The tires do mount the wheels different from the other models I built and it's more like mounting a real tire ( kind of ). About the white stripes on a yellow car...... I can't disagree with you we all like what we like and I thought about painting black stripes on to tell you the truth but decided against it. i think the white stripes kind of tie in with the interior stripes and to be honest was looking to do something that is not the same old, same old.
