How do I write off tyres as an expense for p&l?

Just confused for tyres specifically. I do doordash and current tyres have 3weeks or so left in them and will need new ones to continue. Based on my log book I use car personal 25.152% and Doordash 74.847%. Does that mean for my current p&l period I can write 74% of the cost to replace despite that the tyres will last longer than the current period and eoy tax return?
