The Honda Grazia tyre size lists 90/90-12 up ahead with 90/100-10 out back, each tubeless, and every Grazia variant shares that pairing. The base drum version rolls on steel rims while the disc and special edition versions get alloys, yet tyre codes stay identical.
Honda gave the Grazia a bigger twelve inch front to make it feel more planted than older ten inch scooters, while the compact ten inch rear keeps the underseat storage roomy. Below are the details owners ask about most at the tyre counter.

Grazia tyre size across variants
| Variant | Front | Rear | Wheel |
|---|---|---|---|
| Grazia drum (base) | 90/90-12 | 90/100-10 | 12 inch front, 10 inch rear, steel |
| Grazia disc | 90/90-12 | 90/100-10 | 12 inch front, 10 inch rear, alloy |
| Special and sports editions | 90/90-12 | 90/100-10 | 12 inch front, 10 inch rear, alloy |
A few online listings show the rear as 90/90-10, but most specification sheets agree on 90/100-10. Before buying, confirm by reading your existing rear tyre. Honda uses this same twelve plus ten pairing on the current Activa, so stock is easy to find almost anywhere.
Understanding the Honda Grazia tyre size codes
| Tyre | Sum | Overall height |
|---|---|---|
| 90/90-12 front | 81 x 2 + 305 | about 467 mm |
| 90/100-10 rear | 90 x 2 + 254 | about 434 mm |
Both tyres are 90 mm wide. The rear has a taller sidewall, one hundred percent of its width, which partly makes up for its smaller rim and adds cushioning where the rider and pillion sit. Our sidewall decoder covers every letter and number you may see.
Cold pressure in psi
| Load | Front | Rear |
|---|---|---|
| Rider only | 22 psi | 29 psi |
| Rider and pillion | 22 psi | 36 psi |
Notice how the nose number never moves; extra air goes only into the back tyre once a passenger climbs on or the boot holds heavy shopping. Top up at dawn, while rubber is still cool. Forecourt dials drift, so a pocket gauge earns its keep. Moulded maximums near the bead describe casing limits, never fill targets. Need bar or kPa? Use our pressure converter.
Can the rear go wider?
Some riders request a 100/90-10 behind, chasing a beefier stance. The numbers work out neatly:
| Rear size | Sum | Overall height |
|---|---|---|
| 90/100-10 (stock) | 90 x 2 + 254 | about 434 mm |
| 100/90-10 | 90 x 2 + 254 | about 434 mm, same height, 10 mm wider |
Overall diameter holds steady, meaning speedo accuracy survives. The extra width must clear the body panel and the rear mudguard; ask the mechanic to confirm gaps before riding away. Honda never offered it on any Grazia, so stick with the factory 90/100-10 if you want handling exactly as designed. Leave the front at 90/90-12.
Pothole damage on the small rear wheel
Small ten inch hoops ride low, so a sharp crater can trap rubber between road and rim lip. On steel rims you may get a bent lip that leaks slowly; on alloys a hard hit can crack the wheel. After a heavy jolt, look for a bulge on the tyre wall or a dent on the rim and let a mechanic check it. Running correct pressure is the best protection, because a soft tyre folds easily against the rim.
Replacement timing and tubeless repair
Most Grazia riders replace the rear first. Check grooves against the wear bar markers, look for cracks if the scooter is parked in the sun, and read the age stamp using the manufacturing date guide. Little nail holes across the tread accept a plug; the tubeless tyre page explains the method. Sidewall cuts mean a new tyre.

Questions owners ask
What is the Grazia tyre size?
Steering wheel: 90/90-12. Drive wheel: 90/100-10. Tubeless throughout the range.
Does the Grazia drum variant use different tyres from the disc?
No. The drum base model has steel rims and the disc model has alloys, yet both wear identical rubber.
What tyre pressure should the Grazia run?
Solo and cold: 22 psi ahead, 29 psi behind. Two up: keep 22 ahead and pump the back to 36 psi.
Is the Grazia rear tyre the same as the Activa rear tyre?
The current Activa also uses a 90/100-10 rear, so the same size fits. Check your own sidewall to confirm before buying.
Would 100/90-10 work behind on a Grazia?
Its height matches the stock size, but it is wider and not a factory fitment. Ask a fitter to check body and mudguard clearance.
Why does the front tyre look bigger than the rear?
It sits on a twelve inch rim versus ten inches at the rear. The larger front wheel gives steadier steering over rough roads.
