All Season tires

primary

This tire has good wet traction, which means that drivers should 
                            expect solid grip on wet roads. As a general rule of thumb, traction can vary based on 
                            driving and maintenance habits and road conditions.

Good Wet Traction

This tire has a good speed rating, which means it can safely handle 
                            speeds between 100mph and 118mph without the risk of failure. As a general rule of thumb, 
                            posted speed limits should always be followed and proper tire maintenance and rotation can 
                            help prevent failure.
