Tost Tyre 210 x 65 (2.50-3)• Check air pressure regularly and maintain specified pressure.• Inspect the tyre surface regularly for signs of damage, material separation, foreign objects and flat areas.• Keep tyres free of substances such as oil, grease, brake fluid and tar.• Clean tyres with a rag soaked in petrol, then wash them off with soap and water.• When replacing a tyre, always replace the inner tube too rather than re-installing the original.• As a precaution, always replace a tyre ahead of time (within reason) rather than put the whole aircraft or worse human life, at risk.
