Excuse me for that, I'm new here, I would like to know how it is made the calculation of economy of medium tires with a humidity of x mm in a track that is not raining.

that is totally incomprehensible

incomprehensible? Why?

Don't know what you mean.

What do you mean by economy? Service life?

What do you mean by medium tires?

I'm no F1 engineer or tech but I wouldn't be very concerned about variations in humidity when it comes to racing in the dry. The track and the tire are going to be quite hot, nothings gonna be condensing on it.

I want to know the service life of a medium compound tires in a circuit with a humidity of, for instance, 2 mm.

about 9 :shock:

your question is pretty much unanserable

you need so many variables suspension settings, track abrasivenes, durometer of the tire, heat properties of the tire, driving style track length amount of corners speed of corners

its like asking how much fuel to get a medium bus to the moon if it launches at noon on friday

Mathias, I'm in agreeement with flynfrog. There are countless variables that affect tire life, and each track, each day, and even the tires themselves are changing constantly. There is no graph that can be drawn for such conditions. If there was one, it would be for one track, one generation of tires, one driver, and for one specific weather condition. And one hour later, everything will have changed.
Humidity doesn't have that much difference on tire life, Reynolds number probably is the only thing that relates to it.

what does he mean by "a humidity of 2mm" ?

Mathias can you please define what you mean by "humidity" :?:

What on earth is a 2mm humidity?? :?

Are you referring to the number of laps for which a set of intermediate tyres can be used on a slowly-drying circuit if the current amount of standing water is, say, 2mm?
