Drag Racing Tech - tire growth

hey guys, i'm trying to calculate which gear I should get for my 12bolt. To do this, I need to factor in how much ET Streets will grow on the top end. I'm probably going to start with a 26-10.5-16 tire. Any ideas?

On my car, the 26x10.5x16 ET Streets grew about 3/4ths of an inch. The 26x10x15 ET Drags grew a solid 1" on the top end. I was surprised at how much RPM I lost when I went to the ET Drags.
