If you're looking to make a drag car there are some other tires you should get. They are just as grippy, but have a street look to them. They come in a lego kit that is a car that you pull back and it winds the motor. Here's a pic of them on someones overland:
They fit right over the xmod wheels but are just a tad wide. If you have them on the rear, than rubbing shouldn't be a problem... Unless your doing a FWD drag car, which would look so cool! Just remember that your acceleration will suffer big time, because of the taller tires, unless you have motor/battery mods to compensate.
