IRD’s TACS screens vehicles for unsafe tyres

IRD’s Tire Anomaly and Classification System (TACS) is an innovative technology that identifies potentially dangerous tyre anomalies before accidents occur. Tyre anomalies are conditions such as underinflated, flat, missing or mismatched tyres. These tyre problems can result in vehicle imbalance, reduced maneuverability, improper load distribution, reduced braking performance, poor fuel economy, and reduced tyre life. Pavement damage can also result from increased loads on tyres when adjacent tyres are flat or mismatched in size.

Agencies responsible for commercial vehicle inspection and enforcement have implemented TACS to carry out pre-screening for tyre problems in advance of inspection stations. In this application, TACS is used similarly to weigh-in-motion (WIM) to identify vehicles with safety issues and flag them for enforcement, while allowing safe vehicles to bypass inspection. These agencies have found TACS to be an effective solution for identifying vehicles with tyre problems that are sufficiently serious to place unsafe vehicles out of service. TACS may be integrated into existing weigh station management software so that inspectors can see exactly which tyres to examine.

Industry is also interested in tyre safety screening. Damaged tyres lead to breakdowns, expensive roadside repairs and increased costs due to freight delays. TACS is capable of screening at highway speeds, so it is well suited to use in scenarios where the drivers of commercial vehicles are alerted when tyre problems are identified. IRD has supplied TACS for a number of systems that use message signs to warn drivers of underinflated tyres that could pose a safety risk.
