About to join the club - wheel offset question

[TuckerGrover]

I’m going to be buying my first JT (had an old YJ in college and loved it) and am making my shopping list. I love the look of Black Rhino product and plan to fit them into the Rubicon trim level. The offset I am finding for the 17x9.5” is -18. How much poke will that likely induce with MT Baja Boss AT’s at 315/70/17? Will I need a level on a stock Rubicon? If yes, how much to achieve and leave enough rake for when I add the Harker Camper Tent setup? What components will this offset likely strain first so I can plan to replace on a shortened timeline? Any other comments are welcome. My use case is daily driver, hunting rig, family trips to the mountains, boondocking’ish when traveling. Thank you.

For the poke question...

that -18 offset with the 315s will stick out a bit, maybe 1-2 inches. A 2-2.5" level should work to clear everything and still keep some rake for the tent. The suspension might wear out a bit quicker, especially control arms and steering, but nothing too crazy.

Thank you! Any brands for the level folks would recommend? I have full suspension and steering picked out, but don’t expect to do that for a year or two. Wanted to get on the trail and decide what my needs will actually be and get some use out of the factory parts.

-18 will stick out a little more than 1-2".

I have +6 and 12.50 wide tires and mine are about 2" past the flare.

Oh man. I’ll have to look at the offset calculator today. I’m fine with a little poke, but don’t want to go too far. I appreciate the image to show it as well. Thank you.

There are areas of my life where that is about right, but in this instance I’d like a little less to poke with, so to speak.

Do you have the narrower (not wide) axles? Looks like you might.

Hahaha, I gotcha. Ya, those specs are not ideal for a jeep. Most run 17x8.5 or 17x9 at the most. I have a set on the way that are 17x8.5 and should sit about flush with the fender.

Rubicon has the wide axles.

Rubicon has the wide axles.

You are right.

When looking at poke pics, the guys with the narrow axles will have 3/4" less poke than you.

Here is my JTRD with a Mopar 2 inch lift with 37 x 12.5 x 17 tires on TeraFlex Nomad wheels with 0 offset. Plus the Harker Camper.
