How To Compare Tires (Ultimate Guide For Tire Buyers)

Regardless of the appearance of many faster transportations such as aircraft, trains, etc., cars still play an essential and irreplaceable vehicle since their inception in 1886. Because automobiles are widely used, individuals might encounter various problems. As a significant component of cars, tires also gain much attention. 

Usually, the car will last with various tires as they directly rub against the road surface. In other words, car owners will have to change tires regularly, and they may be concerned about how to compare tires. If it is also your case, read the text below for more information and clarification. The content below is illustrated with the most reasonable and understandable method to follow.

How To Compare Tires (Detailed Guide Tire Types)

The first thing to consider when it comes to comparing tires is knowing the exact type of tires suitable for your vehicles. As you may know, along with the variety of means of transportation, manufacturers have developed many different kinds of tires to fit them. 

Tire Types 

Generally speaking, you can not purchase a 10R22.5 size tire, which is used for buses, for your personal car. Therefore, being aware of the right tire is extremely important. Besides, it is common for users to choose similar or exact replacements. 

Another reason for this action is the belief that the car’s manufacturers have chosen the tire that best matches their products. There are several ways for you to detect the size of your previously used tire. 

However, the easiest method would be to look at the driver’s manual or the door placard. You will see a series of numbers and characters like 175/65R15 82H. Below illustrated way how to read it:

  • 175: The three first characters are the width of your tire. In this case, your tire is 175 millimetres wide.
  • 65: This is the height of the sidewall of your tire from wheel to tread, determined by a proportion of the width of the tire. The size of the sidewall continues as follows: 65 percent by 175 mm: 113,75 mm.
  • 15: This is just the diameter in inches of your wheel.
  • 82H: The three final characters include two elements: the number 82 and the letter H. Here the 82 pertains to the maximum air pressure the tire can hold, whereas the H in this example illustrates the tire’s speed.

Most new tires have a treadwear grade, which is an instrument for comparison. The common mistaken perception is that treadwear presents how long a tire may survive for thousands of kilometres. However, it is not the case. 

Typically, producers utilize various methods to generate claims for treadwear mileage, making it challenging to compare kilometres of tires among tire brands.


For a better understanding of treadwear, you should refer to consumer reports. Simply speaking, these documents provide a comparison of the kilometric images of the tire in the rating chart, which offers the predicted all-season kilometres and all-season performance automobile pipes. 

But, of course, the forecast mileage depends on the thorough tests carried around the clock, over 1,000 miles a day.

Tire Pressure Monitoring Systems 

Since its first introduction in 2008, the TPMS, short for tire pressure monitoring systems, has become the most well-known and widely-applied standard equipment for almost all new automobiles. 

Since then, governments in many nations have devoted themselves to conducting studies checking the effectiveness and efficiency of TPMS. Consequently, the result reveals that the application of this system leads to substantial cuts in underinflated road tires, which improve fuel-saving and safety.

Following the Federal mandate, the vehicle can monitor and notify the driver when the pressure drops remarkably. Although the detailed technology is not specified, many users are satisfied with this innovation. 

Nowadays, more and more cars’ wheels are equipped with pressure monitoring sensors to communicate the data wirelessly to the automobile’s instrument panel, known as direct TPMS. 

When implementing this system, the primary concern of users and also the significant drawback would be the amount of energy consumed. To be specific, using these systems requires battery replacement after several years, leading to the replacement of the entire sensor.

On the other hand, an indirect system assesses the wheel’s speed and interprets the pressure using anti-locking braking systems. However, these systems do not use the forces, and so the pressure cannot be displayed.

How to Read a Tire Sidewall 

It is common for regular users to ignore or not know the characters’ appearance on the tire sidewall. Nevertheless, after reading this article, you should realize that sidewall can reveal more than you can imagine about your car’s tires. 


Locating in the centre with the ideal size is the information about the tire’s size. As mentioned before, you can see the series like 175/65R15 82H represents the width in millimeters, ratio of height to width, maximum pressure that can be held, and tire speed, respectively.

Load Index

This figure is illustrated after the size series. Simply speaking, it is the weight each tire can endure without being damaged. For example, 94 means 1477 pounds per tire, which is typical for a medium-sized pneumatic vehicle.

Rating of Speed

This is the letter right after the load index indicating the top speed of the tire while the load index is being carried. Usually, you will find T (118 mph) and H  (130 mph) in a private car. 

