My Ultralite is running 17 x 7 wheels. The car weighs in at 1450 pounds without driver. Probably 1675 pounds with driver. I would like to run wider tires (running 235/45/17 DOT's) in the back (the car would make a good drifter since the rear end spends a lot of time about 30 degrees sideways--but sooo good at responding to the throttle). Several people have brought up the point that our very lite cars may not be able to generate enough stick because of the lite weight. I also appreciate someone pointing out that most tires don't have the right construction for the lite cars. What widths are people running on their cars and tire presure (another good point that is opposite the thinking of the fat cars.)
