When you have a car or an SUV, the driving comfort can definitely be impacted by what tyres you have and the condition of the tyres. Wheel alignment and the balancing of the tyres are important to ensure that the vehicle can roll smoothly without any vibrations due to misalignment. If you feel that the steering wheel is rattling when you drive at high speeds, then you have some issues with balancing or your wheel alignment needs to be looked at at a service station.
When you purchase new tyres you will see that there is a label nowadays on all the tyres, on it you have 3 different indicators of how well the tyres perform on wet grip, rolling resistance and rolling noise. A high rolling noise can impact your driving comfort, as you will hear the tyre noise inside the coupe. If you have a hybrid or an electric car, this can be quite significant, as you don’t have loud noise from the combustion engine. You can use the tyre label to select a tyre that has a low noise level. There are even tyres where the noise level can be damaging for long exposures to the noise level. Summer tyres tend to have a lower rolling noise than winter tyres, especially if they are studded. However as you can see on the tyre label, the studded tyres are not as noisy as one might think.
The last thing you want when you consciously buy a very comfortable car is to have things negatively impacting it. Shock absorbers is another item that can impact the driving comfort, as bad shocks can make the ride very bumpy and make the car to sway. It also impacts negatively the braking distance as the shocks also push the tyres against the road surface.
Tyre pressure is also important for driving comfort. A car needs to have tyres with the correct inflation pressure. If the pressure is low the rolling resistance will increase, which can impact the tyre noise. You also have increase in the tyre wear and the car will start consuming more fuel as you drive. This might not impact the driving comfort, but it negatively impacts the driving economy of the car, so don’t waste money that could better be spend on something nice.
