Abstract
This paper investigates the effect of various tread design parameters on tyre-terrain interaction characteristics. The off-road terrain chosen for this study is varied moisture content sand. The sand terrain was modelled and designed using the smoothed-particle hydrodynamics (SPH) technique, calibrated using measured terrain data. The truck tyre used in this research is a 315/80R22.5 tyre, designed and validated through finite element analysis (FEA). The tread of the 3-groove base model tyre is modified with 4-grooves, 5-grooves, half depth, and quarter depth to study the impact of the number of grooves and tread depth on the tyre-terrain interaction characteristics. To study this impact, variations of tyre loading and tyre speed were simulated over different terrains. The tyre-terrain interaction characteristics studied include rolling friction, tyre vertical displacement, and longitudinal slip.

Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
