Car Tyre Size Details – Explaining Tire Sizing Methods
Car tyre size is the measurement of a car tyre’s width, height, diameter, and load index. The load index is a number that corresponds to the maximum weight that the tyre can support when inflated to its maximum pressure. The higher the load index number, the greater the weight that the tyre can support.
The width of a car tyre is measured in millimetres (mm), while the height and diameter are both measured in inches. tyres with a larger width provide a better grip on wet or icy roads, but they also create more road noise and may make your car feel less stable at high speeds.

How to Read Tyre Size
When you’re ready to buy new tyres, you need to know how to read tyre size so that you can make sure you’re getting the right ones for your car. Tyre size is made up of a series of numbers and letters that tell you the width, height, diameter and load rating of the tyre.
The first number is the width of the tyre in millimetres.
The second number is the height of the sidewall as a percentage of the width. The third number is the diameter of the wheel in inches. The fourth number is the load rating or maximum weight capacity of the tyre.
To give an example, a tyre with the size 245/40R18 would have a width of 245mm, a sidewall height of 40% of that (98mm), a 18-inch diameter wheel and a maximum weight capacity of 880kg. Now that you know how to read tyre size, it’s time to start shopping for new tyres! Be sure to consult your vehicle’s owner manual or ask a professional at your local tire shop to find out which sizes are recommended for your specific car model.
Wheel And Tyre Sizes Explained
When it comes to wheels and tyres, there are a lot of numbers and letters that can be quite confusing. In this blog post, we will explain what all of the numbers and letters mean when it comes to wheel and tyre sizes. The first number that you will see is the width of the tyre in millimetres.
The second number is the height of the sidewall as a percentage of the width. The third number is the diameter of the wheel in inches. For example, a common size for passenger cars is 195/65 R15.
This means that the width of the tyre is 195mm, the height of the sidewall is 65% of the width (130mm), and the diameter of the wheel is 15 inches. The letter at the end indicates the type of construction used forthe tyre. “R” stands for radial, which is by farthe most common type these days. You may also see “D” for diagonal or “B”for bias-ply tyres, but these are mostly found on older vehicles.
Tyre Profile Explained
There are a few things to consider when purchasing tyres for your vehicle, and one of those is the tyre profile. The tyre profile is the measurement of the height of the tyre sidewall, and it can have an affect on a number of things, such as grip, handling, fuel economy and more. Here’s everything you need to know about tyre profiles.
The first thing to understand is that there are two different types of tyres on the market – low profile tyres and high profile tyres. Low profile tyres have a shorter sidewall height, which means they provide less cushioning and shock absorption than high profile tyres. This can lead to a harsher ride, but it also results in improved grip and handling.
High profile tyres have a taller sidewall height, which means they provide more cushioning and shock absorption than low profile tyres. This can lead to a smoother ride, but it can also result in reduced grip and handling. So, which type of tyre should you choose?
It depends on your driving style and needs. If you’re looking for the best possible performance from your vehicle, then low profile tyres are generally the way to go. However, if you’re looking for a smoother ride or live in an area with lots of potholes or other road hazards, then high profile tyres might be a better option for you.
When it comes to choosing new tyres for your vehicle, make sure you take the time to understand tyre profiles so that you can make the best decision for your driving needs.
Tyre Aspect Ratio
The tyre aspect ratio is the height of a tyre’s sidewall expressed as a percentage of its width. The lower the aspect ratio, the shorter the sidewall and the wider the tyre. The higher the aspect ratio, the taller the sidewall and the narrower the tyre.
The tyres on most cars have an aspect ratio between 60 and 70. This means that if your car’s tyres are 225mm wide, their sidewalls will be between 135mm and 157.5mm tall. Aspect ratios have a direct effect on a number of factors including comfort, handling, grip and fuel economy.
