bobby...if u really wanna safe guard ur wheels...use 5 different lock nuts! although u will be nuts when changing tyres

, but its safe lor.
however, dont have to go that extreme...2 set of different lock nuts will b sufficient.
however, the best bet will b wher n how u park ur car. dont park in secluded area n in shopping complexes, park in bright area. always park inside ur home, not outside...
btw, hows everyone CNY? just came back from Ipoh n its jam from Bkt Beruntung to Rawang. dont know whats it all about thou...
