Which Offset For These Wheels?

I'm looking to get these in an 18x9 for my 08 Silverado 4x4 Graystone Metallic crew cab. I have a RC level and dont plan on doing any other type of lift at this time. I'll likely wrap them in a Nitto Terra Grappler 285/65-18 or 305/60-18.

 

These wheels are available in a +30 and +12 offset. I know the +12 will obviously stick out 18mm more than the +30.

Would the +30 be better since its basically factory offset, even though its a wider wheel?

Would either be more condusive to allowing the 305/60 to fit without any major trimming? I don't mind trimming a little plastic if needed.

 

Which off-set would you recommend?

 

Thanks in advance!

Go with the +12. It will look better and you should not have much rubbing with either tire.

 

Many guys run +18 with both of those tires with no problem. Same thing as 20x9 with 285/55 or 305/50.

I would go with the +12's. 305s on factory bs can potentially rub the sway bar.
