[ "All you need to know about tyre load index;The tyre's load rating is the maximum weight that a tyre can carry at a specific speed and inflation pressure. It helps to decide whether to use a particular type of All Season Tyres Coventry on your vehicle or not. For example, consider you want load rating for the following tyres:;Tyre 1 - 80/100-18 with max load 900 kg at 110 kmphTyre 2 - 60/100-15 with max load 650 kg at 100 kmph;If both tyres are run under identical conditions, they will be carrying different weights, leading to additional cornering capabilities. However, they may be running under the same conditions, but they might not have identical G forces acting upon them due to the difference in mass of the vehicle using them. So, if you are cornering or braking with a heavy car, even if these tyres are running under identical conditions, the tyre carrying more loads will have relatively more minor grip than the one carrying lower weightSuspension settings also play an essential role in determining the load rating of a tyre. Using stiff suspension will result in high acceleration and braking, increasing G forces acting upon tyres, leading to a comparatively lower load rating. Also, since any load over and above the max-rated capacity of a tyre can cause failure because it is not designed for such high loads, its always advisable to keep the load as close to the recommended value as possible to ensure optimum durability of your tyreIt is common practice among people who carry goods on top carriers etc., to have tyres with higher load ratings to avoid any problems arising out of tyre failure, which can lead to accidents. To determine the maximum weight a tyre can carry at a specific speed and inflation pressure, it undergoes a series of tests under controlled conditionsThese tests are conducted by using special test equipment. The following parameters are evaluated after testing:;Maximum Load: Maximum load indicates the total weight a tyre can carry without causing damage to itself or risk of failure due to overloadSpeed Rating: Speed rating is determined by evaluating the relationship between a vehicle's capability and the index representing the maximum speed limit one should maintain while driving on that particular tyreInflation Pressure: Inflation pressure indicates the maximum air pressure available in your tyre while loaded to the maximum load rating. The higher inflation pressure you use while running tyres lower their load rating will be. So always use recommended inflation pressures as per vehicle manufacturer's specifications for getting desired performance from your tyresUnloading Test: This test is performed to ensure that a tyre can carry a specific load under unloaded conditions. Since the tyre does not support any weight during this test, it is run at a speed that gives maximum grip and normally 250kmphTesting Chamber: The testing chamber used for these tests is specially designed according to international standards ISO 594 / BS 62275-2:1993. These chambers can apply forces up to 8 times the standard car's axle weight on tyres with safety factors of 3 or more depending upon various parameters like temperature, humidity, etcTemperature Control System: The temperature control system ensures that both environment temperatures and an appropriate temperature inside the chamber remain constant throughout all the tests to avoid any influence on the resultsInflation Pressure Control System: The inflation pressure control system ensures that the tyre is inflated to a uniform pressure at all times during the test. When tyres reach their maximum load rating during testing but bear additional loads, an automatic cut-off mechanism disengages pressures from the chamber. It releases it into a holding tank equalized before being reinvested into the moving rims inside the chamberMaximum Load Carrying System: Maximum load-carrying system allows easy loading of tyre in various positions, i.e., either in normal running position or can be suspended upside down bypassing lift through its center circle to avoid any damage when it comes in contact with the ground while being loaded inside the chamber which is necessary during the testing process of more than two tyres at a timeDynamic Loading System: Dynamic loading system is used to load tires inside the chamber according to vehicle-driven wheel positions required for the tests. This is done by using hydraulic jacks attached to the chamber floor, which are controlled by a servo control system within easy access from the central command consoleShock Absorber System: The shock absorber system ensures no jerks on the tyre while loaded into or unloaded from the chamber. It automatically absorbs shocks due to sudden impact/drop of the car during the lifting procedure inside the chamber. This avoids any damage caused to the Car Tyres Coventry or its rims during the dynamic loading or lifting procedures inside the test equipment." ]
