The weight of tyres

[c-m]

I was looking at some Meztler z6 interacts for when i can afford a new set of tyres, and noticed that they weigh around 6kg each.

Just wondered if any other manufacturers list their tyre wieghts?

Obviously the less weight the better.

I remember in F1 the Michelin tyres could be up to 2kg heavier than the Bridgestone models

less weight = less rubber = shorter life ??

Less weight may also be a carcass using stiffer materials, etc.
I wonder how much a tyre decreases in weight as you use it?
