“A lot of our cars come with that Bridgestone. Often need replacement at only 30k km. They are also very sensitive to alignment, even slight off and the tires will wear unevenly and get noisy. Still better than the Dunlops though.”

No owner ratings of noise for Primacy 4. The owner half is the owners’ average (66): owners’ noise ratings barely follow the road tests, so the tests say nothing about how owners would rate it.

Higher is better. The Relative Score follows your weights below; category scores do not change.
Wet grip starts at “Important”. Treadwear starts at “Neutral” here: road tests measured it for at most one of the two tires, so it rests on owner reviews. Move the sliders and the scores update instantly.
Only one of the two tires has a score here, so this weight changes nothing in the head-to-head.

Community opinions on the Bridgestone Alenza 001 are split, largely depending on whether they are the run-flat variants. Many drivers praise their dry and wet handling, corner stability, and initial ride quality, while others criticize them for a harsh ride, noise, buzzy feedback on rough asphalt, and relatively fast treadwear. As original equipment (OE) tires on performance SUVs and crossovers, they are generally seen as capable in warm weather but poorly suited for cold temperatures, snow, or long-term tread life.
“have the alenza 001 on my cx5 for the past 3.5 years/40.000km,been rotating every 5k km and keeping the tire pressure correct,the wear is excellent,can go another 30k kms easy and israel has tough weather. perfect straight line and corner stability,wet and dry traction is top notch as well.been driving in hell hot and pouring rain weather.drive the car fast.had all sorts of brands and tires from all season to semi slicks,from primacy to r888 in my previous cars so i know a good tire when i have one only down side is its a harsh tire after 3years but its normal with bridgestone.i strongly recommend as a sporty luxury tire.”
“^^^^The Alenza 001 RFT is a summer tire not meant for snow or cold temps, and is a run-flat tire. As you surmised, it is a truck/SUV sport tire. If the sizing is correct, it should work out fine in your LC. However, as previously stated, RFTs are not as quiet as regular tires. The tire installer probably replaced them with RFTs because that's what you had mounted previously. If that's the case, you have experience with RFTs. Lexus used RFTs on the LC up until 2023 and switched to regular Hi-Po tires in 2024. Lou”
“Soon will have to replace tires on my NX350h Hi all, Soon I will have to replace the 2022 NX tires. The car came with "Bridgestone Alenza 001" so far so good, the ride quality has been nice, the noise is OK, and the rim protection (tire being wider than rim) worked well (narrow entrances with curbs in parkings in the city we live). We've made 75.000Km with the OEM tires and we will still make the summer with them before replacing them. In the area were we live is very rare to see snow. The car has no place for spare tire so runflats will have to be. I know runflats don't get "lots of love", but safety is a must and we will mount runflats again. The guy at the dealer offered us the GOODYEAR EFFICIENT GRIP 2 SUV. But as far as I've seen, those are not runflat. If we would like to improve, what would you recommend and why? Thanks!”

The Michelin Primacy 4 is generally praised for its comfortable ride, low road noise, and strong braking and safety in both dry and wet conditions. While many users report excellent tread longevity across tens of thousands of kilometers, some note faster wear on heavier electric vehicles or rough surfaces. It is viewed as a premium touring tire that is unsuitable for winter conditions, prompting some drivers to weigh its high price against newer models like the Primacy 5 or cheaper alternatives.
“When I bought my freshly imported 2014 Nissan Leaf in Sept 2020 it had 27,xxx km on the odometer and a full set of Michelin Primacy 4 that were sidewall dated from very late 2018, so likely only very low mileage on them. I put another 47,000km on them before replacing with a full set of Toyo Proxes C100 Plus in April 2024 which have also been great. The Michelin fronts were certainly very worn particularly the shoulders. I really rate Toyos so would encourage you to have a look. I’ve since put 21,000km on the Toyos and even after 12,500km, in May 2025 at their most recent WOF, the fronts still measured at 7mm and rears 8mm. P.S I paid $900 total for the 4 x Toyos inc. fitting, disposal etc.”
“Michelin Primacy 4 or Conti UC6 - Virtus GT Hey, i recently got a Virtus GT with stock Apollo alnac 4g tyres - looking to upgrade them. As per ChatGPT my options are Michelin Primacy 4 and Continental UC6 - budget is not really a problem. Overall i want good grip, handling, comfort and low cabin noise. Not going for Pilot Sport 4, because don't want to compromise on comfort for performance when i am not going to push my car too much, hence PS4 is a no no. But read it somewhere that with Primacy 4, there is a noticeable difference in mileage not sure if it means going up or down. Need recommendations on what i should get! Thanks in advance”
“I have Primacy 4s on my Volvo wagon. I've been very pleased. Plenty of grip, low road noise and longevity.”

Every category score blends two independent signals. 60% comes from professional tire tests (braking distances, lap times, noise measurements), each result compared with every other tire in the same test and newer tests counting more. 40% comes from owner reviews found online, adjusted for how generously each site rates. Both use one scale: the average tested tire gets 70, the best 100. When a tire has only one of the two, the missing half is estimated from the other and the score stays closer to average; with no road test and fewer than five owner reviews it gets no score yet.
Handling is the exception: road tests measure it inside the dry and wet scores, so its own row comes from owner ratings only and starts as less important.
