Tire wear is a technical, economic, safety, and environmental problem that becomes more complex when vehicles are operated in regions where summer heat, winter moisture, dust, rough pavement, and frequent start stop traffic occur together. The aim of this manuscript is to examine how climate and road operating conditions influence the wear of passenger car tires and to develop an applied framework that can be used in a graduation project devoted to the analysis of tire deterioration. The study combines a literature based interpretation of tire road interaction with an analytical monitoring scheme based on tread depth reduction, estimated mass loss, road temperature, pavement roughness, vehicle load, tire pressure, and route type. The proposed approach treats tire wear as the result of contact stress, thermal softening of tread rubber, road texture aggressiveness, water lubrication, slip, and driving dynamics rather than as a function of mileage alone. The results show that the same mileage can produce substantially different tread loss when road temperature, surface roughness, tire pressure, and maneuver intensity change. The analytical scenario indicates that hot dry urban operation can increase annual tread depth loss compared with moderate motorway operation, while underinflation and rough asphalt amplify the effect. The paper concludes that climate and road condition monitoring should be included in tire service planning, especially in hot continental regions where pavement temperature can be much higher than ambient air temperature.
