Why is the Right Tyre Choice Critical and Easy?

by admin

Although many people can never pay enough attention to the tyres, wheels, or tyres of their vehicles, tyres are the most important aspect of the vehicle. That’s the only explanation why a vehicle can drive. While you can create fantastic engines or highways, it’s the tyres that link the car to the ground. As critical as they are, people usually spend the least amount of time choosing the right tyres for their vehicles. Via this post, we are going to help you pick tyres to get the best value out of them.

One does not know that, but the tyres impact almost every part of a vehicle. Breaking, acceleration, handling, ride efficiency, suspension, and even fuel consumption are affected by the tyres. But it’s only fair to learn a few basics to hold in mind when adjusting the car’s tyres.

What do the numbers and alphabets of your tyre mean?

The notations in the picture below can initially confuse you but don’t worry, we’ve protected you. You will be able to understand how easy it is to decipher after reading this post. Let’s go over it one by one!

Here, the diameter of the face of the tyre is 205 mm. This reflects how much land is in contact with the earth. The broader the face, the stronger the grip and the wider the area in contact with the road. When you walk around the corner, handling performance and stability can depend largely on how much traction you have on the surface, which, in essence, is the product of how much area of the tyre is in contact with the road. The diameter of the tyre specifically impacts the handling of the car.

55 represents the height of the sidewall of the tyre, the proportion of the width of the tyre. In our situation, 55 percent of 205 is 113 mm. The higher the sidewall of the tyre, the more rubber it has and, therefore, the greater the bump-absorption characteristics. The height of the sidewall is also closely related to the efficiency of the car’s journey.

R stands for Radial, which means that the steel wires inside the tyres are 90 degrees to the top of the rubber. Generally speaking, today all passenger vehicles come with radial tyres.

The size of the wheel is shown by 16 inches.

91 is a load index for a tyre. This is very significant since it reflects the highest weight a tyre can bear to work comfortably and smoothly. The load index starts from 20 and goes all the way to 99. However, the table below shows some of the typical load indices used in a variety of vehicles for comparison purposes.

Load Index Weight (kg) Load Index Weight (kg)
70 335 79 437
71 345 80 450
72 355 81 462
73 365 82 475
74 375 83 487
75 387 84 500
76 400 85 515
77 412 86 530
78 425 87 545

V is the speed index of the tyre. Similar to the load index, each tyre is optimised for the highest speed at which it can operate safely and smoothly. The table below displays the speed indexes used by different vehicles.

Speed Index Max Speed (km/h) Speed Index Max Speed (km/h)
K 110 T 190
L 120 U 200
M 130 H 210
N 140 V 240
P 150 (V) >240
Q 160 W 270
R 170 (W) >270
S 180 Y 300

High and medium profile tyres

Tyres can also be graded as high-and low-profile tyres, and can also be found in different situations and vehicles.

Performance car

Performance vehicles use low-profile tyres, which means that the diameter of the tyre is going to be very high and the sidewall is not going to be as high. For eg, the BMW M5 Competition uses 285/35 R20 rear tyres. The explanation for this is clear. A performance car is designed to accelerate faster and travel around the corners at very high speeds. The thickness of the face of the tyre is also of utmost importance. This ensures a lot of road grip for easier handling.

SUV’s

SUVs are used to go off-road where the highways are not paved. There’s going to be a lot of potholes and undulations on the lane. The primary criteria are the standard of travel to ensure the safety of passengers. Therefore, high-profile tyres are used in this case. Jeep Wrangler uses 255/75 R17 tyres, for example. This means that the sidewall of the tyre is going to be very high to withstand all the bumps and undulations of the lane, offering passengers a lot of ease.

Regular cars

Regular vehicles that people use for a daily trip usually aim to find a balance between high and low-profile tyres. It is important to ensure the consistency of the ride as well as the decent handling characteristics for daily usage.
