I just bought a new 2006 King Quad and it was suggested that I get better tires than came with it to ride on rocky trails.... From the ATV television show, they really reccomend the ITP Terra Cross tire. Does anyone know where they sell these for the best price? Also, what is everyone's opinion on getting bead lock rims? Are they necessary if I don't race around and just take it slow and easy on trails? Again, where can I get these for a resonable price? Thanks.
