How the job is done
Punctures on the A34: repaired properly, or replaced with a straight answer.
Screws and nails shaken off vans and trailers end up along the Oxfordshire A34 as on any busy trunk road, and the gutters of Birmingham's Stratford Road collect their share of glass and metal. A puncture from either tends to be slow, the tyre softening over several miles. On the dual carriageway, avoid harsh braking and head for the next interchange if the car stays steady, since there is no hard shoulder to pull onto anywhere from Wendlebury to Chieveley.
With the car stopped, the fitter lifts the wheel away and studies the tyre from inside. Under BS AU 159 the damage may measure no more than 6 mm and must sit clear of both tread shoulders, and the fix is a combined patch and plug applied from within. Damage outside those limits, or a casing scorched by running soft, calls for a replacement. You are told which, along with the price, before any tool touches the wheel.
