Because, for the same strength, aluminium alloy has to be thicker than pressed steel. The seat angle is also usually different for steels and alloys. > Or to put it another way, why don't they make the spare, even if it's > steel, the same shape so you can use the same bolts? Some manufacturers do (or did). The steel spares on both my alloy-shod Cit XM and CX had little collars on the bolt holes to allow both to use the same bolts. > As a matter of interest, what is the advantage of allow wheels over > steel ones - why do people pay extra for them? The only thing that seems > to be different is that they don't require hub-caps - a purely cosmetic > difference. Yup, that's it. Cosmetics. There _can_ be an unsprung weight difference, but often (for strength) alloys are heavier than steels - and a couple of kg of unsprung weight makes sod-all difference anyway, especially given the thoroughly shite MacPherson strut & torsion beam suspension on the typical car.

Theres no reason that manufacturers couldn't make good looking stainless steel wheels. They just choose not to bother for whatever reason. B2003

They just choose not to bother for whatever reason. Apart from expense and weight, obviously.

No, I'd have done it. Have done in the past. I've even stuck post-it notes on people's drivers windows in the past when noticing they had a flat in the car park to stop them driving off ... Mike P
