Tyre Inflation and Replacement
The BRUNO employs 27.5"X2.3" rubber tyres witch inner tubes. The tyres are designed for durability and safety during regular cycling activi -
ties; they should be checked before each use for proper inflation and condition. Proper inflation, care, and timely replacement ensure that
your bike's operational characteristics are maintained, avoiding unwanted, unsafe situations. JOBOBIKE recommends
35- 60 psi/2.5 – 4.1 bar for both the front and rear tyres. Always stay within the manufacturer's recommended air pressure range as listed
on the tyre sidewall.
It is critically important that proper air pressure is always maintained in pneumatic tyres. Do not underinflate or overinflate your tyres. Low
pressure may result in loss of control, and overinflated tyres may burst. Failure to always maintain the air pressure rating indicated on
pneumatic tyres may result in tyre and/or wheel failure. Inflate your tyres from a regulated air source with an available pressure gauge. In -
flating your tyres from an unregulated air source could overinflate them, resulting in a burst tyre.
Even tyres equipped with built-in flat-preventative tyre liners can get flats from punctures, pinches, impact, and other causes. When tyre
wear becomes evident or a flat tyre is discovered, you must replace the tyres and/or tubes before operating the bike or injury to operators
and/or damage to your bike could occur.
When changing a tyre or tube, ensure that all air has been removed from the inner tube prior to removing the tyre from the rim. Failure to
remove all air pressure from the inner tube could result in serious injury, unsafe riding condition, or damage to your bike. If required by law,
and for adequate visibility, ensure replacement aftermarket tyres have sufficient reflective sidewall striping.
