The optional spare appears to be full size and would take up most of the rear area. Is there an appropriate 'space saver' spare that is compatible?
"18" Lightweight alloy reduced size spare wheel with vehicle jack and toolkit is located in a bag, tethered down to the rear loadspace floor. For added convenience, the bag is expandable so the damaged wheel can be placed in the bag allowing for the rear loadspace to remain clean.
†Loadspace floor will be raised and maximum loadspace volume will be reduced. Please contact your local Jaguar Retailer for more information."
