The Aviator tyre size combination is 90/90-12 ahead plus 90/100-10 behind, shared by every version from Drum to Disc. That larger 12 inch front was this Honda's selling point, giving calmer manners over potholes than the usual 10 inch scooter front.
Honda has stopped selling the Aviator, yet many still handle office commutes and school pickups. Because its two wheels differ, a front tyre will never bolt onto the back, and a shop has to stock two separate sizes.

Aviator tyre size for Drum, Drum Alloy and Disc
| Variant | Front | Rear | Wheel |
|---|---|---|---|
| Drum | 90/90-12 | 90/100-10 | 12 inch front, 10 inch rear |
| Drum Alloy | 90/90-12 | 90/100-10 | 12 inch front, 10 inch rear |
| Disc | 90/90-12 | 90/100-10 | 12 inch front, 10 inch rear |
Only the brakes vary between these three. Someone riding a Disc model buys exactly the rubber a Drum rider buys.
What the two Honda markings tell you
- 90/90-12 on the steering wheel: 90 mm wide, wall height nine tenths of width, near 81 mm, on a 12 inch rim. Total height lands around 305 + 2 x 81 = 467 mm.
- 90/100-10 behind: equally 90 mm wide, but its wall matches the full width, about 90 mm, around a 10 inch rim. Total height reaches about 254 + 2 x 90 = 434 mm.
That taller back wall makes up part of the smaller rim, so the scooter sits fairly level. It also cushions bumps when a pillion rides along with groceries on the floorboard.
Aviator tyre pressure in psi
| Load | Front (cold) | Rear (cold) |
|---|---|---|
| Rider only | 22 psi | 29 psi |
| Rider and pillion | 22 psi | 36 psi |
Front air stays put, but the back needs 7 psi extra once two people climb on. Many owners skip that, and a soft rear then scrubs its edges and makes the Aviator wallow in turns. Check cold, before setting off, and follow Honda's handbook. Riders who think in bar can convert using our psi, bar and kPa tool.
Buying replacement Aviator tyres
A 90/100-10 rear is a very common scooter fitment, so almost any outlet has it. A 90/90-12 front is rarer among older scooters, and a small neighbourhood shop might need a day to source one. Say which wheel needs rubber and carry the worn tyre along.
Check two details at the counter. First, TUBELESS moulded on the wall if your rims are tubeless type; listings differ on whether every Aviator had them, so mirror what is fitted today. Second, freshness: four digits printed inside an oval on the rubber reveal when it was moulded. Rubber left on a warehouse shelf for ages turns hard and slips on wet tiles at a society gate. Decoding that stamp takes a minute with our tyre manufacturing date walkthrough.
Should you change the size?
Rarely worth it. Scooter mudguards and the engine casing beside the back wheel leave little space, and something wider can rub when loaded. Stay with Honda's pair. For better grip, choose a deeper, more open tread in identical dimensions, which clears water faster in monsoon downpours.
Wear, damage and safety
Scooter rears go quickly because the engine drives them directly and they bear most of the weight. Watch for bars flush with tread, splits in groove bottoms, and flat patches from hard stops. A bulge or slash in a sidewall means replacement; crawl to the closest fitter and let them examine it. Keep the front healthy as well, since it handles most braking on any scooter.

Questions owners ask
What is the Honda Aviator front tyre size?
Honda fitted 90/90-12 on a 12 inch wheel. That is bigger than most scooter fronts, which helps over potholes.
Which tyre fits the Aviator's back wheel?
A 90/100-10 on a 10 inch wheel. It cannot swap places with the front.
Do Drum and Disc Aviators use different tyres?
No. Drum, Drum Alloy and Disc all wear 90/90-12 ahead and 90/100-10 behind.
What pressure should an Aviator run?
22 psi up front. Behind, 29 psi riding alone and 36 psi carrying a pillion, all measured cold.
Is the Aviator discontinued?
Yes, showrooms no longer stock it. Both of its tyre sizes are still manufactured and simple to find.
