Modern passenger cars run tubeless tires, so inner tubes are now unusual on cars. They still have a place on classic cars, on wire-spoke wheels and as a temporary fix in some situations.
When cars use tubes
- Classic and vintage cars with tube-type tires and rims.
- Wire-spoke wheels, where the spoke nipples make the rim impossible to seal.
- Rims with corrosion or damage that no longer hold a seal — as a short-term measure.
Sizing
Car tubes are sized by rim diameter and a range of tire widths, for example a tube for 175–185/70 R14. Use the size range printed on the box and the correct valve (TR13 rubber or TR15 for larger valve holes).
Tubes in tubeless tires
It is possible, but not ideal. Tubeless tires have ribs inside that can chafe the tube, heat builds up faster and a puncture deflates the tire quickly instead of slowly. Speed ratings may no longer apply. Treat it as a temporary measure, not a permanent repair.
Fitting
- Check the inside of the tire and rim for sharp edges and debris.
- Use a rim tape or flap on spoked wheels.
- Inflate slightly before mounting, then inflate to pressure and re-check after a short drive.
