Gordon Brookes - Michelin Agriculture's Technical Manager
"We frequently see people using plug or string repairs to fill a hole as a long"term fix – not as temporary solutions these methods are intended for. String and plug repairs should only be used as a temporary solution to enable a vehicle that does not have a spare tyre to travel a short distance to a service provider for a professional repair.
"These types of temporary repairs allow air and moisture to infiltrate the structure of the tyre, so if used for more than a short period of time, they can cause irrevocable damage which can invalidate manufacturer warranties.
Neil Sharman - Technical & Field Support Manager for Trelleborg Wheel Systems
"Any external tyre repair that is carried out without removing the tyre must be a short term emergency repair only. The tyre should always be removed and examined for any internal damage before the correct repair is carried out by an authorised repairer. Non standard repairs will affect the tyres warranty".