In general, tyres with shorter sidewalls will offer better handling and grip, while those with taller sidewalls will be more comfortable but may sacrifice some performance. Fuel economy is also affected by tyre choice – in general, wider tyres are less efficient than narrower ones as they create more rolling resistance. However, this needs to be balanced against grip levels – if you’re regularly driving in wet or icy conditions, it’s worth sacrificing some efficiency for increased safety.
How Do You Read Your Tyre Size?
When you’re looking at your tyre, you’ll notice a series of numbers and letters running around the edge. This is called the tyre size, and it’s there to tell you all sorts of useful things about the tyre. Here’s a quick guide to reading your tyres size so that you can make sure you’re getting the right ones for your car.
The first thing you need to look at is the width of the tyre. This is represented by a number, and it tells you how wide the tyre is from sidewall to sidewall. The next number is the aspect ratio, which tells you the height of the tyre compared to its width.
A higher aspect ratio means a taller tyre, while a lower ratio means a wider tyre. After that, you’ve got two more numbers that are important for understanding your tyres size. The first one is the diameter of the wheel that this tyres will fit onto.
The second is load index, which gives you an idea of how much weight each tyred can carry safely. Finally, there’s a letter code at the end of all this which tells you whether this is a summer or winter tyres (or sometimes all-season). S means summer and T means winter. Now that you know how to read your tyres size, go forth and buy some new ones!
What is the Tyre Size for My Car?
There is no definitive answer to this question as the tyre size for a car can vary depending on the make and model of the vehicle. However, there are some general guidelines that can be followed in order to determine what size tyres are suitable for a particular car.
If you are unsure about what size tyres are appropriate for your car, it is always best to consult with the manufacturer or a qualified mechanic.
They will be able to advise you on the correct tyre size based on the make and model of your car. In general, most passenger cars will require tyres that have a width of 185mm-225mm. The width of the tyre is usually indicated on the sidewall of the tyre, so it should be easy to identify.
The height (or profile) of the tyre is also important and this is usually expressed as a percentage of the width e.g. 50% = 125mm high. Again, this information can be found on the sidewall of the tyre. The diameter of the wheel rim is also something that needs to be taken into account when selecting tyres.
The most common sizes for passenger cars are 14 inches and 15 inches, but there are other sizes available too e.g. 16 inches and 17 inches.
How are Tyre Sizes Written?
When it comes to tyres, there are a few different ways that sizes can be written. The most common way is by width, aspect ratio and diameter, all in millimetres. For example, a tyre size might be written as 205/55 R16 91V.
This reads as follows:
- The width of the tyre is 205mm.
- The height of the tyre (as a percentage of the width) is 55%.
- So, the height of this particular tyre would be 113mm. – The diameter of the wheel that this tyre can be fitted to is 16 inches, or 406mm. – The load index is 91 – meaning that this particular tyre can carry up to 615kg per tyre.
- The speed rating is V -meaning that this tyre can safely handle speeds up to 240km/h.
What are Tyre Size Numbers?
The tyre size number is the width of the tyre in millimetres. The first number is the width of the tyre, and the second number is the height of the tyre. For example, a 215/60 R16 tyre would be215 mm wide and 60 mm tall.
The “R” in this case stands for “radial”, which means that the tyre has steel or nylon cords running from bead to bead, perpendicular to the tread. The 16 indicates that this is a 16-inch wheel.
Car tyres are an essential part of a car, and so it is important to know the different tyre sizes. There are three main types of car tyres: passenger, light truck and heavy truck. The size of the tyre is represented by a series of numbers and letters.
The first number is the width of the tyre in millimetres, while the second number is the height of the sidewall as a percentage of the width. The third letter denotes the type of construction used in the tyre. For example, a 225/50R16 91V tyre would be suitable for a passenger car.
The width of this tyre would be 225mm, while the sidewall height would be 50% of that, or 112.5mm. The R16 indicates that this is a radial tyre with 16 inches diameter, while 91V means that it has a load index rating of 91 and a speed rating of V (for up to 240km/h).
