the :retro" look tire is lighter and more stronger then a rubber made tire. it also obviously doesnt get flats.......they do have a purpose but not on SUV's. Performace cars mostly is what they were made for and tested on.
Eddie, that's why my ST is so fast. I have my tires filled with helium, which is lighter than air. This allows them to turn at a faster rate because they have a lower net gravitational force than traditional air-filled tires.
That depends. Most Sport Tracs take four tires. Mine has a fifth one under the bed, I can't figure out how you drive on it there, so the tread still looks pretty good. However if you're driving an older Morgan you only need three tires.
