    Given all the talk about F1 tires and the rule changes this year, I had an idea during the race this weekend, as I watched Ferrari start from midpack yet again.

    Do Michelin or Bridgestone use tires which have a variable hardness through the thickness? At Daytona, motorcycles use tires which are hard on the left side (for the banking) and soft on the right (for the infield). This F1 tire would be different: soft on the outside 1/8" or so, and hard just under the surface through the rest of the tire's life. Soft for good qualifying and the first few laps of the race, hard for durability for the remaining laps.

    Just a thought, Michelin probably already does this.

    Specifically not allowed by the regulations.

    Thanks.
    After I thought about it, it either had to be banned or everyone was doing it.

    Wow, the thing they do with the tires for the bikes at Daytona sounds really cool... I wonder what they look like before and after too.

    I was actually just thinking about this as well the other day, I don't remember why and I don't remember what I thought, unfortunately. :(

    What the tire engineers are more than like working on is a compound that has a soft Duro # for qualifying and then as the tire starts to build up heat it will transform in to a harder Duro #.

    The rules state no dual layer compund tires but like most F1 rules there is too much grey area in it to not disallow for a tire that changes hardness with heat build up.
