be replaced when the depth of the tread reaches 1.6 mm (2/32 inch). Yokohama tires are manufactured with tread wear indicators, molded into the tire grooves, which indicate tread wear. As a tire wears out, the tread becomes more vulnerable to the effects of road hazards. Visual inspection therefore becomes more crucial as a tire wears out. Hard Braking: You must inspect your tires after any panic braking circumstance, or after tires have slid on the pavement, as this may have caused a flat spot on the tread of the tire. Spinning: If the vehicle becomes stuck, do not allow the tires to spin at speeds greater than 50 km/hr., and do not stand behind a spinning wheel while attempting to push a vehicle. Speed and force can cause a tire to disintegrate and explode, causing property damage and personal injury. Tire Rotation: To ensure even tread wear and long tread life, scheduled tire rotations are required and are a necessary part of vehicle main tenance. As front and rear tires perform differently, and front- and rear-wheeldrive vehicle tires wear differently, they require unique rotation schedules. For front-wheel-drive and ALL high perfor man ce vehicles, rotate the tires at minimum every 8,000 km. For rear-wheel-drive and four-wheel-drive vehicles, rotate the tires at minimum every 12,000 km. However, if your driving style or vehicle usage results in uneven tread wear or reduced tread life, rotate the tires more often. betiresmart.ca

7 Safety warning Death or serious injury may result from: tire failure due to under-inflation, over-inflation or overloading. Follow the vehicle manufacturer s recommendations as listed on the vehicle placard or in the owner s manual. explosion of the tire/rim assembly due to improper mounting. YOKO/WIN/12-10/E ONLY SPECIALLY-TRAINED TECHNICIANS SHOULD MOUNT TIRES. Follow manufacturer and RMA installation safety procedures for mounting and inflating tires. Thoroughly clean rim, lubricate rim and beads and secure tire to mounting machine or place in inflation cage. DO NOT EXCEED 40 PSI TO SEAT BEADS (275 KPA). THERE IS A DANGER IN INSTALLING A TIRE OF ONE RIM DIAMETER ON A RIM OF A DIFFERENT DIAMETER. Always replace a tire on a rim with another of exactly the same rim diameter designation and suffix letter. I.E.: Never mount a 16-inch size diameter tire on a 16.5-inch rim. Special care in mounting on the rim is necessary to achieve full effectiveness of asymmetrical and directional tires. Tire sidewalls are appropriately marked. Register your tires!
