On-Road RTG


OKO On-Road RTG (Road Transportation Grade) is a unique concentrated tyre sealant for commercial On-Road tubeless tyres of HGV (Heavy Goods Vehicles), Semi-Trailers, Coaches and Buses. It is also suitable for On Road vehicles that are over 5 tonnes that travel at extended high speeds. 

It has been specially formulated to last longer in fast moving hotter tyres, coping with the additional speed and heat. Utilizing its cooling ability, it can reduce the temperature inside the tyre, making On Road RTG the ideal choice for commercial vehicle operators.

OKO On-Road RTG will seal holes, cracks and slits of up to 10 mm in diameter, helping to prevent punctures and stop air loss deflation as you drive. Given its unique properties, RTG can help extend tyre life by 20% on average, and up to 40% in the case of steer tyres.

Packing: 25 litre drum (optional pump also available)
