I've used the ruf 3400s tires a lot of cars and the z concept. These seem to work well with many cars that need bigger wheels.
If you want to take pics like mine you need to be willing to spend about $70 bucks on a tv tuner card (ati is what i use) and some $30 on a s-video cable. Then you hook up your ps2 to your PC and capture pics and or movies to your heart's content.
