“I have the Maxx TT on my car for about 1000 Km which included two slalom sessions. I am very pleased with the ride quality and dry traction. It is much quieter than the OEM tires. I have not had a chance to drive in wet road yet.”

Higher is better. The Relative Score follows your weights below; category scores do not change.
Wet grip starts at “Important”. Treadwear starts at “Neutral” here: road tests measured it for at most one of the two tires, so it rests on owner reviews. Move the sliders and the scores update instantly.
Only one of the two tires has a score here, so this weight changes nothing in the head-to-head.

From Reddit, forums and review threads. Not part of our score
Community members generally praise the Dunlop SP Sport Maxx TT for its quiet road manners, respectable dry and wet grip, and solid track and cold-weather road performance compared to stock competition-oriented tires. Some drivers note relatively soft sidewalls during aggressive slalom events on heavier vehicles or limited grip before coming up to temperature. Overall, drivers find it to be a capable, comfortable summer tire that balances performance and daily drivability.
“We have these tires on my 18 Grand Sport and my wife’s 17 Z51 Convertible driving in Ohio. Very pleased with these tires! Probably should be OEM for these cars. Handle very well. Doesn’t throw gravel up on the cars like stock tires. Cold weather grip is very good! Stock MPSS are scary below 50 degrees. We have had good success with Discount Tire for purchase and install.”
“In Hong Kong, if your style is aggresive, sport maxx is not enough, i am using AD08 and RE11 is not bad”
“After 3 sessions of autoslalom, I can say that the sidewall is too soft for this heavy car. I have the front tires set at 39 psi cool. I may try higher pressure next time to see if it can reduce the tire roll and maintain traction. In term of day to day driving, this is a great quiet summer tire. It performs well in wet too.”

Community sentiment towards the Michelin Primacy 4 is generally positive, with drivers frequently praising its quiet ride, comfort, and dependable wet and dry braking performance. Several owners note impressive longevity reaching over 50,000 to 70,000 km, though some EV and SUV drivers report accelerated wear and fragile sidewalls over rough terrain. It is commonly viewed as a premium touring tire that commands high prices compared to competitors.
“I have used Michelin tires before but recently I already have used Nankang tires. I compared Michelin and Nankang tires after testing. It was quite a pleasant surprise that the Nankang AS1 was nearly on par with the Michelin Primacy 4 in braking distance. Both tires performed exceptionally well, with the Primacy 4 only stopping slightly 3 meters shorter than the AS1.”
“Rapid wear on Michelin Primacy 4, 2017 Forester 2017 Forester in Mexico City, where there are lots of potholes and speed bumps and a LOT of rain. I got a set of Michelin Primacy 4+ tires at Costco three years ago and they've got about 30,000 kms -- 16,000 miles on them. Tread is down to about 3.5/32nds (in the middle, slightly less at the sides). The original Geolandars lasted very far beyond that in the same conditions. I'm getting a bit antsy at the tread depth. Wonder if anybody else has seen such rapid wear.”

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.
