Hmmmm.....
The stock rear Pantera 15" tires were about 26.5" tall.
335/35x17" tires are .... about 26.5" tall.
I run those, with 245/45X16" on the front and my car sits as low as any I have ever seen. How your car sits is not only a matter of the tires. It is a somewhat a function of tires, to be sure. But adjustable height springs and shock length are also very important.
You can easily have a low car with large diameter tires. Just takes planning.
