Back spacing help

[05harleyf350]

I have a 2005 Harley f350 with the factory 20s with 275/65/20 tires that are 11 inches wide mounted I would like to put 18x10 wheels with 355/65/18 nitto terra grapplers which are 14 inches wide mounted which offset should I go with to put as much tire under the truck as possible without them rubbing tell me what your running and any pics if possible.

You lifted/lifting? Stock offset is +40. 36.5x14 is not going to clear with out a good sized lift.

But to keep the inside of the new tire in the same spot as the stock tires, you wanna get a 0 offset (14-11=3 /2= 1.5" = 39mm). That would put the new location of the outside of the tire 3" further out. Which with the larger diameter is going to rip apart your fenders, if your not lifted...

Yeah it has a 6" lift but the wheels that I have been looking at have a -10 will these work or will they rub same with the 0 offset will those rub? Does any one have any chrome wheels and tire options that give me a 37 I have been leaning to the xd series crank.

The 0 and -10 offset will clear the inside side of the tire just fine. And with that 6" lift you should clear the outside no problem. Hopefully someone with that setup chimes in soon...
