What happens
Punctures on the A14: repaired properly, or replaced with a straight answer.
Slow leaks are the A14's quiet speciality. Screws, nails and shards dropped from trailers gather in the nearside lane between J7 and J10, and a tyre that collects one may lose pressure over a day rather than all at once. The warning light often comes on around the A43 turn for Corby or as you slow for the Thrapston roundabouts. With no hard shoulder anywhere on this road, roll gently on to the next exit if it steers true, not stopping in lane.
Once the car is parked, the fitter removes the tyre and checks the damage against BS AU 159. A hole of up to 6 mm that keeps away from the outermost eighth of the tread either side qualifies; it is plugged, patched internally, and the wheel is then balanced and bolted back. A wound in the shoulder or sidewall, or internal damage from running flat, means a replacement instead, and you hear the price for either before work starts.
Once you have rung, we can also cover 24 hour tyre service, burst tyre replacement on the A14 and flat tyre help.
