Hoosier R7 NEW (Track use ONLY) estimated 4+ years old – no manufactured date on tires – 5/21 was marked on the tire by my race shop; not sure if that meant manufactured date or received date - no cracks on the sidewalls – some hairline cracks in treadwear dimples (see attached picture) – should be ok to run. With that said, I would still recommend tire tread surface inspection after the first couple of sessions.
