This is a set of two Panther Rattler 2.0 Rear 1/10 Buggy Tires. The Rattler 2.0 is a low profile tread pattern designed for hard packed surfaces, both wet and dry. The tapered edge allows for a smooth mid corner transition, while the middle bars increase forward grip. The carcass design was borrowed from the Switch 2.0 and helps to minimize high speed tire deformation, while the variable ribbed sidewall prevents side wall collapse.
All of this was done in an effort to improve stability at high speed, increase driver confidence and reduce lap times through increased side bite and forward grip, without sacrificing tire wear. The drier the track, the harder the compound of tire you should use (ie: soft when moist, med-soft when dry), and "Clay" compound is ideal for colder weather and or hard packed tracks.
