“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.”

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.

Themes extracted from owner reviews found online — not the opinion of TireWheelGuide.
From Reddit, forums and review threads. Not part of our score
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.
“If you don't drive your car hard and need a good all around all weather tire, it is a fine choice. The only reason it's predominantly labeled an SUV tire is because it comes OEM on a bunch of SUVs like the highlander, etc and likely has a weight rating to accommodate. It works for the LC because the LC weighs as much or more than most crossover/SUVs such as the grand highlander does. edit: if you got the Alenza 001 which is a runflat tire it's going to be loud, as all run flat tires are.”
“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.”
“If you're not satisfied with the ride, blame that on the Alenza 001 being a run-flat. Those Michelin Lattitude Sport 3 ZP tires are also run-flats. BMWoB ( BMW of Bubbaville) routinely lowers the tire pressures in their loaner cars with run-flat- tires , so people won't hate the ride and buy an Audi next time. I make a point of putting my loaner cars' tire pressures back where they're supposed to be... and that makes them ride like crap. Hopefully, you bought your X3 with the optional spare tires . That gives you the option of going with non-run-flats. The gold standard in non-run-flats in those sizes are the Michelin PS 4S (summer, max-performance) and PS A/S 4 (all-season, ultra-high-performance). Don't throw your OE Bridgestones away. There's a pretty good demand for them as used tires for lease-turn-in. BMW FS requires 4/32" of tread at lease turn-in or they can hit you with a $300/tire "excess tire wear fee."”

Bridgestone Alenza 001, 55 vs 52 on our treadwear score.
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.
