wheels and tire size help

[gosu08]

im getting 15x7 wheels and am wanting BFG drag radials to put on there. What is the largest size i can put on there without modifications (rolling fenders etc). This will be only for drag strip application only so i do not car if they bulge out ect.

i have 205/50/15 and they arent doing it for me on accord steelies

i was planning on getting these wheels but do not know what backspace to get.

I run 225/50's on my stock ITR wheels and they work fine. My car is lowered in the front as well and still do ok at the drag strip for me.
