The V2's are 1.3mm wider and 3mm taller than the traditional size 1:8 wheels. All this transfers into a stiffer sidewall for less sidewall flex enhancing stability and connectivity with your 1:8 buggy. This is achieved by using the same size 1:8 tires that you use now. Simply stretch standard tires over the V2 wheels and you’re ready to go. Proline velocity V2 dish wheel includes 4 wheels total.
