Best test result: #1 of 15 in 2021 Auto Bild 19 inch Summer Tyre Test (dry braking)
“A note about the pilot sport 4 S: in cold weather (below 5 degrees) even if it isn't icy, the tyre compound hardens and has dramatically reduced grip. They are excellent summer tyres though, good in the wet too. These days I run Uniroyal rainsport 5 and they're very good.”

- Developing loud road noise, hums, or low-frequency harmonics over time as they wear

Tire B

Michelin Pilot Sport 4 S
The community widely regards the Michelin Pilot Sport 4 S as a benchmark max-performance summer tire, praising its outstanding dry and wet grip, stability, and daily driving refinement. Common criticisms focus on its premium price, rapid tread wear on high-powered heavy vehicles or hot track sessions, and significantly reduced grip in cold weather. Many enthusiasts consider it an ideal street tire, though some note softer sidewalls compared to predecessors or recommend dedicated track tires for hard circuit driving.

“I had a similar experience with Discount Tire and brand new Michelin PS4S's. I clipped a large lane marker (not a dot, a turtle) with both driver's side tires and pinch-flatted them both. I had driven them less than 10 miles so Discount Tire replaced them for only $50 without me even asking for a discount. I had purchased them for about $450 each and didn't buy a road hazard warranty, so I was very pleased with Discount Tire.”

“My 2023 20th AE Golf R came with Hankook tires , and I've been very pleased with them. I'm a fairly aggressive driver and frequent the twisty roads in the Santa Monica Mountains. I also have a mildly modded Mk VI Golf R shod with Michelin Pilot Sport 4s tires on factory 18" rims, and the Hankooks seem to perform almost as well in the dry, but outshine the PS4s in the wet. I will most likely need new tires next year, but I am undecided between the Hankooks and the Michelin PS4AS tires . As for Continental tires ... I use Continental tubular tires on my road bicycle, but have experienced many problems, including massive chunking with them on my 1974 BMW 2002Tii and my 1979 Scirocco Gti , so I am not going to use them on my cars again.”

“My 2020 Kia Forte GT came with Michelin Pilot Sport 4 S tires. Those were not going to work in the PNW as a daily driver tire. I went right to Costco and bought some Michelin Pilot All season tires, the ones that compete with the Continental DWS at the time. I listed the take offs on Craigslist for $400 and sold them that day.”

How do we compare tires?
Every category score blends two independent signals. 60% comes from professional tire tests (braking distances, lap times, noise measurements), each result compared with every other tire in the same test and newer tests counting more. 40% comes from owner reviews found online, adjusted for how generously each site rates. Both use one scale: the average tested tire gets 70, the best 100. When a tire has only one of the two, the missing half is estimated from the other and the score stays closer to average; with no road test and fewer than five owner reviews it gets no score yet.
Handling is the exception: road tests measure it inside the dry and wet scores, so its own row comes from owner ratings only and starts as less important.
