The HG Racing Tyres are the best type of racing tyres in the game for on-road driving, excluding the Devil Tyres. They are sold at the Parts Shop in My City.
They are an upgraded form of the Racing Tyres.
These tyres are not recommended for adventuring within the Choro-Q HG 2 world due to their poor grip on any and all off-road surfaces, though they are still viable on the highway and asphalt roads within the world.
Overall, they are best suited for driving on race courses primarily with an asphalt surface.
