The wet grip provides you with information on a key safety aspect of a tyre: its grip on wet roads. Tyres with excellent grip in the wet have shorter braking distances on wet roads. To help you make an informed decision, PitstopArabia.com makes the wet grip rating of every tyre, where possible, available to you. A tyre's wet grip capacity is expressed in grades from A to G, with A the highest wet grip performance. These are measured by braking in a car travelling at only 80 km/h. The difference in braking distances between each grade is roughly 3m - the average length of a car. This makes the difference between A and G, 18meters, which is 6 car lengths! This distance could be the difference between being in a road accident or not. These grades are neither applicable nor available for professional off-road tyres, temporary-use spare tyres, studded tyres, tyres used only for racing, tyres whose speed rating is less than 80 km/h and tyres whose nominal diameter is smaller than 254 mm or bigger than 635 mm.
