“I'm not particularly worried about stuff like that, more wondering if I could eke any more grip out when accelerating hard in less than ideal conditions. The current PS4s give me no trouble braking, turning and driving through standing water, but they do struggle to put the power down at the minute.”

What real owners are saying

From Reddit, forums and review threads. Not part of our score

Tire A

Dunlop Grandtrek AT20

We haven't collected enough community discussion about this tire yet.

Tire B

Michelin Pilot Sport 4 SUV

Positive

Community sentiment toward the Michelin Pilot Sport 4 SUV is generally very positive, with owners highlighting its strong grip, handling precision, and suitability for heavy performance SUVs. Users frequently compare it favorably to older Latitude Sport 3 and standard passenger tires, though they emphasize its summer-only limitation below 40°F and note trade-offs in price and tread life.

“I'm leaning towards the Pilot Sport 4 SUV over the LS3. I'd really like to see how much better these tires grip. Although it sounds like I'll be sacrificing a little comfort, but with air suspension I'm not too worried.”

“Nope nope nope. I live in the SE and my RWD sports car get squirrelly with normal driving when it drops below 40 on my PS4Ss. You’d be in a ditch first bit of snow.”
rennlist.com

“Have a 2014 CTTS with 21" wheels. Just had Michelin PilotSport4 SUV All-season put on. Before that had Michelin PilotSport4S. Have about 1K miles on the new tires, and no experience with it in winter weather yet, but prefer the ride quality over the PS4S. The PS4SUV are a softer ride, yet still have plenty of grip when I hit the "Sport" button. IMO, the PS4S is overkill for the Cayenne. Obviously, subjective and YMMV. Does your wife engage in "spirited" driving? As background, I have PS4S tires on my 2016 Spyder and love them.”

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.

Community buzz from Reddit and forums is shown for context only — it never changes the score.
