Have had our LR-4 a little over 2 months now and decided to check the air pressure in the tires. First noticed that the tire information placard calls for 36psi front and 42psi rear with identical size tires. (the 19's) Probably related to weight distribution of vehicle. When i checked them they were all around 42-44 psi. Maybe the dealer was trying to get me better gas mileage!
