Use the calculator above — enter your tyre size and it returns the exact amount for one tyre.
-
Inject through the valve
Deflate the tyre, remove the valve core and inject the product through the valve stem.
-
Re-inflate and drive
Refit the core, inflate to the recommended pressure and drive a short distance so the product spreads around the tyre.

About this formula
This heavy-duty tyre sealant permanently seals multiple punctures up to 20mm in the tread area as you drive, preventing deflation and keeping vehicles moving in the toughest conditions. Engineered for extreme off-road environments, it’s ideal for mining tyres and other heavy machinery to stop you reaching for a puncture repair kit.
The versatile formula can be applied using a pump or poured directly from pails and drums, making it efficient for both field and workshop use.
Built to last the full lifespan of your tyre black, it prevents multiple punctures, reduces downtime, and can extend tyre life by up to 20%. Unlike many ordinary sealants, puncture repair glue or tyre gel, this sealant is safe for tyres and rims, this non-corrosive, non-hazardous glycol-based blend contains no flammable or toxic ingredients and stays stable in storage or in use. An essential sealant that prevents you reaching for a tyre puncture repair kit.
Questions
FOR WHICH TYRES CAN I USE OKO MINING?
OKO Original Mining can be used in any tubeless off road (OTR) tyre (tubes are weak and it is not possible to seal big punctures). It is most effective in tyres above 25 inches of wheel diameter. For the very largest, thickest tyres, of 50+ inches, where punctures are not common but tyre life is very short due to external damage, we recommend OKO LifeLong - it flows freely, cooling and conditioning tyres and protecting wheel rins from corrosion.
CAN I PUMP MY TYRE UP WITH THE SEALANT ALREADY IN IT?
Yes - the sealant forms a layer around the inner tyre tread. If any stray liquid has remained inside the valve, clear it with a stick so that the passage of air is not impeded. Always unscrew the valve core using a VCR (valve core remover) before applying OKO. Screw it back in after installation then reinflate the tyre to the recommended pressure.
Note that mining and large construction vehicles often have large-bore valves and an adapter will be needed when using the drum pump.
IS OKO COMPATIBLE WITH TPMS VEHICLES?
OKO Original Mining is not compatible with 'Direct' TPMS systems that use electronic sensor valves with narrow air passages. If the system uses sensors that are applied to the inner wheel rim, then the sealant can usually be applied.
DOES OKO WORK WITH MULTIPLE PUNCTURES?
Yes - only a small amount of OKO is used in sealing each puncture, leaving plenty for the other tyres.
HOW LONG CAN I DRIVE WITH A PUNCTURED TYRE?
For as long as the other tyres that have no punctures.
HOW LONG DOES IT LAST IN MY TYRE?
Whatever the lifespan of your tyres to date, expect OKO to extend it by at least 20%, even with no punctures. The sealant seals the tread, keeping the tyre cooler, more flexible, and at the right pressures.
IS OKO SAFE FOR ME AND MY ENVIRONMENT?
OKO Original Mining is classified 'Non-Hazardous' and is safe for transporting by air, sea or land. It carries ISO 9001 (Quality), ISO 14001 (Environmental) and ISO45001 (Health & Safety) certifications - no other sealant company has as many approvals.
HOW FAST DOES IT WORK AFTER APPLYING?
As soon as the tyre revolves, OKO is forced by the centrifugal force to cover the whole tread, and will work whenever the vehicle is moving.
HOW DO I USE IT?
Either apply the sealant through the valve using the adjustable OKO drum pump, which dispenses OKO against tyre pressure of up to 60psi/4.1 bar: or pour a measured amount of OKO into the open tubeless tyre after mounting one bead on the wheel rim; then mount the second bead and inflate the tyre. Always apply the sealant to new or fresh tyres, for lifelong protection and maximum effectiveness.
HOW DOES OUR SEALANT WORK?
A layer of liquid sealant coats the inner tyre surface. When a puncture happens, it is forced into the hole and forms a near-instant bond with the rubber, sealing the problem for the rest of the tyre's life.
