I've got a set of 4 AMG Penta 6½J16H2 - they appear to be genuine made-in-germany (marked AMG on the outside, ATS and Made in Germany inside)

They're not in super condition, in particular they've been resprayed not all that well. Quite usable and AFAIK all straight and true (no vibes except when I fitted spacers :rolleyes:) but if you want concourse you'd have to strip and repaint.

Tyres aren't much cop - they old and have fine cracks, although I've been using them with no issues. However, I doubt they'd go through an MOT. Good enough for short term use though.

I think they're marked 112 35 but might be 25. Hard to read 'cos of the extra paint on 'em. I can post a photo if you want to try to read it.

Had 'em on the W126, they sit a bit too far in - with 20mm spacers they looked better. That said, the front hubs, being the longer type, are a pain - I had 2 lots of spacers and 2 goes at machining them to fit, and still had a bit of imbalance on one side unless you fitted the wheel really carefully.

With that in mind, and since they give a smoother ride, I decided to put the 14" 15-spoke set on it instead, so now think I'll sell the Pentas.

Anyone care to give an idea of value? (and I'm aware, before you start, that they're worth more than 50p :D )
 
min 60 per wheel but likely to go over 400 for the set
 
Is there a reliable way to measure it? The clearest one I can read either says 25 or 35, but without taking the paint off it, can't be 100%.
 
Lay a wheel face down on flat surface (doesn't matter if there's a tyre on it or not), lay a straight edge across it and measure as shown by the red and blue arrows

Halve the number you get for the blue arrow and subtract that from the red measurement. That's the ET (25mm in the drawing), distance from the mounting face to the centre line of the wheel
 
Well I measured and they are 35mm offset, which is one of 2 choices for the overpainted writing, so I'll go with that :)
 
I sold a set of 8j 16" Pentas for £400 about a month ago. Wish I hadn't now as I need them.

Mine were good condition and I had them for sale for a while with good tyres. Personally I'd say yours are worth £150 max
 
Gunning, what was the offset on yours?

This et35 set aren't desirable like they normally would be. Wonder what they're from, that's way out of W126 territory. W126 wheels tend to be expensive because it needs to be the low offset.
Still probably worth £250 at least though?

I didn't mean to be rude saying they're worth £150, but I myself had high hopes for the price of mine but just didn't happen. Et11 mine were. Guy put them on his w123. They were all polished too so they did look good with decent tyres all round. 99% of offers for mine was £300
 
I've no idea what they were off. Although usable without spacers on the W126, they were obviously too far in. with 20mm spacers, they looked good.

isn't there a list somewhere of what-wheels-fit-what?
 
looked at the list, none the wiser. The closest in size/offset are the W124, but they don't list a 6½J16 for those. It might be not all are in the list though.

Most of the pentas I see for sale are wider, often 8" or more.
 
Could I make a point here, I don't believe that there is any such thing as a genuine AMG Penta.

I spent a lot of time looking for a set for my W126, and I could be proven wrong, but according to my research there is AMG or there is Penta. The rims were made by two different companies. I think that you will find that AMG's were made in Germany, and Penta's were made in the UK.

My set are Penta P1180, 8x16, et11, which is a good fit with no contact with running gear or body work of the car when fitted with 225x55x16 tyres.

There is a difference in the spokes on the AMG's and the Penta's, but you have to look carefully to see it. The biggest difference is the inner well of the rim. The Penta well looks much like a standard rim with a flat inner centre which steps up to the rim edge, whereas the AMG rim has a large sloped inner well, and is much difference in design than the Penta. However the two rims still fit in the same way. I have an AMG rim as the spare wheel.

I agree with gunning on price, Penta 8x16 would be around £100 a piece, but 6.5 x 16 ? I wouldn't want to pay more than around £150 - £175, as they are no use for the W126.

Penta refers to the 5 spoke pattern.

Hi, again, I must contradict this. I spent months looking at these wheels and what fits what, and the name "Penta" does not mean this wheel in general, it actually only refers to the British made rim.

This from a document from a MB website in the States:

The wider wheel rim is called the P1690 [16x9 et11 vs. the AMG16x9 et0 ], or the P1680 [ 16x8 et11 vs. the AMG 16x8 et11]. The AMG wheels were never officially called Penta’s. Penta is the name of the British company that made the P1680/90. They did this to meet the increased demand for the wheel in the 80s. There are even a few Penta P1680 5x120 (BMW PCD) wheels around.

Officially the real thing is known as the AMG 5-Spoke Road wheel made by ATS. But due to the 'Penta' as in a 5 spoke design and the name of the reproductions the name caught on and has stuck ever since.

But these were far from the only two manufacturers. Others include Compomotive (also British - very similar design to the Penta wheel, not the AMG wheel, but even thinner spokes and a little smaller edge), the Made in ROC unbranded copies (these have no stampings in the front and have made in ROC at the rear but are otherwise exact reps of the original AMGs) and then there are the rarer RG10s (made in Italy by a company called R.G. and these are German TUV approved, exactly the same as the original AMG design except for the centre bore being a standard Mercedes 75mm and not the AMG 66mm).


If you were to contact Mercedes Oldtimer in Germany you will get the same explanation, I know because I did. The official, original, correct name, as mentioned above is "A lightweight alloy 5 spoke road wheel", and the name Penta was only the British made item.



There were a number of manufacturers of the 5 spoke wheels, as well. These were, in no order, Ronal/Centra, ATS, Fuchs, and there were also a number of types of metals, as in there were Aluminium, forged aluminium, cast aluminium and aluminium alloy.


This is the type of discussion that can go on for ever, but it is not restricted to these wheels alone.


I used to have Fords when I was in my teens and twenties, and I had a number of them as rally cars. The thing that I used to get really annoyed about was some-one who was offering Minilite rims for sale. It was the same thing as for the Penta's, you would go and have a look at what was advertised as a "Minilite 7x13 alloy wheel" and then find that it wasn't Minilite, it was Compomotive or BBS, or some other knockoff company. There was, and still is, only one Minilite wheel, and it is made by Minilite still.


So, for my sins, I have British made Penta 5 spoke alloy road wheels on my car, and I also have a couple of original German AMG ATS-made aluminium 5 spoke road wheels, one of which I keep as a spare wheel in the boot of my W126.


For what it's worth.

Incidentally, there are also the differences between the AMG and the Penta of the wheel bolt holes, they are smaller on the AMG than the Penta; and the centre cap has to be the AMG item, as there isn't another type made with a 55mm centre bore, unless it's homemade.

That is concrete enough for me
 
I reckon they'd go nicely on a W124 though, and about the right sort of width. I did have them on the W126 with no spacers - no contact but they did look a bit too far into the arches. 20mm spacers were the answer, and not *too* much hassle - the main issue being to take care when fitting the wheel to tighten it up evenly so it went on straight.

The reasons for swapping, I rather like the mexican hat 15 spokes, and I had a set of 5, plus the taller tyres give a smoother ride, especially with the lowered springs. So far, not much difference in handling either.
 
These, then are 6½J16 et35 112 PCD AMG 5-spoke wheels made by ATS.

Judging by the offset and size, I would say originally for the W124 - although it's kinda hard to tell. Mebbe I'll try asking Merc :) They take a 205 width tyre nicely, would probably also take a 215.
