Spare wheel steel v alloy (1 Viewer)

[BobRivers]

I'm looking at purchasing a spare wheel for our Motorhome we have the standard 16" 225/75/R16 Alloy wheels on a fiat chassis 5 bolt 118 PCD. Preferably I would like to get a spare alloy wheel due to weight but the cost in my opinion is not worth it plus the fact that I hope I will never have to use it. What I would like to know is if you use it temporary does this have an effect on the driving on the vehicle with 3 now being alloy and 1 steel? Apologies in advance if this sounds like a stupid question.

It'll drive fine. I've had several cars with a steel spare. Some had '50mph max' on them (despite being a regular size tyre). Some did not.

I believe you'll need a different set of wheel bolts for the steel wheel. My camper certainly comes with a set.

I fitted 5 bolt 118 PCD 16" alloy's and bought a 16" 5 bolt 118 PCD steel wheel for a spare.
The offset on all 5 wheels is the same as are all 5 tyres the same, so it will make no difference as to whether it's a steel or alloy on any of the corners and a steel and alloy are about the same weight.

Don’t think there’s a lot of difference weight wise
The newer Ducato’s don’t need different bolts we have a 2018 with alloys and same bolts can be used on steel we have steel and never used also on previous van never used

Fab. One less thing for Bob to buy.

My base is slightly different, which may explain why I need them? A 2021 Citroen relay with the 130 PCD wheels.

I wouldn't be surprised if alloy wheels weren't heavier

Apart from the cosmetics, alloy wheels reduce unsprung weight, thus improving handling, but doubtful if one would notice the difference in a 3500kg MH!

I made it home from France somewhat cautiously on a rusty steel wheel and (very old) spare tyre that didn't match the 3 alloys and newer tyres.

It seems to me that alloy wheels made for 3.5 tonne vans are mega thick, very strong............ and very heavy

For anyone interested a 16” steel rim for Ducato is 13 kg
16” alloy rim 11.10 kg
1.9kg x4 hardly worth worrying about

I rest my case...

And alloys tend to have more of their mass nearer the rim. So their rotational momentum might actually be worse than a steelie...

And me.

I just carry a new tyre carcass as a spare and do without a spare wheel

That's what I would have done if we have a garage in our van.

There is less than 1lb difference between the van's alloys and the steel spare on my Renault Master.

I was amazed how much my 16" alloy spare wheel weights. I don't even carry it any more, it cuts down my spare payload by far too much.
