Ok ok, Vulklon? or bike Tires? Or anyhting else?

I have 4 custom built ali wheels which i intened to add Vulerlon to for grip. But speaking to people etc, that having Vulkerlon might not be worth it with just 12kgs worht of weight acting on the wheels.
So im thinking due to cost and simple and easy to repair, any other ideas of grip to use that i can screw or pop rivit or even bond to my wheels which is worth doing for decent grip? Any Idea?

Thanks in Advance.
