OKO was tested over a 6 week period on their ‘worst construction site’ in the U.K. for the recorded incidence of punctures. They were reduced by 95%. “Eventually, we should like to see Manufacturers putting OKO into the tyres of their vehicles as Original Equipment” -Plant & Transport Manager

“OKO quickly plugs holes with little loss of air, and maintains its effectiveness over a long period. I once counted over 180 thorns in one front tyre after working for 6 months, but apart from maintaining the air pressure occasionally, we have had no downtime caused by punctures”.

An OKO seal “strength test” has been conducted by The Gerotek Test Facility at Pretoria, owned by ARMSCOR, the officially-appointed acquisition organization for the South African department of defence.
Tests demonstrated that the necessary strength of pressure applied to penetrate the OKO seal was 1.6 times more than that applied to penetrate the traditional vulcanized repair adopted by the tyre industry. The pressure applied was 7.4 times more than the repair plug used by tyre companies. By far, the strongest seal was that made by OKO.

Raleigh tested OKO, and made several holes in a tyre 28” x 1.5”.
Finding: “The manufacturers claim that OKO will seal holes in the tyre contact area caused by puncturing objects up to 3 mm in diameter. The tests conducted appear to substantiate the claims made by the manufacturers of OKO Tyre Sealant”.

Tests were carried out on Mopeds and Motorbikes, covering 276,250 miles in a long period (> 1 year). This included Motorcycles - 211,250; Mopeds 65,000. Of the total miles - 92,500 miles were ridden in bikes WITHOUT OKO and tyre flats were experienced during this period. In ALL these puncture cases, steering became ungovernable. In two cases it resulted in serious injury. Of the total miles - 183,750 were ridden WITH OKO. During this period, the Mopeds had 5 punctures and the Motorcycles 10 punctures, all of which were successfully sealed by OKO. In all these cases, the bike remained in control even when a very large hole resulted in some air loss. Finding: “From our experience the use of a preventative tyre sealant such as OKO may be valuable with regards to greater safety and ease for users of two wheeled transport. Not all punctures are prevented or “cured” by the use of these products, but any punctures that do occur become evident in a much safer way. Punctures caused by objects that are not subsequently retained in the tyre, can largely be prevented. Our experience has not shown any disadvantages in the introduction of a preventative based tyre sealant. Data from other test reports do not contradict our findings”.

OKO was used by the winning vehicle and others in the top 5 in the incredibly gruelling ‘Roof of Africa’ cross-country race, enduring rocks and boulders taken at speed: and enormous temperature variations.

A leading French Quad Bike racing team tested OKO for Quads and achieved 4 out of the 5 top positions in the race. Other competitors dropped out due to punctures.

OKO XT for Motocross and Enduro was recently trialled by a major specialist tyre manufacturer and saw off the competition from another manufacturer. Used in races it won several times and in destruction testing it sealed slits as well as holes, up to 9mm.

‘Live and Let Chai’ was the team of Owen Terry and Aiden Rigby who took part for charity in the 2011 Rickshaw Run, from Jaisalmer in northern India to Cochin in the South, The Rickshaw Run is pretty simple. With no preparation and less luggage you fly to the Indian Subcontinent and do your damndest to force a ‘150cc glorified lawnmower’ over thousands of miles of questionable terrain in around two weeks with no support at all. But our heroes had OKO in their tyres: and despite enduring what their blog described as ‘potholes the size of houses’ they did not suffer a single puncture and despite running into a truck en route they were able to finish the course having traversed the sub-continent from north to south.
