Tire Guide Tire Structure Tire Sidewall Sizes & Specs Load & Speed Home Help & Support Tire Guide Tire Structure Tire Structure Tread, shoulder, sidewall, bead, carcass, belt, inner liner, and other components are structurally connected to complete the scientific structure of a tire. * Click the buttons to see the names and functions of each part. Tread Part of the tire which has direct contact with the roads surface The tread consists of a thick layer of rubber which comes into direct contact with the road surface. It is highly resistant to fracture and shock in order to protect the carcass and belt located in the tires interior. Rubber with strong anti-inner abrasion features is used to increase the tires driving lifespan. Shoulder The shoulder of the tire Located between the tread and sidewall the shoulder is made up of the thickest layer of rubber in the entire tire, making it easy to dispel heat that is accumulated inside the tire whilst driving. Sidewall The side (lateral part) of the tire Located between the tires shoulder and bead the sidewall protects the carcass and increases ride-ability with its flexible extension and contraction movements. This part of the tire also contains a great deal of information such as the tire type, standard, structure, pattern, manufacturing company and brand name. Carcass The framework of the tire The carcass is the framework of the tire, the most important part. Referring to all layers made up of tire cord where internal air pressure, weight and shock are absorbed. Breaker or Belt The layer in between the tread and carcass The breaker is a cord layer placed in-between the tread and carcass in a bias tire to protect the carcass absorbing external shock and preventing splintering or injury to the tread from coming into direct contact with the carcass. The belt is a strong reinforcement layer located in the circumference between the tread and carcass in radial and belt tires. It's functions are similar to those of the breaker whilst also reinforcing the strength of the tread by firmly tightening the carcass. Bead The part that is in contact with the rim The bead wraps around the end of the cord and fixes the tire to the rim. It is made up of various parts including the bead wire, core, rubber and flipper. In general the rim is slightly tightened so in the case of sudden reduction of air pressure whilst driving the tire will not become unfastened from the rim. Inner Liner The inner liner substitutes for the tube in the tires interior, consisting of a layer of rubber with superior airtight qualities which maintains air inside the tire. The rubber generally consists of butyl, a synthetic rubber or a polyisoprene type.

Tire Pressure - Tire Care Guide | Hankook Tire Middle East & Africa site

Care Guide Tire Pressure Tread Wear Rotation Balance Wheel Alignment Replacement Storage Home Help & Support Care Guide Tire Pressure Tire Pressure The tire inflation pressure is directly related to safety therefore must be checked regularly as correct maintenance can prolong the lifespan of the tires. Learn more about the importance of tire inflation pressure and how to check the pressure of your tires below. Importance of Tire Pressure Optimum air pressure should be maintained to ensure safety, driving performance, tire life and fuel cost. Tires have been known to lose up to one pound per square inch (psi) every month. It is important to check all tires, even the spare, at least once a month or before a long trip. Tire pressures should be checked at least once each month and before every long-distance trip. Tire pressure and tire life Recommended Interval Tire pressures should be checked at least once each month and before every long-distance trip. Tire Pressure Status Low air pressure: It causes the contact patch width to increase, which results in excessive force on the either edge of the tread. Outer abrasion can damage each part of the tire. It also contributes to an increased slope of the sidewall compared to that of optimum air pressure, which can be dangerous. High air pressure: Due to the inflated shape of the tire, like a balloon, the force is focused at the center. The resulting uneven force across the contact patch becomes the cause of irregular tread wear. Checking for Optimum Tire Pressure Hankook recommends that you check your tire pressure once each month. The optimum air pressure level for your tire can be found on the inner side of the car door, or in the car manual (the location of the sticker can vary according to country). The number on the tire sidewall means maximum tire pressure. Therefore, do not apply tire pressure above it. Driver's side door How to Check Tire Pressure Step 1 Purchase a certified air pressure gauge or take your vehicle to a nearby service center or fuel station for a check-up. Step 2 Tires must be checked in a “cold” state (at least three hours after driving). Step 3 Insert the gauge into the valve. Step 4 Compare the measured air pressure level with the level listed on the car door. * If the measured figure is higher release air until the figure matches what is listed on the car door. * If the measured figure is lower insert more air until the figure matches what is listed on the car door.

