TOST 5" Landing Wheel
TOST 5″ Landing Wheel
General Description
TOST 5″ Landing Wheel Classic - This is used as a nose wheel in aircraft. Also, for heavy-duty applications, wheel hub with six–fold bolting, manufactured from aluminum die–cast with deformable fins sector.
TOST 5″ Landing Wheel Penta - This can be used to save weight and as a possible replacement for landing wheels equipped with inch bearings. They are CNC milled from solid and feature a low weight and stable high load capacity due to the high–tensile aluminum alloy. The wheel halves are fivefold screwed. Thanks to the set distance bushing a distortion of the bearings on the axle is not possible. Due to the asymmetric splitting of the wheel hub and the use of tire and tube, a fast and straightforward change of the tire – without special tools and special repair shop equipment – is possible. The anodized surface of the Penta wheel hubs provides the maximum corrosion protection.
5″ Landing Wheel Classic Seawater Resistant - For use in amphibians or equipment exposed to saltwater we manufacture the 5″ landing wheel Classic also as a seawater-resistant version. With a special surface treatment, bearings from stainless steel with special seals and coated wheel bolts these wheel hubs are highly corrosion-resistant.
5″ Landing Wheel Tubeless - To realize a further weight reduction you can use our 5″ wheel tubeless. The weight decrease is about 15% in total weight compared to a wheel hub with tire and tube (tube type TT). The exchange of the tire is relatively easy to handle, contrary to other TL wheels.
TOST 5″ Landing Wheel price varies depending on selection. Use dropdown box above for selection and final price.

Notes to aircraft tires
Tire exchange
Removal:
- Jack up aircraft at specified point.
- Deflate tire completely before removing wheel unit.
- Do not unscrew the valve insert until the tire pressure has dropped to 0.2 bar.
- Remove wheel from axle.
- Loosen wheel bead from the hub shoulder with a rubber or plastic hammer.
- Undo wheel bolts (with 5 mm hexagon key), remove bolts and washers, split hub halves.
Mounting:
- Tires and wheel hubs must be clean and dry.
- Do not apply excessive force when replacing a wheel.
- Apply adhesive agent (or talcum powder) to the hub shoulder.
- Remove dirt, sand, labels, etc. from the tire. Apply a moderate amount of talcum powder to reduce friction between tube and tire.
Caution: Too much talcum has the opposite effect. - Fill air into tube (placed in the tire) until it is evenly round. Remove nut and washer from valve.
- Place tire (red mark at valve hole) and tube on the wheel half with the valve hole, push valve through valve hole
- Push other wheel half onto tire, match bolt holes with centering shaft.
- Insert wheel bolts, washers and any nuts, and tighten to the correct torque (M6: 9 to 10 Nm). Tighten bolts diagonally.
- Place a tire in a safety cage when inflating it to mounting pressure for the first time. If you do not have a safety cage, take great care when inflating the tire. Inflate the tire to mounting pressure. The mounting pressure is 10% more than the specified operating pressure. Check carefully for leaks. Leave to adjust at this pressure for 12 to 24 hours. Once the tire shows no leaks and is at operating pressure, the wheel unit can be mounted on the aircraft.
- Make sure that the wheel unit is mounted perfectly balanced to avoid vibration and excessive wear.
Red Dot:
Larger aircraft tires are marked with a red dot. This is an indication of the lightest spot of the tire. The valve must be placed at this point to eliminate or minimize a balance/vibration problem of the tire.
WARNING:
An inflated tire is a potentially explosive device – treat it with the correct equipment and precautions!
Notes on inner tubes
Aircraft tubes are made from natural rubber, and they are slightly underdimensioned so that it is easier to install them in a new tire. The layers of an aircraft tire are made of nylon – they therefore tend to become larger with use.
The inner tube also increases in size, adapting to the larger inside diameter of the tire. If a tube enlarged in this way is later fitted in a new tire, it can happen that it is too big for the inside of the tire, with the result that the tube may crease.
These creases may rub through during operation, causing the tube to lose pressure. Rubbing through slowly results in slow pressure loss – the pilot is thus warned before a dangerous situation arises. If the tube tears during a start, the pilot will fail
to notice that he is flying with a flat tire.
Taking into consideration all the risks involved with fitting an old tube into a new tire, it is advisable always to fit new inner tubes in new tires.
Tire maintenance instructions
- Maintain stipulated air pressure, check at regular intervals! Underpressure results in reduced load capacity and shortens service life.
- Inspect tires at regular intervals for damages, shredding, flat areas and foreign objects.
- Wheel units must be mounted perfectly balanced. Wheel imbalance can result in a damage to bearings and brake drums.
- Keep tires free of oil, grease, brake fluid and tar. Clean tires with rag soaked with petrol, then wash off with soap and water.

TOST Aircraft Wheels
In 60 years of development and production of high–grade aircraft wheels, TOST has created a vast product variety and delivery program. TOST wheels are worldwide used in gliders, motor gliders, aircraft, ultralights, amphibian aircraft and helicopters. Also, in heavy–duty applications TOST wheels convince with high load factors and customer oriented solutions. High serviceability is an important feature of an aircraft wheel. That’s why we pursue our philosophy of wheel hubs for tube type tires. You can easily change the tire with standard tools, even on the airfield. The operation of TOST wheels is very economic. Not only the quality and lifetime persuade, but also the ease of maintenance: the wheel hubs are maintenance–free and fitted with high–quality groove ball bearings. TOST can supply spare parts over decades and offer maintenance and repair of your wheels. TOST wheels MADE IN GERMANY are a synonym for highest quality and reliability.
