SW20 Drag wheel fitment:

Hopefully the pics and info here help you make sound wheel and tire choices. 

Some things to note. A drag radial works better with a slight stretch. 225 on a 9" wheel, 275 on a 11" wheel. The issue is this 275 on 11 fitment will be far too wide for an SW20. You will find most run an 8" wheel to control the side wall section width. Its now up to you to choose a backspacing that puts the tire in a position you are comfortable with. I find the magical fitment is a 15x9 with 6.5 backspacing, but its tough to find this in a good wheel.  Another thing to consider is the SW20 relies on rear squat and soft spring rates for weight transfer. A tire setup that "pokes" beyond the fender lip will require excessive ride height or unnecessarily stiff spring rates. 

 Have a unique fitment to share. Send pics and info to
