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.

Top 3 Westlake SA 57 Reviews

Given 76% while driving a Subaru BRZ (215/40 R17) on mostly town for 3,500 spirited miles
Before I start the review I would just like to let you say this is a review for those who are interested in the performance of this tire being stretched. I bought 215/40R17 and stretched it on a 17x9 Enkei RPF1 wheel. I'm going to compare this to the stock Michelin Primacy tires that come with my car that I also stretched on the same wheel. I drove on these tires for my daily commute to work and around town. I only occasionally drove it down a winding road but not pushing the car too hard because of the stretch Similar to the Michelin Primacy maybe just a tad bit more grip. Not tons of grip but the tire has a very stiff sidewall which makes it good for stretching and gives very good road feedback Wet grip is not the best - it did tend to have a bit of hydroplane tendency past 130kph in really wet conditions. (I live in Pacific westcoast so we do see a lot of rain here) Wet driving around town 60-70kph is no problem. Road noise: Tire has a slight hum at higher speeds above 120kph. Not too obnoxious coming from a sports car however if put in a normal car it may be slightly annoying to some. Overall a very good tire especially if you are stretching them. I put them at 40psi and I daily drove it and not once did it debead. For how cheap they are I would say I would definitely recommend them for what they are. Its nothing amazing but for the price its a good value proposition.

Given 76% while driving a Mitsubishi Mirage Hb Gls 2015 (195/55 R15) on a combination of roads for 500 spirited miles
Had these for about a month now and They're OKAY. I go on spirited driving on mountain roads almost every week, and I must say, Grip is pretty good on dry, VERY Sketchy on wet (typical Cheap performance tire) it has a bit of grip but then tends to slide/ understeer. Comfort is meh, as the sidewalls are quite firm, and noise and drone is a bit loud (again, typical cheap performance tire) Steering response and feedback is Sketchy, there are times that the tires does not give Inputs. But you cant beat the Price. Mind blowingly cheap! - Good tires? Ehh.. its not Great, but its not Bad either - Sketchy tires? YES Definitely - Will buy again? Heck YES - Will track it? Heck YES - Recommend to peers with Low Hp mixed with spirited driving? YES - Recommend to peers with High Hp? Eeeeh.. Maybe Not. Go for WestLake sport RS instead - Will it train you to be a better driver? Heck YES

This is my second year using westlake sa57 the value money is really bargain compared to expensive tyre, but this tyre can compete with other premium tyre with budget cost. The performance is really good im a weekend race guys.

Initial Impressions Review
Given 89% while driving a Honda DC2 Integra Type R (205/45 R16) on for 20,000 miles
Have had these tyres since 2019
And they do not disappoint. For the price ibwas skeptical but for a tyre in this price bracket they punch way above. The car was daily driven for three years.. A mix of spirited driving and in traffic. And i am totally blowm away by its versatility. In performance driving they do not fall off with grip when heated up like other chinesium tyres and while the side walls i find to be tough and give a ridged ride I find that as a "performance" tyre it handles abuse really well. I still have more than 30% tread left on them but will be changing them due to age pretty soon. Overall a surprising bang for buck. Unfortunately where i am they are no longer available. I would purchase in a heartbeat once again

Given 86% while driving a Suzuki swift sport (205/45 R16) on a combination of roads for 12,000 spirited miles
Surprisingly good performance from a budget tire. Dry grip is very good. needs a lot of provocation before it squeals. and when it does the break away is quite gentle. also rather good the in wet. the only negative is the hard side walls, which hurts the ride but gives sharp handling. The tires came with the Suzuki Swift Sport i bought. was going to chuck the tires, as Chinese Tires in my mind is junk. but thought i give a a go since it was already on the car. Boy was i mistaken, made me open my eyes and not tar all products with the same brush. I now see no reason to replace them, unless i want a slightly less hash ride. going to stick with them till they hit the wear bars. There are that good.

honestly i was using westlake sa57 around 3 years straight, what i just realize sa57 tyre budget performance Tyre that you are affordable can give you maximum grip especially on track day or daily.

Given 82% while driving a Honda Integra DC2 (205/45 R16) on a combination of roads for 1,000 spirited miles
I've had these tyres for a few weeks now. They are pretty decent for the price. Corners well and handles pretty good in the wet. Down side is the side walls seem to be very firm. They do not soak up bumps well. Road noise I can't really comment on as I have an exhaust fitted but for the most part they aren't noisy to me.
