The Tire Reviews Score is the most comprehensive tire 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 tire 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.

Given 90% while driving a Suzuki (175/65 R15) on a combination of roads for 60 average miles
Original fit to 2011 suzuki swift. Just changed out at 98,000km of mixed country and urban driving. Great grip, very low noise and fantastic wear rate. Car is light an modestly powered and driven modestly. Superb experience. Have replaced with identical tire.

Given 33% while driving a Honda Accord Tourer Type S (225/45 R17) on mostly motorways for 30,000 average miles
I bought tires twice new set and always same - big noise and after 10000 miles tires were close to dead, luckly same bad behavior next 20k miles but honestly last 10k was really too danger to drive. Never more Yokohama. waiting money and rather pay a little bit more to get more reliable.
I bought Goodyear EAGLE F1 ASYMMETRIC - 225/45 R17 91 W and totally different level of tires

Latest Yokohama dB super E spec Reviews

Given 70% while driving a Honda Civic FD1 1.8 i Vtec (205/60 R15) on a combination of roads for 6,000 average miles
I had these tires installed in my Honda Civic 8th Gen to replace the worn out stock fitted Bridge Stones.

The highlight of the Yoko's is the comfort. They are extremely silent and soft on the car's suspension. In the first few weeks after getting these installed i actually looked forward to driving my car at work and around town everyday as the car felt quite and smoother than before. The tires absorbed the bumps on the road beautifully.

The wet grip of Yoko's is normal, In my opinion the bridge stones when new offered a much better grip in wet conditions. The confidence level remains a little low when negotiating round abouts and narrow exits from the flyovers and motorways .I felt the car slipping away a little at speed of 50-60KM when negotiating narrow turns.

The dry grip however was satisfactory.

Given 57% while driving a Toyota Yaris (185/60 R15 H) on mostly town for 14,000 easy going miles
OEM fitment on a 2007 Yaris; Quiet running tires and good dry grip. Average in the wet, but hopeless in slushy, snowy winter weather. Nowhere near the confidence levels/capability given by the Bridgestone Touranzas on our other Toyota.
But worst of all is the very high wear rate for tires that are driven gently around urban area with very little motorway use. Down to wear bars on the fronts at only 13,500 miles.

Given 87% while driving a Toyota Wish (205/55 R16 V) on a combination of roads for 30,000 average miles
Have been using the tire for my past 3 cars i've own.

Compared to major brands slient/comfort for this tires are thumbs UP

Taxi company in singapore should invest on this for their customer comfort. An incident when i was in singapore that their mercedes cabs are using low budget tires, causing the tire hollow sound when travelling at 80km/h and above which i think it should be changed for customer comfort.

Such a comfortable car on budget tires like *Taxi Radial, Hankook OPTIMO K715, Pirelli P3000 and Goodyear EfficientGrip.

Great tire for daily driving currently on 50,000km yet the threading are still good for another 10,000km.
