There are many situations in which steel reinforcement within structural materials is vulnerable to corrosion. In some cases the result of such deterioration of the structural integrity can have significant safety implications. However, there is currently little by way of reliable non-destructive means of obtaining direct evaluation of the state of the embedded steel, which yields anything more than rudimentary information. This paper considers the possibilities of making use of the vectorial nature of the magnetization of steel to improve the qualitative and quantitative evaluation of the integrity of embedded steel reinforcement in vehicle tyres. Results are presented which show that enhanced non-destructive mapping of faults within tyres can be achieved by this means.
