OKO ‘Mining’ X-tra Heavy Duty is for large tyres in the harshest locations of all, in mines, quarries, waste management sites and tough construction site conditions: it will seal 20mm+ holes and slits in big tyres.
Best used tubeless: but will function with inner tubes. Tested in Canada on a forestry truck with tyre temperature sensors, the OKO-treated tyres were 11.5% cooler inside than the matched non-OKO tyres. Coupled with the reduced porosity of the tyre treads, that adds up (across all user tests) to 20+% improvement in tyre life. The owner/driver even reported improved ride characteristics over the rough gravel tracks!
For most applications, replaces the need for solid fill: much cheaper, lighter and does not worsen the ride (quite the opposite, see above…)
Lasts the life of the tyre: will not dry out or separate unlike some others. Washes out after use.
