“I just ordered Michelin Defender 2 for our 15 Outback . We've had 2 sets of Yokohama YK-CTX after OEM which only lasted about 20k (first set) and 25k (second set). I've had Michelin Defender (orig) and Michelin Defender2 on our Ford Taurus. Very comfortable and great tread life.”

What real owners are saying

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

Tire A

Goodyear Assurance ComfortDrive

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

Tire B

Michelin Defender2

Positive

Community sentiment toward the Michelin Defender2 is strongly positive, with owners widely praising its exceptional tread life, durability, and 80k-mile warranty. Many drivers and EV owners report excellent longevity and efficiency, though some note elevated road noise compared to premium touring tires or question its necessity for low-mileage driving.

“I have put Michelin Defender2 on my Model Y P right when I got it. I have driven 62k miles on them and they have plenty life left. Very impressed with their longevity. I didn't drive the Pilot Sport enough to really be able to compare, but the Defender2 is definitely not a performance tire. Efficiency is pretty amazing. I just drove from Dallas to Orlando and my average was 268 Wh/m going at the speed limit of 65 to 75. Road noise could be better, but part of it is that the Y is so well sound insulated from other noises that tire noise is the loudest thing left. It is far less noisy overall than my Model S was. So it might appear noisier only because the other noises are so reduced.”

“I have them on my 2024 'conventional' Mustang, and really like them.”

“I have Mercedes GLE 350 2018 with Scorpion Verde 255/50/19 R 107H. Drove 45 K miles in 4 years on it and still have 35% left. Got it slightly damaged on the side but still driveable so i am thinking about changing tires. For the same size, what would be better Michelin Defender2 or Primacy Tour A/S? Prefer quiet/smooth ride/noise isolation/safety.Never accelerate too fast/slalom or overusing breaks. Driving in Los Angeles. Max 80 mph/no quick turns. Thought that Primacy Tour A/S should be better for my needs as above, but read bad reviews (very low usable tire mileage ~ 35000 miles, wobbly, bad when raining) vs great for Defender2”

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.
