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 Hankook OPTIMO K415 Reviews

Given 100% while driving a Nissan Maxima ST (215/55 R17) on a combination of roads for 60,000 average miles
Used in A33 Maxima FWD for almost 100k kms on NZ roads. Excellent in both wet and dry conditions. Used a family car and never had any issues driving in heavy rain. Not driven in snow. Never had any issues and no uneven wear as well. Got wheel alignment and balancing done when all 4 tyres were changed and it lasted almost 100,000kms. Highly recommend.

Given 73% while driving a Kia Motors Sportage (235/55 R18) on mostly country roads for 42,000 easy going miles
Now covered 42k miles and 5mm still remain, can't seem to wear them out. Think that hankook has stopped making them now which is a shame. No problems with braking in wet or dry conditions. .

Given 90% while driving a Hyundai ix35 (225/45 R17) on mostly motorways for 40,000 easy going miles
Used two times on two different Hyundai Tucsons: 1st 2012 1.6 GDI lasted over 60k kms, second Tucson again 2014 60kms again. Reasons that I quit observing kms was that I sold first at 60k km on the clock, second I had to replece them with winters.

Given 100% while driving a (225/55 R18) on a combination of roads for 2,250 average miles
I just had new tires installed on my car. I did a lot of research. I couldn't find an economical tire. The branded ones were too expensive. I saw the Optimo brand at the tire shop. It's really great. Economical. I used it. Excellent in every way. No need to spend a lot of money. I recommend it.

Have driven 32k miles on these, fronts are down to 4.5mm rears 5.5mm expect to do at least another 10/15k before they need replacing. Have swapped back to front each year. May look for slightly quieter tyres next but can't fault the wear.

Given 50% while driving a Toyota aurion (215/55 R17) on mostly motorways for 0 easy going miles
Please do not buy this tyre, Hankook claims are not true, warranty is not worth what is written, my wore out barely 17k mostly freeway driving and not what they claim. Also purchased 6 hankook tyres for a small truck, ten years ago and only lasted 12 months. Hankook has lost me as a customer.

The tires were fine. They kept the wet well, dry too. The brakes held well.

Given 93% while driving a Hyundai ix35 (225/60 R17) on a combination of roads for 35,485 average miles
I bought an IX 35 September 2015 with hankook optimos K415 tyres as original equipment. In the wet & dry the grip is excellent as they were in the snow. The car is easy to control in high cross winds as well.the tyres hav'nt suffered from potholes etc. My daughter ,myself & wife drive the car in that order motorway & town but not off road even though it's a 2lt. Automatic 4x4 I am ready to replace the front tyres soon ( 2mm) rear (4 mm) as of today the mileage is 35,485 miles ( not kilometres) we are not “boy racers” but I do know my daughter likes to go “ fast “ when she's on her own .

Given 18% while driving a Peugeot 306 GTI6 (195/55 R15) on a combination of roads for 25 average miles
Hankook Optimo K415 tyres are really not good, I really wish I'd gone with another make but after reading the reviews on here and the rubbish on their website I thought I'd buy them.
Never again will I waste my money on Hankook tyres, I tried speaking to Hankook and all they did was palm me off. Terrible road holding, no feedback and my car feels like it has jelly on all 4 corners.

Very good tires, comfort, low noise, average price, long lasting

Given 57% while driving a Kia Motors Sportage (225/60 R17 H) on mostly motorways for 23,000 average miles
Came as standard fit on my Kia Sportage 1.7. They are good in the dry from new and very quiet. The tread grooves are different depth, so the tyre starts with a good profile but at 23000 km the "thin" grooves have disappeared from the front tyres and they looked like semislicks despite having in theory 4mm left. They lost grip completely in the wet and cold, gave me a good scare and were promptly replaced by Michelin Crossclimate Plus. The rear ones were still nearly new, probably to do with my car being FWD, I would say the fronts wear 5 times faster than the rears. I currently rotate, putting the Michelin at the front in winter to give me better traction and braking, and the Hankooks at the front from spring until autumn so I wear them down and replace them with another pair of 4 season tyres. Would not recommend them.

Given 71% while driving a Hyundai ix35 (225/60 R17) on a combination of roads for 35 easy going miles
The ix35 has covered 35,000 miles on this set since new and still not worn. Looking to replace as the tyres are 5 years old and starting to crack. Had better tyres in wet and dry - but never one that has lasted so long that we've had to replace due to age not wear.

Given 80% while driving a Hyundai ix35 (225/45 R17) on mostly country roads for 40,000 spirited miles
Front tyres never rotated clocked up 33000 miles on varied road surfaces and hard driving motorway. Rear tyres still going at 43000 miles. Great value for money. Nice looking tyre. I drive a Hyundai ix35. The tyres were standard factory fitted as new.

Given 61% while driving a Hyundai i30 (205/55 R16 H) on a combination of roads for 40,000 average miles
Came with my new car in 2011. They are not that bad I use them only in the season. I have got 30.000 miles out of them and they still look like they are new - zero wear!
The ride comfort is not that good, I enjoy better ride comfort with my winter michelin a4 set. Grip in wet conditions in the summer is not a problem, they handle ok on all kinds of surfaces.
Would not recommend them in the winter thou as cold conditions decrase their grip.
Overall a good tire for someone who puts a lot of miles on them and owns a winter set. I am convinced these could last me more than 50.000 decent miles but I will probably throw them away after the next season since they became too thick for me and I prefer ride comfort.

Given 91% while driving a Ford Corsair (australia) (195/65 R14 H) on a combination of roads for 48,700 average miles
An excellent all round summer touring tyre for a four cylinder FWD sedan.
The car has been driven all roads from Express ways to hard rock and muddy goat tracks in four southern Australian states.
Limited used in snow but performed quite well.
Removed with 2-3 mm tread remaining as the winter wet has arrived.
The best steel belted radial touring car tyres I have ever purchased.
