) to correct any historical or international market inaccuracies below...First 60 series wheels - 16 inch diameter, one piece, 3.5-4 inch backspace (see note about differing widths below)
These are the earliest style wheels to come with 60 series Patrols, and they are the OEM wheel that still seems to be most sought-after today, due to their one piece bead construction, which means the local Big-O tire store can actually still mount tires on them today.
***Critical technical note about these wheels - Even through these are essentially a 16x5 steel wheel, the very early ones (1960~1964) actually have a 4.75 inch bead width, while later ones (65-ish and newer) have a 5.25 inch bead width- Keep this width difference in mind if you are trying to assemble a full set from loose wheels collected from several sources- double check the width on loose wheels before buying ***
In the US market, these wheels were predominantly painted the same color as the body exterior, and came on all Patrols until late 1966 (when several designs changed for 67 (most notably the door handle and latch design).
These wheels were also used on Patrols in the International market well into the 1980's (and the G61 series trucks), where they were typically painted either body color, or gray.
Also, note that these wheels can have hubcap studs, but 99% of them won't:
With Patrols arriving to the US market in late 66/67, the wheel design changed from a 16 inch one piece wheel, to a 15 inch diameter steel wheel with a 2-piece bead. These wheels were most typically silver in color, but with the "deluxe" option would have been painted body color:
(personal commentary- Hilarious that in the late 60's, when other car companies were moving away from 2 piece wheels due to NHTSA concerns about higher highway blowout statistics with 2 piece wheels, that Nissan decided to move in the OPPOSITE direction..
)*** All The 2-piece wheels noted below require a skilled installer to handle- don't expect the local mass-market tire company to know how to put tires on them ***
Lastly- The OEM Patrol wheels that I know the least about (aside from the fact that they exist
) -At some point (in the 1970's) Nissan offered a 16 inch, 2-piece steel wheel, which I have only ever seen on RiverPatrols' Utes; both of which were imported, so I don't think that these wheels ever came on any US market Patrol (again, my understanding (or lack thereof) will be corrected by the guru's who know more than I do about these particular wheels)
Visually, they look very similar to the 15 inch 2-piece wheel, just a larger diameter:
So, you may be asking: "What if I can't find a full set of OEM wheels, yet I want my Patrol to LOOK more factory in its appearance? Or, what if my Patrol has 2-piece wheels and I don't want to deal with the headache of finding a big-rig tire shop to mount my tires?"
I'm glad you asked- Here are some of the "close, but not 100% perfect" matches that I have found in the aftermarket. Note that the 16x6 one-piece Patrol wheel is the hardest to match- they just have a distinct appearance that can't be matched 100%
***Important technical notes about aftermarket wheels****
Patrol Bolt pattern: very common 6 on 5.5 inch (or 6 on 139.7mm) (same used by Toyota, GM, Ford)
However: Center Bore diameter on the wheel is the most crucial dimension- it MUST be 3-7/8 inches (99mm) or larger (not common- most 6-lug aftermarket wheels have a 3.6 inch (92mm) center bore, which WON'T fit over the Patrol's front hub.
Backspacing on the stock Patrol wheels is 4 inches, but any aftermarket wheel with 3.5 to 4 inches of backspace (or better) should work. If you don't want them to rub your pristine stock rear fenders, then FRONT spacing is the more crucial dimension- It's about 3.25 inches from the brake drum face to the inner fender lip on the rear fenders, so the maximum wheel front spacing needs to be about 2.75 inches MAX (2.5 inch front spacing would be better), in order to leave enough room for the tire's sidewall bulge to clear the fender lip.
spec'ing out backspacing and frontspacing is easy: total bead width of the wheel, minus backspacing, equals front spacing. If the wheel is advertised without backspace data, then look for offset numbers- Zero offset wheels mean that the backspacing and front spacing are split 50-50 (so, on a 16x6 wheel, zero offset would mean 3 inches front, and 3 inches back spacing, which is too much front spacing to clear stock Patrol rear fenders.
Here are a few aftermarket wheels I've found that have the correct backspace, the correct bolt pattern, AND a large enough center bore to clear the Patrol's hubs..:
Number one: the only 16x6 wheel that I have found (so far) that would work on a Patrol, and looks anything similar to the original wheels: Wheel Vintiques part number 12-660604

Another 16 inch "it fits, but doesn't look OEM" option are Toyota Tacoma 16x7's. These are wider (7 inch) but have the correct 2 inch front-spacing to tuck into the Patrol's stock rear fenders:

Below are a pair of 15 inch choices...
Toyota 15x6 4Runner wheels: #426013539005 (Personal note: I think that visually, these are the closest match to the original early style 16 inch Patrol wheels, they are just a smaller diameter) https://www.hubcaphaven.com/p/4774/stl6 ... -IQAvD_BwE
Wheel Vintiques 15x6: part number 12-5606358 https://www.summitracing.com/parts/wvi-12-5606358
In the antique truck world, there are old GM truck wheels that would also fit: There are 15x6 and 16x6 GM 6-lug truck wheels that were used from the 50s through the early 70's, but AGAIN: make absolutely sure those junkyard or Ebay 6-lug wheels have a 4-inch or larger center bore before buying)
Hope this helps... please post/add additional wheels that you find which might also be compatible options for these idiosyncratic old 4-bys...
Sorry! I'll blame auto-correct.
