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.

Top 3 Yokohama AVS dB v550 Reviews

Given 96% while driving a Honda Civic (190/60 R15) on a combination of roads for 56,000 easy going miles
I have a 2004 Honda Civic 170i sedan. I previously had this set on my Company BMW (225/45/17) Got about 70000kms with the BMW. On the Honda - Close to 90000kms!!
Excellent tire. Very good all rounder. Great value for money- Yes they can be pricey, depends where you buy it, But the long life span is definitely worth every penny.

Excellent in wet and dry. Low, if not no noise. Much better than the Goodyear Efficient grip that came with the car.

Given 99% while driving a Honda Fit (Jazz) (225/45 R17) on mostly country roads for 5,000 average miles
These tires transformed the Honda Jazz/Fit. THe ride is so much softer and much more quiet than the OEM tires.

Given 76% while driving a Jaguar XJ6 (225/60 R16 W) on a combination of roads for 25,000 average miles
These are excellent tires for a heavy luxury car like the Jaguar. Biased towards silence and comfort, they suit the relaxed nature of the car very well. They are not the grippiest in the wet, but they give up progressively and if the tail slides it's easily caught. I will buy them again as they suit tha car so well, and they really are very quiet running.

Latest Yokohama AVS dB v550 Reviews

Given 87% while driving a Lexus LS400 (225/60 R16 W) on mostly motorways for 0 average miles
The best tires I have had on my Lexus LS400, having used many different brands on this car over the years. The dB550s are very quiet and smooth, yet offer surprisingly good handling and grip. The big problem is availability; I could not purchase another set, as Yokohama Japan is no longer shipping the size I need to UK. Assymetric tires are noticeably noisy on the LS400; the OE Dunlop D8z were symmetrical and quiet. Being a directional V-shaped pattern, the dB550s do tramline more than desirable, but nowhere as badly as the otherwise good Uniroyal Rain Experts my car wears currently.

Given 50% while driving a Audi A4 (215/55 R16 V) on mostly motorways for 10,000 average miles
Fitted to an Audi A4 1.9TDI (2004). In 16000km they've worn down to approx 50%. Pretty quiet, as advertised. Better than average feedback and straight line response. Good, wide water evacuation channels, but too soft for the rough aggregate of South African roads.

Given 80% while driving a Volkswagen Passat 1.9Tdi (205/60 R15 V) on a combination of roads for 10 spirited miles
Very impressed with the 'chuckability' of the car on country roads, easy to 'read' in the wet - can hold it right on the limit - need a lower profile to fully explore dry road limits (I never got there - you would really need a circuit to fully explore).
Very confidence inspiring on motorways (usually 80 to 90, wet or dry!), the only thing to watch for being flooded areas, otherwise driving in wet same performance characteristics as dry, not quite! :-)
Watch for the diesel spills/ change in road surface, readable when you find them but since you are probably closer to the limit on these tires (confidence) you may not have much room to spare!
Big disapointment is wear rate, fronts have little left after 10,000 miles - rears about 30% worn - would fit again if I can find them!
