I was researching tires as a replacement for the noisy and rough-riding ultra-high performance tires on my 2008 Infiniti G35X. I wanted a tire that would preserve the crisp handling the performance tire had along with a smoother quieter ride. In other words, I wanted it all! Well, the Primacy MXM4 comes satisfyingly close! The handling is only a titch less crisp and the ride is much much smoother and quieter! Winter traction has been unbelievably great! But, after 3 years of wear on the Primacy's I'm faced with tires that will be fine for another 2 summers, but not one more winter. I will definitely buy the Primacy MXM4s again and next summer switch back the current ones to finish wearing them out.

The Primacy MXM4 tires came with our Tesla Model 3 LR dual motors. After only 13k miles, tread level is 1 and 2 for the rear tires. My wife drives this car and doesn’t even drive it hard. How can a tire rated for 45k miles wear out so fast? Will Michelin honor the warranty on these OEM tires?

My Michelin All Season tires are great because I occasionally drive up north in San Francisco during the winter and there is usually rain. The tires are unbelievably efficient and reliable. I have bought similar tires in past and have never had any problems.

These tires are great. Excellent wear, good economy and great handling, and pretty quiet on top of it all. Perfect for 3 seasons, as any "all season" would be. I run these on my Chevy Impala LTZ and Toyota Celica GT. I live where there is a real winter (Wisconsin) so I run real snow tires in the winter for proper performance and safety in poor road conditions.

Put a set of these wonderful tires on my Lexus ES to replace the OEM's. These tires gave my car the quiet comfort that I wanted and suprisingly added a level of handling and driving confidence that exceeded my expectations. Wet traction is also superior! There are many brands to choose from but Michelin's will always be my first choice!

These were OEM on Lexus ct 200h and I was very impressed when they were new. They were quiet and handled very well from the beginning (I am pretty hard of hearing, 'quiet' is a relative term) but most impressive is their handling when worn. I live in Washington State so drive in wet conditions regularly and these handled rain and standing water, at all speeds, extremely well when up to 95% worn. I have 58k miles on them now and trying to get 1-2k more. Not sure how to judge their assistance with fuel efficiency but will say that over the life of the tires I avg. 45-46mpg. Will definitely replace with the same.

The Michelin Primacy MXM4 have been the best tires all around I have owned. I drive 40,000 miles a year in all weather conditions from mountain snow and ice to heavy Oregon coastal storms. I have mismatched front and rear tires on my Mercedes CLK and the rear tires currently have 42,000 miles on them but are getting close to replacement in the next 3-5,000 miles. The front tires have more than 50% tread left at 56,000 miles. The last set of MXM4 tires on the front were changed out at 80,000 miles. The MXM4 tires stick to the road like glue on hard cornering. These are impressive tires!

This is the second set of this particular tires that I have owned. The first set were on my first, brand new 2007 Acura TSX and the performance these tires showed just couldn't be compared to any other brands. I refused to put any other tire on that car other than these. I just last month purchased a 2016 Acura RDX and it already came stock with this brand and model of tire on it and I was sooooo happy about that because I knew I had a good set of tires on this vehicle. My wife went on a road trip and she was happy about how quiet and smooth the ride was. Then I went on a road trip and I certainly didn't have to guess how well that went!!!

Did a lot of research on forums and articles and decided on the Primacy's for my Grand Marquis and I just love them, yeah they were pricey but you get what you pay for and they're worth every penny spent. Highly recommended from a retired mechanic who knows quaality.

I have only had these tires on a new car, a Hyundai Genesis, since Mar,2016. Their handling and stopping performance has been outstanding. Their road noise level is really annoying, which is probably a result of the performance design. The ride comfort is extremely poor, with every bump in the road transmitted to the passengers. The tire are Primacy X4M4 245x45x18 96V, which accounts for the noise and ride issues we have. The trend by auto makers to ever larger wheels and low profiles for looks is the real problem. They should provide for different wheel sizes other than the set size for a trim package. You can go up but not down.
