285/75r18 on 0 Offset – What do I need to know?

[DHBPhoto]

Okay, here's the deal:
When I bought the truck, the dealership installed 0 offset wheels w/ 285/75r18 ridge grapplers. I had them also install Fox 2.5s and a rear ad-a-leaf – in theory they should have been fine, but they RUBBED horribly. Anyway, at the time, the quick and easy solution was to go down a size of tire – wishing I would have been more patient and gone with a positive offset when it came available (live you learn).
But now, I have 40k miles and need to swap tires, but of course, I'm feeling cheap and don't want to spend $1200+ on new wheels, plus $1200+ on new tires, so I'm thinking of trying 285/75r18 on my 0 offset Fuel Shok wheels (which I LIKE a ton!). If I recall correctly, I was rubbing bad on the crash bars and catching the edge of the fender – without flexing the suspension.

Question is: Has anyone else done this? And if so, what did you have to do to get them to fit and NOT rub EVER! I do a lot of 4wheeling, and no, I don't mean dirt roads. I go out in 4Lo a lot. And honestly, I may have to just get over my bigger tire obsession and just buy 275/70r18s again. They've served me well and they seem to run a LOT lighter than 285s.

Rig setup from last spring (will be mounting a Four Wheel Camper Project-M in a few short weeks):

Man, your going to have to cut the crap out of the front end or get a positive offset wheel. Is your truck max tow? If not drop down to a 17” wheel and run a 285/75R17.

Or drop down to a 285/70/18 and keep your 18's....

Offset is the problem. I had no issue with 275/70R18 and Fuel 18x9 +1. I'm currently running 285/65R18 on stocks.

How much positive? +20?
I can get a good deal on Black Rhinos.

Plus 20 will get you where you want. I currently on a plus 12 venomrex 17x9, with 285/75R17.

Gotcha. W/ 0 offset on my 275/70r18, I have no rubbing, unless aired way down and fully flexed. 285/75r17s are only 1/2" or so taller and a 1/4" wider than what I'm running now, so yeah, I'd expect you to be in the clear by a good margain.

I have my sights pretty set on going for the 285/75r18, so this conversation has definitely reinforced my thoughts that a +20 is definitely needed. But, with a new camper topper going on, might have to splurge on new springs before I go full on new shoe shopping... Still fun to fantasize for now.

Thanks for the info!

Did you ever go with the 285/75r18 on +20??

I saw a post with him on gen 3 raptor wheels! On not sure if that was a previous set up or not. It looks killer!

I didn't... I ended finding a set (5) of Raptor Wheels. I threw on 285/75r17 Nokian Outpost AT tires. Zero rub (minus my reservoir hose that I zip tied out of the way) — I could easily have gone up to 315 in terms of fender and wheel well clearance, but I would prob be sitting VERY close (maybe too close) to my UCA. If I ever go bigger, I'll prob do 35x11.5r17 just to be safe.

I think the 285/75r18 would be a super awesome setup, but for $600, I couldn't pass up on that kind of deal for the Raptor wheels. Who knows maybe after amother 45k miles I'll have an itch to go back to 18s and splurge on a +20 wheel.

Here's how it looks now:
