Winter tires are losing air.

Hello together. I recently had new winter tires tightened up. Within 2.5 weeks I had to refuel 2 times. The master I meant to bring the tire again. That’s good of course. The last time they mounted the tire. My question. What nut do you need for the removal? The mother looks bigger than the 23er(largest) which was present in the impact wrench set. Does anyone know immediately what size it has?
