Radials are not like bias. With age, the radial wires let loose from the bead and they blow out and the wires can do serious damage to the vehicle. A 10 year old radial has outlived its useful life. If you can find a tire shop that sells used truck tires to people on a low budget, they might possibly take them off your hands and sell them to people who are too dumb to read the date code. Otherwise, be prepared to pay a disposal fee.
