[ "Tyres are crucial for driving safety because they are the only element on your car that makes actual contact with the pavement. This handy guide covers everything you want to understand about car tyres. From reading and establishing pressures to determining what size tyres you require. Following the tips from Continental Tyres Stevenage can save you money, reduce hassle, and, most notably, keep you and others safe on the road.What exactly are tyre speed ratings?A tyre speed rating is the top speed that a particular tyre is legally allowed to travel. The rating is properly symbolised by a letter on the sidewall of the tyre. It is always the final letter in the series. The speed rating is W if the sidewall says 205/55 R16 W 91, for example. Each letter corresponds to a maximum speed. Thus a tyre with a W speed rating becomes authorised for speeds of up to 168mph. What is the legal tyre limit in the United Kingdom? In the United Kingdom, the legal minimum tread depth is 1.6mm. This is true for the middle three-quarters of the tyre's width and the whole circumference. To be on the safe side, numerous car makers suggest switching your tyres again when the tread is down to 3mm. Travelling a vehicle on the road with a tyre with less than 1.6mm of tread is punishable by a 2500 fine. Three demerit points on your licence. If all four tyres are under the permissible level, you will suffer a 10,000 fine and 12 demerit points, which will result in a six-month driving ban. What should the pressures in my tyres be?The correct tyre pressures for your vehicle are there on the sticker. Usually within the fuel filler flap, or in the owner's manual. Keep in mind that the automaker may recommend distinct tyre pressures for both the front and rear. You'll also notice different suggested pressures for various types of loads. For example, only two inhabitants in one case and a full household with luggage in another. So make sure you choose the accurate pressures for the load you're carrying.Your tyre pressures must be under the proper limit. If the pressures are too low, the vehicle will feel unstable and possibly dangerous to drive. The tyres will wear rapidly, and fuel economy will decline. If they are excessively high, the tyres would not create as much handle as they should. And the centre band of the tread will wear heavily.How would you read a tyre's markings?A tyre's markings imply its size, load index, and speed rating. A typical tyre designation is 205/55 R16 W 91. The first three numbers - 205 - represent the width of the tyre in millimetres. The second two-digit number - 55 - refer to the aspect ratio of the tyre. This refers to the height of the sidewall expressed in terms of the width of the tyre. As a result, an aspect ratio of 55 indicates that the sidewall is 55% as big as the tyre is wide.R stands for radial. This means the tyre's cord plies are in position at 90 degrees to the direction of travel, thereby adding strength. Radial tyres are in use on almost all new vehicles. The two-digit number that carries, in this case, 16, demonstrates the diameter in inches of the wheel that can be easily fitted with that particular tyre. The final letter represents the speed rating, which is the top speed that the tyre is legally permitted to travel. A speed rating of W denotes a top speed of 168mph. Scroll up to see a complete list of speed ratings. Eventually, the last two digits represent the load ratings of the tyre. In this case, a load rating of 91 means that one tyre can legally carry a maximum weight of 615kgHow to Measure Tyre Tread DepthTo verify that your Tyres Stevenage have had enough tread depth, insert a 20 pence piece into the tread at the juncture in which the tread is shallowest." ]
