Thanks. Without pictures, it’s really hard to discuss this, since, as you say, one person’s definition may be different than someone else’s.
Do you have a picture of good tyre wear?
That’s the biggest challenge I think. Often I’ve seen delamination described as blistering.
There’s gotta be a good resource out there for reading tires. I know there are books dedicated to tire performance.
@Christopher is a dab hand at reading them in Karting too. Maybe he’ll chime in and impart the basics.
I don’t have any good wear pictures, but the tire should be basically smooth. No bumps, no waves.
