[ "HOW TO READ THE MARKINGS OF A TYREWhen you purchase new tyres, you need to have a clear understanding of three things  tyre size, speed ratings and load index. You must make the correct choice so that you can maintain fuel efficiency, safety and optimal performance. You can get all this information easily. The tyre size you require is given in the interior of the fuel flap or the glove compartment. You can also check the owners manual, vehicle documentation and tyre manufacturer specifications. The tyre size is also written in the tyres sidewall, driver's door jamb and the car's side or backYou need to follow two rules when it comes to Bridgestone tyres reading size The new tyres should match the original tyre size, load index and speed rating specification as suggested by the car or tyre manufacturerNever buy tyres that are smaller than the original ones or have a lesser load capacityThe most convenient way for you to learn about the tyre size is by going through the vehicle documents. The certificate of conformity (CoC) also has the required information. The certificate also contains information on alternative tyre sizesHow to read the tyre size on the sidewallIf you dont have the owners manual nearby, you can know the size of your tyre from the tyre itself. The tyre markings will give you all the information. But you must have a clear idea of which number denotes whatThe tyre width is in millimetres.Percentage height of the sidewall with the widthRadial construction.Rim diameter is measured in inches.The load index (how much load a tyre can carry).Speed index (the highest speed that a tyre can gain).There is also additional information given, but you dont need them to determine the size of the tyre. The documents that you received while buying the car will contain tyre size recommendations. The outer dimensions  width and rolling/diameter circumference is the main factor that affects the compatibility. It is also thought to be a standardised tyre size indicator on the sidewallThe tyre size chosen by you has to compliment the requirements of the car, including load range and speed rating. The full-service description of a tyre of a passenger car must resemble the information laid down in the vehicle documents.Load indexThe load index rating denotes the most load amount a passenger car tyre can carry. It is measured from the maximum permissible axle load range from one tyre to another.Speed indexAnother relevant factor when selecting a tyre is speed index rating. The tyres speed capacity should be equivalent to a car's highest speed. Speed rating gives the maximum speed a tyre can achieve with full load capacity. It also indicates how appropriate it is for the carChoosing the correct tyre sizeAlways adhere to the recommendations of the tyre manufacturers and the vehicle documents when choosing the tyre size. The wheel and tyre diameter have to match together. If not, there will be a marked discrepancy in speedometer readings and ride heightYou must fulfil all legal regulations and requirements and comply with the suggestions of wheel, tyre and vehicle manufacturers before switching to different tyre sizes. Whatever happens, the wheels should rotate freely, and tyre load capacity has to be maintained.There are instances when you can use a different tyre size, but you need to attach the same new tyres (same tread pattern, size and age of the tyre) across the axles. Consult with a local dealer or your car manufacturer if you want to make some changes to your tyresAn approved test centre will rectify whatever needs correction in the vehicle documents. If you don't have approval but still use your car, you are susceptible to accidents and finesAny vehicle must have tyres whose internal construction is bias-ply or radial. It is illegal to fit mixed tyre construction (bias ply and radial) to light trucks, caravans, and cars. You can do this only when you are using a spare tyre in an emergencyThe same guidelines apply in the case of rims or wheels. The conventional rims or wheels that motorists use must have the approval of the vehicle manufacturersTo ensure safety and performance, have all four tyres replaced at the same time. While it is possible to switch out less than four tyres simultaneously, you should follow a couple of guidelines regarding tyre size.Change all your tyres reading at the same time to enjoy optimum performance and safety. If you want to replace one or two tyres, make sure that they are of the exact size and have the recommended speed rating and load index. Moreover, fit the newer tyres to the rear axle wheels. They will lessen the chances of aquaplaning as they provide a higher amount of grip. Try to avoid replacing just one tyre, as it can adversely affect vehicle suspension or transmission and cause excessive tread wear." ]
