Hi...having just purchased a new UK spec Sorento XSE fitted with 18 inch alloy wheels I'm was surprized to find the spare wheel is a on a 16 inch rim. Is there anyone with techical knowledge who can advise me regarding this? The RAC legal people tell me to use it would be illegal, but that Kia aren't under a legal obligation to provide a spare. But if they do surely you should be able to use it! The manual describes the spare as a "tempory", marked as only to be used up to 80kph. However the tyre is a 245/70R16 107 with an H speed rating (which is up to 130mph). The really strange thing is that the spare's rim appears to be the regular Sorento's alloy wheel sprayed black, but otherwise identical to the normal alloys.
I'm going to use this car to tow so I really need a reliable spare..you never know!
Thanks for any help :mellow:

Thanks for the replies. I've finally got a definitive answer to my question, thanks to the technical department at the UK Camping & Caravanning Club and the UK Tyre Industry Council. In short(ish) a spare wheel designated by the car manufacturer as a tempory wheel can be used in the event of a tyre failure to a normal running tyre. The proviso is that the overall aspect ratio (the height of the tyre & wheel) must be under a 2% difference, my Sorento XSE is 1.5%. So this means under such circumstances a 16" wheel can be used on the same axle as a 18" wheel, but as my spare has a narrower footprint on the road to the normal road tyres then the max speed should be under 50mph, and care should be taken when driving. Towing can be done with the "tempory" spare but only to get to a place where the regular tyre can be repaired/replaced. :)
