Aftermarket wheels and amount of threads lug nuts grab onto?

[assassin]

Hello was at the tire shop today and the manager informed me that I should look into longer studs for all 4 corners.

I am able to rotate my nuts about 6-7 full turns (from initial grab to I need to start putting some muscle) with my FN wheels.

I don’t have my factory wheels anymore but I feel like it is a somewhat valid point the manager pointed out.

Anyone else have any input? Would rather not have to replace the studs if I don’t need to.

Thanks!

Look for "Extended Thread" lug nuts, which extend below the seat against the rim. I also replaced my front studs with the longer, OEM rear studs, after almost losing a wheel.

Sounds like ET/Ultra style lugs nuts are what you need. They have extended threads below the conical seat, and are what I'm running on my aftermarket wheels. Lots of thread engagement.

I run ET style lugs also not because I need it but for that peace of mind, and since I was upgrading to aftermarket wheels and needed new lug nuts anyways.

Your other option is to buy longer wheel studs, but thats the more time consuming route.

The tire installer gave you a good advise. 6-7 full turns might be on the low side and this is not something I would be comfortable with. This is the exact reason why I only use OEM rims. If you want to remain as an "assassin", you need to live first.

As long as the lug screws in at least what the diameter of the stud is...You are fine. That's the rule of thumb all engineers use.

what I found on my OEM not modified 2016 runner is the studs are of soft metal.. I do the tire rotations .. do not like the very short studs also .

on my GM vehicles harder studs and longer so with longer stud the nuts will have more friction and not loosen .... more thread more friction so they will have a lesser chance of loosening.

some have changed these OEM studs. used Dorman ..

Don't wat to hijack, but just for clarity: if moving between OEM wheels, all studs and lug nuts will work, yes? I am going from 20'LE rims to 17" 8-holes.

^This^ I had the same "6-7 turns' concerns brought up at a tire shop with my FN wheels. They are all trained based on number of turns (because it's easy), and not able to calculate based on true stud engagement.

4Runner Front Studs are 21.5mm in length with a 1mm inset.

The FN FX Pro is 7mm thick at the hub (with a tolerance of +/- .5mm).

Toyota studs are 12mm in diameter.
21.5mm - 1.0mm = 20.5mm (actual threaded length)
20.5mm - 7.0m wheel thickness = 14.5mm potential engagement.

My lug nuts have an inset appox 1.1mm, which means I have 13.44mm of stud engagement...well above the 12mm stud diameter.

I was curious about this same thing. Recently got a set of countersteer FN wheels and noticed this, but has anyone ever lost a wheel ? Not because it wasn't tightened properly and came loose, but because lack of engagement on the stud.

Has anyone ever heard of anyone losing a wheel from FN on any other Toyota truck ?

ARP 100-7715 is the cure for what ails you. Pricey though.

Sounds like you are good. Stay classy Pony Boy!
