Things That Matter While Buying New Tyres

20/03/2023

The majority of buyers decide to swap out their vehicle's worn tyres for new ones that are the same size and capacity. This makes a lot of sense because your automobile was built to operate well with the brand, size, and kind of tyres it was originally equipped with. Hence, installing an identical or closely related replacement set would retain the performance and safety your car was intended to provide. Also, it would be beneficial before you take the car for your Dunlop Tyres Northampton.

You must be aware of your car tyre size and speed rating in order to make an informed choice. You should also think about how many miles any potential new tyres will last (this is called tread wear). The sidewalls of the tyres that are now mounted on your car are printed with a lot of that information.

Also, it is accessible online, at tyre dealers, and in most owner's manuals. To ensure you have accurate information, we advise you to cross-check such sources.

Here's how to decipher the key information printed on the sidewalls of your tyres. In this case, 245/40R18 93W


Tyre Dimensions

You must know the correct size if you plan to replace your tyres with something equivalent. The standard method for expressing tyre size for cars and light trucks is a brief string of numbers and letters that looks like this (as shown in the above illustration): 245/40-R18. The first value represents the tyre's width in millimetres at its widest point.

Low-profile tyres, which are squat and used on sports cars and muscle cars, have aspect ratios of 30 to 40. SUVs and family sedans are 45 to 60 inches or taller. The last number in the series represents the inch-scale diameter of the wheel that the tyre needs to mount to. Almost all tyres made today are radial tyres, as indicated by the "R" in the tyre's designation.

Speed Rating

Moreover, tyres have a speed rating that describes both their potential performance as a whole and the fastest speed at which they can travel safely for a lengthy period of time. The speed rating of high-performance tyres is higher than that of conventional family sedans and SUVs. Your car's original tyres had a speed rating that matched to the top speed the vehicle could go along with a substantial safety buffer. The letter that usually follows the tyre size in the alpha-numeric code represents this speed rating. Maximum speed ranges for the letters L to Y range from 75 mph to more than 186 mph.

Data about tread wear

The tread-wear rating and tyre mileage warranty are two pieces of information that can be used to determine how many miles a set of tyres will last. The word "treadwear" is followed by a number on the tyre sidewall that represents the tread wear rating. The likelihood that the tyre will last further increases with this number. There's a lot of variation in this value due to the imprecise nature of the tests used to measure treadwear.

Examining the tread-life warranties offered by the manufacturers is a better way to estimate the prospective tyre life and compare the anticipated longevity of various tyres you may be considering. In addition to guarantees covering manufacturing quality and flaws, many tyres now have warranties covering tread life. You can get this information online or in the tyre manufacturer's promotional materials. According to the industry standard, approximately 75% of all drivers will discover that their tyres survive at least as long as the mileage specified in the tread life warranty. In most cases, you can get a credit for the % of miles you fell short of if your tyres run out before the promised mileage bogey, which you can then use to buy new tyres.

Run-flat Tyres

Many manufacturers come standard with run-flat tyres on their vehicles. These tyres have the ability to travel small distances at slower speeds even after being punctured, so you can get to your house or a repair shop without having to stop and change a flat. If your vehicle arrived with run-flat tyres, you can choose to switch them out for regular Buy Tyres in Northampton and have a spare on hand. Alternatively, you might buy a fresh pair of run flats to replace your worn ones. Furthermore, since tyre-pressure monitoring systems are now standard equipment for all new automobiles, you could even add run-flat tyres to a vehicle that didn't come with them.
