standard 17" wheels have diameter or 26.74" and 19" wheels have diameter of 29.17" do they reprogam these rigs, cause i want 20s with out getting such low profile. Mine came with 17s which i am going to run in the winter then looking for 20's but to get the 20s at the right height i need to order such a low pro tire. but when and if you got the factory 19s the side wall is much taller. soooooo do i need to reprogram this suv to run a taller side wall on 20s??? thanks in advance.
