Determine Tire Size: Read, Understand, and Order 205/55 R16 & Co. Correctly
Determining Tire Size: Reading, Understanding, and Correctly Ordering 205/55 R16 & Co.
Determining tire size is the foundation for every good tire purchase – especially if you want to buy tires online. Many drivers in Landshut, Bavaria, and Lower Bavaria are surprised at how easily numbers and letters can be confused. Yet, with clear instructions, it's much simpler than it appears at first glance. In this article, you will learn how to correctly read 205/55 R16 & Co., what load index and speed index mean, and how to confidently make the right order in just a few minutes.
How to read tire specifications correctly
A typical example is: 205/60 R16 92H. This combination initially looks technical, but it follows a clear logic. Once you understand the individual components, you can compare tire sizes much more confidently and avoid incorrect purchases.
- 205 = Tire width in millimeters
- 60 = Aspect ratio (height to width)
- R = Radial construction
- 16 = Rim diameter in inches
- 92 = Load index (load capacity)
- H = Speed index

Where to find the correct tire size?
You usually find the right tire size faster than many think. These three places are particularly helpful:
- in the vehicle registration certificate (Fahrzeugschein)
- on the sidewall of your currently mounted tires
- sometimes on stickers in the door frame or on the fuel cap
Important: Stickers in the vehicle often show recommended tire pressure values, but they can still be a useful hint for permissible combinations. The safest method is always to cross-reference with vehicle documents and the current tires.
Why load index and speed index are not secondary matters
Many think: "If the size is right, everything else will fit." But this is exactly where many mistakes happen. The load index and speed index are safety-relevant and must not simply be ignored. A tire must be able to reliably carry the vehicle's weight and be suitable for the permissible speed.
Especially during long journeys, with a full load, or on Autobahn stretches in Bavaria, an unsuitable index can become a real problem. Those who order tires online should therefore not only pay attention to the initial number but always check the complete marking.
Mini-table: What to check when comparing
This simple overview helps you quickly compare suitable tires online:
| Criterion | What you check | Why it's important |
|---|---|---|
| Size | e.g., 205/60 R16 | Fits on rim and in wheel arch |
| Load Index | e.g., 92 | Safely carries vehicle weight |
| Speed Index | e.g., H | Suitable for permissible speed |
| Season | Summer / Winter / All-season | Affects grip and safety depending on weather conditions |
How to find suitable tires in the shop
Once you have accurately determined the size, ordering becomes much easier. You can start broadly with Tires or filter directly by season:
If you need a frequently searched size, size-specific categories often help. Examples include Summer tires 205/60 R16 or Winter tires 205/65 R16.
This saves time because you don't have to filter through general categories for long. Especially when buying online, this is one of the biggest advantages: you get from technical data comparison to the right order faster.
Typical errors when determining tire size
- Confusing aspect ratio and rim size: The 60 is not the rim size – the 16 stands for the rim diameter.
- Overlooking load index or speed index: Size alone is not enough.
- Ordering a "similar" size: This can work, but it must be technically and legally permissible.
- Only looking at the price: Fit and safety always come first.
When in doubt, it is always worth an additional comparison with manufacturer specifications or vehicle documents. Small deviations often seem harmless online but can quickly become problematic in practice.
Mini-check before ordering
Before ordering, it's best to check these points again:
- is the complete tire size correct?
- do the load index and speed index match?
- have you chosen the correct season?
- does the tire really suit your vehicle and your driving profile?
This short check significantly reduces the risk of incorrect orders and makes your purchase more relaxed.
Conclusion: Determine tire size and then buy safely online
Once you have accurately determined tire size, the actual tire purchase becomes much easier. Check size and index, compare suitable models, and filter directly via Tires or in New Tires.
Especially in Landshut, Bavaria, and Lower Bavaria, you will avoid incorrect purchases, unnecessary trips, and later surprises. Determining tire size is ultimately the most important step – and once that's sorted, the rest is convenient.
