Everything You Need to Know Before Buying New Tyres

July 16, 2021

Just like other purchases, dozens of tyre manufacturers make tyre 'shopping' a little overwhelming. The varying tyre sizes, types, specifications, and brands make deciding which one to pick tiring – pun not intended..

However, tyres are considered the most critical safety feature of every vehicle. Depending on the supplier and manufacturer, getting a replacement takes time and a considerable budget. Nonetheless, tyres cannot afford to be a misfit. Otherwise, you'll find yourself in between what Karina Wolfin, CEO of Direct Appliance Rentals, said, "a heart-fluttering near-miss and a heart-breaking disaster."

Take out the headache of figuring out what's the best tyre for your car. Here, we have simplified a guide to walk you through everything you need to know before buying new tyres. 

When To Replace Your Tyres?

When the tyre wear indicators show that the tyre has worn out, it's time to buy another. These indicators are a built-in safety feature and could easily be identified as small squares in the tread's more prominent grooves.

Immediately replace the tyres when the face has worn down at this point or when any deep cuts, bulges, protrusions, exposed cords, and any damages have been observed. It is important to note that tyres must be replaced by a set including the spare or group of two - either rear or front.

What To Check Before Buying A New Tyre? 

Here's what you need to consider in buying a new tyre:

Tyre Type Compatibility

Choose tyres that are compatible with your vehicle or your use of preference. You may also check the vehicle manual to see which tyre type is suitable. Typically, you can find the tyre's specifications on its sidewall. They usually look like this —P175/65R16 84V.

Tyre Section Width

In this example, P175/65R16 84V, the letter indicates the vehicle style – P (Passenger and most 4WD), LT (Light Truck), M (Motorcycle), ST (Special Trailer), and T (Temporary).

The following number, which is 175, is the section width. The section width is the distance between the exterior walls of the tyre. It's indicated in millimetres and is the size of the tyre when fitted to the rim.

Profile/ Aspect Ratio 

The second number, which is 65, is the tyre profile or aspect ratio—the section width to section height, expressed in percentage. In the example given, the tyre has a profile of 65%. Note that section height is the distance between the top of the tyre and the wheel bead seat and that tyres with a lower aspect ratio generally have a firmer sidewall and are used on race cars.

Construction 

Tyre construction is indicated by a letter, R (Radial), which is the most common for passenger car tyres. While D stands for Diagonal or "Bias", which is effective in machinery used in terminals and ports, B is Belted-Bias ply used in trailers.

Diameter 

The number right after the tyre construction indicates the diameter (in inches) of the rim that the tyre is designed to fit. The diameter in the given example is 16 inches.

Load Rating

Load ratings are expressed in index numbers with the corresponding value in kilograms. It is the maximum weight that a correctly inflated tyre can withstand. In the given example, the load rating is 84 (500 kg). Other samples of load ratings are 82 (475kg), 86 (530kg), 89 (580kg), 92 (630kg), and 94 (670kg).

Speed Rating

The last letter indicates the tyre speed rating. It is the maximum speed that the tyre can travel for ten minutes without breaking. This detail is crucial since every vehicle owner is obliged to select tyres with the correct speed rating. In the given example, the speed rating is V which is 240 km/h. Other examples are M (130 km/h), S (180km/h), T (190km/h), H (210km/h), and W (270km/h).

Consider Your Local Climate

Most cars are equipped with all-season general-purpose tyres. But what if the winter season is longer in your area? Winter tyres are designed for more robust traction on slippery roads. They have shorter braking distances on ice and snow.

Summer tyres are also more effective during the hot season. It might be a better practice to alternate sets of summer and winter tyres for safer travel.
