Everything you need to know before buying the Accelera PHI in 255/45 R19 104Y: what the size and ratings mean, which vehicles it suits, and what is included in the fitted price.
01What 255/45 R19 means
Every tyre has its size printed on the sidewall. Here is what 255/45 R19 104Y means:
- 255 — the tyre is 255 mm wide, measured from sidewall to sidewall.
- 45 — the aspect ratio: the sidewall is 45% of the width, about 115 mm tall.
- R19 — radial construction; fits a 19-inch wheel.
- 104 — the load index: up to 900 kg per tyre (3,600 kg for a set of four).
- Y — the speed rating: safe up to 300 km/h when correctly inflated and loaded.
Put together, the overall diameter is roughly 713 mm (about 28.1 inches). If you are changing size, stay within about 3% of the original diameter so the speedometer and safety systems stay accurate.
02Who it suits
The Accelera PHI is a passenger car tyre. It suits passenger cars — saloons, hatchbacks, coupés and estates — used for daily driving in the city and on the highway.
This size carries a Y speed rating. Ratings of W and above are typically specified on performance saloons, sports cars and powerful SUVs.
The surest way to confirm the right size is the placard inside the driver’s door or your current tyre’s sidewall. You can also search tyres by car.
03In UAE conditions
Heat is the biggest factor for tyres in the UAE. Road surfaces regularly pass 60 °C in summer, which raises tyre pressure and speeds up wear and ageing. A few habits help any tyre last longer:
- Check pressures monthly, when the tyres are cold (early morning), and set them to the figure on your door placard.
- Respect the load rating: 900 kg per tyre is the maximum at full pressure. A heavily loaded car on a hot highway is the hardest test for any tyre.
- Rotate the tyres every 8,000–10,000 km so they wear evenly, and have the alignment checked if the car pulls to one side.
- Look for cracks, bulges or tread worn close to the wear indicators (1.6 mm) — replace the tyre if you find any.
04Year of manufacture
The last four digits of the DOT code on the sidewall show when a tyre was made: the week, then the year (for example, 1226 means week 12 of 2026).
The tyres for this listing are from 2026 production, made in Indonesia. We only sell new, unused tyres, and you can check the DOT code yourself when they are fitted.
