67dB Quietest tyres

The quietest 255/40 R20 tyres are labelled at 67 dB external noise:

Label values come from the EU EPREL database and apply to the EU market versions of each tyre. Wet grip and rolling resistance run from class A (best) to E; noise is the measured drive-by figure. A good label is a floor, not a verdict - the tests and owner ratings above tell you far more.

Michelin Pilot Sport 4 255/40 R20 2,485 miles October 21, 2026

The tyres have no flank protection, which is a disadvantage for high-quality rims. They are quiet, but without any damping in terms of comfort; every bump in the road feels like a hard impact, which surprises me since the car has air suspension - it probably has to do with the AMG sport suspension. The tyres are from 2020. More wear on the front than the rear (285/35/ZR20104Y) and that with a power distribution of 33/66.

Petlas Velox Sport PT741 255/40 R20 Audi A6 Avant 2.0TDI 52,000 miles September 15, 2026

Brought the A6 avant 2 years ago from a dealership. These tyres had just been fitted along with new brakes etc. I do above average mileage, around 24k a year with a mixture of roads but mainly motorway/ dual carriage way.
I’ve now done 52k on these tyres and I’ve just noticed this week that the handling in the wet has gone. But they were brilliant in standing water and heavy rain. These tyres are really quiet with the windows up, no road noise. Fuel efficiency, well as mentioned above I average in an Audi A6 Avant 2.0 TDI 2021 55mpg
850 mile to 70 litres of fuel.
Comfort levels - unfortunately its on sports suspension therefore quite a stiff ride.
However re the UKs influx in potholes these tyres have stood the time well.

Living on the Scottish west I and with an Audi Quattro I used to have a summer and winter tyre set, but decided to give these a try and have never looked back. So much so I also have since had them fitted to my kids cars.

Yokohama Advan Neova AD09 255/40 R20 Nissan GT R 3,000 miles July 1, 2026
Sensational tyres. Sidewalls are hard for a road focused semi slick tyre which helps steering and road feel. They work well from cold and get better when hot. Not particularly noisy or uncomfortable.

The wear seems ok because the gtr is a heavy car and wears it's tyres fairly quick. These are wearing slightly quicker than the PS4S I had before but I have journeyed to the ring and back in 41 degrees weather.

I think the nissan hides a lot of the weak points on wet grip but it's mostly ok until the water is deep and then it does aquaplane easily but not as bad as ar1 or ao52.

I'd recommend these for any driver focused daily driver and definitely track use.

Michelin Pilot Sport EV 255/40 R20 Hyundai 55,000 miles June 2, 2026
I have a full set of these tyres on my Ioniq 5 and they are brilliant I am very tempted to buy the same replacement tyres as they have been going so well. I have currently covered 55,000 miles and have 2.6 mm left on the most worn tyre. The other three all have 3.6 mmm who said EVs wear tyres heavily? I would say my driving. style was fast and spirited with a trip to North Coast 500
The only reason I would buy anything different is they could be quieter although this is only on paper as I haven't tried a different set on this car. Side walls are starting to crack the tyres are now four years old. Treadwear indicator states 200.

Michelin Pilot Sport 4 S 255/40 R20 Audi A6 15,000 miles April 4, 2026
I’ve previously used the Continental Procontact and the PilotSport 4 A/S and this has the best grip, handling, and feedback of them all. The PS4A/S is nearly as good just a bit smoother and quieter and the Procontact is only good for basic highway driving or grocery getting.

Yokohama Advan A052 255/40 R20 Hyundai Ioniq 5 N 3,000 miles March 11, 2026
I use these as essentially a rally tarmac tyres for street use. Trundling around traffic they are extremely well behaved for a semi-slick, hardly any tread noise even half worn and surprisingly comfortable, not worse than an UUHP sports tyre.

When there is no traffic and free view, I love them for their amazing grip and even more amazing feedback on the limit which is just a delight. Beats the OE P Zero, V107 and AD09 I've had on the car with no comparison. Just so progressive dry or wet. And effectively quiet, no 'someone is having an accident' tyre squeal firmly on the limit.

That grip comes in immediately and, against prejudice, is also there in the wet and when cold with just a few turns even near freezing.
When not used on track, heat related excessive wear hasn't been an issue, although I haven't yet used them above 20°C, will go to 285 width for that.

Downsides:
- The tread pattern and depth isn't made to counteract aquaplaning, these are not tires for the unaware, only for seasoned experienced drivers that know what they have under the car intimately. Once aquaplaning comes in the breakaway from high grip levels isn't forgiving.
- While wear isn't catastrophic even on my heavy car when not tracking, they will barely last 10"000km driven enthusiastically and only because I rotate them and run appropriate extra neg camber. Hoping 285 width will last a tad longer next. This is essentially a competition tire that only last one street summer season for me tops, if not from wear, probably from heat cycles. As such a very expensive tyre, but for a driver enthusiast, tyres are just as important as the car itself....

Where this data comes from

Owner ratings are submitted through the review form on this site, naming the tyre, the size and the distance covered, and are checked by hand before publication. Test results come from independent published tyre tests indexed by size, and label values from the EU EPREL database.

About the TR Score

The Tyre Reviews Score rates each tyre out of 10 using independent test results and the full body of owner reviews, so you can check a car-specific ranking against the wider evidence.

Who does the testing

Every test published as a Tyre Reviews test is run by Jonathan Benson, who has been testing tyres independently since 2007.
