At the car
Beyond repair in Islington and the car is needed now.
A tyre in Islington is finished when a Holloway Road pothole has bulged the sidewall, a kerb in Barnsbury has cut through to cord, a run-flat has been driven from Archway to Angel deflated, or a puncture sits too far towards the shoulder. The car is on a resident bay with a permit and a job or a school run to make. No repair kit will hold that, and a tow to a garage means losing the bay and the day.
Photograph the sidewall so every part of the marking is clear, size and ratings included, and send it with the street. For Islington, common sizes often travel from NW2, the call confirms yours, and an unusual one is collected on the way. The new tyre is fitted in your bay, balanced and torqued, then the other three are looked over so nothing else fails on Upper Street the same week. Tyre and callout are priced when you ring, and the figure does not move on arrival.
