    I have 285/70/17 Nitto Ridge Grapplers and I'm looking at a wheel with the following specs...

    17"
    7" width
    +4mm offset
    4.16" backspace
    Hub Bore 106

    Would the tire I am running be better suited to a 8" rim or will 7" be fine?

    Better suited for an 8”, but plenty of people running the pro wheels which are 7” on 285’s.

    The other wheel I am considering is...

    17"
    8" wide
    +16mm offset
    5.12" backspace

    That's what I was thinking too. I don't want the bulbous tire look but I don't know how "bulbous" it would be on this small of a tire.

    I would not choose this one. Poor offset and backspacing

    With a 8" wide 0 offset would be better

    I ran 285’s on 7” Pro rims, no issues as with thousands of other 4Runners.

    Well as I dig deeper I found another wheel that we are honing in on...

    8.5" wide
    4.75" BS
    0mm offset.

    Again, running a 285/70 tire with at least 2.5" of lift. Any input?

    Get what you like, and make sure it fits. Make adjustments if needed after.

    See that's the problem... I come from the Jeep world so I don't know what fits on the 4Runners. And staring down $1k for wheels I'd like to get a little feel good "yeah you're on the right track" before I pull the trigger.

    You are not going to get the type of help you are looking for, I’m afraid. I’ve enjoyed membership on a lot of off-roading forums, and nowhere else is “will it rub” as controversial or as contentious as it is among 4Runner owners, and especially on this board. Some will tell you 285’s will fit without modification, and then when you press them on it they confess that they did have to cut their front fenders and remove the mud flap, but those things don’t count as modification. Others find it necessary to do a body mount shop, or replace the upper control arms with ones that offer more camber adjustment. And folks will buy wheels based on looks and without a thought about the offset, or ignore the offset in favor of a more”aggressive stance”, and then post here asking how to remediate the rubbing. And in these conversations offset rarely gets mentioned.

    I’ve only been on this forum a few months, and regarding fitting 285’s there is a lot to sift through - mostly contradictory. But from what I’ve been able to gather, those who stay at or near the stock offset of +15 have an easier time of it when trying to fit 285’s.

    Thanks for the heads up. I learned the hard way on the Jeeps I had so I don't want to make the same mistake on the TRD. I am doing UCAs as well and my understanding is staying as close to factory is ok IF you are also running a factory width rim. I know that is def one thing I want to change by going wider which means my offset needs to change. I'm not just about looks, I want this puppy to be dialed in when I am done :)

    I thought I saw a rule of thumb ratio of rim width to tire width when it comes to low PSI, and the tire having a lower risk of unseating off it’s bead. I think it was rim should be 70-75% of tire width.

    I am certainly no expert, but I imagine that if a driver spent a lot of time airing down the tires, then rim width vs tire size would be an important consideration.
