When do you need new tires on your car?

When the tires wear down to the wear bars. Wear bars are a set of raised lines located in the main grooves, between the tread, that run around the circumference of the tire(usually 3 or 4). These bars indicate when the tread is down to the min. (2/32nds). You will see a line form across the grooves when replacement is needed. 2/32nds is the minimum tread depth, aqua planning becomes a big concern at/below this tread depth. Another way is to use a penny and if Lincoln's head is hidden by tread, the tire is still ok, if it is not, the tires need replacing. Other factors are if the tire is dry rotted( rubber is cracking like a dry lake) of there is signs of damage, bubbles, deep cuts, feathering, cupping.
