Most vehicles come with the same tire type, tread pattern, size, load index and speed rating on all wheels and manufacturers recommend using the same tires on all four wheels. Very few vehicles have exceptions from manufacturers, and only in such cases can you opt for a mixed set of tires. Mixing tires is dangerous as it sacrifices vehicle handling due to the varied traction at every wheel and also causes rapid tire wear. This means you will be shopping for tires more often if you mix them rather than using the same type on all four wheels.
