A test matrix of five load levels and six inflation pressures was used on both HVS test tyres at creep speed conditions (<6km/hr). Using the local Stress-In-Motion (SIM) technology, the measurements were done using a specially constructed concrete test facility at Gautrans Koedoespoort premises. The aim of this study was to quantify the three-dimensional tyre-road pavement contact stresses for these two types of truck tyres, which is currently employed for accelerated pavement testing (APT) in South Africa. The two test tyres used on the HVS are a dual set of 12R22.5 and a single 315/80 R22.5 radial tyres, which represents typical tyres used on heavy vehicles (HV) in South Africa. “fingerprinting”) of tyre loading and contact stress patterns associated with slow moving test tyres on the new Heavy Vehicle Simulator (HVS Mk IV+) of Gautrans. This paper addresses the measurement (i.e.
