Just a simple database with modified settings to increase the life of the tyres, because CM took the Monzarella catchphrase on the Lotus cars in Italy too literately, and made the tyres worn out like they were mozzarella. The tyres will last 2 to 8 laps longer than before, depending on the track and your driving style.
Thanks to all the guys who posted here: http://www.racedepartment.com/forum/threads/decreased-tyre-wear-10x-flashback.75410/ for their help and feedback.
Remember, this mod works best when playing Career mode with 100% race length. It does NOT work well in Grand Prix mode, nor can I guarantee it will work in Career mode with race length less than 100%.
Have fun racing!
