It's time to buy a winter tire. I want tires that are marked - very good, fuel efficient, quiet and can ride in the rain.
In that case, we should have offered summer tires for winter conditions.
Fuel economy - the lower the resistance, the more economical the tire. (In winter, the opposite is necessary - keeping the tire on the road.)
Noise level - if we look at the studded tires, then only the studs will make noise, and if we take into account the permeability in the snow and slush, then the difference between the tread pattern is larger and it also creates additional noise.
Also, the noise level of 69db or 72db cannot be viewed. There is also a lot of fuss about the car itself. What is the upholstery of the cabin, etc.
However, 72db can be much quieter than 69db because the measurements are made according to certain parameters and conditions.
On different road surfaces have different noise levels. A tire with a lower decibel does not provide any advantage. The more frequently used road surface must be taken into account, in which case the softness of the tire and the mixture must be observed.
Tire labeling is what it means
