Agreed, but that's for a reason. The 'wide' singles they fit are not much wider than one of the tyres that used to be fitted in twins. Total tyre with of the twin's that the HGV's used to have is greater than the newer singles, less width = less rolling resistance.
Agree about those space savers, they might be rated for temp use but in a AutoExpress test it actually OUTPERFORMED the stock 205 in handling tests! The wide tyre boys wouldn't like that! It was a 115 width I think. If only I could find some legally rated for high speed I'd be happy.
I just think it's crazy we now have access to mfr stock, strong, narrow steel rims capable of supporting the heaviest cars - but can't get any proper road tyres for them.

They are narrow, but they are the same circumference as the regular tire they're replacing.
