Hubs and electric brakes with Toyota lug pattern

[4000lbsOfGoat]

Hey, I'm curious why SAE lugs don't work? Why would you need them to be metric?

Be gentle, I'm only on my second cup of coffee.

Yeah, sae lug nuts won't fit toyota metric wheels and since it's a lug centric fit it needs to fit properly

Toyota wheels are actually hub-centric (TRD wheels anyway). The problem is that they use mag-seat lugs nuts, that is, lug nuts which have a "shoulder" that slides into the lug opening on the wheel. In order to fit correctly, the lug nut needs to have the right shoulder diameter and depth. The lug nuts made to fit these wheels, with the correct shoulder diameter and depth, are metric (M12). I did quite a bit of looking and could never find an SAE (1/2") lug nut that had the right shoulder dimensions. That isn't something that can be "close enough", it needs to be exact to hold the wheel properly.

I bought my Toyota pattern eletric brake trailer hubs at this site: https://www.southwestwheel.com/c-2-trailer-parts-and-axles.aspx
I put Tacoma 17" wheels on my trailer, close match for my 4runner.
Had to use an adapter/spacer that worked with the trailer hub lugs to change the lug nut type to match the wheels: Circuit Performance 1.5" (38mm) 6x5.5 (6x139.7) Wheel Spacers for Toyota Tacoma 4Runner Chevy Dodge GMC 12x1.5 bought on amazon, but link is dead see description

working great on my build

Hey, thanks for the PHD of answers.

Gorilla makes a set of SAE lug nuts with the right dimensions, I've got a set in one of my plastic bins of bad ideas out in the garage. The main issue that I encountered is the issue with hub vs lug centric. Trailer hubs, by and large, are lug centric. Modern vehicle wheels, by and large, are hub centric; the job of the lug nuts is basically to hold the wheel against the hub. All of the centering of the wheel is done by the lip on the hub that the wheel sits on. Even with the correct lug nuts, the wheel still had some movement agains the lug centric hub and I wasn't confident that it was centered properly on the hub. I wound up using a Spidertrax adapter, which was set up for a lug centric mating with the hub and a hub centric mating with the wheel.

FWIW, if you want to get super fancy, Cruisemaster offers their suspension with the proper hub centric machining and bolt pattern/studs for Toyota wheels. @Teardropper that's the suspension I'm going with for trailer 2.0

Naw. I'm sticking with trailer rims. In the summer, I keep a spare bolted to the back of the Taco's bed. Works for me.

But thanks,

When I researched this issue, it appeared that the stock toyota wheels were both hub centric and lug centric meaning either. But I think all trailer axle hubs are lug centric, at least all three dexters that I have, so it becomes moot. I've used stock taco wheels for a long way with no issues. Dorman makes a lug that is the right metric size and you just need to press out the old and in with the new. I don't remember the number but it wasn't a hard search by size

I used new studs from Currie enterprises. Banged out my SAE lugs from my dexter axle.

Now I can use OEM 4Runner shouldered nuts on my FJ alloy wheels on the trailer.
