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.

For this price, this is the best value for money.

Given 10% while driving a BMW 525d E61 Touring M Sport (225/40 R18) on mostly motorways for 0 average miles
I drove this tyre a bit faster yesterday, with 2.9Bar of pressure in it. Tyre is 6 years old. At some point I was doing 90 to 100 (150Km/h) And the car just started vibrating heavily. One of the rear tyres seemed to have lost its form. I never had this before in my life. Never again will I buy this tyre.

Given 73% while driving a Mercedes Benz (255/45 R20) on mostly town for 16,780 easy going miles
I replaced all the four original Pirelli Scorpion Verde MOE Run Flat tyres (255/45R20) tyres on my Mercedes Benz GLC250d (year 2018 model) in October 2021 with only 27000 kilometres clocked with four Kingforest KF550 tyres and now the two front Kingforest tyres had to be replaced, at 47110 kilometres. All the other areas of the Kingforest tyres are good except tyre wear: having to be replaced after less than two years and just 2000 kilometres.

Given 39% while driving a Volvo S40 2.0d (205/55 R16) on mostly country roads for 12,500 average miles
A tyre that I never will make the mistake and purchase again. It were not as cheap as the grip suggest. my suggestion to everyone interested in these tyres there are outer manufakturs that are cheaper and a much better buy.

Given 81% while driving a Toyota Vios (215/40 R18) on a combination of roads for 10 spirited miles
Since Ive shifted from R17 to R18 on Toyota Vios Gen3 modified, my Kinforest Tyres prove dependable in tight corners on wavy concrete roads. Id been averaging 4,000 kms drive per month mostly highway sprints. I love the riad grip. By far, my favorite tyres until other tryres will surpass the quality.

Given 49% while driving a BMW X5 (315/35 R20) on mostly motorways for 16,000 easy going miles
I bought these tires for my X5 4.8is because the old tires were worn and there was a bulge. I didn’t splurge on premium tires because my intial intention was to flip the car and make money. Long story short, I ended keeping the car and stuck to the tires. About 25,000km, these tires were well worn to the legal limit. It performed well in the dry. Perform almost as well as a premium tires in dry but dangerous in the wet. The noise level was a little noisy but not too bad. The wet weather performance was apalling and disappointed in the tread life. I would not recommend this tires and would not buy again. There were quite expensive in the first place. I would instead try a different tires

The worse tires ever can buy. Rather drive on the rims. Atleast u know ur driving on rims. Not hope u have a good tire and learn the hard way they suck and will leave u stranded.

Given 86% while driving a (235/35 R19) on a combination of roads for 12,000 spirited miles
I have had the 235 35 19 on a VW Golf 4 Motion Sportwagen for 2 summer seasons. I previously had Michelin 4S. While they are not the 4S, they are also not that far behind. I do not track my car, but I would say I am an enthusistic driver. After 12K on the tires they are still handling very well and still really quiet. I am looking at ordering another set ... big bang for your buck with the kinforest tire.

I was amaze by the performance of this tyres. Thinking at first that cheap tyres is just a waste of money but this tyres never disappoint my me. Comfort and handle well if your driving your car daily.

Given 100% while driving a (225/45 R17) on mostly town for 50,000 average miles
I have had these tyres for 2 years and they’re performing much better than more expensive tyres I’ve had in the past (Bridgestone, Kumho). These are very high quality tyres and would highly recommend.

Given 83% while driving a Hyundai Veloster Turbo 1.6 TGDi (235/40 R18) on mostly town for 50,000 average miles
Have these tyres since 23000km and 43000km on my Hyundai Veloster (2 tyres for each change). Never had any problem on both dry and wet roads. My mileage is now 110000km and the tyres still got about 10% (at least) tread remaining. But now after about nearly 80000km and 7 years on average, the tyres get a little noisy. This is to be expected due to the rubber hardening. I'm looking forward to another new set of Kinforest 245/40/18 for a more snug look. Pretty much worth in value for money at about 3/5 to 2/5 the price of more "branded" tyres.

Given 60% while driving a Ford Mustang (225/40 R19 W) on mostly country roads for 10,000 average miles
Good tyre for the price. The grip felt good in dry but I didn’t push it, road undulations seem to unsettle the tyre. Some wheel spin noted on occasion even when not accelerating with full power. In the wet drove carefully as I didn’t have confidence in the tyre. Drove well around town and motorways. One tyre blew out when I hit a small rock at low speed. Sidewall burst. Overall I wouldn’t buy this tyre again, but if budget is an issue, then yes but would drive more carefully than usual.

Given 84% while driving a Mercedes Benz C350 RWD (225/45 R17) on a combination of roads for 6,000 spirited miles
I've had these for several months and now changing the rims from 18 to 19 and will buy these again. I have done some high speed driving, sharp high speed cornering, sharp braking, even some burnouts and they handled everything great. They are now half way down but considering my aggressive driving I'm not surprised. From what I see I could still go for one or even two moderate driving seasons. They are a bit slippery on wet but not too much, they still do a great job especially for this price.
