Hello,

I bought a set of Lorinser RS wheels on Ebay. Can I use the stock lugnuts with these wheels?

"Rare set of 4 Lorinser RS 16x8 wheels in beautiful condition showing minimal wear. Model# RS 90801651 made in Germany. 5x112 et11 for Mercedes-Benz w116 w123 w126 and r107 SL"

Very nice wheels. I don't so you believe you can so you better sell them. I looked on mine and while they may work you may not get enough thread. I will look in morning to see what mine are if nobody answers

The lug bolts for alloys are longer than the bolts for steal rims
Before you drive the car after fitting make sure and rotate the rear wheels while they are off the ground to make sure the nuts arent fowling the handbrake mechinisim

I have the stock 91 15" wheels (I think they are alloys). Where can I buy the longer bolts?

I don't know the depth of the lug bolt holes on those rims, but here's how you figure out what kind of bolts you need:
- Take your stock wheels (spare?) and put a stock lug bolt through one of the holes.
- Measure the length of the thread that protrudes through the rims.
- Put your stock lug bolts in a lug hole of the Lorinser rims and measure how much it protrudes on those.
- The difference is how much longer, or shorter, the thread needs to be compared to the stock 39 mm thread.

Are they cone or ball seat? Might want to put a wad of Play-Do down one of the lug holes to see what shape they are.

Old thread. Bringing back for my own research.

1) I was told today today that my Lorinser LO wheels should take a cone seat. I must assume this is the "standard" 60 degree angle because I couldn't find any other angles even for sale.

2) Thanks for the great idea to verify this with playdough AxelWulff! And I've got playdough! :)

3) I assume the OP has missed a digit on the model number of his/her wheels. "RS 90801651 made in Germany. 5x112 et11" There should probably be another "1" on the end. for a "8016511" or "RS908016511" or "RS 908016511" Model: RS90 , Width: 8.0, diameter: 16, lugs?: 5, Offset: 11

4) Thanks for the Spare Tire idea to verify the required length. I think my LO wheels require a 39-40mm shaft, but I'll verify this later when I head out to the garage.

THANK YOU Benzworld!


EDIT: Verified:
1) Cone seat verified with play dough. There's definitely evidence of these being run with ball seat lug bolts, but it's clear my Lorinser LO wheels were intended to run with conical / cone seat lugs
4) I verified that my Lorinser LO et11 should run with 40mm lugs in MY CAR. 40mm lugs will give me about 13mm in the hub, same as my stock wheels and lugs. That's was just under six full turns with my lug wrench before the lugs fall out. (Hmm... 1.5 * 6 is 9... so I guess the lugs fall out when there's still a few mm in there?? or my math is wrong... or I'm measuring wrong, or don't understand what 12x1.5 means.)

These were a few bucks cheaper for me with about $11 shipping. NEW CHROME PLATED CONICAL SEAT LUG BOLTS WHEEL LUGS | eBay That's what I bought. Seems identical.

67mm long, 39mm of thread.

(I don't think there are any true 40mm thread bolts. 1.5" = 38.1mm, but the picture shows "40mm = 1.5 inch"... This is literally splitting hairs.)

Hello,

You are right I did miss a 1 RS 908016511 is what I have.

On the 91 420 the stock lug bolt is 12 x 1.5 x 39mm

So with the cone would 40mm work? I found these on Ebay,

You know, all of what I've said above is based on several assumptions that you should verify:
- Verify Cone Seat vs. Ball Seat: Your Lorinsers also require a cone-seat. WD40/grease a lug hole, and then stuff it with playdough or a similar substance. Check the lug seat. This will most likely verify the cone seat.
- Verify How Far threads should go into your hub: Get an OEM wheel (spare?) and OEM lug bolt, and measure how far the bolt comes out the back. (Mine was 12-13mm... seems small to me, and is only about 6 turns. I'd feel safer if it was a little longer.)
- Check how long your lugs need to be in the new wheels: Take one of your (presumably ball seat) lugs which you say are 39-40mm shaft, and put it in the new wheel. Measure how far the thread comes out the other side. I think you'll get a little more length out of a cone seat, but I'm not sure about that. (I'm hoping to get a little more length out of 39mm shaft cone seat than the 39mm ball seat I have here.)

I think you bought the right thing, assuming different style Lorinser et11 wheels require the same lug type and length. I certainly do not know though.

Report back to the forum to help people in the future with the same questions on the same wheels.

Quick update,

I bought new tires today at Discount Tire and they checked the fitment of the lugs and they worked fine.

BUT one of the wheels I bought is bent... They balanced it and thought it would be ok but I feel a vibration at 65+ MPH.

I also thought the wheels would look better. I am not sure if I should repair the bent wheel or just sell them as is :(

What are the odds of finding one of these wheels used?

A set of 4 in 11 offset are hard to come by, just 1 wheel even tougher. Et 22's come up sometimes.
If you find 2 a staggered set up will work.
If you bought the set at a reasonable price, you probably should have the wheel fixed.

I had the wheel repaired for $160 but now I felt the tire rubbing taking a sharp corner at 20mph. The tires I put on are 225/55/16 (Per tirerack and Discount Tire) should I be running 225/50/16?

Maybe these wheels are cursed?
