Install Rating (3rd Party Work 10 = Best, 1 = Worse)
The motorhome chassis from Fiat has NO spare wheel. Punctures are dealt with using shaving foam and a compressor found under the driver's seat!! Hence, the spare wheel which sits under the fixed bed. It is a steel rim but the studs from the alloys WILL suffice on the X2/50.
Better safe than sorry!
The studs from the alloys have the same angle of interface as the steel spare.
