Please refer to each specific country legislation for tyre fitment and note that it can require mounting the same type of tyres on the same axle.
This means you can mount tyres with different tread patterns if they are:
The same brand,
The same size,
The same structure (radial or diagonal),
The same use category (road tyres, specialised, snow tyres with 3PMSF and M+S markings)
With the same load capacity indexes,
And the same speed rating.
However, for optimised tyre performance we recommend to mount tyres with the same tread pattern on the same axle.
If this is not possible, we advise to mount twinned tyres of the same type.
Respect the positions, fitting direction, direction of rotation and any relevant instructions when mentioned on the tyre sidewalls.
FITTING OF REGROOVED TYRES
The European Regulations No. 109 states:
1st case: UNIFORM FITMENT (RETREAD - RETREAD) ON THE AXLE
1. 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
5. tyre tread type
2. It is NOT ADVISED to mount retreaded tyres from different retreaders on the same axle, regardless of the brand of the casing.
3. It is AUTHORISED to mount retreaded tyres from the same retreaders, regardless of the brand of the carcass.
2nd case: MIXED FITMENT (NEW & RETREADED) ON THE SAME AXLE
We recommend to mix tyres on the same axle if:
1. The brand of the retreaded & new tyres is the same.
2. The brand of the casings is the same.
3. The following technical characteristics of the retreaded & new tyres on the same axle are identical:
1. Tyre sizes,
2. Structure (radial or
3. Speed and load
4. tread type (road, all-
terrain, 3PMSF &
Retreaded tyres are designed and manufactured to be used on drive axles and trailer axles.
We do not recommend the mounting of retreaded tyres on the front steer axle of the truck.
Please refer to each specific country legislation for retreaded tyres fitment on the same axle.
We recommend inspecting for:
Any uneven wear, holes, cuts, visible deformations to the tyre's shoulders, sidewalls or flange area
Any damage to the rim with a tyre professional.
Never put tyre units back on the road that show any damage, such as misshaped or exposed bead wire, detached rubber or plies, damage caused by grease or corrosive substances, mottling or abrasion of the interior rubber after any driving with under-inflated tyres. Tyres showing any of the above must be demounted, scrapped and processed as waste. Make sure the valve cap is in good condition at every vehicle inspection. In case of doubt, replace it.
Tyre rotation is an operation consisting of removing the tyre from one position on the vehicle and refitting it in another position.
Turning on the rim is an operation consisting of removing the tyre from the rim and refitting it the other way round.
Conditions for good tyre storage:
Clean, dry, temperate and well-ventilated premises, sheltered from direct sunlight and bad weather.
Well away from any chemical substance, solvent or hydrocarbon likely to alter the nature of the rubber.
Well away from any object which might penetrate the tyre (metal spike, wood, etc.).
Well away from any source of heat, flame, incandescent bodies, equipment which might give off sparks or electrical discharges and any source of ozone (transformers, electric motors, welding sets, etc.).
When storing in stacks, make sure that the tyres are not deformed. If they are to be stored for a long time, rotate the tyres (reverse the order of the tyres in the stacks), so as to be able to extract the oldest tyres first. Avoid compressing the tyres under other objects.
