It will depend on a wet or dry track. I would expect a dry track so a safe bet in buggy will be BK bars. If you can find them the new panther switch 2.0 will be great as well. Silver losi tapers or Med soft Panther bobocats in the front for buggy. In truck Red kingpins in the morning and Red tapers in the rear or Soft Panther switches in the rear and silver tapers or med soft wookies in the front.
These are pretty standard dry track tires at HRH.
