DRAG tire and wheel combo help!

[Real Boring 240]

Hey guys, i need some advice from any of you experienced people. I want to run some mickey thompson ET drag street radials and i want to buy some extra rims to go with them. I have a buddy at discount tire company who can get me a good price on these but i'm not sure what size i should get. I saw that another member was running the 26x10.50R16 (P255/50/16) and i liked the way it loooked but there are SO much more options with a 15 so i want to try and run them. Now heres the delema, we have 2 real inexpensive wheels we're looking at. one is a 15x7 with a -6 offset and the other is a 15x8 with a -12 offset. i have +50mil rear wide body fenders so i have a little extra room to play with and also, i need to clear coilovers. So what do you recommend?

Tire options:P235/60/15 (26x9.50R15)P275/50/15 (26x11.50R15)p255/50/16 (26x10.50R16)

Wheel options:15x7 -6offset15x8 -12offsetfind something else and quit being cheap?!

thanks ahead for all your help.

these are my 15x8 +25 with zero camber and 235/60/15 bfgs. with the 15x8 -12 you are looking at i think will fit great especailly with the 275/50/15's

Are those Mercedes wheels, or is my medicine wearing off? Also I heard no info on engine, but why would a 240 need 275 section width? Mine will barely smoke both 215s.
