18x12 Wheels fit on stock wheel tubs?

[Ulysses]

Trying to decide drop and wheels. I like the 4/6 that had on my 91 that I daily drove for 10 years. Not daily driving anymore with the 71' but would be a weekend cruiser so comfort is still important. I like the deep dish wide back wheel look. Im on the fence with either 18x9.5 or 18x11.5. I am looking at the Boss 338 and Raceline Executive. There is quite a cost difference but if I can get away with 11.5 wide wheels in a stock stepside bed with 335/30/18 I'm going to go for it. I would consider the executive wheels if no modifications are required. Otherwise I might just go with Boss 338 and do what I did with the 91' and run the continental DWS 295/35/18.

Let me know who has experience or can find a thread to help.

Thank you

Ulysses
