Need help onegai

hi im new to the forum. im filipino, japanese, and white and recently decided to learn Japanese. i was wondering if someone could help me with a phrase?

i was hoping to learn how to say:


i can't get my tires of my car yet



weird i know but to explain is my friend thats teaching me is a racer too and says that speaking it more will help learn it better so im trying


thanks :]

How about:

まだ車からタイヤを外せないんだ。
mada kuruma kara taiya o hazusenai n da.

Not the politest way to say it, but if you're talking to a friend, it should be ok.

Is this a phrase that your friend who is teaching you is able to say himself yet?
