Why would you make a rock buggy, but put tires with very low side walls on 20 on it? Me thinks that Xtreame 4x4 is more about bling than anything else. Does anyone else get this impresion? Also on the show where they built the motor for this buggy they put royal purple oil in the motor, but if you go to royal purples web site it says that you shouldn't put their oil in a new unbroken in motor cause the rings won't set. That is one statement that I would take seriously.
