The Glanza tyre size is 185/65 R15 for E and S grades (CNG too) and 195/55 R16 for G, V and V(O) cars. No Glanza mixes sizes front to rear, and Whatever the grade, Toyota supplies a 185/65 R15 Glanza spare on a steel rim, stowed beneath the luggage floor.
When a customer rolls a Glanza into my bay, the first thing I check is the wheel. Black steel behind a full plastic cap means the 15 inch fitment. A polished alloy with a centre cap means 16 inch. Read on for a grade chart, the sidewall code decoded, how the steel spare behaves on alloy cars, and which alternative sizes make sense.

Glanza tyre size chart by grade
| Variant | Front | Rear | Wheel |
|---|---|---|---|
| E | 185/65 R15 | 185/65 R15 | 15 inch steel, full wheel cap |
| S, S AMT, S CNG | 185/65 R15 | 185/65 R15 | 15 inch steel, full wheel cap |
| G, G AMT, G CNG | 195/55 R16 | 195/55 R16 | 16 inch polished alloy |
| V, V AMT | 195/55 R16 | 195/55 R16 | 16 inch polished alloy |
| V(O) | 195/55 R16 | 195/55 R16 | 16 inch polished alloy |
| Spare, every grade | 185/65 R15 | 15 inch steel |
The gearbox and fuel make no difference. An S CNG wears the same rubber as a petrol S, and a G AMT matches a manual G. Only the grade decides the wheel, so a quick look at the rim tells you which size to order.
Reading the code on a Glanza sidewall
- 185 or 195: how wide the Glanza tyre is, in mm. The G and V tyre is 10 mm wider.
- 65 or 55: Glanza sidewall height, given as a percent of tread width. That gives the E and S a wall close to 120 mm tall, against roughly 107 mm on alloy grades.
- R: radial build; no Glanza uses a tube.
- 15 or 16: rim diameter in inches.
Next to the Glanza size you will find two digits and a letter: a code rating how much each tyre carries and its maximum speed. Copy it from your old tyre and ask for the same or higher. A family Glanza packed for a hometown trip needs every bit of that rating.
Why both Glanza fitments end up equally tall
Toyota picked two sizes that end up almost exactly as tall. So a base E and a loaded V read the same on the speedo and sit at the same ride height.
| Size | Working | Overall diameter |
|---|---|---|
| 185/65 R15 | 381 + 2 x 120.25 | 621.5 mm |
| 195/55 R16 | 406.4 + 2 x 107.25 | 620.9 mm |
The gap is well under a millimetre. That means a steel wheel Glanza can take the G grade alloy with its 195/55 R16 tyre without rubbing or a speedo error, provided the wheel copies the factory part in its bolt circle, hub hole and offset. Our Glanza alloy wheels page covers those wheel numbers.
Going larger than stock on a Glanza
Owners often ask for a 17 inch look. Worked out, a 205/45 R17 stands about 616.3 mm, less than 1 percent below stock. Yet no Glanza was ever sold on 17s, so nobody has signed off that it clears the arch liners at full lock with the car sitting low under load.
- Less sidewall means sharp jolts and bent rims from craters and unpainted speed breakers.
- Extra width adds weight to the steering in parking lots and trims fuel economy.
- A non standard size can invite questions from the insurer or the service advisor after a claim.
For most city and highway use, the factory 195/55 R16 is the sensible upper limit. A 185/60 R15 is not a good swap either: it comes out about 3 percent shorter and lowers the car.
How the steel spare works on alloy Glanzas
For steel wheel grades the spare is simply a fifth matching tyre. Alloy grades get the narrower 15 inch spare, which still turns at the right speed since its height equals the 16 inch tyre. Drive on it gently to the nearest repair stall, then swap the fixed alloy back on quickly so you are not running odd tread patterns for weeks. Check its pressure each month too. A spare that has been sitting flat for a year is no help on a dark highway shoulder.
First generation Glanza sizes
Toyota offered the first Glanza in just two grades, G and V, each riding on 16 inch diamond cut alloys. Owners of those cars ask for 195/55 R16, exactly what a current alloy grade takes. The difference is the wheel finish: diamond cut faces scratch and corrode more easily than painted or polished ones, so take care at roadside puncture shops that use tyre levers on the rim lip.
When your Glanza needs new tyres
Glanza tyres have little wear bars across the grooves that mark the 1.6 mm minimum. On wet monsoon roads grip falls off well before that, so many owners change at 2 to 3 mm. Age cracks, a blister on the wall or a gash exposing cords all mean the tyre needs a tyre shop inspection; crawl there and go no further. Change tyres two at a time on one axle, with the fresher pair fitted at the back so the tail stays planted on wet tarmac. Keep the pressure right as well, using our Glanza tyre pressure guide.
How the Glanza compares with similar hatchbacks
The Glanza shares its sizes with the Baleno tyre size chart, since the two cars are built on the same body. For a wider list of cars and how sizes are written, see our car tyre size hub. If you are cross shopping, the i20 and Swift pages give their own fitments.
Questions owners ask
Which size does the top Glanza grade take?
Alloy grades up to the V(O) use 195/55 R16, while the spare remains a 185/65 R15 steel wheel.
What is the Glanza base model tyre size?
Steel rim grades, E through S CNG, take 185/65 R15 on 15 inch wheels hidden under full plastic caps.
Does the CNG Glanza use a different tyre?
It does not. Fuel type never changes the fitment; each CNG car shares rubber with its petrol twin grade. The tank sits in the boot, so check rear pressure more often when you carry luggage on top of it.
Will 16 inch rubber go on a Glanza S?
Yes, with 16 inch wheels that copy the factory G alloy's fitment numbers. Since 195/55 R16 equals the stock tyre in height, the speedo reading does not shift.
Do the Glanza and Baleno share tyres?
Yes. Both cars use 185/65 R15 on lower grades and 195/55 R16 on upper grades, so tyres and wheels cross over between them.
Are Glanza tyres tubeless?
They are, spare included. Small Glanza tread punctures from nails are normally fixed with a plug, wheel still bolted on.
