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 Primacy Tour AS 275/50 R20 Mercedes Benz GLE 450 27,000 miles July 21, 2025
Noisy. These came on my Mercedes GLE450 and have been noisy since they had a couple of thousand miles on them. They have a resonant hum that only goes away on the smoothest roads. Wear is average for a heavy SUV. The rear tires will need replacement around 30,000 miles. The front tires have significantly more tread left. (Rotation of the tires is complicated due to different wheel offsets between front and back). Handling is OK, but not great. Lots of understeer with these tires. Ride comfort is good (I have the air suspension). Considering the Pirelli Scorpion Zeros all season as replacements.

Durun A One 275/50 R20 Mercedes Benz ML350 23 miles October 8, 2024
These max figures may seem weird, but I genuinely find that these cheap tyres are excellent all-rounders. I have them mounted on my W166 ML350 Benz and while I don't drive it as if I stole it, the car does get some vigorous handling. Wet or dry road, there's no difference, they're quiet at any speed, they don't generate any anxiety on tight corners, although the car's electronics do take over if I approach the limit, and the wear factor is quite amazing. At 38,000km, there's still plenty of tread above the wear bars and I estimate that another 25k-30k is well within expectations. I'd definitely buy them again.

Michelin Pilot Sport 4 SUV 275/50 R20 Mercedes Benz GLS 500 bi turbo 30,000 miles April 9, 2024
Already my third set of tires. The first generation of 2021 had lousy mileage (had under 5mm left after 8000 km) but has improved since and I typically do 30'000km until 4.4mm of tread is left (I never go under) starting with 6.8-6.9mm for a new one. Second comment is that Michelin seems to offer less tread on their tires as compared to competition - all things equal this makes for lower mileage. Overall I never liked Michelin tires and would take off if provided with a new car however after I have them on my Noble M600 (custom made for Z rating and size) I tried them on powerful SUVs and are positively impressed to the extend I switched over from ContiSportContact 5 SUV (also a great tire reviewed separately) for most of my cars. A balanced tire equally good for dry and wet. Surprisingly very good for offroad ALTHOUGH not an offroad tire by nature/design. A summer performance tire (contrary to many of the ones I used) maintains positive characteristics when nearing to freezing temperatures and even on wet roads just above freezing. THIS IS not a tire meant to be driven anywhere close to this levels but reassuring if you get surprised late autumn. Very good aquaplanning resistance and likes dynamic driving (although I add typically between 0.2-0.4bar (depending on style) of pressure for everyday driving. Looks also very good although due to tread may be slightly overbearing on some cars (just thinking whether to mount them on my Volvo XC90 V8 as they may have just to heavy looks. On the Mercedes SUV which is an ugly block anyhow they look gorgeous. If you opt for comfort, low noise levels this is not a tire for you but these parameters are secondary or even tertiary as is price for me. Safety, balanced performance and dry/wet/aquaplaning/stability being key for me - this is where the tire excels. Michelin (as any other producer) will not acknowledge this and I did not do a scientific side-by-side test but tires vary moderately (to even more than moderately) depending on country of origin. Also when reordering do not trust only the name/model but if you want same performance going forward check the SAP (or equivalent) systems number (I have been advised so by two premium tire manufacturers and in true life the difference can be significant - both in terms of e.g. dry/wet optimization as well as OEM vs aftermarket). The ones reviewed come from Hungary.
