1 In the tire a puncture is taking place at a sluggish pace resulting in a gradual air loss 2 There's a deflation developing gradually within the tire causing it to let out air gradually over time 3 An unnoticed gradual escape of air is taking place inside the tire causing a deflation over time 4 Over a period of time a gradual puncture is occurring within the tire causing it to gradually lose air 5 Unbeknownst to the driver a steady escape of air is happening within the tire resulting in a slow deflation of air over time 6 A gradual puncture is developing inside the tire resulting in a slow release of air over time 7 As time passes a languid leak happens inside the tire causing it to steadily lose air 8 A steady puncture is occurring inside the tire causing the air to seep at a gradual pace 9 The air in the tire is slowly leaking due to a gradual deflation that is occurring over time 10 Over a period of time the tire is experiencing a slow air loss due to a leakage taking place within 11 The tyre is suffering from a slow leak within its structure causing a steady loss of air over an extended period of time 12 A gradual loss of air is occurring within the tyre due to a deflation resulting in a slow release of air 13 An invisible leak is happening within the tire leading to a slow release of air that occurs over time 14 Due to a steady deflation the tyre is losing air at a gradual rate 15 Over an extended period of time the tyre is experiencing a steady deflation leading to a steady reduction in air pressure 16 Gradually the tire is losing air due to a minuscule leak inside it 17 The tire is slowly leaking air due to a steady leakage taking place within it 18 There is a sluggish leakage of air happening within the tire resulting in a slow deflation over time 19 A steady deflation inside the tyre is resulting in a gradual release of air 20 The tire is experiencing a steady escape of air caused by a leakage inside it
