Noticed this sidewall crack yesterday. Car is a 2018 Subaru Legacy Sport. Tires are stock tires. GOODYEAR EAGLE LS-2. I have ~40k on the tires with plenty of tread left. Looking to replace in the next 10 to 20k. Is a crack like this an issue? I didn't look at the other tires because I didn't get time. But I'm sure they have some type of cracks.
