I purchased maya stm's and i am illiterate when it comes down to tire sizing etc.
the wheel specs are Maya STM 19x 9 F / 19x10 R

ive done research and it seems that a: 245/35/19 F x 275/30/19 R is a popular setup, i have no clue what those sizes actually even mean other than the 19" or if it would even work for my setup. any help appreciated

 

This is a very bad choice, 245/35/19 and 275/35/19 is what you want

 

in my search i saw some people have different size tires, not too sure why that is, but does it give it more of an aggressive look besides obviously the width diff.

 

so this tire size will definitely fit my set up? need to confirm this because i'm getting new tires today lol dont want to be stuck with the wrong tires.
