I tried to convert quickly 2 mods from Micmiller from F1 2020 to F1 2021 :
First :
Real tire damage for Slicks, Inter and Wets Version 1.3
Second :
Slicks from gloss to matt. Slicks with more damage, now with holes. 1.5
All credits to him.
For the second mod, i quickly check and obtain that, so i hope it's ok :
Around 10-15%
Around 30-35%
Rebuild due to a possible bug.
