OTR Tyre Repair Decision Tool
Should you repair
this tyre or replace it?
Answer the questions below about the damaged tyre. Get an immediate, technically grounded recommendation based on OTR repair standards.
What is the tyre construction?
Where is the injury on the tyre?
Select all that apply — a single incident can cause damage in more than one zone.
Select one or moreWhat type of injury is present?
Select the injury type for each affected zone. This determines whether repair is structurally safe.
What is the cord condition at the injury?
Inspect the prepared injury area. Cord condition is a primary factor in whether repair is structurally safe.
Is the sidewall injury above the A-B line?
The A-B non-repairable zone runs along the lower sidewall. Injuries below this line cannot be safely repaired regardless of size.
21.0–33.25" → 150 mm · 27.0–37.5" → 200 mm · 36.0–40.0" → 300 mm
Measured from the bead base to the injury point on the inside of the tyre.
What is the prepared injury size?
Enter the largest diameter of exposed body ply after preparation — not the surface cut size.
What is the tyre rim size?
Select the rim diameter from your tyre's sidewall marking.
Has this tyre been repaired before?
Previous repairs affect structural integrity, especially if overlapping with the current injury.
How much tread life remains?
Remaining tread depth affects whether repair is economically worthwhile — even when technically possible.
Has the tyre been run flat or significantly underinflated?
Run-flat operation causes internal sidewall damage that is often invisible from outside the tyre.
What is the operating environment?
