The rubber circumference of a tyre that comes into contact with the ground or road is known as a tyre tread or track. Furthermore, the term "tyre treads" is casually used to refer to the grooves that are molded into the rubber of tyres in various patterns. Technically, these grooves are known as the "tread pattern" of a tyre. Simply put, grooves aren't the tread, they are simply located in it.

The primary purpose of "tyre treads" or grooves is to provide traction. Worn-out tyres fail to provide safe levels of traction for vehicles since their treads or technically speaking, grooves don't have enough depth. Such tyres need to be either retreaded or replaced for the proper functioning of vehicles and the safety of passengers.

The grooves located on the tread of tyres, casually referred to as tire treads create traction between the tyre and the surface it's in contact with. Tyre treads control traction by determining the ratio between rubber and air space between the tyre and the road surface. Furthermore, they affect the level of noise generated by tyres.

Just as different vehicles are used for different purposes, different tyre treads or grooves are used to achieve different performance goals. They are used to optimize the cornering ability of vehicles, improve acceleration, the reliability of braking, and enhance fuel economy of vehicles.

When a tyre sustains some wear but still has enough rubber on it to be safe for driving, retreading or regrooving tyres can prolong its lifespan and delay the need for a replacement. Retreading tyres, therefore, provide a highly economical and environmentally-friendly option for vehicle owners. Different retreading methods exist. Some retreading methods completely revamp tyres by replacing the worn-out tread with a renewed tread as well as the sidewall rubber while others simply focus on sharpening grooves and groove patterns.

There are many myths surrounding the safety of regrooving tyres and most of them are outdated. Tyre retreading technology has taken massive strides over the last few decades where millions of vehicles around the world, even some school bus fleets running on retreaded tires. Retreaded tyres are usually safe for use provided that they are structurally sound for retreading and the tyres are originally manufactured using high-quality rubber compounds.

When it comes to regrooving tyres with the Tread Doctor tyre groover, you simply need to ensure that there is enough rubber left on the knob tyres for trimming and grooving. Generally, a tyre can be safely trimmed or carved using Tread Doctor Knobby Cutting Tool up to three times.
