Hub bore sizing. What works?

Just found a set of wheels off a Nissan pickup with a 100.3 hub bore. I’ve seen it stated somewgre that our vans have a 110 hub bore but that seems pretty big. Especially since growler grabbed the toyota wheels with a 106.1 and jammed feeler gauges in there. Question is, what can i get away with?
 
106mm is the smallest centrebore you can use (the front hubs are 105.7mm diameter).
Many aftermarket wheels are 108 or 110mm centrebore so they'll fit on as many vehicles as possible.

Rear hubs are 93mm diameter, so they fit just about anything.
 
Word. Yeah i was just working on the rear and saw they were tiny. The Nissan wheels are going to be way too small to fit the front. Bummer.
So why did you shim your wheels?
 
Most Delica and aftermarket wheels use conical wheel nuts, which centre the wheel onto the studs as you tighten them (aka "stud centric"). The Toyota wheels have flat faced wheel nuts, which don't centre the wheels: the wheels rely on a tight fit to the hub to centre themselves (aka "hub centric"), the wheel nuts then just hold the wheels on.
 
Also thank you @Growlerbearnz I was looking all over for the hub diameter for an L300 to confirm fitment of a 108mm bore rim. I feel 50% less insane now.

what is the cure for this?I bought Borbet rims added General Grabber ATX tires and longish nuts that fit into the holes as you thread them down,Didnt seem like there was any play in them but I could be wrong-The rims came off of a tacoma but were custom rims not stock.The guy didn't include nuts so my tire shop put on a set when they installed the tires
 
take a read at this. something I put together a few months ago when I was trying to understand the lug types.

Lug Nuts...bc why not?

Couldn’t find one solid resource on this and was hella confused due to the crazy amount of names and standards within, so here. Lugs nuts come in many different shapes and sizes. Different names for the same thing, different wheel interfaces, even different angles for similar style interfaces...

Someone correct me if I am wrong but I do not think that wheels have to be hub centric in order to work for a toyota. Its just a method that Toyota chooses. If you take a set of toyota wheels and put them on the delica like Growler did then you need to place a shim between the hub and the wheel bore to ensure it is centered properly. Otherwise it is likely the wheel will be pushed to one side when tightened and will feel out of round when driving.

As for using a wheel that is lug centric, this can work on most vehicles. The only thing to ensure is that the wheel bore is at least the same size if not bigger than the hub. Otherwise they will not fit on.

The other thing to ensure is the that lug nut is long enough and of the correct taper. One needs to ensure the lug doesn't top out inside the nut before fully tightening the wheel and that the taper on the nut and wheel mate properly.

So in your case. I think the question to ask is, is the wheel lug or hub centric?

Easy enough way to tell is just remove a lug nut. Is the lug nut seat on the wheel flat or tapered. if tapered, is the lug nut also tapered?

if yes then you are golden. Just make sure the lug nut is longer than the lug itself.

if the wheel turns out to be hub centric, (not tapered at the lug nut hole), then the wheel bore and the hub bore must be the same size. If they are not you will need to shim the wheel.

I hope that’s all clear. Likely I will read this in the morning and make corrections

They do make flat-to-60* taper adapter washers... but IDK if they will eliminate all possible off-center positioning (I kind of doubt they are that tight of a fit).
 
Looks like I have ignorantly gone down this road. The MTs I have on the van are just too loud and since I had some rims laying around I decided to get a second set for road trips. I should be getting the new AT tires back tomorrow. I had them installed on wheels from an 86 4Runner I had laying around with split and rotten tires. I did a bit of research, the numbers looked good. Test fitting one rim and I pulled the trigger...then I find this post...oops? Any luck with using the original acorn nuts to center then swapping in the mag nuts?
I do have another set of Delica aftermarket rims but didn't really like em compared to Toyotas.

Hub centric centering rings exist. Not sure if this is the same shimming GB was referring to, or what issues might exist with these.

For example:



And BTW, I love the new rims. I have kind of a fetish for that style after seeing them on a few Delicas, but didn't know a model/source for them.

Like this guy:

 
Thanks! I've always like them on the 4runner and nice to see these pics with them on a Delica! My friends like the shiny wheels, but meh...they look extra goofy planted on the 4Runner donor

I have ordered the rings I could find in stock and that would get here the quickest. They're nylon, but should get me by until I can get some made of real metal.

I also had to drop a tire size since the rims are about 3/8" deeper. The 235/75s rub at full lock so 225/75s will do nicely(unless I missed something...like shims!) I didn't feel like going the spacer route etc cause I'm lazy. Hell, just caring about rims at all is a push for me.

On side note, apparently 225/75r15 tires are becoming a bit hard to find anything other than street tires or trailer tires! Luckily Toyo has some Open Country AT III that size that I'm excited to try out!
 
This was Growlerz og post.
He went with a center ring adapter, then took it another step and used a feeler gauge to further dial in the centering of the wheel.

Review: TRD Pro SEMA 17"x7" wheels.

Toyota Pro SEMA PTR20-35110-BK (or -GR if you want gunmetal grey). 17"x 7" wide, 4mm offset. About US$200ea from Amazon. You will also need: 24x Toyota flat-face wheel nuts 90942-01058 2x hub centric rings, 106.1mm OD, 93.1mm ID 3x 0.15mm feeler gauges if you want the wheels perfectly centred...

Here's the latest on the Toyota wheels. I ended up using 3 acorn nuts per wheel when I installed the rims to get them centered, at least close, then switched them all to the mag nuts. The mag nuts all lined up quite well. Not sure how it correlates, but I did check the numbers on the mag nuts and wheel holes, about half the nuts total. The nuts were all .683 to .685 the wheel holes were .687 to .689, with a couple at .690. Seems like pretty safe tolerances. I was excited...because...new tires! I tightened everything down and took it for a drive. I think I got lucky and have no weird shimmy or vibration so a temporary success until my proper hub rings show up and I shim the fronts per Growler's plan.

Now the difference between the Comforser muds and the Toyo ATs. Wow! They're super quiet! I can actually hear the engine at 100kph. The ride is smoother without the mud lugs and the rattling in the rear bench seat it gone. There is a glaring negative to the new quietness. The wind noise coming from my front doors at the mirror area. I could barely here it before and now it's quite obvious. It was in the repair list, but the window and door gaskets have jumped up closer to the top of the list!

Thanks to you guys for posting up your prior experience with this so I'm not blindly going about my way with a possibly damaging off center wheel condition. I learned a lot, got led down some new rabbit holes and having never been one to swap wheels, I never knew there was so much to it! Short term/distance I think I'm good, but I now know I should(and will) get it all properly sorted.

Here's the new kicks. I might even clean and polish 'em...maybe.

Does this apply to L400 as well?
 
Interestingly, just today I discovered that my new manual locking hubs are *just* too large for the Toyota 106mm centrebore wheels to fit over. Meaning I had to remove the locking hubs to be able to change a tyre.

I've ground the hubs' flange down now.
