What does 205 55 R16 91h mean?
The markings usually look something like this: 205/55 R16 91V. The first number (205) tells you the width of the tyre in millimetres. The second number (55) tells you the height of the tyre as a percentage of the width. The letter (R) stands for “Radial” which is the type of tyre. Example P205/55R16 91W. P identifies your tire as a Passenger Tire. The P stands for PMetric. If your tire size starts with LT rather than a P than it identifies the tire as a light truck tire.As an example, for a tyre with the markings 205/55/R16/ 91V, 205 denotes the width of the tyre in millimetres, 55 denotes the tyre’s aspect ratio, which is the sidewall’s height given as a percentage of the width, R16 specifies that it is a radial tyre with an inside diameter of 16 inches and 91V indicates the load .The numbers give the load rating for the tire, while the letter indicates the speed rating. Using P215/65R15 85H as an example, the 85 gives the load index, also called the tire ply rating, and the H is for the speed rating, which tells you the maximum speed at which you should use the tires.Generally, the higher in the alphabet a tire is rated, the better it will manage heat and faster speeds.
Is 40 too high for tyre pressure?
No, for most cars a tire pressure of 40 psi is too high. You might find 40 psi suitable for some vehicles, especially if they’re carrying heavier loads or if the manufacturer’s recommendation is close to that figure. However, it’s generally too high for most passenger cars, which usually recommend between 30-35 psi. Tire pressure increases when the tires are used, and for this reason, following the vehicle and tire brands’ recommendation is crucial. Typically, if the recommended pressure levels are 35, then the tires should not use more than 40 psi. More than that will result in the before mentioned problems.You’ll also find the correct air pressure for your car’s tires listed on a sticker located on the lower part of the driver-side door jamb. For many passenger cars, the recommended air pressure is 32 psi to 35 psi when the tires are cold. There is also a tire pressure number shown on the sidewall of the tire itself.Based on normal tire sizes for each segment, small-sized car are usually 30 psi, medium-sized cars are 36 psi, and large cars are 42 psi. Keep in mind that warm tires normally exceed recommended cold tire pressures by 4-6 psi.However, as a general guideline, the recommended tyre pressure for 205/55 R16 tyres typically falls within the range of 30 to 35 PSI (pounds per square inch) for passenger vehicles.
What is the correct tyre pressure for 205 55 R16?
How much tyre pressure for 205/55 R16 tyres. Properly inflated tyres are essential for safe driving. Correct, average 16” front and rear axle tyre pressure should be between 2. BAR and between 2. BAR respectively. The recommended tire pressure for most vehicles typically falls between 30 and 35 PSI.

What does 205 55 R16 mean on a tire?
Marking 205/55 R16 means that the height is 55% of the width. It is easy to calculate: 205 • 55% (0. The larger the B value in the formula, the higher the tyre will be and vice versa. This parameter is very important. Using a 195/65R15 91H tyre size as our example, the first part – 195 – corresponds to the width of the tyre. This is an aspect ratio against the next number, 65 – which relates to the sidewall, or profile, of the tyre. The next part – R15 (or ZR15) is the diameter of the wheel that the tyre is for.
What does AO mean on tyres?
There’s a simple way to check your tyre is an Audi Genuine Tyre: the ‘AO’ stamp, which stands for ‘Audi Only’. It means you can be confident these tyres have undergone over 50 separate performance tests and have been checked to much higher standards than statutory tyre regulations. For example, a tyre manufactured and designated with the AO (Audi VAG) coding, can be fitted across other vehicle brands without concern, The differences would be imperceptible and have no affect on wear or performance etc.There’s a simple way to check your tyre is an Audi Genuine Tyre: the ‘AO’ stamp, which stands for ‘Audi Only’.

Are 205 55 R16 tires suitable for winter driving?
When discussing winter tire performance, a tire size such as 205/55R16 provides several advantages: Improved Traction: A wider tire provides better traction on slippery road surfaces. The extra width gives you better control when driving on snow and ice. Similarly, we only recommend changing the aspect ratio by 5% either side of your cars preferred size. For example, a car designed to take a 60 aspect ratio tire could also fit a 55 or 65 aspect ratio. In winter it is very common to ‘downsize’ tires – this is making the width slightly smaller.
