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.

Given 90% while driving a BMW 335i (225/40 R18 W) on a combination of roads for 5,000 average miles
I had 4 Race 1 Plus tires and Keskin alloys fitted to my BMW 335i. I have done roughly 5,000 miles so far and they still look like new. I only needed one wheel for my BMW as it had a crack (common fault) but the price for the 4 Syron tires and Keskin wheels worked out cheaper in the long run than 1 original BMW rear wheel and a Bridgestone run flat tire. I also had a set of Syron semi-slick tires fitted to my Ford Fiesta which performs outstanding in the wet for a semi-slick .

Given 70% while driving a BMW 320d (255/35 R18 W) on a combination of roads for 1,500 spirited miles
nice tire, as size 255/35/18 for my BMW rear wheels. it does look nice , grip is ok in dry/wet, not for sporty driving in heavy rain thought ( had lots of wheel spin) BUT BE AWARE IT IS HARD RUBBER, TOOK TWO GUYS AT GARAGE TO MOUNT IT ON 18" j9 WHEEL AND I GUESS HARD RUBBER IS CAUSE OF LOTS OF ROAD NOISE, SORT OF ROLLING NOISE, NOT SURE YET NEED TO CHECK BALANCING....

Given 96% while driving a SEAT Ibiza Cupra TDi (205/40 R17) on a combination of roads for 5,000 spirited miles
Bought these as I have heard a few good words and by god they are right. I have Toyo proxes T1R on before these and i feel safer with them straight away! Done around 5000 miles and they have plenty of tread left. In the wet/damp they handle amazing and even better in the dry. Little bit wheel spin from a standing start but you'd expect that with a fast car. Aquaplaning is a thing of the past, no twitch or nippy bum time with these!

Given 83% while driving a Mitsubishi Evolution (225/45 R17) on a combination of roads for 400 spirited miles
Bought these Tires about 3 weeks ago now, was a little unsure due to owning an Evo 9 FQ340 remapped to over 400 horses as always used Eagle F1, Bridgestones or pirellis. But my god do these stack up, not only do the price considerably out match the others they handle Just as good if not better in some cases. ok track maybe not!!. but road use, not once yet have a twitched on cornering "remember Though i have ayc 4x4" but still they have done me proud and def buy again.

Best tire i have had fitted to the sc430 amazing grip in dry and wet and very little road noise . these are not cheap tires these are quality german tires at a good price ... why spend double the price for a 'brand' name tire when these are better

EDIT: I don't know if these tires still exist, but I had a flashback to my experience over a decade ago and couldn't let my below review stand in good conscience. Once I had travelled around 1,000 miles on these tires and experienced rainfall, they nearly killed me. I rounded a corner at a perfectly normal speed to find my traction control light flashing frantically; I suspected oil/diesel on the road, but as I continued to drive, I found the tires had such terrible lateral grip that I pulled over to check tire pressures (I remember the shock so vividly). It was only a few hundred miles later that I had to bin the tires and replace them with Goodyear Asymmetrics, and I learned never to take a chance on unknown tires (or trust reviews of new, unworn tires) again - at best it costs you in insurance, at worst it costs your life! Only trust reviews where the reviewer has put over 1,000 miles wear on the tires, THEN driven in wet and cold weather. The BBC did an expose on cheap tires failing miserably after they wore through 0.5-1.0mm of tread, no longer testing anywhere near as well as their official test performance. Wow, excellent tires! Replaced my Dunlop Sport SP01 run-flats at the back with these and they are amazing. Although I've only travelled around 500 miles on them the winter performance is outstanding. Not even a hint of wheel spin under maximum acceleration, even when it's -2. Accelerating off a roundabout or leaving a junction is also much better than the Dunlops.
The tires to have a tendency to tramline although this can be almost eliminated with a few extra PSI. The extra wide tread pattern disperses water as if it wasn't even there.
Treadwear is an unknown at present, having only travelled 500 miles but even if they only last half as long as the Dunlops they were less than 1/3rd the price!
My advice is to try them at manufacturers recommended pressure and if the sidewalls move slightly on heavy cornering, or you feel the car following ruts in the road, add 2-3psi and try again.

Given 97% while driving a MG ZS (205/55 R16 W) on a combination of roads for 500 spirited miles
Just fitted this tire but grip, steering response, feed back etc are excellent. The tire is particularly good for comfort and reduced road noise, compared with the previous tires and eliminates the niggly ride common on this model without loosing the firm positive response.

i brought the set of tires last year online (and very competive price) they have done approx 7/8000 miles i still have a good amount of tread on them i was amazed how quiet the tires are as i took off goodyear eagle f1's which a found good but noisy on the motorway.I would definatly reccomend them i took a chance as they havent been out long and found that they are better than my previous tires and saving of £96 on the total cost was a bonus i have now put them on the wifes fiesta too (she had contis on) if you are thinking of getting a good tire at a reasonable cost i would say try syron.
