Need something cheap, as long as there is still tread and it works, and the hex isn't stripped, that is fine.
I have a stock set of Nitro Rustler rears. 1 run on them. They still look new. They have racers edge hard foams in them. 20 shipped.
they should fit i believe
As long as it will accept 2.2 wheels. I know it comes with the 2.8 wheels. But the hexes should be the same.
