How does it Work?
OKO is injected into the tubeless tyre, or into the inner tube, via the valve stem BEFORE a puncture occurs. OKO remains liquid inside the tyre, giving protection against punctures that may occur in the tread area. When a puncture happens, air pressure forces OKO into the hole whilst the tyre is moving and OKO immediately forms a strong airtight seal that STOPS any tyre deflation. OKO seals the hole as you drive. The OKO seal in the tread area of the tyre is Permanent. The OKO seal is much stronger than the traditional puncture repairs.
Naturally we recommend OKO be fitted to new or nearly new tyres to get the maximum benefit.

Frequently Asked Questions
Can OKO be installed in any tyre?
There are grades of OKO for any pneumatic tyre (we do not sell OKO for preventative use in cars).
Does OKO affect tyre life or the performance?
Performance – No. OKO does not affect tyre structures or rubber. In most cases tyre life is extended as OKO keeps air inside, and cools, the tyre. OKO also increases tyre life by sealing punctures and avoiding run-flat damage.

OKO On Road products have been tested at various speeds in a variety of vehicles, including motorbike tests on race tracks. OKO On Road sealants are designed for use on the highway to a maximum of 80 mph/ 130 km/h or any lower legal speed set by the authorities. DO NOT EXCEED YOUR LEGAL VEHICLE SPEED LIMIT.
What type of damage can OKO seal and repair?
It will seal holes in the tread area caused by nails, screws, glass, stones and sharp objects.
Is the amount of OKO applied to any particular tyre size critical?
Yes. The amounts to be applied for any given tyre size are shown on the labels; the Dosage Calculator on our website; and the OKO application charts.
Why are there different types of OKO? Should I take care in choosing one?
The OKO Group makes several different formulations. These are designed and engineered especially for certain vehicle types. You can choose the right grade of OKO via our website or by examining the product description on the labels of the different bottles anddrums. Only use the correct grade.
