I would like to see the ability to reuse old tyres during a race weekend, would also like the ability to allocate x number of tyres that can be used during a race weekend. Let's say 16 tyres to complete practice , qualifying and three races, this will really make sure you manage your tyres and driving style very carefully.
Not gonna happen, RF2 tyre data is simply too massive - and it would open for cheaters to mem-sniff and manipulate these data.
Should be possible at least to limit tires by weekend via plugin, but with the new build i dont know if something will happen with reuse old tires also via plugin (if possible this should be a game changing in simulation software) ..... I remember that Kunos had this feature in previous software (netKar pro)
