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.

165/65 R13 • 2011
4th/4
Surprisingly good in snow thanks to a blocky tread pattern. Fairly comfortable.
The Nexen SB652 was the cheapest tyre on test and it shows. The dry grip is average, the wet grip can be terrifying and it always leaves you second guessing as to whether it will grip or not. Not recommended.

Given 87% while driving a Peugeot 205 (175/65 R14 H) on a combination of roads for 6,000 spirited miles
The Nexen SB650 in my case is an absolutly fantastic tyre. I always insist getting tyres with 4 grooves for max steering performance as my car tragically has no PAS and, and another big AND, better distribution of the braking force. This tyre is very good in the dry and makes the car handle to its absolute razor tipped edge during "spirited" driving. They wear quite badly though but it just suit the car like cashmere gloves to hands.

Given 59% while driving a Ford KA 1.3 (165/65 R13) on a combination of roads for 20,000 spirited miles
End of life report - they lasted 20,000 miles on the front of a KA, where other tyres have only lasted me ~12,000 miles.

Pretty average dry grip, and wet grip is even worse, but they are awesome snow tyres. Must be the big blocky tread pattern.

Replaced with Toyo 350's which have so much more grip wet and dry it's unreal. The toyos are only a few quid more. I'll report back once I know how they're wearing.

Given 81% while driving a Maruti Udyog Wagon R (225/45 R17) on mostly country roads for 0 spirited miles
The handling of my Wagon r has improved amazingly after I replaced MRF Z-vts tyres with nexen SB 652.. Dry braking has improved many folds and I feel the vehicle in perfect control even above 100s...

Amazing product as of now.. Have to check its durability wrt to wearing..Hope it would also impress me..!!

Given 79% while driving a Ford KA 1.3 (165/65 R13 T) on a combination of roads for 12,000 spirited miles
'Bit' of a car nut and have paced this tyre under allsorts of conditions. Finished off a front set in around 9,000 miles due to worn outer edges but I do work them hard alot of the time. Rears are blistering on the outer edges after 10,000 and tread is slightly worn.

In the wet the grip levels are modest but feedback and feel is really rather detailed and with no ABS on my car it makes it easy to judge and feel the start of an inside front locking up or the back squirming around. Oversteer is progressive and easy to feel and catch when it gets a bit lairy at speed e.g. 50/60 mph.

In the dry decent grip can be had even when pushing on. During 'highly spritied' driving down lanes etc they let go in a gentle slide when pushed though dont give as much detail as in the wet. Having done a track day with these they lasted 3 sessions at max attack with no sign of wear or noticeable handling change.

Overall a bloody good tyre for what it is too be honest. If your after a budget tyre and like your driving at all, i'd recommend this!

At ?33 a tyre FITTED I really can't argue with the price. They don't feel quite as grippy as the Falken SN828's that they replaced but they're a bit more comfortable and hopefully they'll last a little longer.

Not the prettiest tyre or the grippiest but they're nice and comfortable, perfect for a floaty KA :)
