Sažetak
The paper presents a research of the
characteristics of the personal vehicle tires from
the point of view of the issues of driving safety
and environmental protection.
Changing the cornering stiffness of the
pneumatics and changing the depth of the tire may
cause vehicles to drift. If we replace tires with
better tires only on the front axle, the vehicle will
behave insecurely in driving. Using the individual
wheel brakes, a vehicle stability control equation
is set. Driving safety is also associated with
the emergence of aquaplaning on wet roads. In
order to assess the condition of urban vehicles,
we conducted an empirical research on the depth
of the tire canal, and provided an analysis and
conclusions on driving safety. Fuel consumption
tests warn of the importance of constant pressure
monitoring of tires. The wheel homologation is
linked to the engine and transmissions, ie fuel
consumption and exhaust emissions. Laboratory
and real-time testing determines fuel consumption
and exhaust emissions. We can conclude that
the modern wheel is conditioned by the driving
safety from vehicle drift as well as environmental
protection
