Hi,

I don't have them on my car but I always thought that when I switch from the current 14" alloys to a 13" wheel and tyre combo' that I'd investigate Steel wheels as a weight saving.

My alloys are about 11kgs a corner with an Avon tyre

I also would swop to steel if they were 13"

These are described as alloy wheels, and looking at the thickness of the material through the holes it would seem to be true.

Manufacturers have spent ages trying to make steel wheels look like alloys, and now they are making alloys that look like steel wheels!

They look like what we mount our snow tires on. They rust easily in a salt envirionment.

these are actually made of alloy hence the ridiculously light weight, if these are fitted with 195 50 15 it's exactly the same rolling circumference as 205 60 13 or if fitted with 195 45 15 the same as 185 60 13

This C5 steelies (alloys) are 15'' x 6'' ET18... Unfortunately there are no 13" or 14"...
And they need special nuts - only from Citroen.

I have "real" alloys - Wolfrace Pro-Lite with same ET18, so if I finish my Roadster I can change to them without problem...

No idea about the 15" but I've got the 16" version of the c5 steel on my hot rod



I got them purely because I needed to run 9j on the rear and it worked out a lot cheaper to buy brand new from Citroen and have them banded


The offset is et 15 on the 16"

^^^^^^^^^^^^^^^^ THAT LOOKS AWESOME

So are the 16" ones steel then, or can you safely band aluminum alloy wheels?

It's only the centre that is ali anyway, not the rim IIRC.

I always thought steelies werent much heavier than alliys anyway, it was the flexibility of steels that let them down.

bashracing - 28/1/13 at 07:42 PM

i know the 15'' are all alloy not just the centre, the so called special wheel bolts are easily adapted into wheel nuts with some wheel nuts off ebay, personally i wouldn't want to band alloy wheels due to the metal turning brittle with the heat cycle of welding

Interesting! Do you know how they are joined together?

froggy - 28/1/13 at 09:22 PM

The 16,s are all steel , can't say I've ever come across an alloy version on any Citroen and I spanner for a living

bashracing - 28/1/13 at 09:24 PM

trust me the one 's in the pic at the top are alloy, i know this because they are mine and have several set's in the workshop, peugeot boys have been using them for years

hobbsy - 29/1/13 at 03:28 AM

Bash is right. I had a set but never ran them in the end. Sold after a cull of the wheels I had as needed the space.

Riveted I would have thought. Although the more I think about it, I can't remember why I think its only the centre that is ali.

EDIT: Apparently i'm wrong, although I have definitely seen 'steel' wheels that have an ali centre. Not sure what from though.

The problem with 'alloy' wheels is that the good 'strong' alloys a) suffer fatigue quickly and b) tend to be very brittle. The fashion to run them on road cars that need them to last for 200k and survive curb strikes without disintegrating means that they usually end up heavier than their steel counterparts.

froggy - 29/1/13 at 09:38 AM

Learn something new every day , the 16,are 6.5j and are just under £30 brand new

steel is ~3x stiffer than alloy - so all otherthings being equal the alloy would need 3x the material for the same stiffness
(aluminium alloy ~70MPa vs Steel at 205/210MPa)

most aluminium alloys are around 2710kg/m³, most steels are around 7850kg/m³
so at 3x the thickness alloy is going to be a little heavier than steel
(and yes I know its not quite assimple as that, but you get the point)

some good aluminium alloys (often heat treated) are as strong as decent steel - but more brittle/less tough and with all aluminium fatuge is always an issue
any decent steel will have good strength, toughness and (if designed correctly to kept withing its elastic limit) not really affected by fatuge
if fatuge (and cost) wasn't an issue we'd all have magnesium alloys on our fast road cars...



so you can make an alloy wheel lighter than a steel, but only if you sacrafice some of its longevity



If I recal correctly the standard steel wheels for the Pug 106 rallye are significantly lighter than most of the aftermarket alloys
I always liked the look of those wheels

yes the s1 rallye steel was 5.5 x 14 and weighed 6.2kg
and the s2 rallye steel was 6 x 14 and weighed 6.7 kg they were made by michelin for peugeot
here's a pic of my old s1 rallye

seriously considering one as my next tin-top

With or without tyres? I've got 17x9 rims that "only" weigh 10Kg so I assume "with tyre"?

Thats without tyre. A 185/60 14 tyre will weigh 7-8kg on its own. They aren't 'that' light, just lighter than the equivalent alloy on a cost basis.

^^ what he said - they are lighter than most steels and the cheaper alloys

Ok, that's cool, was just curious as to what realms people were considering light, thought my 17s were pretty heavy. Tyres for those are abt 11kg each too!
