Drivers bothered by the noise output of their tires should purchase quietest tires that are available in the market if they want a quiet and comfortable driving experience. That said, here’s our list of the 2019 Top 10 Quietest Tires to give you some help in choosing your best tires. List appears in no particular order.
How do I find quiet tires for my car? Excess tire noise can be a real drag on your driving experience. At minimum, consistent tire noise is an annoyance. In extreme cases tire noise can disrupt conversations, and even give you a headache. Drivers who’ve experienced a noisy set of tires often put quietness high on their list of tire priorities.
Tire noise reduction is a science. Designers have figured out how to tune tread patterns to change the harmonics and disrupt air flow. There are sizing and rating considerations, too. Here’s what to look for to get quieter tires: Continuous, circumferential ribs with straight grooves in between.

Low rolling resistance tires are designed to reduce the energy loss as a tire rolls, decreasing the required rolling effort — and in the case of automotive applications, improving vehicle fuel efficiency. Approximately 5–15% of the fuel consumed by a typical car may be used to overcome rolling resistance. A 2003 California Energy Commission (CEC) preliminary study estimated that adoption of low-rolling resistance tires could save 1.5–4.5% of all gasoline consumption, but that current data were also insufficient to compare safety and other characteristics. A United States National Highway Traffic Safety Administration (NHTSA) study in 2009 found that if 2% of the replacement tires would reduce their rolling resistance by 5%, there would be 7.9 million gallons fuel and 76,000 metric tons of CO2 saved annually. (SAE J1269 and SAE J2452) performed on new tires.
A graph of the A-, B-, C- and D-weightings across the frequency range 10 Hz – 20 kHz Video illustrating A-weighting by analyzing a sine sweep (contains audio)A-weighting is the most commonly used of a family of curves defined in the International standard IEC 61672:2003 and various national standards relating to the measurement of sound pressure level. A-weighting is applied to instrument-measured sound levels in an effort to account for the relative loudness perceived by the human ear, as the ear is less sensitive to low audio frequencies. It is employed by arithmetically adding a table of values, listed by octave or third-octave bands, to the measured sound pressure levels in dB. The resulting octave band measurements are usually added (logarithmic method) to provide a single A-weighted value describing the sound; the units are written as dB(A). Other weighting sets of values – B, C, D and now Z – are discussed below.
EU Tyre Label The Tyre Label is a mark for motor vehicle tyres. Manufacturers of tyres for cars, light and heavy trucks must specify fuel consumption, wet grip and noise classification of every tyre sold in EU market starting in November 2012. For passenger car, light truck and truck tyres the information must be available in technical promotional literature (leaflets, brochures, etc.), including the manufacturer website For passenger and light truck tyres, the manufacturers or importers have the choice of either putting a sticker on the tyre tread or a label accompanying each delivery of batch of tyres to the dealer and to the end consumer The tyre label will use a classification from the best (green category "A") to the worst performance (red category "G"). This initiative results from a regulation by the EU Commission released in 2009. It is part of the Energy Efficiency Action Plan, designed to improve the energy performance of products, buildings and services to reduce energy consumption by 20% until 2020.
