just picked up my Black C III today with alloy wheel, but it doesn't have the wheel lock. is anyone know the spec of the wheel nut? is the aftermarket one will fit? or I have to use Toyota Wheel lock? Is anyone has the C III or IV?? Do you know how to change the radio channel setting?
It's the same threading as the Hondas in your sig. Stock nut size on the steel wheel is 21mm vs 19mm on the Hondas. http://priuschat.com/forums/prius-c-main-forum/105235-prius-c-steel-wheel-specs.html
Don't waste your money on the wheel locks, the likelihood of someone stealing a set of OEM Prius wheels, or even a set of dealer installed premium wheels is slim to none.
