“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 opinion on the Goodyear EfficientGrip family is mixed, with users frequently praising its high tread life, comfort, and solid wet braking compared to rivals. However, several drivers express concerns regarding soft sidewalls prone to pothole damage, vague handling dynamics during spirited driving, and disappointing cold or wet traction when used out of season. Many discussions also center on comparing it against alternative touring tires like Michelin Primacy and Continental PremiumContact.
“Hi Llew! Currently running Pirelli Cinturato P7 Run Flats. I don't do a lot of long-distance driving anymore, so I am fine with not having a sporty feel, but I wouldn't mind trying that out, being new to BMWs. So the Khumos apparently are a better fit for that. I ran the three 3 choices (Khumo, GY, Pirelli) through chat for a comparison, and it spat out that the Goodyear EfficientGrip is a very "compelling" tyre and the better choice. Not sure what to make of that.”
“Goodyear Efficientgrip Performance SUV are summer tires, not all season tires, I believe.”
“Hankook ventus prime 4 VS Goodyear efficientgrip performance 2 I cannot decide between these two tires for ages now. Customer reviews seem all over the place. I drive a tuned volkswagen polo mk6 2020. I need something that inspires confidence for spirited driving in corners with good stability, mainly dry handling and braking but also relatively comfortable. So far I've learned that the goodyear is more comfortable, better in the wet, better at braking but extremely lousy in handling because of the soft sidewalls. Can someone that has used the EGP2 confirm those claims or are they exaggerating. Base spec polos are known for a harsh ride and I live in the balkans. The roads are full of potholes and sometimes you can't even drive around them. specs: 195/55R16 87V”

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.
