Make Tyre wear incalculable

In real Formula 1 you may only guess what tyre wear is going to be and how tires are going to behave during the race. In this game you can easily calculate both so participating in races only concists of cotrolling tires temperature and using boost when necessary. Strategy is set up before the race and it only changes when the rain kicks in but it's really rare so most of races are quite boring and you don't need to control any of those car indicators (car, engine, tires, pilots' health). 

My suggestion is to make tyre wear incalculable, so you won't get precise numbers on the pre race runs.
It can just show approximate values or terms like "very low", "low", "temperate", "high", "very high". Also it would be wise to make it partly random and differ every time a little (like this season it's 8.5% on the start, next season it's 9.2%, season after that it's 7.9% etc) , so you won't learn those "hidden numbers" after doing the race for 2-3 times. 

This could add real time strategy making in all kinds of races not only rainy ones and add great value to players' presence in races. 

its a good idea but i think it would only really work if there was no refueling

I like this idea....especially the suggestion of making a random factor in it as if it wasn't for that we would know by data collected previous races. Also in general it makes everything more open. 

This is an old post of mine from another thread: "My whole issue is that tires are too temperature sensitive. It does not matter which type of tire I use I always end up with the same lap times, because on softs I have to use low push levels to keep temps down and on hards i run on default and see no advantage in lap times over any type of tire. Truly the whole algorithm should be looked at. I propose when running on any type of tire on default push should stay in the "grey" zone temp region. This would open up a lot more strategies to use tires and make the tire economy stat a more important stat to research. To counteract too much of an advantage of supersoft then in this scenario tire wear should increase in hot conditions and as tires heat up too much i.e go in the red zone tires wear out sooner and a less predictable tire wear as is the case now. So if you want to push harder you can, tires get hot and wear out sooner but hot tires don't slow you down until they are finished. Just as in real life the harder you push the faster you go to the detriment of tire wear. Hot tires should not slow you down they should eat your tires. So once your tires are on 0% percent is when you should start loosing a lot of time. As for the vote - equalizing tire wear according to race length is a must then the question for using two different compounds in a race becomes obsolete." Meaning that yes tire wear becomes more incalcuable as u start adjusting push levels - more push more wear, less push less wear, default push default wear.
