D-siders dangerously force car tyres onto incompatible motorcycle rims often using air pressure at levels warned against in tyre industry standards.
Danger: Only specially trained persons should mount tires. Improper mounting can cause tire explosion and serious injury.
Follow these mounting precautions:
- Wear approved eye protection.
- Clean and lubricate beads and rim.
- Centralize rim band and tube to prevent pinching if tube-type rim. *Note directional arrows on sidewall where applicable.
- Lock assembly on mounting machine or place in safety cage before inflating to seat beads.
- Set air hose relief valve at 40 psi.
- Use extension gauge and hose with clip-on air chuck. Stand back with no part of your body within the perimeter of the assembled tire and rim.
- Inflate with core in valve stem.
- Never inflate above 40 psi to seat beads.*
- Spin wheel to check bead seating and alignment.
- *If the beads do not seat by 40 psi, deflate and repeat above procedures. Never use a volatile substance or rubber "donut" to aid bead seating. If the tire is a tube-type, deflate and reinflate after seating to prevent tube wrinkles.
- For 15-inch motorcycle replacement tires, never mount on a 15-inch diameter passenger car tire rim. Passenger car and motorcycle rims actually differ in diameter.
- Never mount passenger car tires on motorcycle rims.
Since that looked like a car-style rim on the rear of that BMW, its unlikely that the safety limit of 40psi
was exceeded in the process of mounting the tyre.
In contrast I read a post where an actual D-sider boasted of using 100psi to force a CT to seat on a motorcycle rim.
