IRC Scooter Tyre 140/70-14

The IRC Scooter Tyre 140/70-14 is a dedicated replacement tyre size commonly used for larger scooters and maxi-scooters. The specification “140/70-14” describes a width of 140 mm, aspect ratio of 70% (height is 70% of the width), and designed to fit a 14-inch rim. Made by IRC (Inoue Rubber Co., Ltd.), a Japanese-origin tyre manufacturer known for scooter/motorcycle tyres. Their manufacture supports scooter-specific tread patterns and casing dynamics to cater for urban commuting and occasional sporty riding.

The tyre is tubeless (in most versions), offering improved convenience and modern mounting compatibility. Given the size and width, it provides a relatively large contact patch for better stability, especially useful for heavier scooters or when carrying two riders and luggage. Users note availability of various tread patterns for this size, including standard road-use compounds and sport or “stock grip” variants.
Reported listings show this size being marketed for compatible scooter models using 14-inch wheels.
