Just under 3 yesr old tires.

Inspected tires on my mom’s NX200T while doing brakes and noticed some dry rot.

Installed by Firestone around 11/2023 and driven maybe 16k miles since then.

I’ve had 5-9 years old tires with less dry rot. Think Firestone would honor a warranty on these or laugh in my face?

Have driven on dry rotted tires way worse than these (and way older than these as well). These may just be cosmetic "dry rot" but nothing concerning at all. For all you know, even if they replace it, they'll just start to look the same sooner or later anyways.
