Looking for VW Ameo highline (released in India) or polo/vento - 4 tyres (front & rear) comes with 4 alloys - good but spare wheel tyre as Steel. The dealer quoting that all cars - Hyundai, Honda, Maruti, Toyota - all have spare tyre in steel wheel. Is it true? and Why?
I wouldn't say "all" of them use steel spare tire wheels, but the vast majority of them will. The main purpose of this is to save on cost. It's a lot cheaper for steel wheels than for alloy. If you keep up maintenance on your vehicle's tires, the spare will rarely if ever need to be mounted on your vehicle. There may always be the odd flat tire, but all in all, it rarely happens. Given that, it doesn't make sense to put a more expensive rim in the trunk which will rarely see the light of day. It makes it cheaper for the manufacturer as well as cheaper for the consumer.
