Firestone AFFINITY TOURING S4 FF (S-Speed)
A treadwear grade of 500. That is longer-lasting than 66% of every tire line US regulators have graded. Firestone's own median sits at 460, so this one outlasts the rest of the range.
Wet grip A — one grade below the best for wet grip. Heat B — mid-range heat resistance.
