Tyre sizes explained
Updated 6 November 2026
How to read a tyre size like 265/65R17 112H, find your car's size, check the DOT production date, and find shops in Qatar with your size in stock.
How to read the size
Take this size as an example: 265/65R17 112H
- 265
- Width of the tyre in millimetres.
- 65
- Aspect ratio: the sidewall height as a percentage of the width (here 65% of 265 mm).
- R
- Radial construction, which almost every car tyre uses.
- 17
- Diameter of the wheel rim it fits, in inches.
- 112
- Load index: the most weight one tyre may carry (112 means 1,120 kg).
- H
- Speed rating: the highest speed the tyre is built for (H means 210 km/h; T is 190, V 240, W 270).
The production date (DOT)
Heat in Qatar ages rubber faster, even when the tread still looks good. The last four digits of the DOT code tell you the week and year the tyre was made. Tyre stock on Markaba shows the DOT date of each tyre when the shop lists it.
Pressure and checks
- Use the pressure on the driver's door sticker, and check it when the tyres are cold.
- Look for cracks or bulges in the sidewalls, especially after the summer.
- A wheel alignment after fitting new tyres helps them wear evenly.

Questions
Where do I find my car's tyre size?
On the sidewall of the tyre itself, on the sticker in the driver's door frame, and in the owner's manual. Use the size the car's maker specifies.
How can I tell how old a tyre is?
Look for the DOT code on the sidewall: its last four digits are the week and year it was made. For example 2324 means week 23 of 2024. Ask to see it before fitting.
Can I fit a different size?
Stay with the sizes the car's maker lists. A different size can affect the speedometer, handling, warranty and insurance; ask a tyre shop first.
