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 30% while driving a Audi TT (225/45 R17) on mostly country roads for 20,000 average miles

Given 44% while driving a Volkswagen GTI MK5 (200) (215/35 R19 W) on a combination of roads for 9,000 average miles
Bought my Golf MK5 GTI witht those tires. This car has 200HP. In the dry they have some grip but in the wet the traction control has to kick in every corner. Also with those tires it feels like the car is floating. The wear and price is good, but if you like to have a safe drive, dont buy those tires!

Given 84% while driving a Audi A3 (225/45 R17) on a combination of roads for 6,000 average miles
Had these tyres on now for about 6 months they have done 6000+ miles, I have found them a very good tyre, showing no signs of wear at all.
They are however slightly more noisy than their replacement but Radio 2 takes care of that,would use them again to replace the rears that are wearing now.
I have not encountered some of the problems re wet weather grip like some others have, there again I dont drive like a "lunny", perfectly good tyres and excellent value for the price £44 fully fitted at Lindleys Arnold Nottingham, who I reccomend very highly.

Given 80% while driving a Ford Mondeo Titanium X (235/40 R18 W) on mostly motorways for 40,000 average miles
Reluctantly purchased 2 for the front as a temporary fix. Noticed lack of wet grip compared with previous continentals and initial ride seemed spongy. I noticed no difference in fuel economy. Was less worried about punctures given the low cost.
Dry grip has been excellent and wear has become a talking point. These tyres are just about to pass 40 000 miles (more than I have ever achieved) and that is on the front. They are just off the wear markers so time to replace. These were nearly a third the cost of a premium brand and for me they have been outstanding value for money. I might have been lucky though - if the reviews vary the quality might vary too. The older Continentals on the back are also still going. They must be getting on for 50 000!

Given 47% while driving a BMW 328i (215/45 R17 V) on mostly town for 5,000 spirited miles
First you have to consider the going price for them, almost half of a decent economy tyre and a THIRD of a brand name high perf. So on that basis they are OK on the dry, if you dont expect laser steering and mega feedback. I suspect high levels of silica on the compound although they do not ride hard at all. Noise is kept in check too, and they can take a good pounding(think big pot holes)without ripping apart.

In the wet is where it all falls apart. You just have to relearn how to drive and keep speeds down (especially in RWD).

All in all, really cheap "decent" +dry weather tyres that are not going to give you any thrills neither break the bank. Also, due to the cheapness, awesome for hooligan driving ounce you learn their limits.

Given 27% while driving a Opel Astra H CDTI (225/50 R17 W) on a combination of roads for 2,000 average miles
I had no choice in this purchase, lease company did that.
Believe me, driving 1000+km's per week allows a person to develop a sense for the behaviour of the car.
These tyres left me feeling like I was floating on a foam-rubber surface!

If you HAVE the choice, please do yourself a favour - Choose something else!

Given 47% while driving a Ford sportka 1.6 (195/45 R16) on mostly country roads for 500 spirited miles
I got these tyre put on when I had the car serviced, previously I had toyo proxes fitted to the car and even worn to a couple of mm of tread they had much better grip. The sunnys are so so in the dry, though are much more likey to let go as you near their limit. The sportka has no traction control so mechanical grip is a must, but with the Sunnys I have found the wheels spinning pulling out of junctions or round roundabouts even in the dry, something that shouldn't happen as the car only has 95hp, and something that never happened on the old tyres. If the road gets damp the grip levels drop off pretty quickly, braking is worse in a straight line but only a little. Mainly the problem is cornering where the grip levels are generally not great and the tyres can let go without much warning. Would not recommend to anyone with FWD for the front wheels of their car, you might get away with them on the rear. Could be ok for something like a RWD saloon doing motorway miles.

Given 80% while driving a Honda Prelude (215/45 R17 W) on a combination of roads for 14 spirited miles
I got these tyres as i need it some very cheap tyres, because i was very tight on my budget. I was very surprised by these tyres, very good road holding in dry, good cornering speed, better then average on wet roads, and in ireland its always wet. They arent as good under heavy acceleration on wet, my car just goes side way if i accelerate from roundabout heavy in wet. I drive 225bhp fwd car, and like to push it a bit. Mite be good on less powerfull cars. In recent snow they were very slippy. Iv done 19 000km, and wear is very good, but ill be changing them for uniroyal rain2, or conti sport 5 sometimes soon.
