Oh, has anyone actually researched what 200TW means?

We have no idea what the true TW of purple crack might be. Manufacturers are allowed to put LOWER ratings on their tires. For competition tires, manufacturers under rate their tires because we are stupid and equate lower rating with stickier and faster tires.

I would also like confirmation whether consumer reports and other places are correct when they assert that the rating of two identical compound tires is proportional to their original tread depth. Because if those statements are true, the only thing this accomplishes will be purple crack that you can shave to get the old purple crack.
