The one thing that I have noticed, however, is that off-road also seems to affect traction, as when I use the Monster tires at Neo Bowser City, their traction is better than that of the Roller tires. This may pretty much explain why I did so poorly with the Gold Tires when I tried out the pure gold combo; bad handling AND bad off-road is a jinx at Neo Bowser City, but Z'zgashi says otherwise. Of course, the Roller tires offer high handling to counter their weak off-road, but at the same time, their off-road is only second worst (tied with the Slim and Mushroom tires') when compared to the Slick tires and Gold Tires, which have the worst possible off-road.
