Michelin recommends mounting tyres with the same tread pattern on the same axle. If this is not possible, Michelin advises mounting dual tyres of the same type.
Fitting tyres with different tread patterns is allowed provided they have:
Reminder: for technical reasons, we recommend not mounting tyres with a deviation of more than 10 mm in diameter on the same axle.
Possible mounting for regrooved truck tyres
Please refer to the regulations of each country for specific adaptation.
Michelin retreaded tyres (MICHELIN Remix and LAURENT Retread) are designed and manufactured to be used on drive axles and trailer axles.
We do not recommend mounting retreaded tyres on the front steer axle of motor vehicles; including tread Z.
It is possible to mount retreaded tyres on the second front axle of a 8 x 4 truck.
The characteristics of retreaded tyres which must be the same are:
Retreaded tyres from different manufacturers MUST NOT be mounted on the same axle, regardless of the make of the casing.
Retreaded tyres from the same manufacturer MAY BE mounted, regardless of the make of the casing.
Diagram of authorised axles with permitted uniform retread mounting:
Reminder: for technical reasons, we recommend not mounting tyres with a deviation of more than 10 mm in diameter on the same axle.
The difference between the depths of the main grooves on two tyres fitted on the same axle must not exceed 5 mm.
1st example: maximum difference
on the axle: 4 mm = GOOD
2nd example: maximum difference
on the axle: 6 mm = OUTSIDE OF RATING
When fitting on a steering axle you must:
Use exclusively “F” or “Z” tread patterns.
These tread patterns have been designed and manufactured to meet the specific rolling demands of steering axles of motor vehicles: load capacity, hanging with dynamic load transfer, slipping, geometry angles of the axles, high mileage, performance etc.
“F” or “Z” tread patterns may have markings on the sidewall indicating that they rotate in both directions. This is intended to optimise tyre performance.
Note: Once the tyre is 50% worn, the tyre can be rotated in order to obtain more even tread wear.
We do not recommend mounting retreaded tyres on the front steer axle of motor vehicles; including tread Z.
When fitting on a drive axle you must:
Use exclusively “D” or “Z” tread patterns. “D” tread patterns are designed to meet the specific demands of drive axles: transmission of engine and braking torques, twin fitment, greatest axle load of all, etc.
Tyres with a “Z” tread pattern can be fitted on drive axles but the compromise in performance to meet the demands of this axle will be optimally met with the “D” tread pattern.
In some instances, the “Z” tread patterns are also optimised for use on a drive axle: urban usage for example.
