I'm getting a new staggered set of wheels 18x11 and 18x9.5, my car is lowered almost to the ground and I need to know a tire size for them

 

there are literally 1.5 million threads on this subject.
unfortunately the question you have asked is relative.

most turds with cars on the ground do some kind of gey stretch thing with almost 0 tire and it looks like dog poop.

i started at my stock tire size, put it in a calculator and just adjusted the size for where i wanted the car to sit and how much i wanted to spend on each tire.

 

Your tire is going to depend on your offset, what you've done to your fenders, and what you're trying to accomplish. You can run stock tire sizes when your car is "almost on the ground". With an 18inch diameter, you've got PLENTY of room to run a good amount of tire or your can really kill the game and run 18's and a skinny/stretched tire with pokeymon wheels. In shorty, as andrew said, there's about 2957049581098579023489279687893145 threads on this ON THIS FORUM and your question is purely relative.

 

Bro, I'm telling you; you need a 375/87/13. ****'ll rule your life.

 

killin' the game with these specs browski

 

Coupe/sedan?

 

I'm sayin, broseph.

Life has forever changed.
