Regrooving tyres – what you need to know?
Tyre tread regrooving is a process that begins with removing the rubber from underneath the tread. This means, you can deepen the depth of grooves that was affected by the tyre’s mileage.
A very important thing – only the tyres that were designed for regrooval can undergo the process. How to recognize if a given tyre can be regrooved? This is the most certain way:
check if the tyre has the REGROOVABLE label on the sidewall
A tyre has to be specially designed for regrooving. The tyre’s carcass has to be strong enough to withstand the modifications and be able to stay stiff even at larger speeds. A specially designed carcass means better stability of tyre’s profile while driving.
What is tyre regrooving about?
This is a process that allows to restore the tread’s original shape and depth. Tyre regrooving can restore the tread from 6 up to 8 mm.
It begins with removing the 2-4 mm of rubber underneath the tread. The acceptable depth of the cut is shown in the manufacturers’ recommendations. The regrooving should be done when the tyre’s tread depth reaches 2-4 mm. At that moment, it is still relatively easy to restore the original shape of the tyre’s tread.
What happens after the regrooving? You get a tread with improved driving qualities.
Tread regrooving benefits
Tyre regrooving comes with a range of advantages. Check them out:
Improved traction – up to 10%
Fuel savings – up to 2 L per every 100 km
Extended mileage – a tyre that underwent regrooving can be used for 25% more kilometers.
When is regrooving not recommended?
Avoid regrooving in the following cases:
there are cuts on the tyre
there are visible rubber losses
tread is cut or blown
belt edge cushion comes out of the tyre
casing comes out of the tyre
the sidewall is damaged
Why is that so important? Any damages in tread’s surface may let the air or water inside the tyre. As a result, a tyre like that would wear out quickly. And if you did a regrooving process here, riding on a tyre like that could get dangerous.
The above recommendations were prepared on the basis of tyre manufacturers’ recommendations.
And one more thing. Tread regrooving must not be done on tyres which are not prepared for this – for instance, on passenger car tyres.
