Summary

Goodyear announced the introduction of a new left-side tire for the NASCAR Cup Series race at Iowa Speedway this weekend.

The change follows a successful test in May involving drivers Austin Dillon, Noah Gragson, and Tyler Reddick. The new tire aims to balance durability and wear, potentially influencing race strategies significantly. Teams will need to adapt to the tire's grip and wear characteristics as race day approaches.
