Wheel fitment help

[that1guy]

Am planning on upgrading wheels and tires in the next week. I have a couple of questions and see if you guys can help me out. I tried doing a search and nothing really helped. I will be installing a leveling kit when I get the tires and wheels.
I planning on running Nitto Trail Grappler tires, will 255/75/17 be ok ?
The wheels am getting are XD Addict in 17x9. They have two options which is where am confused both are 6x135 but one has a offset of 18 and the other has a offset -12 not sure what offset I need to order?

i would go with the 18 personally...it deals with the back spacing of the wheel...so like concave vs flat vs deep dish...it may also but not always make the tires stick out more or less...are you having them shipped to you or will u be buying from a store? if buying from store do a test fit where they put only the rim on and turn it...look to see if the rim is hitting the brake calipers...most places will do this but once the tire goes on and u drive off its hard to get them to work with you.

Offset is only part of the picture, what you're most concerned about is backspacing.


These two links explain it better.

Keep the 17s; 18s = No better perf but more expensive tires

For mine, I went with 20" wheels from a 2009 F-150 King Ranch. The fit well and look good too.
