The job, step by step
Tyre trouble on the A1(M) after hours, repaired where the car is.
Late at night, picture a drive in Hitchin, Letchworth or Welwyn Garden City: the car came home from the A1(M) with a hiss, and a torch shows a nail head in the tread. Morning means the run down to J4 or the M25, and no garage opens in time. The answer is a proper overnight repair that keeps a perfectly good tyre in service.
Keep the nail in, because removing it lets the tyre go down completely, and send us a picture with the size. We dismount the tyre, check the inside for damage from running soft, and if the hole sits within the central tread at 6 mm or less, repair it with a patch-plug to BS AU 159. The overnight price is the daytime price, given before we leave.
