Ty Gibbs’s crew chief says practice runs proved viability of bold two-tire calls

Ty Gibbs won his second race of the season on Sunday at Iowa Speedway, pushing him into second in the NASCAR Cup Series standings with just three races to go before the start of the Chase.

Key to Gibbs's win was an aggressive pit strategy that saw the No. 54 team make three two-tire stops over the course of the race. After a slow pit in the opening stretch of the race, Gibbs needed to win back track position, and the team decided to roll the dice on two-tire stops.
