Hero Maestro Tyre Size for the Maestro Edge 110 and 125

Maestro tyre size, Edge 110 against Edge 125

Both engine sizes share one frame and one set of wheels; the fitter can ignore which badge your side panel wears. The hero maestro tyre size answer is identical for either.

What 90/90-12 54J and 90/100-10 53J tell you

Take the rear first. Its 90 gives width in mm; 100 says the sidewall height equals that width, so 90 mm again; 10 gives rim inches. The front 90/90-12 has the same width, a sidewall of 81 mm, and sits on a bigger 12 inch rim.

The 54 at the front allows 212 kg per tyre and the 53 at the rear allows 206 kg. The letter J allows 100 km/h. A replacement may carry a higher code than these, never a lower one; see tyre load index for how the numbers run.

Why a bigger front wheel helps on this scooter

The 12 inch front rolls into a pothole less deeply than a 10 inch wheel and steadies the handlebar at 60 km/h on a ring road. Hero kept the rear at 10 inch so the engine and the boot under the seat stay compact. For an owner this means two separate tyres in the parts list, and a front that usually outlasts the rear by a good margin.

Maestro scooter tyre size swaps that keep the height

Two alternatives come up at shops. At the back, a 100/90-10 measures the same overall diameter as stock, about 434 mm (254 mm rim plus two 90 mm sidewalls), just 10 mm wider. At the front, a 100/80-12 comes to roughly 465 mm, a hair under the 467 mm of the original.

Diameter is only half the question. The Edge has a snug rear mudguard and a silencer close to the wheel, so extra width can touch when the shock compresses with two riders. A good fitter spins the wheel slowly, scooter loaded, watching that gap; keep the load code at 53 or above. The factory pair remains the safest answer.

Punctures and tubeless repairs

Both Edge tyres are tubeless. A screw in the tread lets air out slowly, which normally buys you the minutes needed to roll slowly to a repair stall. Leave the screw where it is until you get there. On 10 inch rear wheels, ask the repairer to check that the bead has seated evenly after refilling; small beads sometimes need a second push. Read more under tubeless tyre.

Pressure for the Edge

Riding alone, an Edge wants 22 psi on the 12 inch wheel and 29 psi on the 10 inch one, cold. Two up, leave the 22 alone and take the back tyre to 36 psi. The rear figure matters most because a soft 10 inch tyre flexes hard over speed breakers and heats up on long summer rides.

Signs the Maestro needs fresh tyres

The back tyre on an Edge dies first, since it both pushes and bears the load. Run a fingernail across the middle grooves: when they feel shallow and the tiny tread markers inside them are flush with the surface, it is time. Squared off edges, cracks from parking in the sun, or a wobble at 40 km/h are other signs. A bulge or a gash in the side wall needs a technician's eye straight away; ride slowly to one and no further.
