I don't know how I never noticed it but the tire was completely bald on both rears. AND to top it off...1 of the front tires has a nail in it but is not causing a air leak. The guys at Nissan recommended I replace all 4 tires and get an alignment. I only want to change out the rears because my fronts still have about 4-6/32 left on each tire. What do you guys suggest? Should I replace all 4 or just the 2 in the rear, patch the front tire with the nail, and wait for the fronts to wear out?
