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 Kumho Ecsta XT KU37 Reviews

Given 69% while driving a SEAT Leon FR 2.0 TFSI (225/40 R18 W) on a combination of roads for 2,500 spirited miles
These tires were on the front of my Seat Leon FR TFSI when I bought it and after 2500 miles mainly in the wet I'm looking forward to changing them. Not a bad tire in the dry but do scrabble for grip under hard acceleration and cornering. In the wet the tires lose grip far too easily and fail to inspire any real confidence especially when cornering even on just damp roads.
On the plus side road noise is minimal, they drive well, don't suffer badly from changes in road surface and at least when they start to lose grip it is progressive.
The wear seems average for the use and is probably made worse by the lack of grip.

Given 63% while driving a Hyundai Accent (225/45 R17) on mostly motorways for 0 average miles
Had them when I purchased my Hyundai and got significant milage from them atleast 20% more than the company estimate. My first replacement didn't do that well and so the next time I decided to opt for a more costlier option with Continental. Surprisingly much lesser mileage and performance. Possibly due to the vehicle specs but definitely going back to Kumho next

Given 54% while driving a Porsche BOXSTER 2.7 (225/40 R18 W) on a combination of roads for 100 average miles
These were on the Boxster 2.7 from the used car dealer - previous owners choice. I have only driven around 100miles and they do not inspire any sort of feedback in steering - just hope people behind dont think I am a "granny" Wouldnt buy them myself, having had a z4 with Falken's and they were inspiring

Given 91% while driving a Audi a3 s line (225/40 R18) on a combination of roads for 500 average miles
Only done about 500 miles on these tires so far but I couldn't be happier. Just got sick of putting cheap Chinese tires on my audi which is always false economy.Still getting a bit of road noise,but I still have crap tires on the back so it's probably coming from them. Price wise they are mid range (about £75 each. Haven't found the limit of the grip yet in the dry or the wet as that's not the style I drive. Would recommend this tire to anybody who is after value and quality.

Having bought a Golf R32 these are terrible. These were on the car from purchase, but getting to the point of pulling off for a set of Michelin PSS

Given 90% while driving a SEAT Leon Cupra R 225 (225/45 R17) on a combination of roads for 11,000 average miles
Great tire for the price of £71 a corner. Instantly felt a difference in cornering stability on my Leon Cupra R, from the previous Conti's.
Not pushed hard in the wet yet, but moderate speeds are good with minimal wheelspin.
Deffo recommend as a cheaper contender to the high end tires.

Given 56% while driving a Audi TT (225/40 R18) on mostly country roads for 3,000 spirited miles
Car is very nervous in damp conditions, you can easily lose the front end on roundabouts. In the dry they are good. They have noticeable wear after only a couple of thousand miles, wish i hadn't been tight and bought the Uniroyal rainsport 2s I have on my Golf!

Given 76% while driving a Honda Fit (Jazz) (225/45 R17) on mostly town for 450 easy going miles
fitted these on and had them for about 600kms already. quieter than my previous yokohamas and comfortable as well. gives me decent feedback, probably still new. loads of confidence in straight line driving situations and will update once again as the tire breaks in. overall great value for money and will recommend these

Given 86% while driving a Audi TT (225/45 R17) on a combination of roads for 40,000 average miles
I have Kumho ku37 tires fitted to the front of my Audi TT, I have covered approx 4000 miles on them with minimal tire wear and I feel they perform every bit as well if not better than the Pirelli Pzero Rosso's they have replaced. I would definitely buy them again.
