Noticed a tire abnormality and need help with clarification/cause. Khumos that have about 1100 miles on them. Photo is of the left driver side tire. Other tires do not show same pattern. Running 21 psi fronts (255/40/17), 22 rears(315/35/17). Looks like I ran over strips of caulking? I did do a track day 2 weeks ago, hooked on driving beginner, with braking and figure 8 exercise. 4 track sessions. 1 high speed (for me) spin out. 3 hour drive to track should have warmed up tires. Did I cook 1 tire? Suggestions as to what to do if anything?
