The roles of tyres is pretty obvious—to provide a firm grip, maintains connection between the road and vehicle; and most importantly to prevent the vehicle from “slipping” and causing accidents.
Of course, brand new tyres perform more efficiently without any hitches though as the tyre and vehicle become hoary, the level of efficiency decreases due to wear and tear.
The friction between the tyre and road causes the tyres’ components known as threads to wear out hence leading to loss in grip upon the road. Thankfully, with tyre retreading, you don’t have to dig deeper in your pockets each time these threads fray.
This comprehensive guide by 3G Tyres therefore takes you through the entire process of tyre treading and hopefully at the end of it, you’ll be well-informed to decide whether to retread or buy new tyres.
Over the years, the tyre manufacturing industry has greatly invested in state-of-the-art technologies which help to deliver high standard tyres that perform exceptionally not only during their ‘first life’ but also in their second and third stages of life.
In the same way, tyre retreading is growing in great leaps as more powerful tyre casings, high quality rubber compounds and improved re-manufacturing approaches are employed to produce flawless products that are as good as new.
The Tyre Retread Process
The process of tyre retreading features two main techniques: pre-cure and mold cure. The mold curing technique also has two processes which begin with:
Assessment of the damaged tyre to ensure it’s in a usable condition.
Ideally, tyres whose tread or cords are totally worn out cannot pass on to the next stage. The inspection process involves identifying the embedded fragments and invisible damage before buffing it to remove the remaining tread. Tyres whose casings are still in good condition can be taken through the tyre retread process severally.
During inspection, 3G Tyres go through an additional test known as Laser Digital Shearography where the laser scans the whole tyre as the mechanic tries to check for any damages at the most intricate spots. This determines whether retreading is possible or not.
This is the second phase after inspection and selection of tyres to be retreaded. Here, certain portions of the tyre are cut or taken out to remove unwanted elements and enhance the flexibility of the tread.
This way, the mechanic removes any block of tread that may have formed on the tyres which provide a coating over the part between the rubber and the tread’s grooves. This process is executed by computerized machines operated by our highly professional mechanics.
This phase involves establishing the real cause of damage to the tyres and repairing the damage once and for all. Nothing is left to chance and even the small holes in the tyres are identified through a process that allows high voltage electricity to pass through the tyre. This enables the tyre to regain its vigor.
Here, materials are put into the casing via computerized equipments to enhance the tyre’s natural properties.
Computers are used in this process so as to avoid possible errors caused to the system and to ultimately enhance the efficiency of the tyre. With advanced technology, computers have become highly accurate and are quickly replacing the cumbersome error-prone manual tasks day by day.
At this phase, the tyre is subjected to heat before the level of the tyre is once again checked. This process helps to determine the quality of the rubber used and confirm whether or not it’s vulnerable.
This is the final step that involves finding out if the tyre is set to hit the road. This step features several inspections carried out to ensure the tyre has no imperfections whatsoever. Here, the tyre is taken through two tests i.e. the tactile and visual inspection and inflation tests. After all these tests are completed, the tyre is taken through a Shearography which removes any traces of errors that could be identified.
Pros of Tire Retreading
Ask any owner of a fleet and they will tell you maintaining a fleet of vehicles can cost you an arm and a leg before finally hammering your bottom line. Thankfully, tyre retreading comes in handy to save money as retreaded tyres cost significantly less than the brand new ones yet they perform the same or even better than new tyres.
The process of retreading tyres is easier on the environment compared to that of dumping old tyres in landfills. Hence when it comes to environmental conservation, the benefits of retreading are numerous including ability to reduce harmful carbon gases released into the atmosphere.
Variety of Designs
With hi-tech technology, retreaded tyres come in various designs and hence you can get a customized design that fulfills your desires.
Cons of Tyre Retreading
The entire process of retreading must be done by highly skilled professionals that strictly adhere to set standards otherwise any laxity and improper inspection may ultimately compromise the driver’s safety.
Generally, retreaded tyres are technically reused tyres and hence may not be relied upon again and again, and besides poorly retreaded tyres may cause tramlining.
Finally, tyre retreading is certainly a process that breathes a new lease of life into your old and weary tyres. And with this guide, will you retread or buy? Share your thoughts with 3G Tyres at
