LancerlotThat decision should give you peace of mind and hopefully, you will never need to use it. As tscaptain so perceptively remarks, should the rolling radius of the 18" rim and tyre be the same as the 19", then there should be no problem, however this is not usually the case. The drive system on the Macan connects all 4 wheels via the transmission (drive) system. It needs 3 differentials to cope with differing wheel speeds, side to side and front to back . There is also provision for limiting drive to any wheel that briefly loses traction. The differential system is designed for transient situations, not ongoing long periods of differing wheels speeds on the same axle, which would confuse the electronics, leading to red warning lights, possible limp mode, poor handling and road holding plus the potential for transmission damage unlikely to be covered under warranty. Just saying …….. Regards, Clive
stevehaleySorry to jump on this thread but does anyone know what size spare wheel will fit a 2017 cayenne s diesel with an adblue tank?

It looks like there should be two trays is that correct? ie something like these although this is missing a few thingshttps://www.ebay.co.uk/itm/VW-Touareg-7LA-2-5-R5-Jack-7L0011031B-Set/174215000531?hash=item289005f1d3:g:M6QAAOSwt3teZSL8Do they just sit on the passenger side of the wheel well?How is the spare secured down? Looks like there is a bolt on top of the adblu that you bolt it down with but with what?ThanksStephen
