John, you are correct. All options should be on the table, but what I personally think this process will fail. My personal opinion. We need to look at what we want as a class. At the same time what are the minimum requirements everyone is looking for.
Do we want a tire that last 3 weekend, 1 season, 3 seasons.
Is the tire choice still promote 'pay for performance' i.e. stickers will be 1 second faster than 3 heats cycles.
Costs?
