What This Size Means
90 = tread width in millimetres. 90 = aspect ratio, meaning the sidewall height is 90% of the tread width (81 mm). R = radial construction (or bias-ply if dash-indicated). 12 = wheel rim diameter in inches (305 mm).
Editor's Technical Insight
The Honda Dio has long been the scooter of choice for younger Indian commuters and college students who desire aggressive, edgy moto-scooter styling over the conservative metal lines of the Activa. Like the latest Activa, modern BS6 Dio iterations employ a staggered wheel arrangement with a 12-inch 90/90-12 front tyre and a 10-inch 90/100-10 rear tyre mounted on either pressed steel or golden alloy rims. The Dio's lightweight all-plastic bodyshell makes it roughly 3-4 kg lighter than the Activa, resulting in snappy flickability through tight city traffic gaps. Honda recommends 22 psi at the front and 29 psi at the rear for solo riding (36 psi with a pillion). Young riders frequently push the Dio aggressively through urban roundabouts and wet corners; installing high-silica tyres with sporty directional water grooves like the CEAT Zoom D or TVS Dragon substantially reduces wet front-wheel slide under sudden activation of the linked Combi-Brake System (CBS).
