Tyre regrooving, retreading and repairs

Correct regrooving, retreading and repair of commercial vehicle tyres makes sound economic and environmental sense, without compromising performance or safety. However, care must be taken throughout the process – beginning with thorough inspection to ensure tyres are suitable for reprocessing.

Regrooving commercial vehicle tyres

Regrooving of tyres should be carried out when the depth of the original tread has worn down to between 3mm and 4mm and in accordance with manufacturers' recommendations. It is legally acceptable and safe to regroove tyres for the following vehicles as long as the original tyres were suitable for regrooving:

  • Most commercial vehicles over 2½ tons unladen weight.
  • All electrically propelled goods vehicles.
  • All but the smallest trailers.

Only tyres in good condition can be regrooved. When a tyre shows signs of irregular wear, perhaps through incorrect wheel balancing or steering geometry problems, it should not be regrooved. Tructyre's fully trained specialist regrooving team carry out a thorough external inspection, checking tread depth at several places around the tyre before deciding if it's suitable for regrooving.

Tructyre has access to original manufacturers regroove tread patterns. This is vital, as it's illegal and potentially dangerous to recut a tyre to any tread pattern other than that shown in the manufacturer's regrooving manual.

After regrooving, we thoroughly check each tyre to ensure it remains free of any defects including cracks, separations or exposed ply or cord.

Retreading tyres

January 2005 saw the introduction of EC109 Standard for retreading introduced. The new standards require the compulsory testing of retreads and remoulds similar to standards set for new tyres. Our range of RE-TRAK Tyres and the other retreaded tyres fitted by Tructyre meet or exceed this stringent standard.

Repairing Tyres and checking for tyre damage

There is a strict British Standard for tyre repairs (BS AU159), which means any repairs must be carried out by a professional operator such as your Tructyre technician. When a tyre is punctured or damaged in any way it must be carefully examined internally as well as externally to make sure there are no hidden faults.

Use of simple externally applied plugs and sealants are not a safe method for repairing a tyre. Tructyre will not use these or similar techniques. Further, no tyre manufacturers condone such repairs or accept responsibility for problems arising from them.
