Most light trucks are rated for passenger tires, and often come with passenger tires straight from the factory. Passenger tires are rated for everyday, basic driving. This is fine if you are simply driving your truck around town, but if you want to haul items in the bed, you may find that the passenger tires do not allow your truck to handle as well as you'd like.
Light truck tires are great tires for trucks that will be used as working trucks, hauling and transporting loads in your truck bed. They have a higher load rating and stronger, thicker sidewalls. This is great if you may be traveling in areas with more debris that could hit your tires (such as farms or construction sites). These tires are generally meant for working trucks; if you only haul an occasional load, you will probably be fine with most all-weather passenger tires.
If you would rather have a truck that can handle high speeds and race-like conditions, then a performance tire may be the best tire for you. These tires have large tread sections that grip the pavement for better handling and traction. Also, they usually have some type of special groove design or tread pattern that helps clear your tires of moisture and rain, perfect for slick pavement.
