In fact Formula 1 intermediate rain tyres used while rain level is low while Formula 2 and Formula 3 does not have intermediate rain tyres and only full rain blue tyres.
That's an interesting question! It seems that the difference in tyre options between Formula 1, Formula 2, and Formula 3 may have to do with the different performance characteristics of the cars in each category.
In Formula 1, the cars are highly specialized and have a lot of downforce, which helps them generate a lot of grip even in wet conditions. This means that intermediate rain tyres, which have less tread than full wet tyres, can be used when the rain level is low, and still provide enough grip for the drivers to race safely.
On the other hand, in Formula 2 and Formula 3, the cars have less downforce and therefore rely more on the tyres to generate grip. This means that in wet conditions, the cars need more tread on the tyres to maintain traction, which is why only full wet tyres are used.
Of course, this is just a general explanation and there may be other factors involved as well. However, I hope this helps shed some light on the topic!
sure costs as already mentioned not only tyres themselves but even rims.
together with this is the limitation of personneel and logistics: as you all know F2 & F3 teams stay in other paddocks during week ends and reach F1 pit lane with a "train" of a QUAD with a number of trolleys...it would be impossible to have more material to carry. As said even the limited people that have to handle all that is a reason.
