Primacy 265/65-18's came on a new Chevrolet Silverado 4x4 . All was good until first time on grooved pavement when it started rocking side to side with less than 500 miles on the vehicle I thought something was wrong with the truck this was not the case! As soon as vehicle left the grooved pavement handling returned to normal.

I bought my 2020 Chevy crew cab new in Oct 2019 and the OEM tires were the Primacy LTX. I have lived in Houston, Philadelphia, and now North Carolina. I have 55k miles on these tires and no complaints. I have moved myself several times and I do a lot of DYI which both have required a lot of towing of large trailers. With 45k miles on these tires they still saved our life one day and met the ultimate challenge. While cruising the interstate down a large grade towing a fully loaded 12’ trailer an18 wheeler suddenly cut us off in the passing lane and hit the breaks. I moved to the right lane sped up to avoid traffic behind me now near the bottom of the grade a when another 18 wheeler began to pull slowly off the shoulder into our lane. I stood on the breaks because trucks were on my left and vehicles behind me moved to the shoulder cutting off all options to avoid a violent and possibly fatal collision. The tires performed admirably and allowed me to control our skid and they bit the pavement hard enough to stop us short of that truck. I have nothing but praise for these tires and with winter coming soon I am looking for another set to replace them.

First off, this tire has a bad reputation. I think the reason people don’t like it, is they’re using it for the wrong purpose. The Primacy is not for off road use. It will perform well for long trips, but its life won’t last like the defenders. This is a fuel efficient tire-low rolling resistance. It is best suited for stop/start city driving, and/or highway driving if you are going to drive less than 55,000 miles in 5-7 years. 7 years is about as long as you want to keep any tire on the road; thanks to the sun and oxygen in the air.

2 of the 4 leak like a sieve at 12,000 miles. Came on new 2024 Nissan Frontier. Multiple tiny leaks in 2 of the tires without punctures. Can’t believe Michelin would put their name on them. Can believe Nissan would choose to put them on their vehicles. Only 42,000 miles short of guaranteed mileage. Worthless.

These tires came as standard on my 2022 Nissan Frontier, I got a puncture in one in less than 3000km's of driving. The tire was ruined. I was not offroading, i was driving on a regular gravel road. If you stick to paved surfaces exclusively they may be ok.

Bought a brand new 2023 Jeep Grand Cherokee L in September 2023. My wife put about 6k miles on the car, and this back right tire blew out while she was driving on the highway. Never any off-roading. No impact to cause the blowout. Clearly a defective sidewall. Very disappointed, and this defect could have killed my pregnant wife were it not for her quick reflexes to pull over immediately.

Our first significant snowfall in NW Pa this weekend and I have gotten stuck once while other 4wd's were able to go through the same snow, and lost control twice due to spin out and inability to brake. These tires came on my new Silverado EV and I am heading to the Chevrolet dealers tomorrow to lodge an official complaint with General Motors and to replace these tires. I have been driving for 50 years with nine different trucks in all kinds of weather in NW Pa and I have never had a worse tire on a truck than these for performance in the snow. I cannot believe GM would put them on a vehicle as standard equipment.

As is the case with any car I purchase if it is not equipped with Michelin tires I start shopping immediately as with the case with my 2018 Terrain. I have had Michelin tires installed on other vehicles and the ride,handling, and tire life can`t be matched. Will not purchase any other brand than Michelin. Have had "top brands" in the past and they in n way stand up to the Michelins. The Primacy LTX tires are more than living up to expectations.

These Primacy LTX tires came on our 2021 Kia Telluride that we bought new. I recently noticed a puncture in the sidewall on one tire. It almost looks like the rubber split. It looks pretty deep but the tire is still holding air. This is my wife's car and she drives on the interstate a lot; Needless to say I'm concerned that this tire could burst at any moment. My wife says she hasn't hit anything that could cause this damage. Also, there isn't any damage to the wheel. After reading a lot of other reviews I'm compelled to think that this is a faulty tire design or quality escape from Michelin. Since this is a safety issue I have to replace this tire and given that our Kia is AWD, it looks like I'll be replacing all 4 tires that don't even have 30k miles on them. I had previously held Michelin in high regard but have lost confidence in them after this.

I've had these tires on my 2020 Silverado right from the factory and put 78,000 miles and they still have more life left. I expect to get around 85,000 miles out of these before replacing with another set of Primacy LTX. These tires are quiet and have delivered fuel economy exceeding EPA estimates.
