Rotational Weight of Tire Inserts and Acceleration Feel

Adding an insert puts weight out at the rim, where it both rotates and translates. The common claim that this has an outsized effect is largely overstated: controlled testing shows little steady-state difference. It is felt most in repeated punchy acceleration and deceleration through technical terrain, and that is what it must be weighed against the insert's rim and sidewall protection.
