Lug Nut sizes?
 

So after installing my 22"s on my car. My front tire lug nuts go perfectly into the wheel without poking out BUT my back wheels have lug nuts sticking out, even after i installed 30mm spacers on the rear they still poke out..this much.. check out the pic

PLease help! what Should I do?!

thats the effect of offsets... more lip means the face of the wheel moves in more... fronts have bigger brakes which requires the the face of the wheel to be moved out a bit...

btw.. did you use the new lug nuts that came with the spacers or did you reuse your stock lug nuts?

i reused the stock lugs because i thought that the spacers can be used with the stock lugs.. or thats what the instructions said..

thats absolutely wrong. the stock lugs are only long enough for the stock wheels at their stock offsets. when you torque the lugs to 101 ft-lbs, the threads actually stretch to provide the correct tension needed.

with the spacers in, you need longer lugs to have enough thread engaged in order to get to that needed thread stretch. right now, you probably don't have enough threads engaged to be safe when pushed...

rule of thumb on how much thread engaged is needed is, to have the same amount of thread as the thickness of the bolt...

The H&R spacers are fitted to the hub with special wheel bolts provided by H&R, and they have new threaded holes for existing stock wheel bolts. Are you using the stock bolts with tapered seats? Do your wheels have tapered holes or round holes? Are they custom made for the X5, or did you buy them used?

How are the 30mm spacer designed? Are the spacer bolted to the hub first with one set of bolts, then your wheels are attached to the spacer with a 2nd set of bolts? Or does one set of bolts go all the way through from the wheel all the way to the hub squeezing the spacer in between? If it's the former, then I believed that using the OEM bolts should be fine. But if it's the latter design type, then I would definitely agree with Hayaku that your OEM bolts are too short for the application. What's the model number of the H&R spacer?

my spacers get bolted on to the hubwith the provided spacer bolts. Then there are threaded holes for the stock lugs nuts to go into.

Not sure what you mean by this question as far as the tappered holes, round holes, or custom holes go? ... But the wheels were made for an bmw x5. All i did was put 30mm spacers on it that bolt on to your hub and then the spacer has threaded holes for the existing stock lugs

There are two different kinds of seats for the bolts. The tapered kind is conical in shape, where as the balled kind is shape spherically. I believe the stock bolts are tapered. Make sure the wheels have the same shaped holes, or you'll have to buy new bolts to fit the type of seat on your wheels. Inspect your wheels carefully, I don't know the reason why your bolts are sticking out if the wheels are made for the X. Ask the wheel manufacturer; is it DPE by any chance?

yes it is DPE. The reason they "might" be sticking out is cuz the x5 owner that had them on his X he had a 3.0 I have a 4.8...same exact reason why i got 30mm spacers for the REAR is because i wanted the tire/wheel to line up wit the extended rear fender flares of the 4.8 that the 3.0 does not have.

But then again technically the 4.8 wheels are 20x10.5 in the rear..and my DPE's are 22x10 in the rear.That might be another reason why the lugs in the rear are poking out

one way to check is to remove a rear wheel and put the lug bolt into the wheel to see if it seats all the way in with no play. that way you can look from all angles to see if the taper ring on the lug nut does fit all the way in.

however, since the fronts fit all the way in, you can assume the fit is correct as it doesn't make sense for DPE to use 2 different specs when milling just the lug holes.

have you tried it without the spacer to see how the lugs fit in the wheel when torqued down?

What is the size of the lip and what is the offset of the wheel? Your wheel width is 10", and half of this is 5". If the lip is 3.5" and the offset is 25mm, then you have 5-4.5=0.5", which is the thickness of the wheel base, and that's not much to cover the bolt head. If this is the case, then you have to get bolts with shorter head. Try www.evolutionsports.com or www.purems.com. The X5 needs bolts with thread size 14x1.5.

What are the actual lengths of thread of the bolts?

Mine are now 55mm but they are conical shaped.

What would worry me about these threads, unless I have missed something, is you now have less thread actually fixing your wheel to the hub.

from what i understand, he has the H&R Track+ spacers, model DRA which gets bolted to the hub and has new holes for the lug bolts to attach to. and since his spacers are 30mm, the lug bolts should not reach the otherside of the spacer and touch the hub anymore. in which case, the stock lugs would theoretically be fine.

although H&R's press claims that the aluminum/magnesium alloy blend that is use to make these spacers are extremely strong, i have seen otherwise at the race tracks and autocross where wheels come flying off from the shear forces... it's my personal preference to only run spacers with longer lugs/studs that attach to the original hardened steel hub and not to any type of spacer (even for street only driving)

Blimey. If thats the case I totally agree. My spacer is bolted to my wheel by one allen bolt then the longer bolts fix to the actual wheel hub. I would not trust the set up you describe even for road use with the stresses and turning moments involved on an X's wheel. IMO high risk.

exactly.. i've witness 2 race cars that lost their wheels while cornering at a nasa race event... they had proper torque and correct sized lugs... the spacer's threading in the holes were ripped right out. threads on the lugs looked like they weren't damaged (but i suggested to them to get new lugs anyways, or at the very least to do a dye penetration test on them).

this is a concern especially with an empty x5 weighing in at 4919 lbs... + driver = 5000+ lbs on a large wheel with very wide tires, there's alot of force going on in that area...

* deleted * sorry found my answer.

Thanks.

Oh No!
 

Well Imola!
I thought you had the best X5 on this board; but seeing how your lugs stick out. I gotta drop you down a couple of places. :rofl:
Hey I didn't even notice till you mention it. Since you mention it does look terrible. Also I hope your safety is not an issuse.
Act quickly on this fix as I like to rank you #1 again. :)

not takin it offensively, but 1persons opinion aint that important right:rofl: i try hard and keep it clean and the lugs dont bother me that much but thanx for ur concern

I would contact H&R to see how the setup is supposed to look. Another idea would be to contact the supplier you bought them through.

It just doesn't make sense to me that if the bolts are seated properly on the wheels that they would still stick out. If you put the wheel bolts through the hole with the wheel off of the X5 do they still stick out??

yes they do. Im guessin the poke out because my rear wheel before(stock) was a 20x10.5 in the rear...and now its 22x10 in the rear. And when i first had the wheel on without the spacer the lugs poked out. And when i put the spacer one, they poke out, but not as much.

I'm in the same boat.....


open to suggestions...


i have a 3.0 2004 X5.


i have 285 50 19's in the rear.


i have 25mm HR Spacers on the rear... happy with the look.


Local tire shop threw on some chrome lug nuts that stick out a bit..... seem to be ok BUT not that nice to look at......


after reading this thread im kinda concerned with safety......


i have NOOOOOO idea how all this stuff works, would really appreciate some inights


im pretty sure a 2004 3.0 came with a much smaller rim/tire set-up..... my current rims are BMW originals but they are 19's.....



the front rims and bolts went on perfectly no issues at all.


the rears is where the changes came.....



I'd like to have some peace of mind that they are on correctly and safely.


since the last posting on this thread was 2006.... im assuming i am NOT highjacking anyone's posting....


please chime in if you can offer some insights and be nice about it.
