Tire size help
So I just got a steal on some 19x8.5 MMD Axioms from a guy who had never mounted them, 2 of them still have their boxes! Now, I'm new to tire sizing and have seen various tires I should go with on other forums and ect. Right now I am thinking about going with a 255/40/19. Is this the best option or should I go with a 245?
