UNEVEN TIRE WEAR
Uneven wear in the tread area (in the center of the tire, on the shoulders or at the connection points) is often a sign of a mechanical problem. The cause could be wheel alignment, balance, shock absorbers or drivetrain, have your mechanic or tire supplier check it.
DEGREE AND FORM OF WEAR
Like all parts of a car, the tire also wears out. This happens all the time and not just in improper operating conditions.
Tire wear is caused almost entirely by contact surface friction during travel and the forces associated with it, such as traction, braking and steering torque.
You'd better check it out wheel alignment and tire balancing every six (6) months, this helps prevent uneven wear, extends the life of your tires and ensures safer vehicle handling.
It is important to always check the tread in various random places. Use a tread depth gauge (hand tool available at any auto parts store) or look to find the wear indicator on each tire, if the tread is at the level of the wear indicator replace your tires as soon as possible. The deeper the tire grooves, the better. The minimum depth is 1.6mm around the entire rolling circumference.
THE maintaining the correct pressure during operation guarantees safety and economy.
This is the result of a series of tests carried out by vehicle manufacturers and represents the best combination of performance and lifetime. The correct value is stated, for various conditions of use, in the Vehicle Manual.
It is a good idea to check/correct the pressures at least once a month, not forgetting to check the pressure of the spare tire. In this case it is necessary to check if there is a valve cap, which must be tightened by hand.
A low pressure recognized by the problematic behavior of the vehicle while driving and overheating of the tire endangers our safety.
A high pressure drastically reduces passenger comfort and makes the tire more vulnerable to collisions that cause damage to its sidewalls
The appearance of bulges on the sidewall is the unmistakable sign of irreparable damage to the tire frame.
This damage is usually caused by accidental bumps on curbs, rough road objects and potholes, but is also produced by too low pressure, due to excessive load and sometimes by rigid vehicle wheel alignment.
We must emphasize that the use of low or very low profile tires requires greater care during the use and maintenance of the tires, in the sense that the lower the profile the greater the sensitivity to the situations we mentioned above.
USE OF SNOW CHAINS
Using snow chains on snow-free roads can irreparably damage the tires. Therefore, it is recommended to remove them as soon as the road surface is clear of snow, and for one more reason: To prevent the chains from removing pieces of rubber from the tread, completely destroying the tire.
REGULAR CHECKS ON THE GEOMETRIC ANGLES
Minor collisions, possibly due to parking manoeuvres, raising/lowering pavements, crossing tram lines, rough road conditions and potholes are 'injuries' that can change the vehicle's geometric alignment.
It is recommended to regularly check the geometric angles (mainly wheel alignment, camber angle and distances) so that the behavior of the vehicle is not compromised. Consumption optimization is also achieved, safety and economy are improved.
USE OF EMERGENCY RESERVE
To reduce weight, more and more vehicles use the so-called emergency reserve instead of the normal one.
The marking “temporary use” means that the wheel can only be used to get to the nearest 'service' point to replace and fit the standard tire on the vehicle.
– The maximum permitted speed is 80 km/h regardless of the speed index of the other tires fitted to the vehicle.
– Like standard tires, it can be used until the tread depth reaches 1.6 mm.
– It is forbidden to use the vehicle with two or more temporary reserves at the same time.
Consult the vehicle manual for operating pressure.
