Tire Road and Wear Particles are a major source of microplastic emissions. Tire and Road Wear Particles are important to study and understand as there are alarming amounts found in various environments. Currently, Tire and Road Wear Particles compared to other microplastics are not studied as rigorously in literature but are becoming a larger field of study due to their impact on emissions control. Tire Road and Wear Particles are commonly found as Styrene Butadiene Rubber Butadiene Rubber, and Natural Rubber To understand and quantify tire wear, experimental and mathematical models are developed to estimate tire wear. Tire wear can be measured experimentally using semi-empirical models, predetermined data, and sensor technologies. Tire wear is also measured mathematically using different modeling approaches and different friction models. This review discusses different and popular methodologies for estimating tire wear through experimental and simulated environments. Furthermore, discusses a review of the literature regarding tire wear emissions and its impact on the environment. Finally, it is evident that an accurate simulated tire wear model can be developed in the future alongside a driver model to predict tire wear emissions.

What the full text shows
Shown in the lab- Global tire wear emissions are estimated at a specific annual tonnage. — 5,917,518 t/a (Global estimate for 2020)
- Tire wear emissions per capita in Europe. — 2.6 kg/capita per year (Europe, 2020 estimate)
- Peak wear rate for truck tires in the middle path under increasing inflation pressures. — 30.1 mg/km (Tires sliding across asphalt pulled by a tractor)
- Peak wear width for aircraft tire tread blocks at lower draft angles. — 5.5 mm (Normal loading mechanism on concrete and asphalt terrain)
- Tire wear particles contribute to a significant portion of microplastic emissions in some countries. — over 50% (Specific unnamed countries)
- Setup
- Review of multiple studies including the LAT100 abrasion tester, truck tire rivet tests, and aircraft tire block-level analysis.
- How
- The paper is a technical review of existing literature. It analyzes experimental methods (sensor data, abrasion machines like LAT100, rivet-embedding) and mathematical modeling for estimating tire wear.
- Limitations
- Experimental datasets often cover a very finite range of operating conditions. · Some lab tests use non-inflated tire samples, omitting pneumatic damping characteristics. · Current simulated models are simple and developed under limited conditions. · Difficulty in discerning exact origins of particulates in environmental samples.
