Michelin recently added another player to the Grand Touring All-Season market with its new Primacy MXM4, and we just finished putting it through the ringer here at Tire Rack. Not to be confused with other models like the Pilot HX MXM4 or the Primacy MXV4, this new model could be poised to take over the category.
On our Real World Road Ride, I was extremely impressed with the tire's ability to mask small imperfections in the road. There's one spot, a small patch, that I look for every time, and the Primacy MXM4 rolled over with minimal noise. It smoothed out the rough expansion joints better than its competition as well. Overall, these tires were a real pleasure to drive on.
On the track, it's difficult to expect a touring tire to be a top performer and produce really low track times. But my experience was a good one with the Primacy MXM4. I thought the cornering through the slalom was stable and the braking ability was above average for this category.
Stay tuned for the full results.
