I'm getting old

My dad is actually making me pay for stuff now. I don't mind. But I just wasn't prepared for this. I used to always rely on my parents to pay for my major expenditures like insurance, car maintenence, tuition, books etc. But now that I need new tires, my dad's all of a sudden like "oh you have to pay for that stuff now". He should at least put the car under my name since I paid for part of it and since I'm the one paying to keep it maintained. I can't believe he bought my sister who doesn't work a brand new car, but he won't buy me new tires. It makes no sense. I know I shouldn't be complaining at all, but with how controlling my parents try to be they should at least be fair between me and Anna.
