I bought these tires on Saturday November 20th and left the next day on a 2200 mile round trip. I was very impressed with the quietness of the tire. The handling was great. However, the mileage on my 2010 Prius decreased by 5 miles per gallon. This is very disappointing. If MPG is not important then I recommend this tire. For the Toyata Prius it is not a good choice.

Review of Primacy MXM4 after 6 years and 84,000 miles. Best tires I've ever owned. Tires are on a 2003 Infiniti I35. Excellent in all areas: wet, dry, highway, around town, even treadwear on all four, and always quiet. Now worn to 3/32". If you have a newer sedan, and can still find the size you need, buy them.

I bought the tires in 2010 (it is now 2013) and they have been great. My car used to handle horrible in the snow and also the ride used to be quite rough. Since the new MXM4 tires the car feels much better, handles excellent in dry, wet or snowy roads. No complaints at all, highly recommended!

Replaced original MXV4 with a set of MXM4 after nine years just due to age. Don't drive many miles but drive hard and fast. These are better than the MXV4 for my liking. Great in wet or dry handling and breaking and they just do not lose air. They have transformed my 2002 VW Passat Wagon with 4 Motion to better than new, quiet, handling and ride comfort.

These tires came standard on my Tesla 3 performance. Present Km reading is 69,000 and I use winter tires for about 5 months/year. These tires have done approx 40,300Km and my Tesla dealer advises replacement. This means these tires are well short of the 90,000Km claimed life!

I purchased a 14 Avalon xle touring with these tires on it from factory. I've had the car for a little less than a month and these tires give the car a very comfortable ride! I can't speak on the tread life for only having it for such a short time now but I use to have the Pilot MXM4 on my 11 Accord ex v6 and the tread lasted very well for daily spirited commutes to work. I recommend the Primacy and the Pilot MXM4 for anyone looking for a quiet comfortable ride without sacrificing handling, traction and performance.

I drive primarily highway. I've been making the 86 mile round trip commute for nearly 14 years. I'm over 250,000 miles in that period on a variety of tires (mostly Michelins). I thought these tires were great in terms of comfort and handling from Spring through Fall. Unfortunately, I only got 43,000 miles on these tires instead of the 55,000 miles for which they are rated (the first time I've failed to go over the treadwear rating). I also found the winter traction to be below-average for the category. It is apparent to me that this tire is highly biased toward touring performance in the dry/wet at the expense of winter.

The Primacy MXM4's were OEM on my brothers 2016 Cadillac ATS. After riding in his car I immediately noticed a huge difference between the Pilot MXM4's that were OEM on his 2014 ATS and OEM on my VW Jetta Wolfsburg Edition. The Pilots felt rock hard and were quite noisy! I put the Primacy's on my VW and their incredibly quiet, cozy and responsive!!!

I have been driving on these tires for a little over 9 months now and they still look new. They are on a 2006 Cadillac DTS Sport and replace the OEM tires. The improvement in handling, ride comfort, and quietness was dramatic. These are easily the best tires I have had on any vehicle I have owned in over 30 years of driving. The low profile makes the car look sharp and the ride is smooth and quiet with very good responsiveness to acceleration and lane changes. This Caddy can push the tires when running in sport mode -- the active electromagnetic suspension coupled with these tires makes for confidence when a little aggressiveness is called for. I spent a lot of time deliberating about what was "good enough" and realized that for just a little more I could have the best. I have no regrets and these will be my only choice for the long run.

These tires came standard on my 2011 BMW X3. I'm old school and was very concerned about RFT usage. It unnerved me to not have a spare on-board. I have about 7,000 miles on the vehicle and am pleasantly surprised all around. The car handles like a big cat, no surprises, no squeals, just a on-rails feeling in sweepers, on the Interstate, in rain, in hot and cold. Last winter was a non-winter here, so I have no experience with these puppies in slush, snow or on ice. But so far, so good. I've been to the Smoky Mountains and back, on dirt, gravel and paved roads. No issues, knock wood. Now if BMW would only install a dipstick to pacify this Boomer, I'd be even happier. Electronic oil level indicators? Bah, humbug!
