The tread of a tire or track refers to the rubber on its circumference that makes contact with the road or the ground. As tires are used, the tread is worn off, limiting its effectiveness in providing traction. A worn tire can often be retreaded.

Precure retreading involves vulcanisation without a mould at a high temperatures . The tyre is retreaded using a pre-vulcanised new tread liner. The process is called Precured retreading. In this process, bonding of Precured Tread liner and worn out tyres takes place in a tyre chamber under pressure and temperature. Tyres from Light Commercial Vehicle, Bus, Heavy Truck, Tractor to OTR tyres can be retreaded.

Bonding gum is a thin film or layer of rubber compound which is used in tyre retreading to bond the worn out tyre and tread rubber/ precured tread liner. It bonds the tread liner and the worn out tyres under pressure and temperature.

Crumb rubber is a term usually applied to recycled rubber from automotive and truck scrap tires. During the recycling process steel and fluff is removed leaving tire rubber with a granular consistency
