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 43% while driving a Audi S3 (235/35 R19) on a combination of roads for 2,000 spirited miles
Audi S3 Cabriolet 2016. Had these on the car when I bought it, they look the job but found the dry grip was ok but a bit squirmy when under pressure. The first time it rained these showed their true colours! Awful bordering dangerous, they left my rear end sticking out on a roundabout even on a quattro S3. My first job is to get these off and replaced with some Michelins or Bridgestones. I can't believe how bad these are in the wet. DO NOT buy these, you will need the grip at some point and you will not have it.

They are tires for everyday normal use in everyday cars and not for fast or improved ones. And for the roads here, no tire is good...they are miserable.

Given 32% while driving a BMW 320 d (225/50 R16) on a combination of roads for 200 easy going miles
Do not buy this tire if you value your wellbeing! I fitted to 320d rear, the whole rear ended twists under load. If you cross a white line the tire deforms and try’s to put you in the hedge even at 50mph! If it wasn’t for dsc I’d be dead already. It comes to something when your 13 year old in the passenger seat can feel the whole car wallowing like a boat! These should never be allowed on the road. Please do not buy!

Given 42% while driving a Vauxhall Corsa 1.4T (215/45 R17) on mostly motorways for 16,000 average miles
Had these fitted by a "cheap" garage that my mum liked to use (cheapskate) Ended up charging me £400 for 4 of these things to be fitted Seriously cheap, wore down quick and although i hadn't lost grip in the dry, in the wet it became obvious. After 2 years the front 2 tires are down to 70% wear. Replaced with some quality Michelin P4s', £200 fitted in my driveway, miles better grip! Will be getting rid of the rears soon.

Buy this brand and use it almost a year then the tire has lump in 4 tires. Not recommended since my car just barely used for long travel and only use to pick kids from school.

Given 64% while driving a Mercedes Benz SLK 230 (245/40 R17 V) on a combination of roads for 35,000 average miles
Well. I’m pretty sure I reviewed these two years ago when I thought they might be near the end of their life... here we go again. These two pieces of volcanic bedrock were on the rear of my SLK230 when I bought it in 2017 and had approximately 5K and 6 months of use already on them. Fast forward to today: 26th of August 2020. Three and a half years have passed, 35000 miles have been slipped/slid/burnt/tumbled through and I’ve have my third MOT with no advisories aside from ‘worn rear tires’. These things are made from armor-grade depleted uranium and hold in the wet as you’d expect being made from a material harder than the compressed centre of a dead star. In dry they are acceptable. In the wet they will continuously try to murder you in an admittedly progressive and slidey fashion. For the price; I’d put these on any non performance car simply because they’d outlive the driver. For any vehicle with the capacity to do 0–60 in less than an epoch I can not recommend at all.

Given 52% while driving a Toyota iq (225/45 R17) on a combination of roads for 100 spirited miles
I read some of the reviews after I'd bought a full set of these tires for my daughters car, nearly passed out some of them were so damning. Went home and drove the car myself expecting it to have turned into some sort of drift machine, but no, surprisingly it hadn't. Must just be the wet driving I thought...so after a decent bit of rain...which is common in Northern Ireland I took it for another blast on wet roads. Gave it plenty both into, round and out of roundabouts expecting to end up exiting on the other side of the carrageway...but no It wasn't that bad. True the car did drift a couple of feet outta line, but never let go. Lest just say I was well over the 30mph limit through the roundabouts and lived to tell the tale...yep on wet roads too. In summary these arn't the dearest tires on the market they're a budget tire so don't expect outstanding performance. They're not lethal at all and for the everyday driver, just fine. Would I buy them again....we'll see...!!

Bought these tires thinking they would be like any other tire, hell was i wrong DO NOT BUY THESE TYRES my car swerves on motorway and feels like im in a boat Very dangerous especially with kids if you are suicidal it makes sense to buy them and you will save a bit of money also but if you want to have a few years of life please avoid your traction control will also be working overtime, i have had them on my car 1 week and have ordered new pirellis in will be changing today.

My zeta ztr10 tires are very well in the wet and dry and the road noise is almost non existent and I drive a hybrid so that's a big plus for me. My overall experience with the zeta tires are amazing and I would recommend them.

Given 40% while driving a Subaru BRZ (225/45 R17) on mostly country roads for 500 average miles
I recently bought a used Subaru BRZ and the dealer replaced the worn OEM Michelin Premacy rear tires with a pair of Zeta ZTR10's.
In short the only tires I can recall that provided such poor handling and feedback were a set of cheap remoulds many years ago. If these are a cheap tire they may be OK for a shopping car, but don't put them near anything sporty. They'll be coming off as soon as I can decide whether to replace just the tires or go for a new wheel/tire package.

The longer version :
when cornering these made the car feel as if the side-wall was flexing under the lateral load, or as if a bush was worn. When I eased off slightly, it returned to shape. Attempting to take a moderate sweeping bend with any enthusiasm had the car tracing the path of a 50-pence piece.
As an experiment I rotated the wheels to have the Zeta's at the front, worn Premacy's on the rear. Now the rear was stable, the front vague.
As a further experiment I used a set of old wheels with old and worn no-name tires and even they were noticably more stable and communicative then the Zeta's.

These are on my 2009 MX-5 Miata and I have been driving with them for over a year. Handling is not as good as the premium tires like Bridgestone Potenzas, etc., but for the price they are a steal and well worth it for street use.

Drove 2200 miles in the Swiss Alps and down to Italy then back home to the Uk in my BMW Z4,did the Stelvio pass and the tires performed admirably.. they are still new so I can comment for them when the get older or worn but they were good on this road trip

Given 26% while driving a Mitsubishi Mitsubishi Shogun 3.2DiD SWB (235/45 R18) on a combination of roads for 2,000 average miles
I drive a Mitsubishi Shogon I had the set of dunlops that were on the car when bought new from the dealer after 55k miles i had a set of zetas fitted but the chap that deals with the company cars. I always drive in permanent 4x4 and in the previous 2 years never once seen my traction control light come on. Que the zetas my traction control was like a pilot light it never went out. In the dry they didnt fill me with confidence and made the car twitchy. In the wet they were a real threat to life. I am not a boy racer and these would skid me on to the wrong lane going round bends. I complained several times to te garage that fitted them, with no joy the final straw they spun me on a slip road in to the barrier. I cannot believe these are allowed to be sold, quite simply the most dangerous thing ive drove with in the last 20 years

Given 46% while driving a Ford Focus MK3 (215/55 R16 V) on mostly town for 2,000 average miles
Had two of these tires fitter by the previous owner of the car. Grip in the dry was average, but I never felt fully assured on twisty roads. In the wet, the tires were awful, causing wheelspin at the front with less than 1/2 throttle, and giving me pretty poor braking performance. I decided to get them replaced with some Uniroyal's before winter.
I never really noticed much noise with them at least.
