Test description
Four (4) new BF Goodrich P205/75 R15 XLM H/T tires were punctured using 3/16” common nails which were left in the tire.
The tires were subjected to a pre - test holographic analysis to confirm structural integrity.
Tires were then placed on a 1989 Chevrolet Astrovan, inflated to 35 psi and driven for 50 miles (80km) with the nails still in them to better simulate a real - world puncture.
The tires were then taken to an independent repair facility where they were repaired using Safety Seal repairs following the manufacturer’s instructions.
The tires were then driven on until treadwear reached the legal limit (when the treadwear indicators were exposed), a distance of 41,351 miles (66,500 km)
Post Test Examination
1. Physical Examination showed no air loss
2. Holographic analysis showed no ply separation or other damage
3. X Ray analysis showed no wire cord corrosion, deterioration distortion or rusting

Conclusion
All tyres successfully completed the 41351 mile test (66,500 km) and all repair locations were deemed sound, exhibiting no air loss or damage
