the P38, the Cayenne and the L322 all have LPG so the spare wheel well is taken up with an LPG tank. the spares have spare wheel covers on them in the shed. if you keep the tyres out of the gutter where road detritus collects, watch where you park you'll rarely have a flat..oh and keep an eye on the pressures regularly. the only time in the past 10 years got stuck was when the wife had a blow out on the cayenne, on a dual carriage wat from hitting something in the road which she couldn't avoid. green flag recovered it home
