The invention relates to a tyre tread structure for experiments, in particular to a pneumatic tyre tread with pre-abrasion tool grooves. The pneumatic tyre tread with the pre-abrasion tool grooves structurally comprises a tyre tread body. At least two tread grooves are formed in the tyre tread body in the circumferential direction. Circumferential belts are formed on the tyre tread body and located between the tread grooves. The circumferential belts are provided with pre-abrasion block bodies. The pre-abrasion block bodies are formed through division of the tool grooves which are distributed in the circumferential direction of the tyre tread body. The pre-abrasion block bodies are evenly distributed on the circumferential belts. The widths of the tool grooves are not larger than 5 mm. The angle formed between each tool groove and the transverse direction of the tyre tread body is 0-90 degrees. According to the pneumatic tyre tread with the pre-abrasion tool grooves, pre-abrasion of the pneumatic tyre tread serving as an experiment target is standardized, so that the pneumatic tyre tread has the unified pre-abrasion state, in this way, an experiment result is made more accurate, and all properties of the stable state of a tyre during normal traveling can be represented in time.
