Hey wondering anybody know whats the best tire additive for a indoor on road track not carpet. We are using 28 and 30 in winter and 36 in summer. Ive tried LRP Blue traction and FX2 but i feel that LRP has good grip but it makes a sound when ever i turn which i dislike FX2 has no sound but not as good grip. Might Gripper is also good with no sound and no odor and good traction but its hard to get. Anything thats really good? Thanks for the advice.
