Title: Are Alloy Rims' Bolts Suitable for Spare tire having steel Rim
Post by: polilara on 28 July 2018, 13:55:35
At least they are longer than needed but are there enough space inside both in front and rear axle discs? Just checked that I have air in spare tire but started to think that do I need shorter bolts if puncture...

On an Omega?


They'll be fine.


DON'T use them on a Mercedes!!!

Yes, Omega, Thanks.

Cannot afford Mercedes...

Pretty useless spare if you cannot fit it with the original screws.

You're clearly not thinking in German. After some Wiener Schnitzel and a couple of glasses of Riesling, having to supply shorter bolts to fit the the thinner steel wheel(that's a thinner mounting flange) will make perfect sense. After all, only an idiot would not realise what the pictograms stuck on the spare wheel actually mean!

My Merc comes with another set of shorter bolts for use with the steel spare  ;)

And next door in France, the standard bolts have another taper seat on them for the steel spare. The steel spare has slightly smaller holes than the ally wheels on SWMBO's Citroen.

As does mine. Must be a Merc "trait".  :-\

The bolts for the ally rims are quite long

Surprisingly so.  :y

The alloy wheel hubs are quite substantial, easily 10x the thickness of steel wheels.

The reason for the different bolts is that on a 2-3mm steel hub, the extra 10-15mm of thread will foul the handbrake mechanism... And on front wheels, could potentially foul the hub assembly.

Alloy equipped Ford Transits have different wheel nuts for the steel spare, so not just a Mercedes thing.

So this is not Omega case?? Is the final answer still that in Omega long bolts do not cause problems.

It's a packaging thing... Also, most Omegas have alloys as standard ;)

Be mentioned in the hand book if a problem...

 :y Correct. You use the same bolts for the steel spare as you do for the normal ally wheels on your Omega.  :)

I regard alloy wheels as fashion items, inferior in every way to steel wheels; more expensive, more fragile, more inclined to porosity, harder to fit, harder to remove, attractive to thieves, and no lighter.. All my Senators came on steel wheels, as did some of my Omegas. When I buy new tyres I put them on steel wheels.

At least MB provide a spare wheel of sorts, together with a set of short wheel bolts (cost 50p?) and presumably a jack and wheel brace. My sister's Mokka came with an aerosol can of porridge. She has had 2 flats in the last year, and has now bought a spacesaver steel spare.

Sure, for some reason I like also steel ones, perhaps easier to balance, too without playing games with those "glued" parts. Are alloys more rigid? My spare wheel is from 2001, never used. I do not know whether it is a safe solution to use anymore when needed but a crazy idea to buy a new spare.
