I have the 5.50 R tires and I think they are a better fit for the 19 in. wheels than the 5.00 R 19's. Close rolling distance as for my Firestone distance. Therefore The speed and odometer remain very accurate. I have found that 40# pressure works best for me on my 30 Fordor. I. have also found that no more than 1/16 inch toe-in helps with tire wear and the track or steering is not affected ( no wandering).
