"Tjerk
The hard tyre seems to be a different story though.
It was actually a bit too fast in testing, and got a bit of a slow-down before release. It may just need a bit more speed. I agree with that view, as I haven't seen it being used enough either. I think the problem isn't the tyre as such, but it's the amount of fuel it has to carry.
There's a very fine balance though, because if you make it too close to the medium on speed, then suddenly the Medium will not be used. If you make it too slow then nobody uses the Hard tyre. There's a tiny, narrow window in the middle where people will have a tough decision to make about which one to use, and that's the sweet spot we try to hit.
