How me design my drift tire setup! (I have odd wheel sizes)

[Tjk2world]

I drive a KA-T and I want to start drifting.
I have four 17x7.5 (grey ones) sport comp wheels running tires:
215/45's
I have two 17x9.75 (black ones) xxr wheels running
255/40's

I have no idea whatthe offsets are but i have pictures included to try and give you guys an idea.

My plan is to daily the car and drift it here and there. I'm assuming i would run the wide rims in front and the skinny ones in back. Since i would have 4 skinny ones i could swap them out when i burn them.

Is this tire setup ideal? Should i change the tires (i have to stick to the wheels i have)?
Is there a more common tire I could use on the wide ones? Everywhere I talk to says the are a very uncommon size.
Should i change to 255/45 to match the back? 245/45? 245/40? Im lost when it comes to tire science. Thanks in advance.

Yes I searched, but i need someone to help me work with what i have.
