Everything you need to know before buying the Continental Sport Contact 7 in 255/45 R20 105V: what the size and ratings mean, which vehicles it suits, and what is included in the fitted price.
01What 255/45 R20 means
Every tyre has its size printed on the sidewall. Here is what 255/45 R20 105V 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.
- R20 — radial construction; fits a 20-inch wheel.
- 105 — the load index: up to 925 kg per tyre (3,700 kg for a set of four).
- V — the speed rating: safe up to 240 km/h when correctly inflated and loaded.
Put together, the overall diameter is roughly 738 mm (about 29.1 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 Continental Sport Contact 7 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 V speed rating. A V rating is common on premium saloons, larger SUVs and cars with more powerful engines.
20-inch wheels are usually fitted to larger SUVs and performance cars, so low-profile sizes like this give sharp steering but less sidewall to absorb potholes — keep pressures at the level on your door placard.
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: 925 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).
