How to choose the right tires for your car

We have already figured out how to choose the right wheels for the car. Now our task is to pick up the tires. Markings on the sidewall of the tires are probably no less than the parameters of the disk, but in General, it is somewhat easier to choose a tire. Find out what numbers like “185/70 R14 88H” mean, and how to deal with them.

 

WHAT TIRE PARAMETERS SHOULD BE CONSIDERED WHEN PURCHASING?

SEASONALITY

Seasonality is an obvious parameter: at the time of choosing a rubber, you know perfectly well whether you need winter or summer tires, ir you need to find trailer tires then you need to watch some trailer tire reviews, Helcules trailer tires are one of the best on the market right now.. The question of choosing the so-called ” all-season “rubber and its applicability in the conditions of year – round operation is a topic for a separate conversation, as well as the choice of mud or”universal”. Here it is only necessary to say that winter tires should be marked with the “snowflakes” icon or the letters ” M+S “or” M. S”.

 

TREAD TYPE

In General, the tread pattern structure is symmetrical or asymmetric, as well as directional or non-directional. Symmetrical non-directional tread is the simplest basic type of pattern: these tires are the most common and inexpensive. The orientation of the tread primarily increases its ability to effectively remove water from the contact spot-this reduces the risk of aquaplaning. Well, the asymmetric tread pattern is designed to combine good drainage and directional stability. The issue of choosing a projector drawing also deserves a separate conversation.

 

TYPE OF TIRE CONSTRUCTION – CHAMBER OR TUBELESS

By their design, tires can be designed for use with or without a camera. However, in modern conditions, the choice of tire design is almost predetermined: almost all modern passenger tires are tubeless. These tires are marked with the words “Tubeless” (meaning “tubeless”) or “TL”.

 

TYPE OF CORD CONSTRUCTION

The type of construction of the cord-the power part of the tire, its “skeleton” – is also a characteristic that does not require much attention when choosing modern tires: almost all of them today are radial. This fact is indicated by the same letter ” R “in the tire marking: for example, the mark” 185/70 R14 88H “means that this is a radial tire with a landing diameter of 14 inches, and not a” radius ” of 14 inches, as is often mistakenly said and believed.

 

MOUNTING (OR LANDING) DIAMETER

This is also a simple parameter if you already have disks for which you choose tires: the landing diameter of the tire must match the diameter of the vehicle. If you choose wheels together with tires, you need to specify in the operating manual what diameter disks are acceptable for use on your model, and then select tires of the same size for them.

 

BUS WIDTH

The width of the tire is the first numeric index shown in the tire label. It is specified in millimeters: the 185/70 R14 tire has a width of 185 millimeters. This is probably the first parameter from our list that can vary when choosing a tire for a particular disk or car.

 

SECTION HEIGHT

The height of the profile or series, the second index measured in the tire marking. It is specified as a percentage of the tire width: in other words, this is the ratio of the profile height to width as a percentage. For example, the 185/70 R14 88H tire has a profile height of 70% of its width. It is easy to calculate the height in millimeters: you need to multiply the width by the profile and divide by 100 – for our tires, this figure is 129.5 millimeters.

 

LOAD INDEX

Load index-a parameter that reflects the maximum allowable load on the tire during its operation. It is indicated by a numeric index, indicated after the geometric parameters of the tire: for example, our conventional tire 185/70 R14 88H has a load index of 88. The index can be found in the table provided by the tire manufacturer – in our case, the index 88 means the permissible load of 560 kilograms. When choosing tires, you should keep in mind that the maximum allowed weight of the car, respectively, should not exceed the maximum load index multiplied by 4 — the number of tires on the car.
