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 Sunew YS618 Reviews

Given 13% while driving a Toyota Celica VVTi 140 (205/45 R17) on a combination of roads for 1,000 spirited miles
Lethal in wet conditions ... slow pull offs and the car is wheel spinning Roundabouts you can feel the car moving around and trying to slip into the other lane under slow speeds. Small puddles and barely any surface water and the tires are done. In the dry they are tidy however i would not push to far.

Poor braking distance, lots of understeer, dangerous in the wet

Garbage! Don't hold a seal, so have to pump tires up constantly. Wear is shocking. New to used in less than 6 months, average mileage a week. Handling is poor, makes car feel like a boat. Never again!!

Given 39% while driving a Ford Mondeo estate (225/45 R17) on a combination of roads for 1,000 average miles
Supplied as new during MOT failure but just discovered were already 2 years old when fitted. Outside walls cracked after 1000 miles and 1 year but passed the MOT in 2 stations. Car has been SORN for eight years now they are 10 years old still hold air and support the car but they look very deeply cracked falling apart like I image a re-mold/re-tread might. I would never buy again. Replaced with part worn trusted well known brands as I always do when given the choice for low mileage use.
Always check the tire date code when you buy a tire, check it for bulges and side wall damage. Never rely on a retail chain to fit you a good choice of tire, do some research.

Given 30% while driving a Renault Megane R26 (225/45 R17) on mostly country roads for 0 easy going miles
Had two of these tires on the front, nearly binned it going round a roundabout at 15mph. Safe to say I'm buying new tires ASAP. Do not buy.

Really good tires from my experience, have had them for a year now and have done about 7000 miles on a mixture of roads, Still have plenty of tread left. Came from Goodyear tires and struggled to notice the difference. Would definitely buy again and recommend.

Given 54% while driving a Mercedes Benz C220 CDI Blue Eff. auto (225/45 R17) on a combination of roads for 11,000 average miles
Tires were fitted on rear of car when I bought it from a Mercedes dealership. Have driven 11,000 miles on them since February 2017 across all sorts of roads from single track country lanes to motorway. No noticeable problems in the dry and the tread on the tires is still great. However, in the wet they give no confidence at all with the rear end sliding around when going around a roundabout in particular. Although there seems to be many miles left on them, they are being changed for Continentals tomorrow as I'd rather stay alive! Quote from a private tire fitting firm I've dealt with for 15 years - 'I wouldn't fit them to a wheelbarrow'. And that was before I told him about the sliding!

Awful tire. Grip was almost non existent. Rear end of family estate started sliding out on a slow large roundabout and I'm a cautious driver! Wife and family weren't impressed. I've never experienced a tire this poor, they adversely affect your confidence driving. Had them removed for Sailun Attrezo's (impressive tires). These are a false economy, steer well clear.

Brought car 4 months ago from networkQ tires have lots of tread but ride is a tad firm but road feedback is ok but they are quite noisey on the motorway.Will look at tire reviews site when I change tires again.

Given 40% while driving a Audi 1.8T Quattro (225/45 R18) on a combination of roads for 3,000 average miles
Bought these tires on alloy rims for my wife's Audi TT three years ago, so conveniently outside the warranty. I replaced the first one in Nov, 2015 and have just replaced the other three due to delaminating of the sidewalls along with significant splits etc. These tires have done less than 3000 miles. Steer well clear, I think these tires are dangerous, they may be cheap but not worth the risk.

Given 41% while driving a Vauxhall (225/35 R18 W) on a combination of roads for 2,000 easy going miles
Bought my car last year from the dealer which came fitted with these tires on the front.
Firstly the Dry - they are actually not too bad, they provide good traction and not bad grip as long as the weather is above 10 degrees or so. If its colder they start to struggle. Even when out for a nice spirited drive on a sunny day they perform pretty well actually.
Now the Wet - Wow, where do I start. Absolutely useless in the wet. 10MPH and the front end sliding almost into other cars on large open roundabouts is not fun at all. Taking it easy around town pulling away from junctions and roundabouts is shocking. They are even worse than above its its only slightly wet/damp conditions.
Wear - Had them on for 2000 miles and there is still 7mm of tread across both tires with no visible damage or cracking/splitting at all.
All in all, they are what they are, an Imported summer only tire that people/garages fit over here for cheapness. Wouldn't ever buy again.

Needed new tires for my Corsa VXR so as money was tight opted for these budget tires....NEVER AGAIN!!! After only 1500 miles both front tires have severe cracking on the inner walls!! These tires are dangerous and should be taken off the market!! Buying these is definitely false economy as I am now having to buy proper tires after only a few months! If you value your safety DO NOT buy these rubbish tires!!

I would not recommend this brand if you care for your life. If you want to put yourself, your love ones in danger or other people that may get involved if this tires blow up, go ahead and puchase them. Only had few miles on it you can see the crack on both sides already, of my four tires! Waste of money dont buy this crap.
