Nah forget 18t, #19TForLyfe. Basically anything 74/75GI - 67/69GI is good enough, I should imagine. Once again what Indra said, BUT it would be easier for him to skid on a 18t than 17t. Depends how much he skids though, plus he has a front brake so I doubt he'll wear out any tyres at a Kid Bueno rate.
