yes this is a drag!

Tire w/wheel will be released by GRP Fast tire brand
specially for MTX-3. *Other tires can not be used.

I also think it will be a problem. A single supplier for tires is not good. Afte a while the afermarket started building rims that would work for the Serpent cars, but it was difficult getting rubber at times before that happened.

guess we will have to take a wait and see approach to this.
