![]() Due to the aging of the sidewall rubber, cracks and severe deformation of the sidewall result in the separation of the carcass cord from the rubber. For tires under high temperature, especially aging tires, when side-slip or roll over obstacles occur, it is easy to tear the crown pattern. High temperature will reduce the tear strength, elongation and hardness of the rubber, reduce the adhesion strength between the rubber and the cord, and accelerate the aging of the rubber. ![]() ![]() The correct use, maintenance and repair of forklift tires are very important to increase the service life of new forklift tires, improve the performance of forklift trucks, and reduce operating costs. If the two sides of the same axle are not replaced with tyres of the same factory, the same size, structure, level and pattern, it will accelerate tire wear. ![]() Due to the different load distribution of the front and rear axles, the different working characteristics of the driving wheels and steering wheels, and the difference in road conditions, the wear conditions of the tires are inconsistent. At the same time, wear occurs due to the contact between the tire shoulder and the ground, especially when encountering obstacles, even a small stone can cause the tire crown to burst. It is easy to cause the cords at the sidewalls to break, loose and the curtain delamination, and the force of the carcass cords will exceed the allowable stress and tire ground pressure, the heat generated increases, the temperature of the carcass increases, and the load-carrying capacity decreases. To avoid safety issues or equipment damage, contact Lucas Liftruck today! We'll conduct a thorough tire inspection and replace tires if and when necessary.Under a certain tire pressure, the tire is overloaded to increase its deflection and deformation, and the stress of the curtains and cords increases. This, in turn, limits the vehicle’s fuel efficiency, speed, turning capacity, and stopping power. Worn tires can also have an impact on your operation’s productivity and efficiency as the increased vibration, instability and stress can result in above average operator strain, thereby reducing the operator’s ability to control the vehicle. By avoiding the costs associated with replacing worn out forklift tires, owners can incur far greater maintenance fees down the road as the additional vibration, strain and shock placed upon forklift components can result in equipment failures, downtime and have to prematurely replace essential parts and components. Beyond the immediate safety concerns, there are also financial, operational and productivity risks to take into consideration. While your forklift tires can still be “operational” with significant wear, there are a number of benefits to be gained by replacing worn out or deteriorating forklift or lift truck tires. Like chunking, this is often caused when cushion tires are regularly operated on coarse or irregular surfaces. Chippingrefers to damage to the surface of the tire such as incisions, slashes, nicks, punctures, and divots.Common causes include collisions with objects, repetitive contact with debris or refuse, and driving over coarse/jagged terrain. Chunking as the name suggests, is when large pieces or chunks of rubber detach from the surface of the tire.This causes the rubber to begin receding from the metal band at the center of the tire. Undercutting occurs as a result of overloading and sharp or aggressive steering.Beyond tread wear, other signs that indicate a tire should be replaced include: undercutting, chunking and chipping. Conversely, press on cushion tires need to be replaced after the outside diameter is worn by 1 1/2" or when 30-40% of the tire’s rubber is gone. With pneumatic forklift tires, a tire needs to be replaced after the outside diameter has worn approximately 2” to 3". To avoid accidents, injury or damage, regular tire inspections should be included in each vehicle's monthly maintenance schedule. Determining the exact amount of acceptable wear for a given tire depends upon the size of the tires and the conditions in which it is operated. Note: these figures should only be used as estimations only. Several factors must be taken into consideration here, including the total number of operating hours and intensity of use, driving habits or operator style, application type (i.e., long runs without a load, excessive speed or rotation with a load), operating conditions, the tire type and compound, as well as the vehicle’s average load weight. Rather, maintenance staff, mechanics and technicians must examine a number of factors to determine when it’s time to change your lift truck tires. To date, no exact science or formula exists for determining how long a set of forklift tires will last.
