When the direct TPMS warning light comes on, either one of the tires is under-inflated, severely over-inflated, or there is a fault with the system. [1] If the light is constant then inflating to the correct placard pressure should turn it off. If this is not the case then this indicates a puncture.
A discharged battery means that the tire must be dismounted in order to replace it, so long battery life is desirable. To save energy and prolong battery life, many dTPMS sensors do not transmit information when parked (which eliminates spare tire monitoring) or apply a more power expensive two-way communication which enables wake-up of the sensor.
Some such pumps are designed to cut off before a suitable pressure (much higher for a bicycle than a car tire), and will much under inflate the tire. Others may not cut off, but deliver a high rate of flow to fill the larger car tire, with a risk of over inflating and bursting a bicycle tire unless it is stopped with split-second timing ...
A battery stocks up energy as a chemical reaction. This means that the bike is constantly stocking up energy when ridden on easier terrain, and then using that energy when going uphill, in the ...
The recommended inflation pressure is found in the owner's manual and on the vehicle's tire placard. [ 3 ] [ 4 ] Because of slow air leaks, changes in the weather and ambient temperature or other conditions, tire pressure will occasionally have to be corrected via the valve stem with compressed air which is often available at service stations.
Colorized tire footprint pressure distribution. The contact patch is the portion of a vehicle's tire that is in actual contact with the road surface.It is commonly used in the discussion of pneumatic (i.e. pressurized) tires, where the term is used strictly to describe the portion of the tire's tread that touches the road surface.
A tire valve goes through a hole in the rim, and the hole slightly weakens the rim. Presta valves are thinner than Schrader valves, so can fit through a smaller hole. For bicycle rims which are narrow and lightweight (thus highly stressed), a smaller hole makes the rim and wheel stronger.
Nissan is urging the owners of about 84,000 older vehicles to stop driving them because their Takata air bag inflators have an increased risk of exploding in a crash and hurling dangerous metal ...
