A series of small weights are molded into the tire, along the center of the tread, well below the surface. At high speed, centrifugal force causes the center of the tire face to expand and rise. This increases the diameter of the tire, decreases the contact patch, reduces friction, reduces carcass squirm
and increases gas mileage.
When the speed is reduced, the rubber of the tire (and perhaps an elastic band) pulls the weights back into line with the rest of the tread. Full contact is then restored, and good handling and braking are as with normal tires.
These tires are only for use in accomplishing high gas mileage. They are not for use in race cars or for rough roads.

I don't know enough about the subject to say anything bad about it, so I'll give a huge, fresh-baked croissant to anything that'll get me better gas mileage with these prices+ |

i would think that the tire already does
something like that on its own because of
centrifugual force. makes sense to me.
plus you gave me inspired by points. bun
for ya |

Adding more unsprung mass would ruin
the handling, and so would decreasing the
contact patch. I'm also not sure if the
centrifugal force would be enough to
counteract the weight of the car on the
tires. You might be able to do this by
changing the tire pressure instead. |

Anything to reduce carcass squirm. [+] |

Yeah, this was inspired by a couple of the other tire ideas posted lately--thanks to them all and the discussions. And thanks for the link to--I was in a hurry. |
|
| |
It was also based on what does happen already. I've seen dragster tires bulging out from centrifugal force. They try to fight it, I'm trying to use it. |

As for unsprung weight . . . yes, that would be increased, but I'm thinking that the tires themselves would flex enough to act as the springs for the centrifugal weights. The halfbaked aspect of this idea is the amount of weights that would be required, and the re-design of the tire bodies--both to be determined by experimentation. |

Decreasing the contact patch would be bad, yes, as far as handling goes. As I said in the idea, this isn't for race cars. Or psuedo-race cars. |
