Everyone here who has 19s or 20s has 35 series tires. Why doesn't anyone have 19s with 40 series tires? Isn't a 245/35-20 and 275/35-20 about the same size as a 235/40-19 and 255/40-19. Even though the 19" tire is thinner the sidewall is still taller, for more protection between the rim and pavement.
Please help me with any advice.
