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 Yamaha Fascino 125 Fi Hybrid is distinguished by two remarkable engineering attributes: its featherweight 99 kg kerb weight (making it the lightest 125cc scooter on sale in India) and its unusually wide 110/90-10 rear tyre. While most rival 125cc scooters use a narrower 90mm rear section, Yamaha fitted the Fascino with a broad 110mm rear footprint. This wider tyre provides tremendous straight-line traction and high-speed cornering stability, which harmonizes beautifully with the instantaneous torque boost provided by Yamaha's Smart Motor Generator (SMG) electric hybrid assist. At the front, the Fascino utilizes a standard 12-inch 90/90-12 tyre on cast alloy wheels, delivering crisp, effortless steering in dense urban traffic. Yamaha prescribes 22 psi at the front and 29 psi at the rear for solo riding, raising rear pressure to 36 psi when carrying a pillion. Because the 110/90-10 rear tyre size is less universally stocked than common 90/100-10 tyres, owners should ensure replacement tyres maintain the full 110mm width rather than downsizing to a 90mm tyre that compromises the scooter's planted rear-end feel.

Frequently Asked Questions

Why does the Yamaha Fascino use a wider 110/90-10 tyre on the rear?
The wider 110mm rear tyre provides a broader road contact patch to handle the instant low-end torque boost from the SMG hybrid electric motor while enhancing high-speed stability on the lightweight 99 kg chassis.
Can I replace the Fascino rear tyre with a common 90/100-10 tyre if 110/90-10 is unavailable?
A 90/100-10 tyre will fit onto the rim in an emergency, but it reduces rear contact patch width by 20mm, which makes the scooter feel nervous under hard rear braking and reduces wet cornering stability.
What tyre pressure is recommended for the Yamaha Fascino with a pillion passenger?
Yamaha specifies 22 psi in the front tyre and 36 psi in the rear tyre when carrying a pillion. Riding two-up with underinflated tyres leads to rim strikes against speed breakers.
Do Yamaha Fascino and RayZR 125 share the same tyre sizes?
Yes, both the Yamaha Fascino 125 and the sporty Yamaha RayZR 125 utilize the identical 90/90-12 front tyre and 110/90-10 rear tyre combination.
