Finally, after months of trying I have landed a 2022 Limited 4Runner without third row seating and running boards. Should be available next week.

I intend to add rock sliders and aftermarket skid plates and have been investigating replacement wheels for the Limited 20” wheels to use off road.
Not looking to make a statement with big wheels, just want to fit a nice set of off-road tires like BFG KO2’s or equal without any rubbing corrections needed. Not planning to install a lift, at least initially until I get some time off road to judge if and what lift I really need.

Been reading in this forum trying to get my mind around the options and I have to say it’s a challenge to make sense of it all with so many tire sizes and rims to choose from and since a lot of people are looking to get bigger (taller and/or wider) tires for looks and for true off-road use too.

Here’s what I think I have figured out:

1. Which wheel/tire diameter 16”, 17” or 18” provides largest selection to get desired installed tire height and width – answer appears to be 17” looking at BFG KO2 tires available.

2. Primary spec for Limited rim selection – stay with +15 mm offset and select a tire that is very near the height and width of the original 20” tires that come with the Limited.

3. Once I get the vehicle, I’ll measure clearances between existing tires and potential rub points to know how much variation new tire and rim selection there is to avoid rubbing (Ie do I need to stay strictly to the existing tire installed width or can it be increased any).

4. Best source of rims with +15 mm offset will be other Toyota rims which likely will be readily available on the used market and can save some money. There are enough Toyota 17” rims with +15mm offset that I can find one I like.

5. Selected tire height should match original 20” tire height to keep revs per mile the same. I pull a small tear drop camper in the mountains and concerned about increasing tire OD thus impacting pulling performance too much.

Here’s a link to a very helpful article on Toyota rim technical data that helped me find 17” Toyota rim’s with +15mm offset:

Factory OEM Wheel Options 5th Gen 4Runner - TRD Vs. SR5 Vs. Limited (trail4runner.com)

One correction to the referenced article appears to be the offset for the 16” forged TDR wheels which according to the Toyota parts listing is only 6mm not 10mm.

I know there are many knowledgeable tire guys out there that can help correct me in my current thinking if warranted so any comments or suggestion are welcomed.
