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 Kumho V70a Reviews

Given 76% while driving a Fiat 500 Abarth (205/40 R17) on a combination of roads for 3,000 spirited miles
Fitted a set of soft compound v70a's and they have performed really well during motorkhana events. Plenty of grip and stiff side walls for stability. Haven't tried them on track in the wet but have been using them as a daily and have had no issues on rainy days. My only concern would be how quick they wear but that is to be expected for soft compounds. Also cheaper than most of it's contenders.

Given 96% while driving a SEAT Leon Cupra Tdi (215/45 R17 W) on a combination of roads for 5,890 average miles
the first time after a long time. I was very pleased. strongly suggesting friends who are thinking. wet and dry performance is amazingly good. I took it to the street and the runway. and I use it from both sides. I will definitely take it again. road holding and reactions after tire heating are absolutely necessary.

I used the product in MiTo. the dry ground is incredibly good. It is also possible to use it in normal city. it feels safe in the rainy weather. I did not expect so good. I will definitely buy it again. I wish you a good day.

Hello. I would like to comment between the two as someone who used toyo earlier. Toyo is also a very good quality tire. I was very pleased. gives incredibly beautiful results on dry ground. I also used the toyo tire MiTo. I can say that for kumho. medium point tjet model. and I chose this tire to use it daily. The result is excellent. The tire is incredibly grasping the way of heat. very good on wet ground. I am very surprised by this performance. Suggest to friends who think.

Given 60% while driving a Honda Civic Type R (225/45 R17) on track for 600 spirited miles
Good once you have heat in them, you can really nail it in the dry (K60) med compound. I bought some old tires (5 years but still had preserver on) and I think they're probably better younger. I had no grip in the wet until they were warm (on the rear they were useless but ok on the front/FF car).
There's not as much tread as r888 or 595 federals which means driving home on illegal tires if you don't watch the wear.
They were so stiff to get on, now my mate won't change my tires any more!! The sidewalls are mega strong.
Easy to spin in the dry if you have them on the rear and they are cold also, beware.

Great dry grip/track tires. They do wear very quick though, I killed a brand new set in my M3 track car in a day. Great fun but very expensive day.

Given 86% while driving a BMW M3 CSL (265/35 R18) on track for 7,000 spirited miles
These are the best tires I've ever tried on my M3 CSL.

I used the medium compound and the level of grip is just amazing as they warm up pretty quickly unlike the Michelin cup tires which are good a hot day otherwise no grip as they take much longer to get them warmed up and if the track temperature is below 10degree then you'll end up spinning!

I've never felt safe and confident driving hard as I did with these tires. 5*

I've done 4 – 5 full day track days with these tires on the race track and I was all over the big boys! Plus 7000 miles on the road.

Excellent dry (cold or warm) grip and very good on wet (tire pressure has to be correct).

I recommend these tires for both track and road use as they are very safe.

Given 87% while driving a BMW E36 328i saloon (225/45 R17) on mostly country roads for 2,000 spirited miles
I run these on my track prepared E36 328iSE saloon, previously I ran Falkens, Michelins and then I invested in TOYO proxy's...all great tires the latter being incredible. BUT, by chance i ended up with a set of KUMHO V700 V70a Hard compound tires.

First experience of driving with them was on the dampest wettest day ever, satnding water rolling across road, so i was a tad apprehensive about what to expect as KUMHO have always been a ''cheap'' tire in the back of my mind.

Once I broke the initial membrane down and they started to heat up, my loaded with me and 2 passengers. I was starting to accelerate and brake at a reasonable pace, till I realised that I was driving quicker across this particular length of country road in ridiculous conditions on the upper side of three digits. These tires are incredible, the way they push the water to allow traction is incredible. High speed stability (combination of tires and suspension set up) is second to none. At the other side of 140 is equal to that at 50. I can't rate this tire enough...! On a RWD BMW this tire feels so at home.

In the dry...NOTHING COMPARES as a road tire...I'll eat my hat if you can prove a tire equal or better!

Wear isn't too bad on the hard compound, Im sure with a dose of spiritedness and easy motorway driving one can achieve 5000miles easily. I would recommend these tires over Proxys, Yoko's (which I had on my MR2) and the brands above, just for price and performance you'd be insane not to give them a go...I will the moment I can afford 650 for a set.

Given 87% while driving a SEAT Ibiza Cupra TDi (205/40 R17 W) on track for 120 spirited miles
Bought for the track but will be be used to drive to the track as well ( apart from the ring where i'll swop wheels when i get there) Have done about 60 laps of oulton park in cold and wet conditions and although conditions were far from ideal they were slightly better than street tires.

However ever once a dry line showed up (75%of track) the difference between the Kumho and a street tire was like night and day!

This is my first venture into track tires so cant compare them with other track tires.

Given 77% while driving a Subaru Impreza (225/45 R17 W) on a combination of roads for 90,000 spirited miles
These tires come in either a hard or medium compound (also soft or super soft for different tire sizes)and really are excellent track day tires with massive reserves of grip. Found them best running at 40psi front and 35psi back on track. Lasted a full day on the track and should be good for another 2 sessions, Tried them in the wet on ordinary roads and was amazed by the grip, they have a tread wear rate of 50 for the hard compound, as compared to about 240 for normal tires. Have run R888 but the kumho are better tires, especially when really warmed up.
