Regear?
yeah a 18x9 wheel will fit your truck and a programmer is like a edge cts or evolution, bully dog, daiblo, superchips, and many others but you don't really have to reprogram but just know that with your new tire size that your speedo is going to be a little off so you might want to find you a speed trap trailor without a cop around and find out how much its off once you get the new tires
