FITTING RETREAD TYRES
Retreading tyres makes the casing of a tyre more valuable by giving it a new lease of life. This ecological and economical practice increases a casings milage in compliance with legislation (European standard ECE 109) and safety standards defined by manufacturers. It's one of the key elements of the tyre life cycle.
BF Goodrich advises that the difference between the depths of the main grooves on a dual fitment or on a drive axle fitted with dual or single tyres must not exceed 5mm at the same phase of life (regrooved/non regrooved). This advice does not apply to non-driven axles fitted with single tyres, although the legal requirement of the country of operation must be taken into consideration.
EXAMPLE OF A UNIFORM FITMENT (RETREAD-RETREAD) ON THE AXLE
BF Goodrich recommends that the technical characteristics of the retreaded tyres fitted to a vehicle must be the same:
1. Retread brand
2. Tyre size
3. Tyre structure
4. Speed rating and tyre load indexes
5. Tyre tread type
It is NOT ADVISED to mount retreaded tyres from different retreaders on the same axle, regardless of the casing brand.
It is ADVISED to mount retreaded tyres from the same retreader, regardless of the casing brand.
EXAMPLE OF A MIXED FITMENT (NEW & RETREADED) ON THE AXLE
BF Goodrich recommends that its tyres should only be mixed on the same axle if:
- The retreaded and new tyres are from the same brand.
- The make of the casing is the same on new and retreaded tyres.
- The following technical characteristics of the retreaded and new tyres on the same axle are identical:
- Tyre dimensions
- Structure (radial or diagonal)
- Speed and load indicies
- Tread type (road, all-terrain, 3PMSF & M+S marking).
We do not recommend fitting retreaded tyres on the front steer axle of motor vehicles. As an example, It is therefore possible to use a retreaded tyre on a second axle of a 8x4 truck or a tag axle.
