350×4 SID STL 20 Bearing Semi Pneumatic Wheel

Our premium Australian made polyurethane foam-filled tyres provide the greatest performance and reliability. The foam filling provides a light-weight bouncy performance, similar to air-filling, but without the risk of flat tyres.

These wheels boast 4 ply long life tyres, fitted to two piece wobble-free steel centres that are manufactured from thick 1.8 mm steel, unlike cheaper imports with 2 ply tyres and rims made from thin 0.6 mm steel.

Polyurethane foam-filled tyres are the premium ‘pneumatic’ (or semi-pneumatic) wheel option. The wheels are puncture proof and provide the greatest performance and reliability. Semi-pneumatics are fitted to two piece wobble-free centres, manufactured from 1.8 mm steel.
