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.

Given 97% while driving a Suzuki Suzuki Ritz (185/70 R14) on a combination of roads for 0 easy going miles
I have been using this model tyre for around one year and driven almost 15k kms. I am very happy for choosing this tyre, the quality of the tyre is excellent.
It gives shear comfort and confidence while driving. The wear and tear is also too good. Even after 15k kms the tyre still looks brand new and progresses in the same way.

Given 57% while driving a Lexus IS250 RWD (225/45 R17) on a combination of roads for 500 easy going miles
Went from Jinyu 53 tyres to yokohama. Straight up after fitment, I noticed how bad the wheels were exposed in comparison to the Jinyus even though both doesn't claim to have any Rim Protect design. These were just so bad. Performance of Yokohama are way better, especially in the wet. I felt very confident on a 70MPH motorway drive in the middle of a cold and windy downpour. Ride comfort is worse than Jinyus- bumpier and way way louder. The stretches where my car used to be absolutely quiet are now producing deafening tyre noise. Just not worth the money at all. Would not recommend them even at a 50% discounted sale!

Given 54% while driving a Toyota Sienna (235/65 R17) on mostly town for 14,000 easy going miles
Absolutely the worst tire in the rain. Even if road is a little wet from a previous rain they can’t grab the road. Even at 25 mph going up a hill unable to grab the road if it’s the least bit slick. I worry about my safety

I bought the tyres after looking Yokohama Made in Japan 4419 built and got on in 2020 but they last only 20-25k. Not a value for money. Having weaker side walls, the tyre blooped out like Dunlop. Not buying again.

Given 31% while driving a Ford Focus MK3 (215/50 R17) on mostly town for 2,000 average miles
Just taken a pair of these off my ford focus. They are probably the noisiest most uncomfortable tires I have ever driven on. Like driving on flat rocks. Changed to some cheap Altenzo sports comforters and the car feels like a car again completely transformed the ride and stance of the car instead of feeling like a dodgem.car down the local fair. Absolute dud of a tyre

Given 41% while driving a Ford Focus (215/50 R17) on mostly town for 7,000 average miles
These tyres on front axle were only 8 months old when I purchased car. I thought yeah Yokohama's that's a good tyre. So far after another 3 months they have not impressed me at all. They always feel flat so much that I keep thinking I have a puncture and they are at the correct pressure. Not a lot of feedback from these tyres either and they are as noisy as hell on any surface. They just feel rather dull. Taking them off soon.

Given 33% while driving a Citroën c4picasso (205/55 R17) on mostly country roads for 10,000 average miles
Had tyres fitted and tracking done in June 2019, Just had my yearly MOT done for 2021 and had an advisory for front tyres. Not impressed as the tyres have barely done 10000mls.

Given 74% while driving a Toyota Prius (215/45 R17 W) on a combination of roads for 60,000 easy going miles
The Bluearth AE50 has a hard tread rubber, which becomes harder with age. While this greatly improves it's durability and longevity, wear resistance, it is thought to reduce it's grip in the wet. The directional pattern does much to prevent this from happening, but many reviewers have experienced wet braking difficulties. That said, I have driven these for 6 months and I have not experienced wet handling problems. There is however a noticeable loss of traction when accelerating hard from standing still, the car's ESC kicks in when this happens. The tyre is quiet, comfortable, corners easily and is enjoyable on long road tours. Fuel economy is typical of these low rolling resistance types of tyre.

Given 73% while driving a Alfa Romeo 156 2.0 TS Veloce (225/40 R18) on a combination of roads for 5,000 average miles
Tyre is set more towards economy than performance but still offers good handling. I was surprised how well it copes in the wet conditions I am driving on coilovers and after replacing the Pirelli P7s I was very much surprised how comfy they are.

Noise getting louder after time.
Overall not bad.

Given 20% while driving a Mazda 3 Skyactiv 2012 (205/60 R16) on a combination of roads for 5,000 average miles
It's a cheap Japanese tyre but not really worth. The poor handling, and wet grip of the tyres had me changed out just after 5000km of usage. I couldn't accept the fact that it have such a poor grip on wet weather condition, which caused the tyre to drift out of the lane and I was lucky not to caught up with other car.

I only used AE50 about 5000km yet into my Nissan E-power Nismo but I think AE50 are nice tyres low noice and with smart grip on the road wet and dry and I believe that these tyres are fuel efficient also and my staering wheel is much more comfortable than before, I believe in Yokohama products

Nice AE50, I have rotation tires every 10k km, current near 90k km & not much heavy noise.

Given 20% while driving a Nissan LEAF Tekna (205/55 R16 R) on a combination of roads for 22,000 easy going miles
These lasted 22000 miles on my Nissan leaf.
I now have 2mm tread on all four tyres, except front passenger side which is down to 1.6mm.
Leaf does have design flaw that causes excess tyre wear due to misaligned rear axle that cant be adjusted.
Anyway I think these tyres are not great and so I have decided to go for bridgestone T005 as replacement as these last well on my petrol car.
I cant comment on grip handling etc as those are subjective opinion and I think affected by many factors, I can only judge wear as this is measured regularly in a scientific way.
