Your tires are badly worn, and rain is in the forecast. How do worn tires affect your driving on wet roads?
Correct answer: They lengthen stopping distance, make turns harder, and raise the hydroplaning risk.
Why
Your tires are the only part of the vehicle that touches the road. Worn tires are also more likely to blow out during a trip. To check the tread, put a penny into a groove head first: if the tread does not reach at least Lincoln's head, replace the tire.
