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.

Best resistance to aquaplaning, good comfort, acceptable in the dry.
Long braking distances and poor handling in the wet, very high rolling resistance.
Conditionally recommended.

Top 3 Nankang AS2 Reviews

Given 94% while driving a Audi A6 Avant 3.0 TDI Quattro (265/35 R20) on mostly country roads for 4,000 spirited miles
Wet grip -amazing
Dry grip - amazing
Snow - bloody decent
These tyres blew my mind, these are now my GO TO tyres for my cars.
I live in the Highlands so wanted tyres for my A6 daily Quattro diesel that did both very wet and dry. Well, in the wet they are Phenomenal, the car Is like glue on wet bends, hitting puddles etc etc. They ooze reassurance and give you better confidence and safety.
Yes it's a Quattro but, previous pirellis just lost traction in certain situations. I
t handles amazing, never once lost slightest grip and they feel so stable.
In the dry, again phenomenal. They really gel to warm tarmac. Road noise is minimal too!!

And, BONUS was that they performed damn well in heavy thick snow which I was not counting on, they plough through I think partly to the huge channels in the tires stopping the tread compacting with snow but don't use for that reason haha. Highly recommend these they are amazing.

Given 73% while driving a BMW 640d (275/30 R20) on mostly motorways for 3,000 easy going miles
Fitted to a 640d.

Don't push my car to limit in corners, had no issues from them in wet or dry.

They do struggle under initial load when launching in wet and dry though, which is understandable in a high-torque RWD vehicle.

Unsure on wear yet, 3k miles in and still looks new.

Given 67% while driving a BMW X5 (275/40 R20) on mostly motorways for 5,000 spirited miles
feels good everywhere with high speed over 220 kmh the straightrun is not good enough, and i suspect it is because of the (soft) tyres

Given 43% while driving a Volvo V70 2.0D (225/50 R17) on a combination of roads for 15,000 easy going miles
Very disappointing wear, changed all 4 tyres after less than 15,000 miles, handling average, wouldn't buy again

Given 96% while driving a BMW 320d XDrive saloon (265/35 R20) on a combination of roads for 0 spirited miles
My first experience of Nankang tyres and I have to say I am really pleased. Would normally buy a premium brand but these came on the car and have pleasantly surprised me. If anything the car is “over” tyred as not standard rims but wet or dry it is predictable and sure footed even spirited driving through local lanes which I do regularly as well as many motorway miles. I’m replacing like for Like as the price is incredibly good and I need nothing else from my tyres.

Given 80% while driving a BMW 520d (275/35 R19) on a combination of roads for 500 average miles
I drive a BMW 5 Series (17 plate) & rear runflats are expensive as I have 19'' wheels. Tried Falkens and was very happy with them but my local garage said try these.....and so far so good. These are big tyres being 275 wide - cost wise £170 each fitted which is very good for Runflats of this size 19''. Drive seems fine / noise, no issues / wet handling not really tested so far but roads were wet this morning and had no problems, they are A Rated for wet so should be ok....wear only time will tell but as I'm retired my days of pounding motorways are over but I still enjoy driving my car and tyres are very very important.......yes you get what you pay for generally but you can also get good value and to date these Nankang's seem good value for money.

Given 60% while driving a Ford Focus ST 225 (2003 2007) (225/40 R18 W) on mostly country roads for 100 spirited miles
Incredibly unstable due to the large water channels in the threads - making the rubber inbetween quite thin/small, and it flex. Very noticeable in high speed atleast and during hard braking, car squirms like a snake. And if road is uneven you have to countersteer for each lean the car makes. (by a small amount of course but noticeable)
Maybe not so noticeable on cars that already have this character due to soft suspension and high profiled tyres etc.

Given 89% while driving a Ford Mondeo Titanium X (225/45 R17) on a combination of roads for 16,000 average miles
Bought these at half the price of the main brands (my tyre size was coming in around £200 each for most makes).
To be honest, I've notice no difference in handling, grip or stopping ability at all compared to the 2 previous big brands I had.
And so far they've lasted twice as long on the front compared to the last pair.
Noise levels not bad either.
