While all tires require care those who are mounted on classic cars they need some specific considerations to ensure better performance and duration. Michelin , which has a large number of products adapted to each era, gives us safety and use advice for the correct care of these covers.

VALVES: In the first instance ensure that the valve is in good condition and it is recommended to respect the instructions for use provided by the manufacturers regarding fit and compatibility with the rim, among others. In addition, it is advisable to systematically tighten the valve cover and ensure the protection of the mechanism, the total tightness of the pneumatic assembly, as well as regularly checking the tightness of the screwed valves.

Michelin Classic CarsASSEMBLY AND DISASSEMBLY: At this stage it is necessary ensure proper mounting devices and for that it is always advisable to refer to the manufacturer's manual to identify the correct use. Additionally, the direction of rotation must be respected for directional tires and the mounting side for asymmetric tires. In the case of the TT mount (with inner tube), the dimension of the inner tube must correspond to that of the tire (section and diameter) and the rim to receive the inner tube without damaging it.

INFLATED: It is necessary to remove the inside of the valve and verify that the beads are correctly centered in relation to the rim flange. In the case that they are badly centered, it is necessary to deflate and repeat the operation completely, including lubrication. Inflation must continue to 50 psi to obtain proper bead placement, and if higher pressures are required, a protective cage must be used when inflating the tire. Once the inflation has been carried out, the inside of the valve must be placed, adjusted to the operating pressure and, finally, the cap screwed on to ensure complete tightness.

Michelin Classic CarsAt this stage it is only necessary to use inflation systems provided for this purpose and not to remain in the vicinity of the pneumatic assembly. Therefore, it is essential to ensure that the compressed air hose attached to the valve has a safety clip and that it is long enough to be able to stay clear of possible projections in the event of an incident.

MONITORING AND MAINTENANCE: It is important check tire pressure before every trip and correct it, If that's the case. The pressure must be checked cold, that is, when the tire did not roll. In the event of an unusual pressure drop, check the internal and external condition of the tire, as well as the condition of the rim and valve. Any visible drilling, cutting or deformation should be subject to a thorough examination by a professional.

One point to keep in mind is that nitrogen inflation does not dispense with periodic tire pressure checks. Another common check is balancing, which must be done on all four wheels and which, additionally, must be calibrated according to the manufacturer's manual.

Michelin Classic CarsREDUCED TIRES: The redrawing changes the characteristics and performance of the tire that is why it is prohibited for use on public roads. This operation requires appropriate equipment and tools and compliance with the instructions for such a procedure. On the other hand, tires must be designed for this purpose, and in the case of cars and trucks, they do not allow it.

STORAGE: When it comes to conserving them, the place has to be dry, ventilated, without direct light and reserved for tires. Racks should be used to store them vertically to avoid stresses on the structure. To preserve the characteristics and properties of the covers, certain important points must be taken into account such as avoiding direct and prolonged exposure to the sun or sources of high heat and / or humidity, long-term storage in racks, presence of solvents, lubricants, fuels and other chemicals. In addition, you should stay away from devices that cause ozone release such as transformers, welding machines, electric motors, etc.

TIRE AGING: It is vital to watch for signs such as cracks in the tread rubber, shoulder, lower sidewall, or deformation. Faced with this, the tires should be removed and, in case of doubt, contact a professional.

Michelin Classic CarsAssembly and disassembly, inflation and balancing must be done by trained personnel, suitable equipment and in good condition.. This guarantees compliance with legal regulations and correct procedures, and respect for both the position of the tire on the vehicle (left, right, front, rear) and the operating pressure. Measuring devices such as the pressure gauge must be calibrated and verified at least once a year, either by an authorized organization, the supplier or the manufacturer.

Following the conditions of use, Michelin recommends never chemically intervene on the external rubber of the tire, or use tires whose past is unknown. It must be ensured that the pressure, alignment, speed and axle load values ​​are recommended according to the intended use. Failure to follow these instructions or procedures can lead to improper assembly and premature wear.

Finally, it should be noted that, as with any type of vehicle, the choice of tire must be in accordance with the equipment of the car (defined by the manufacturer), ensuring that all tires mounted on the same axle are of the same type (brand, trade name or industrial reference, dimension, structure), in addition to the type and diameter of the rim corresponding to the type of tire . Also, the tire should be checked to see that it is in good condition and it does not show any deterioration (crack, deformation) and that the tires have not been repaired (otherwise, they must be replaced).

Whether it is a car from the 30s or the 80s, following these kinds of considerations is essential as it will guarantee fans of these vehicles a not only pleasant but above all safe driving.
