Tan
Actually it would loss of pace on worn tires, but most of the times we would run on worn tires in lighter fuel before pitting so you couldn't actually see that the pace is getting worse in worn tires.
we have a full tank rule in the league. that is, in fact, everyone starts with the same amount of fuel and refueling is prohibited. It turns out that at the entire distance everyone has the same amount of fuel. And the worn-out soft, almost to the cord, rides faster than the new midium or hard. If there was a difference in fuel, then it would still be possible to understand this. But the fuel is equal for everyone. Is there any logic? No!!!
