FOBO ULTRA IN-CAR SET (Includes 4 x Sensors and 1 x In-Car Unit)

Fobo Ultra is the perfect system for large vehicles/trucks/buses/motorhomes and vehicles towing caravans. Fobo Ultra has the ability to monitor your car, caravan and all your spares in one single application. 

FOBO Ultra is an advanced Wireless Tire Pressure Monitoring System (TPMS) primarily designed for heavy vehicles using latest Bluetooth 4.1 that works directly with your Android and iOS smartphones or tablets. With an intelligent In-Car monitoring unit that works on its own or simultaneously with your smart devices, FOBO Ultra monitors up to 1296 kPa(188 psi) and gives you an alert in the absence of a smart device. Comes with 4 wireless tire sensors, 1 wireless In-Car unit and a 24V 10 feet power cable. Note the unit can be operated independently without wiring with the battery pack included. 

NOTECaravan setups must use an in-car set in the primary tow vehicle regardless of whether the sensors are installed or not as this acts as the receiver for the repaeater set which must be used on trailers or caravans. This ensures the signal is carried effectively to the tow vehicle. While some customers have had success using a single kit it is not recommended and no guarantees are provided if used in this manner.

Easy DIY Installation

install FOBO Ultra without the need for professional help. Just follow the FOBO Ultra app's simple on-screen instructions. You do not need to change or modify your tire's existing pressure valve. Just screw on the FOBO Ultra sensors and you are good to go.


Hook and Drop

It allows trailers or caravans equipped with FOBO Ultra Repeater sets to seamlessly connect and disconnect from different in-car units to form a new chain of clusters with our FIT Technology.


Theft Deterrent

so stolen FOBO Ultra sensors and In-Car unit cannot be reused. Each FOBO Ultra is locked to a specific owner's FOBO cloud account. Furthermore, the package come with anti-theft nut and a small wrench to mechanically lock the sensors from being stolen. Replacement sensors will be available for purchase separately. You will also be notified by the FOBO Ultra App in the event any tire sensor is missing.


Importance of proper tyre inflation 

78,392 crashes (414 fatalities) occurred ANNUALLY in the US due to flat tyres or blowouts before tyre pressure monitoring systems were installed in vehicles 

(ref. NHTSA. (2003, June). “FMVSS No. 139, New Pneumatic tyres for Light Vehicles”, Docket No. NHTSA-2003-15400-2). 

Tyre tread life would decrease by about 8,704km due to driving with under-inflation over its lifetime. That translates to 15-20% of a typical tyre life. 

(ref. NHTSA Docket No. NHTSA-2000-8572-26). 

Fuel efficiency is reduced by 1% for every 3 psi of under-inflation. With proper inflated tyres, US car drivers could save US$11 billion in fuel (US Energy Information Administration - 2013). 

(ref. NHTSA Docket No. NHTSA-2000-8572-26)
