How Fat can I go you say?

I wondered if anyone would catch it. The factory fuel tank is temporary, plans for in- trunk fuel cell in the future. When the car is back on the rotisserie I'll be channeling each side of the spare well to make room for pipes.
I only caught it because I went thru the same deal on my dart. I chose to go with 10" wide rims to still be able to run the exhaust out the back, but could have gotten 12" wide wheels underneath it.
