In detail I'm not so familiar with the hole tyre regulations. What if there's rain the whole weekend and fully wet conditions, from shakedown to the power stage and no stage gets canceled because of fog like today. I have read that there are just 8 rain tyres for the whole weekend.

Is it possible for the FIA stewards to allow more rain tyres during the rally when they were needed for safety reasons? i mean no extra tyre fitting zones like in sweden 2020 - just a new amount of rain tyres for the teams that they can use with the regular 8 rain tyres. would this work logistically for the tyre manufacturer? or have the teams to deal with 8 rain tyres and the other tyres and cross it on some stages, like some drivers did today at platak 1 stage, and/or going on full wet tyres for the other stages of the whole rally.
