Anyone got pix of some 15x10 (with 4" backspacing) wheels with P295/50R15 on the rear of a D150 81-93 wide bed. I had some on a 81 Ram stepside & they were flush with the edge of the fenders & looked perfect, but not too sure about how they look on a wide bed, would they stick out?

Yes they will.
These are 16x10 with 4" b.s.

a 10" rim with 4.5 backset would be just right. my 10" rim with 3.75 backset stuck out just enuff to rubb the fender lip with a heavy load running 32x11.5x15 mudders.

with stock truck rear axle width,a 10" with 7.5 backset and tubb job you can stick a 29x15x15 M/T in the fenders on the wide box

yeah im probably leaning more toward 15x8's all around with P275/60R15 since it's a wide bed, but if i do get lucky enough to find a stepside bed then i'll go with the 15x10's on the back again like my last truck.

15 X 8s with 275/60/15s with 2.5" lowering shackles

wide box

Well I thought I seen a 80's wide bed a long time ago with 15x10's & P295/50R15 and they stuck out alittle but on my stepside they were flush with the fender lip edge. The wheels I had on the stepside then have a 4 inch backspacing u can see in the pic that they look pretty flush with the fender

295 50 15 t/a on 15x10 .... looked a bit small in dia if you ask me

Thats the pic I was looking for, they do look small in diameter on a wide bed, im gonna go 60's all around and they are taller than the 50's, thatnks for the help guy & the pix

Part of the reason they look small is do to the height. This pic is a 195/75 on a 2wd. Now imagine the tuck sitting 4" higher because ridge Ran this size on the powerwagons stock. I ran 295/50s on 10" rims but mine were 3.25bs or something like that
