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
