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 Star Performer TNG UHP1 Reviews

Given 35% while driving a Mercedes Benz Vito (255/45 R18) on mostly country roads for 8,000 average miles
Cheap tire. They are dangerous with speed over 120km/h. The car dance by itself and hard to control even if it is a straight line. If you want to chat inside the car, forget it as the noise is to loud.
The wear on the side is crap.
Worst tire I ever have owned.
Now I have changed to GoodYear Eagle F1 AS3, and what a differnce.

PS! If you don't like a big challenge, never buy these tires

Given 83% while driving a BMW 330 Ci Sport (245/35 R19) on mostly town for 4,000 spirited miles
Put to test 235/35 and 245/35 R19 Star Performer tires. Indeed, very similar to Nankang NS-2.
Very great looking V shark tread, rim edge with protection lip, nice smooth. Stretches well.

Dry grip excellent, can't complain. Wet grip is pretty ok, could be little better... but for this price it's great.

Given 73% while driving a Opel Zafira 1.6 comfort (225/45 R17 H) on mostly country roads for 500 spirited miles
NOTE: available in H and V speed ratings on same tire sizes.
I'm a tight-wad, and spent ages trawling through brand new cheapy tires on eBay trying to sift through all the junk and find a reasonable set to go on a family wagon (Vaux Zafira A) and these came up at a fantastic price of just £42 a tire delivered to my door.
First impressions, they look very similar to the Nankang NS2's and have a good sturdy tire wall that sits up and over slightly the rim edge giving rim protection.
They are not as noisy as I thought with them being directional and was expecting tire hum on smooth road surfaces (the kind of noise like a wheel bearing) but was pleasantly surprised.
I do a lot of miles, city and motorway driving is smooth and sweet, dry grip is good, wet grip is good (haven't slid them sideways while accelerating at full lock like I could I usual cack tires)
These are a great choice for those who want cheap tires for domestic vehicles. I'm really pleased as they have all thr pro's of the Nankang NS2's without the cons.
A good upcoming tire brand.

Given 50% while driving a Honda CRX Del Sol (215/40 R17 V) on mostly town for 10,000 average miles
It is cheap, but therefore dangerous, from 88kmh with my honda del sol, I can stop in 50-52 meter(measured, dry), but with a better(not premium) tire the distande is only 36 meter(measured)
Buy some good tires, not this one!!!!
