I have found the two tires I use most for my truggy is gridirons. And I beams. I have ran impacts. And hole shots city blocks. But I get better performance from the two I just mentioned. Those two seem to cover most tracks I run on. Every time I show up to a track my first practice run is on I beams super soft. Bc they seem to be the most Versatel. Small pin tires seem to punish me when I get of the grove. I beams are more forgiving. My 2 cents! Lol!