Besides, there are some cars with higher figures like V (149 mph), ZR (149-plus mph), W (168 mph), and Y (186 mph). In addition, winter tires may carry the designation R (106 mph) or higher.

How to Read a Tire Sidewall 

Treadwear grade

Generally, you will find the exact term “ Treadwear” accompanied by a number in the car’s sidewall. This figure mandated by the government indicates the predicted wear of a tire. For example, if your number is 300, it means that your tire will wear three times and a tire graded 100.

Traction and temperature scores

These values indicate the capacity of the pneumatic to stop wet and resist temperature. The ratings range from A (best) to C for temperature resistance. To be specific, AA is the most remarkable for traction, and C is the poorest for traction.

Manufacture date code

Like regular products, the tire also has a Transportation Department number after the sidewall lettering. For example, figure 2321 means the tire was manufactured in the 23rd week of 2021. Remember that tires the older the tire becomes, the more low-quality it is.

Tire Maintenance 

As a car owner, your biggest concern would be how to keep tires last as long as possible. Doing this saves not only your account but also your time devoted to purchasing tires. 

Nowadays, tires can survive up to 50,000 miles or even more after being affected by environmental factors such as heat, weather, rocks, etc. 

It is impossible to avoid these external factors. However, there are some ways you can apply to lengthen the lifespan of tires as follows:

Test air pressure monthly

This step must be done before your car reaches more than a couple of miles and when the tires are cold. First, make sure they are inflated by the air pressure on the door jam or within the fuel filling or glove compartment. Don’t push the sidewall of a tire; this is the maximal tire pressure.

Search for uneven tread wear

This demonstrates low wheel alignment and damaged suspension parts. Moreover, when purchasing an entirely new tire, you should also check the alignment and suspension. 

Be careful with a weight capacity

Each vehicle is manufactured with its own ability to carry weight. To be specific, it is the amount your vehicle can handle but still function effectively. If you force your tires to deal with weight exceeding this limit for a long time, your tire and even your car will likely become ruined soon.  

Rorate tires periodically

Doing this allows you to extend the tire’s lifespan and even performance. According to many car manufacturers, it is highly recommended that you rotate tires every 10,000 kilometres or six months. 

Balance your tires

Unbalanced tires can cause fast and early wear. Therefore, be careful whenever you rotate, change or touch tires, make sure they are well-adjusted and balanced. 

Inspect tires frequently

Using the car and leaving it to function without testing is a typical mistake car owners usually make. As a precise user, never commit this fault because it is the fastest way to destroy vehicles. 

You can set up a schedule and regularly inspect your car tires to detect cracks, cuts, and bulges on the sidewall and treadwear. 

Change tires according to the season

In some nations, there are considerable differences caused by weather that require people and things to adapt, especially those with distinguished summer and winter periods. 

Car developers in those countries will offer summer and winter tires suitable for them. You might wear your tires faster than intended by using winter tires in summer or vice versa.

Tire Brands 

As long as the car, there are more and more brands aiming at developing tires only. Below are some great companies you can consider when intending to purchase new tires:


Since its introduction, Bridgestone has developed remarkably and become one of the world’s three most prominent makers of tires with its head office in Tokyo. Its tire operations are based in Nashville, Tenn. 

Previously, Bridgestone had superior strength and outstanding ability in producing winter tires, and now it is introducing a replacement run-flat tire line called DriveGuard. 

The Alliance Tire Company Ltd

This firm produces and markets tires for agricultural, multi-purpose, and industrial customers in Europe, the USA, Japan, and Latin America in Mumbai, India. 

It is based in Hadera (Israel) and has three production units in Tirunelveli and Dahej (India), and since 2016 is owned by Yokohama Rubber Company.


The Indian multinational tire production business Apollo Tyres Limited is based in Gurugram, Haryana. It was founded in 1972 and its first facility was in the Thrissur district. 

With tremendous development, the business presently has five production plants in India, one in Hungary, and one in the Netherlands. Recently, Apollo has stated that it will be entering the two-wheel tire sector and aim more at the European market. 

Wrapping Up

In conclusion, to learn how to compare tires correctly, you should consider specific aspects such as the size, the season, etc. Among those illustrated above, you should prioritize some according to your specific situation to choose the best suitable tires for your car. Besides, hopefully, you could also acquire helpful knowledge about tires.
