▲Attention
A tyre choice must comply with the law and the recommendations of the vehicle or tyre manufacturer, or an official body (size, load index and speed rating, structure, etc.).
You need to take account of the conditions the tyre will be used in so that its performance levels meet hauliers' expectations.
If changes are made to an original vehicle component, you should check that the proposed solution complies with current legislation and the manufacturer's requirements and recommendations (See the regulations in force in the country). In some countries, the modified vehicle must receive an administrative approval.
Any tyre that is second-hand, used or has been involved in an accident must, prior to fitting, be checked carefully by a professional to ensure the safety of the user and compliance with current regulations (See best practice for tyre fitting and inflation).
Tyre misuse or an unsuitable tyre choice can also cause some mechanical parts to wear out prematurely.
▲Application:
STEP 1: Determine the right tyre size
The size must be approved by the vehicle manufacturer or tyre dealer and must at least meet the axle's maximum load capacity.
An axle's maximum load carrying capacity is set by the vehicle manufacturer in line with current regulations. Simply fitting this axle with tyres that can carry a larger load does not mean you can exceed the manufacturer's approved capacity.
Each tyre size corresponds to one or more suitable wheels, including in terms of rim width: see the ETRTO's "Standards Manual" and/or the vehicle manufacturer's recommendations.
Fitting a tyre on an unapproved wheel can cause: damage to the wheel and/or tyre, an unsatisfactory tyre-to-road footprint, and an abnormal tyre workload which can undermine the safety, behaviour, grip and service life of the tyre.
STEP 2: Choose the correct tyre
The MARLIN commercial vehicle tyre offer comprises eight tyre ranges designed and adapted to each business application and ready to help you optimise your operating costs.
To select the right tyre, we have to take into account the type of use and benefits of each range.
In addition, Marlin tyres also provide customers with three different product levels, BLUE, SILVER, GOLD, they are all cost-efficient in their class.
BLUE: Stable quality with reasonable performance.
SILVER: High quality with excellent performance.
GOLD: Used in some specific situation, such as extreme overloading, severe road conditions, etc. All GOLD tyres are "Reinforced".
STEP 3: Identify the right benefit
MARLIN tyres offer benefits depending on the operators specific needs.
STEP 4: Choose the right tread pattern
There are rules which HAVE TO BE followed when choosing the tread pattern of your tyres.
▲ OTHER RECOMMENDATIONS
· For tyres fitted on a steering axle, you must use tread patterns "F" or "A" only.
These tread patterns are designed and manufactured to cope with the specific stresses and strains imposed on the steering axles of motor vehicles: load capacity, slack with dynamic load transfer, scrubbing, axle geometry, high mileages, etc.
·For tyres fitted on a drive axle, you must use tread patterns "D" or "A" only.
"D" tread patterns are designed to cope with the specific stresses and strains imposed on drive axles: transmissions of engine and brake torque, twinning, the highest axle load of the whole road-going setup, etc.
Tyres with a "A" tread pattern can be fitted on drive axles, but given the stresses on this axle, you are likely to strike the best performance balance with "D" patterns. For some uses, "A" patterns also offer excellent performance when used on a drive axle: in an urban setting, for example.
·For tyres fitted on a trailer axle, you must use tread patterns "T" or "A" only.
These patterns are designed to cope with the specific stresses on trailer axles: static and dynamic loads, scrubbing, high mileages on centre axles, etc.Tyres with "T" tread patterns show load indices and speed ratings suited to towed vehicles (trailers or semi-trailers). When fitting tyres with "A" tread patterns, check that the load indices and speed ratings are suited to the needs of the axle.
