Tire numbers

Before knowing more about tires, you should have a clear idea about tire numbers. Tire numbers are very complex to see, but every character has a different meaning. We will try to explain the tire number with the “P 205/55 R 16 91S” tire. The meaning of the number is given below. 

i. Tire type

The first one or two characters are used to indicate the tire type. There are three types of tires. The types are P, LT, and ST. The P-type means passenger vehicle tire. The LT stands for light truck tire and the ST means special trailer tire. The P-type tires are used in smaller cars like private cars and SUVs. The LT tires are used in trucks or buses which carry more weight than P-type. The ST tires are used in trailers. These are the most weight-carrying capable tires. 

ii. Width

The three-digit after the first characters mention the width of the tire. The inscribed number of width is actually in the millimeter unit. 

iii. Aspect ratio

After the width, There is a forward slash that separates the aspect ratio from the width of the tire. An aspect ratio is a percentage number. It means the percentage of sidewall height according to the width of the tire. The height of the sidewall increases with the ratio. 

iv. Construction type

The letter after the aspect ratio indicates the construction type of the tire. Construction type is the internal material of the tire. There are two construction types. They are R and D construction types. R stands for radial construction type and D means diagonal or bias construction type. The radial tires have a better grip on the road and good mileage. Most of the tires are radial tires. 

v. Wheel diameter

The number next to the construction type indicates the diameter of the wheel. The unit that is used to measure the wheel diameter is in inches.  

Can I use 205 instead of 215?

You can have a 205 tire in the place of a 215 if you want a thin tire. If you are using a 215 tire then the space for your tire is bigger than a 205 tire because the height of the sidewall decreases with the width.

That is why if you use 205 tires instead of 215 it will not be looking good but it will do the work. Besides, the meter will not show the perfect mileage because the speedometer is actually set up according to the default wheel. If you can accept these problems you can use a 205 tire instead of a 215 tire.

What is the difference between 205/75 R14 and 215/75 R14

There are some differences between the two tires. From the tire numbering system, we know that the first three digits are the indicator of the width of the tire. That means the first tire has a 205-millimeter wide tire and the second tire has a 215-millimeter wide tire.

Thus, the second tire is 10 millimeters wider than the first tire. Apparently, the rest of the numbers and characters seem to be the same but there are differences between both. As the aspect ratio is dependent on the width of the tire, the 215 tires are taller than the 205 tires. The R of the numbering system means that both of the tires are made of the same material. Both of the tires are radial tires.

The last two-digit number indicates the wheel diameter. The rim diameter of the wheel is 14 inches. However, the whole tire diameter changes because of the height of the sidewall. The main differences between the two tires are width and height. Here are good samples of 205/75 R14 and 215/75 R14 tires. The difference between the two tires is given in the table below.
