Michelin 12C Offset Valve Inner Tube

Fiat 500 on 125SR12 PIRELLI CINTURATO CN54 Tyres

440 - 12 Tyres

• The 4.40-12 crossply size is synonymous with compact classics such as the Fiat 500, most of which fitted 4.40-12 crossply tyres as original equipment.
• 4.40-12 crossply tyres are no longer made by any of the major classic tyre manufacturers. The radial equivalent size is 125 R12, we would recommend switching to a radial.

125 R12 Tyres

• 125R12 is the radial equivalent to the crossply 4.40-12 size.
• 125R12 tyres are fitted to classic cars including the Fiat 500, Fiat 126, Abarth 750, and DKW Junior.
• Our recommended tyre in this size is the 125SR12 PIRELLI CINTURATO CN54, the 125 R 12 Michelin X is also recommended for steadier vehicles.
• We also have the PIRELLI CINTURATO ™ CN54 and Michelin X available with whitewalls for the fashion conscious: 125SR12 CINTURATO CN54 Whitewall, 125 SR 12 Michelin X Whitewall.

135 R12 Tyres

• 135R12 is an uncommon tyre size, typically used as an alternative to 440-12 crossply tyres, as such there is no high quality classic tyres currently made in this size.
• If you require a quality classic in this size, we would suggest moving to 145R12 or 145/70R12 tyres, depending on the specifics of your vehicle.

125R12 Innertube

This 12 C Innertube is of the highest quality obviously manufactured by Michelin one of the worlds leading tyre manufacturers and in our mind the leading manufacturer in classic car innertubes.

The tyre size 125R12 is not a terribly popular tyre size, as original equipment. The majority of the worlds Fiat 500 actually left the factory fitted with 4.40- 12 crossply tyres (this 12 C inner tube is also ideal for a 4.40-12 crossply) However the later of the Fiat 500 cars did fit 125R12 tyres as a later improvement. As a result tied with the fact a 4.40-12 crossply is no longer available, the current go to tyre for a Fiat Cinquecento is the 125R12 Pirelli Cinturato CN54. Because the Fiat 500 wheel rims are so thin they do not have the safety rib wivch makes a wheel suited to being used without an inner tube a Fiat 500 on standard wheels with 125R12 tyres does need an inner tube, and we would suggest the 12C Michelin innertube is by far the best.

Fiat 500 Innertubes
