Aftermarket wheel bore size?

[youkefei]

Hi,
I'm considering change my 20" limited rims to some wider aftermarket rims. When I looked into the spec of those aftermarket rims, I saw like Diameter, Offset, Backspacing, Bolt pattern, etc, but I never saw the Bore size. I know my 4Runner is hub-centric, and I'm not a big fan of lug-centric, so I want to find some hub-centric rims.

It may be a stupid question, but where the heck can I find Bore size for custom rims? The rim manufacturers seem don't provide this information.

Thanks!

The hub/bore size of our trucks is 106mm. It's almost impossible(I didn't find any) to find aftermarket wheels that are hub centric. But alot of wheels ,like my Mojave's are actually hub and lug centric. Mojaves have a 108mm bore and the center cap ,with o-rings, takes up the other 2mm.So you get the best of both worlds.Centered and load bearing on the hub and the lugs.

Appreciated, Harper! This dose help!

Okay, for all of us clueless people. What the hell is hub centric and lug centric?

I could just google it, but why don't you tell me anyway. lol

Okay, I found this:

Factory wheels are hub-centric. The lug nuts have a flat seating surface, therefore the wheels need to be mounted on the hub from possible shifting around at high-speeds or when hitting bumps.

Aftermarket wheels are lug-centric since their center bores are large to fit a variety of vehicles. The lug holes on the wheels have a angled seating service (60 deg), so the lug nuts have this same angled design (that is how the lugs nuts center the wheel and are therefore called lug-centric wheels). None of the weight is on the hub anymore, but on the lugs.

Using a hub-centric ring will allow the wheel to be centered as soon as you mount it (like factory wheels), not relying on the lugs nuts to "self center" the wheel. With the rings your aftermarket wheels are now HUB *AND* LUG-centric.

True??

Well, I googled this for you:
Hub Centric vs Lug Centirc

Thank you sir. I got bored and looked it up anyway (see my post above).

So now I've learned something new. Can I go home now? lol

Hey guys, I am planning to buy a set of rims off my friend and just wondering if these will fit.. I know our 4Runner has a 106mm hub bore but my friends rim has a hub bore of I think 77mm.. Is there anyway to make it fit? Will a adaptor/ring work? Thanks guys

You can go from small to large with an adapter, but going large to small isn't an option.

By the way, is the bore size of our wheels exactly 106mm? Or is it 106.4, 106.8, or something similar?

Anyone?

I can get you and EXACT answer this weekend as I still have my 20" green Limited spare out back in my shed and I can measure it. The bore of the wheels is most likely a smidge bigger then the 106mm hub as it's not that tight of a interference fit. I've seen AR wheels for Toyota's that are listed as 106.25mm bore.

106mm divided by 25.4 = 4.173"

huh...400ci small block chevy cylinder standard bore was 4.125"
One of my favorite engines!

Awesome. Thanks!

The reason I ask is because I've been looking at some Fuel wheels, and they offer a 106.4mm bore size in our bolt pattern.

Measured the bore of the rim on my Limited spare today and it was about 4.185". Measured with my cheap bore gauge and miked it. Not as accurate the Bowers XT digital bore gauges we have here at work but close enough.
4.185 x 25.4 = 106.299mm

1O6.4mm bore of the Fuel wheels should be close enough for government work considering a hair is .02-.04mm wide. No doubt,It means they were specifically designed for Toyota trucks if it has a 106.4 mm bore.I really like Fuel's offering of wheels and it would be nice to get some weights of them too.

Thanks, harper. Appreciate the follow-up.

I've been considering either the Fuel "Pump" or "Gauge" wheels, respectively, below.