Wheel Alignment - Tire Care Guide | Hankook Tire Middle East & Africa site

Care Guide Tire Pressure Tread Wear Rotation Balance Wheel Alignment Replacement Storage Home Help & Support Care Guide Wheel Alignment Wheel Alignment To prevent vibration, skidding, noise, and wear, wheel alignment inspection is necessary. Learn about useful information regarding wheel alignment and how to perform an inspection. The Importance of Wheel Alignment If your tires are wearing unevenly, such as the inside shoulder of the tire wearing faster than the rest of the tread, your vehicle may be out of alignment. This conditions not only shorten the life of your tires but adversely affect the handling characteristics of your vehicle, which could be dangerous. If you detect irregular wear, have your alignment checked immediately. Aspects of Wheel Alignment Caster Camber Toe Caster Caster angle settings when compared (from the side) allow the vehicle manufacturer to balance steering effort, high speed stability and front end cornering effectiveness. Increasing the amount of positive caster will increase steering effort and straight line tracking as well as improving high speed stability and cornering effectiveness, whereas decreasing positive caster results in less steering stability. Camber The camber prevents tire abrasion and increases steering manipulation. According to the angle at which the top or bottom portion of a tire pulls inward or outward when the car is on a flat surface, there are three types of camber: positive, negative and neutral. With the development of suspension and auto technology, most vehicles today have negative camber. In the case of negative camber, the car tilts when cornering due to centrifugal force. The outer tires area of contact with the road surface increases, which allows for safe cornering. Toe The toe refers to the directional difference between the front and back of a tire formed by the upper part of an axis on a flat plane. There are two types of toe: toe-in and toe-out. Toe-in indicates the tires front part pulled inward and toe-out indicates the tires front part pulled outward. In the case of severe toe-out, abrasion occurs on the tires inner surface. In the case of severe toe-in, abrasion occurs on the tires outer surface. Both cases experience a high degree of resistance from the road surface, which results in decreased drivability and greater fuel cost. A controlled degree of toe-in increases safety in straight line driving and offsets inner abrasion that occurs due to negative camber. When to Check Wheel Alignment We recommend checking wheel alignment during an annual inspection or for every 20,000 km driven. An inspection is required when, The car has been in an accident. After tire replacement. When there is abnormal tread wear on the tires shoulder. When the handling is unstable and/or wobbles. When ride quality has become rougher or fuel economy has declined.

Tire Labelling - Warranty | Hankook Tire Middle East & Africa site

Warranty Quality Guarantee Tire Labelling Home Help & Support Warranty Tire Labelling Tire Labelling Disregarding any of the safety precautions and instructions contained in this information. Sheet may result in tire failure or explosion causing serious personal injury or death. What is GSO, SASO Label? GSO, SASO Energy Efficiency label for Tire offers helpful information for customers to purchase tires enabling them to check the tires characteristics. Aside from information on the label customers can also evaluate excellent performance results by consulting charts and graphs which detail the running performance and numerous tests. The aim is to lead a market transformation towards a more fuel-efficient, safe and low-noise tire. It will also pave the way for competition to run on tire performance and price, which will in turn stimulate investment in research and development. Labelling Criteria 1. Fuel Efficiency Fuel efficiency is measured by the rolling resistance (RR) of tires. Rolling resistance is the resistance that occurs when a round object such as a ball or tire rolls on a flat surface in a steady velocity straight-line motion. It is caused mainly by the deformation of the object, the deformation of the surface, or both. Additional contributing factors include wheel radius, forward speed, surface adhesion, and relative micro-sliding between the surfaces of contact. It depends very much on the material of the wheel or tire and the sort of ground. Six classes from Very Poor (least efficient) to Excellent (most efficient) Rolling Resistance PCR (C1) LTR (C2) TBR (C3) Excellent RRC ≤ 6.5 RRC ≤ 5.5 RRC ≤ 4.0 Very Good 6.6 ≤ RRC ≤ 7.7 5.6 ≤ RRC ≤ 6.7 4.1 ≤ RRC ≤ 5.0 Good 7.8 ≤ RRC ≤ 9.0 6.8 ≤ RRC ≤ 8.0 5.1 ≤ RRC ≤ 6.0 Average 9.1 ≤ RRC ≤ 10.5 8.1 ≤ RRC ≤ 9.0 6.1 ≤ RRC ≤ 7.0 Poor 10.6 ≤ RRC ≤ 12.0 9.3 ≤ RRC ≤ 10.5 7.1 ≤ RRC ≤ 8.0 Very Poor N/A N/A N/A 2. Wet Grip Wet grip indicates the braking performance of tires on wet road surfaces and is related to the safety performance of vehicles. Tires with low rolling resistance have high fuel efficiency, but can have safety problems. This is because tires with low rolling resistance have low adherence to roads when the roads are wet. Accordingly, the European Council requires tire companies to provide information about their tires adherence (or grip) when applying the brakes on wet roads.
