The Tyre Reviews Score is the most comprehensive tyre scoring system available. It aggregates professional test data from multiple independent publications, user reviews, and consistency analysis using Bayesian statistical methods, weighted normalisation, and recency-adjusted scoring to produce a single, reliable performance rating.

Methodology & Configuration
Scoring Process
  1. Collect Test Data: Gather results from professional tyre tests across multiple publications. Minimum 1 test(s) required.
  2. Normalize Positions: Convert test positions to percentile scores using exponential weighting (factor: 1.2).
  3. Apply Recency Weighting: More recent tests are weighted higher with a decay rate of 0.95.
  4. Incorporate User Reviews: Factor in user review data (minimum 5 reviews). Weight: 15%.
  5. Bayesian Smoothing: Apply Bayesian prior (score: 7, weight: 1.5) to prevent extreme scores with limited data.
  6. Calculate Final Score: Combine all components using normalization factor of 1.1. Max score with limited data: 9.5.

Top 3 Bridgestone Alenza AS Ultra Reviews

Given 10% while driving a BMW X3 (225/45 R17) on a combination of roads for 18,000 easy going miles
Bridgestone Alenza tires are a very dangerous tire to put on a vehicle if you intend to drive in Alberta, Saskatchewan, Manitoba or Northern Ontario in winter/ice . There is absolutely no grip on ice or snow and are hazardous to your safety when attempting to turn and/or stop the vehicle. I DO NOT RECOMMEND this tire for use on any vehicle during a Canadian winter.

Given 26% while driving a Jeep Cherokee Limited 2015 (265/50 R20) on mostly motorways for 15,000 easy going miles
Worst tyres ever, they didn’t last for more than 25,000Km even with regular rotation and balance!!!

Toyota 2006 Avalon (245/55 R19) on mostly motorways for 6,000 easy going miles
I took off oem Bridgestone. ecopia. On my 2017 Highlander. We we left Costco my wife said what's that noise. Tire road noise was far greater than old tires with 50k on . Costco said they would put on a lesser tire. I made a mistake reading reviews .

Latest Bridgestone Alenza AS Ultra Reviews

Given 67% while driving a Ford Edge (265/45 R21) on a combination of roads for 1,000 average miles
I just put these on and about 1000 miles on them. So far, I like them. They are louder than my factory installed Continentals, but they are more aggressive. They run smooth and handle well. They grip decent. I ran them on dry, wet, snowy, slushy and ice. They did really well. I didn't even notice the consistency change much under me. I lost about 2mpg so far. No changes other than the tires. Talking to the tire folks, rotations every 5k and alignments are CRITICAL to getting the life out of them. Don't be mad when your car wears them out because of a lack of maintenance. They do great for my AWD daily driver.

Given 100% while driving a GMC Yukon Denali (285/45 R22) on a combination of roads for 0 average miles
I love my Bridgestone Alenza AS Plus tires - i have them on a 2015 GMC Denali Yukon - and i have 72,000 miles on them - i feel like they could easily go another 20K - they are wearing great - but now i am looking around to see if any tires are better than these for the money.

Given 85% while driving a Chevrolet silverado 1500 (285/45 R22) on mostly country roads for 1,000 spirited miles
I have only had these tires for about 1000 miles of winter driving. They are on a 2020 Chevy Silverado High Country 6.2L. I have been running the Alenza for close to 20 years on Chevy trucks, but this one came with something else which I was not happy with. When one got damaged, the dealer told me I could get the new Alenza AS Ultra. I thought about it for a minute and then scraped the old ones. I got a better ride and better performance on ice and snow. I called the dealer and thanked him for the recommendation...it was a one way trip for me! I'm hoping that the tread life is similar to my past experience, which as been 45K to 50K on the two 5.3L Avalanches.
