No, these tubes are specifically designed for 12-inch wheels only.
No, this product includes two replacement innertubes only; tires are not included.
Yes, because they feature a standard Schrader (car-type) valve, most bicycle and automotive pumps will work.
The straight Schrader valve has an overall length of approximately 32.22mm.
Yes, they are designed for automotive-grade applications, including caravans, provided the size matches your tire specs.
Check for pinch points or debris inside the tire casing that may have punctured the tube during installation.
Ensure the valve core is tightened and the pump nozzle is fully depressed over the Schrader valve to create an airtight seal.
Before installation, ensure the tire interior is free of sharp debris or metal shards that could puncture the new tube. It is recommended to inflate the tube slightly before inserting it into the tire to prevent twisting. Compatibility is strictly limited to 12-inch rims, supporting the 400-12, 450-12, and 480-12 specifications. To care for your tubes, maintain proper tire pressure as defined by your vehicle or trailer manufacturer, as running under-inflated tubes can cause premature heating and degradation.
