1) The tyre’s width is in millimetres.
2) In proportion to the breadth, the sidewall’s proportion of height.
There are three ways to do this:
4) The diameter of the rim.
5) Retrieve the index (the max load of the tyre).
Indicator of speed (the max speed of the tyre).
On the sidewalls, you’ll discover further details. However, they have no bearing on tyre sizing. In our essay on tyre markings, we go into great length on the significance of the letters and numbers that appear on the sidewalls of the tyre.

Meanings Of Tyre Size
So here is what those numerals and indications on the sidewall mean and how to decipher them: :
Type Of Tyre
The kind of tyre is in view by the first character of the code.
A commercial vehicle tyre is in refer to as a P-type. Automobiles, sport utility vehicles, crossovers, minibuses, and light trucks with P-class tyres are all included in this category.
For cars capable of hauling big loads, pulling trailers, or just needing an extra-heavy-duty tyre alternative, LT stands for light truck tyre. Three-quarter or 1-ton vehicles and SUVs are typically outfitted with them.
Special Trailer is the acronym for ST. Motor homes, fifth wheels, boat trailers, and multipurpose trailers all use these tyre sizes.
It’s typically known as a European size if there is no symbol before the first digit. In millimetres, it’s the same as a P or LT tyre, although its load capability may change.
Width Of The Tyre
The tyre width (measured from sideways, with the tire’s head on) is represented by the three-digit number after the letter. The section width is another name for this measurement.
The Aspect Ratio
Tyre width is separated from the two-digit aspect ratio by a forward slash in the tyre width number. There’s a correlation between the tyre aspect ratio and its “style,” as it’s commonly referred to.
Tyre sidewalls display the aspect ratio as a proportion. Tyre width divided by sidewall height, given as a percentage to get this measurement.
As you can see, the sidewalls is 65 per cent as tall as the tyre, illustrating the screen resolution. The sidewall elevation is determined by converting the 215 mm tyre width to inches (8.46). To get the final result, multiply it by a factor of 65. (.65). Sidewall elevation in inches is 5.5 as a result.
Everything you need to know about a tyre interior structure may be in just one letter.
Radial tyres, which are now the industry norm, are in view by the letter R. Compared to earlier generations of tyres, these tyres provide superior road grip, reduced rolling resistance for improved gas efficiency, ride comfort, and longer tread life.
D stands for bias-construction tyres. Which are tyres with diagonal (crisscross) plies. Normal, x-ply, or cross-ply tyres are also this kind of tyre. This internal structure is still in use in certain motorcycle and trailer tyres.
After the gap, the tyre load index is shown by a two-digit or three-digit number The commonly used evaluation chart is used to calculate the load index symbol’s meaning. 89 is the load index in our case, which means the tyre can support 1,279 pounds when filled to its maximum air pressure.
A Rating Of The Speed
Final but not least, the tyre speed rating is the last character. You may safely travel at this maximum speed for an extended period of time. High-speed tyres can tolerate heat better and give greater control while travelling at higher rates. Vehicles can only go as fast as the lowest-rated tyres on them.
