“…More recently however, Sarkissian et al. found that a low pyrolysis temperature of 450°C gave better discrimination between tire samples (6), even though pyrolysis of the vulcanized rubber sample is considered incomplete at this temperature.…”

Automobile tire marks can routinely be found at the scenes of crime, particularly hit-and-run accidents and are left on road surfaces because of sudden braking or the wheels spinning. The tire marks are left due to the friction between the tire rubber and the solid road surface, and do not always demonstrate the tire tread pattern. However, the tire mark will contain traces of the tire. In this study, Pyrolysis Gas Chromatography/Mass Spectrometry was used to analyze 12 tires from different manufacturer's and their traces collected after braking incidents. Tire marks were left on a conglomerate road surface with sudden braking. The samples were pyrolysed without removal of contaminant in a micro-furnace type pyrolyser. Quantitative and qualitative analysis were performed on all the samples. All 12 samples were distinguished from each other. Each of the tire traces were identified as coming from there original source.

“…A repeatability test, comparing conventional X-ray diffraction analyses with the technique of quantitative X-ray diffraction as a determinant of mineral abundance has been examined (369). Tires and tire traces have been analyzed by FT-IR and pyrolysis-GC/MS (370). Quantitative data have been reported on the amounts of iron that are transferred to the hands upon holding a firearm (371).…”

“…More specifically, the information for molecular discrimination tends to be from the volatile components, which can be lost from the increased temperature of tire trace creation event. 14 This issue can cause them to not directly match the molecular signal of the questioned piece of tire. Any molecular technique would be susceptible to this affect: thus, another type of chemical information can be provided to see differences between tires: the elemental profile of the tire.…”

Tire evidence is a form of trace evidence that is often overlooked in today's forensics, while frequently found at crime or accident scenes, usually in the form of skid marks. The pattern of the tire skid mark has been used before to link a tire or car to a scene, but the widespread use of anti-lock braking systems makes this an almost impossible and abandoned route of analysis. With this is mind, using the chemical profile of a tire has potential to link a car or tire back to a scene in which its trace material is found. This study shows the successful use of the elemental profile of tire rubber to classify thirty-two different samples by Laser-Induced Breakdown Spectroscopy (LIBS), analyzed by Principal Component Analysis (PCA) combined with Linear Discriminant Analysis (LDA). A classification accuracy close to 99% shows the ever-growing use of LIBS as a technique of choice for forensic analysis of tire rubber, opening the path for its use as a forensic evidence.
