I couldn't find anywhere a valid explanation about what's a differences between tire type 1, 2, 3, 4 and all the way to 20.
Can someone please light me up on this?
Thank you.
Dry set 1 or dry set 5 exactly the same, unless you have used either of those sets previously for free practice or qualifying. Be careful, some race weekends only have a limited number of tyre sets (eg. 5 sets) so make sure you don't wear them all in free practice and keep a fresh set for qually. Especially if you return to the pits in free practice the tyre set can automatically progress to the next fresh set
