“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.”

Pros, cons & observations

Themes extracted from owner reviews found online — not the opinion of TireWheelGuide.

Tire A Alenza 001

Pros

  • Reliable dry and wet grip with confident handling
  • Stable and precise high-speed motorway performance
  • Good overall tread life and mileage for many drivers

Cons

  • Noticeable and occasionally loud road noise, especially as the tire wears
  • Firm and harsh ride quality, notably worsened in run-flat (RFT) versions
  • Rapid or uneven tread wear reported by some aggressive drivers or specific vehicle setups
All owner themes in the Alenza 001 review

Tire B Primacy 4+

Pros

  • Strong wet and dry grip and braking confidence, often cited as a big improvement over Bridgestone, Dunlop and Nexen tyres, including on powerful cars and PHEVs that previously spun their tyres
  • Comfortable, compliant ride with soft sidewalls that suits softly sprung and family cars
  • Low and even tread wear, with several owners reporting little visible wear after 5,000–10,000 miles and one reporting about 60,000 km in hot climates

Cons

  • Road noise and drone, especially on rough asphalt, was described as severe by several owners (Skoda Yeti, Lexus), contradicting other reports of quiet running
  • Reduced grip and confidence in cold, damp conditions, with two UK owners saying the tyre behaves like a budget tyre
  • Premium pricing, with some owners questioning value when life fell short of expectations

Tire A

Bridgestone Alenza 001

Mixed

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!”

How do we compare tires?

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.
