“The tires are over inflated for transport. The dealership should set them to the proper PSI during PDI but that's not always the case. I had 55 PSI in mine which explained the rough ride.”

Tire A

Michelin Defender LTX M/S2

Positive

The community widely views the Michelin Defender LTX M/S2 as an outstanding highway and daily driving tire, praising its smooth ride, low road noise, and reliable wet traction. While considered an ideal replacement for noisy all-terrain or OEM tires, some users question its performance in severe winter or deep mud conditions compared to dedicated off-road tires.

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.
