190. 自転車タイヤ
自転車タイヤは、自転車の車輪周囲へ取り付けられ、道路など走行面との接触を担うゴム製タイヤです。トレッド、空気圧、幅、構造はグリップ、転がり抵抗、快適性、操縦性へ影響します。
適切な空気圧を保ち、摩耗、切れ、ひび、異物の刺さりなどを定期的に点検します。適切な種類と空気圧は自転車、利用者、荷重、走行条件によります。
Is there a minimum tread depth for bicycle tyres in Belgium?
The current Belgian rules for bicycle equipment do not specify a general numerical minimum tread depth for ordinary bicycle tyres. Cyclists should nevertheless replace tyres that are excessively worn or damaged because their condition directly affects grip and safety.
Can Belgian bicycle tyres provide the required side reflectors?
Yes. A bicycle can satisfy the side-reflector requirement by having a continuous white retro-reflective strip on each side of both the front and rear tyre. Alternatively, suitable yellow or orange reflectors can be fitted to the spokes.
Does tyre width affect how some bicycles are classified in Belgium?
Yes. Tyre dimensions form part of the definitions used for certain bicycle categories. For example, a racing bicycle can have tyres with a cross-section of no more than 25 mm, while specified mountain-bike categories use wider minimum tyre sections.
