(1) SOLID - rubber tyres - fitted on steel or plastic (polypropylene) rims with plain or roller bearings depending on application. No good on grass, gravel or uneven surfaces.


(2) PNEUMATIC - 4 ply tyres on steel rims with roller bearings. Rarely used by us due to problems with 
punctures.


(3) PNEUMATIC + ‘OKO’ anti-puncture treatment. Reduces the frequency of punctures but does not eliminate them completely - other characteristics same as (2).


(4) PNEUMATIC + ‘GEL’ completely filled with a polyurethane GEL instead of air - totally puncture proof - takes a higher load than MCP tyres. These tyres are much heavier than (2), (3) or (5).



(5) MCP - MICRO-CELLULAR POLYURETHANE tyres (like a dense sponge) fitted on steel or plastic (polypropylene) rims with roller bearings (plain bearings on OUTBOARDER-SLEDGE). Run just like pneumatic tyres but are totally puncture proof. Quiet running and non marking. Highly recommended!!
