Low profile tyres have been increasing in popularity – from both the aesthetic and performance perspectives.
There are some common benefits of changing from standard profile tyres to low profiles – including improved dry handling, cornering ability and increased steering response.
Low profile tyres have a shorter sidewall – or a lower aspect ratio than normal tyres. Low profiles also have larger tread blocks, a stiffer and wider apex – and they can be made from specialised compounds. Tyres with a 50 aspect or less are considered to be low profiles.
Low profile tyres require a large amount of engineering – tuning a specific car for a particular tyre, tuning that type of tyre. Things that can be tuned or engineered include the chemistry of the rubber, the belt height, the tread depths.
Today, there are many vehicles that come with two or three tyre sizes available across the different models within the range. Tyres will change the ride comfort of your car. The tyres, the suspension and the seat cushion are all elements that contribute towards your ride comfort. When the tyre profile goes down, it impacts or changes your ride’s comfort – low profile tyre rides are harder.
Whether you are choosing to opt for low profile tyres on a new car or fit them after purchase, there are pros and cons. Low profile tyres increase the contact area between the tyre and the road – which assists in braking and handling.
Low profile tyres also have many cons – including being expensive, easy to damage and they can be noisy.
