gofas, the 15" TEAM -3 rims I use on the rear are 12" wide and I use bfg drag radials in the rear. I can't help with the 17" off-set but you should PM MOHSUKA (Mike) I think he has 17" on his older WCC. I bought his Team 3 15" wheels when he upgraded to 17". Send us pics once you have them mounted I am interested in seeing these.
