So, do new tires need wearing in? The answer is yes, when you are driving your new car or you have just fitted new tires, gentle driving is the key here. Everything should be done slower, like acceleration, braking and cornering. For the first 50 miles (80 km) don’t exceed 30 mph (50 km h) It takes about 500 miles (800km) of gentle driving and moderate speed to break-in new tires.
When tires are fresh from the manufacturing line, they have a deep smooth tread. The smoothness may cause less grip at first and needs to be roughed up a bit by the tarmac. The thicker tread of the new tires might feel less responsive than the old tires, this is because the new tire have more tire tread flexibility and is called tire squirm. In the manufacturing process they use lubricants so it releases easily from the molds, and this layer of lubricant causes the tire to have less grip on the road.
