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'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.

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.

I have been putting Michelin Defenders on all my vehicles over 15 years & I usually get 80 to 90k on my tires but not this time. I bought 2025 Navigator & it came with Michelin Primacy & I was really exited abt these tires. Something new & will probably last long. In 9k Miles tires ripped on side, nail 2x & already had to replace one tires. These tires are too soft & definitely not good for NYC roads. I think Michelin needs to do better.

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.

From an engineering perspective, it would appear that the tire design was not considered when running on sanjas, (drainage cuts). The tread pattern runs parallel to these cuts and as it skips, from cut to solid, the friction fluctuates causing significant vibration in the perpendicular direction. This effect is further magnified when on ice and wet sanja roadways. It feels like the vehicle is hydroplaning. On non-sanja roadways, the tires perform as expected.

Obtained these tires from the local Ford/Chrysler/jeep dealership. Severe balancing problems. Hard shaking from two of the tires at 65 mph or higher. Had two alignments and tires rebalanced twice. No improvement. Stay away from these tires! Dealership insists they are recommended as a Michelin replacement to original tires that came with the vehicle (Premier LTX, which are no longer made apparently), but these Primacy LTX are a very inconsistent tire.

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.

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.

The Michelin primacy ltx came on our Jeep Grand Cherokee Limited L. Now with less than 13000 miles on the Jeep all 4 tires are being replaced by me. One at a time went flat with a split in the sidewall next to the tread. I thought someone stuck a knife in the first one so I replaced it. Since supposedly vandalism was the cause I had to pay. Now 2 weeks later the forth tire just went flat with the same kind of hole. Now I see where others are having the same problem. Don’t buy these . Just don’t.
