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.

Are these tires quiet !!!

Unfortunately we've no experience with the noise levels of the Dimax 4Season. The EU tire label in your size would be a good place to start, though that is only a measurement of external noise.

Top 3 Radar Dimax 4 Season Reviews

Given 80% while driving a Vauxhall Insignia CDTI SRI 160 (245/45 R18) on a combination of roads for 15,000 spirited miles
Have previously used a mix of UHP (michelin, goodyear, conti) , Mid range (vreds) and good reviewed budgets (Barum, Matador, Nexen etc). Picked the Radar Dimax 4s as wanted a budget all season. Have done 15000 progressive miles on them on the fronts over winter and summer and down to 3mm. I like to test tires to their limits. Obviously not as good as the UHP Suummers but these have been a great budget all season option. If I drove normally I could probably have got 20-25k out of them easily. They were great down to about 4mm, then could feel them start to give a bit however when they went it was still controlled. Were great over winter aswell. Decent in dry, wet, and snow. Wouldn't hesitate buying again if wanting a budget.

I have 33k miles on Dimax E Touring on my 2006 Honda Accord Lx 2.4L 5 speed manual and still have 30 -40% tread left. Very surprised on how long they are lasting.

Given 46% while driving a Mercedes Benz C220 cdi (205/55 R16 V) on mostly town for 13,000 average miles
Bought these tires as needed a all season tire and was on a budget and for the money they were fine however I have now switched to a mid range tire and they show the weakness of the radar tires immediately if you want a (very) cheap all season option I would recommend these but if you can spend a little more then much better options exist

Volkswagen (225/45 R17 H) on a combination of roads for 2,000 spirited miles
Still pinching myself, waiting for the day they'll not be amazing, went from premium, all be it worn, tires that were noisy, vague twitchy steering, prone to sliding and drifting in corners and needed caution when roads hit damp.... Over to Radar all seasons as had winter tires last night year and amazing in the snow, but wasn't expecting more than mediocre from these budgets.... Anything but, transformed a car I was dissapionted in and half ready to get rid of... Much quieter, more comfortable, feels secure in dry and wet with good feedback from steering, no more sliding wet or dry, I can feel where the tires are and what they are doing, you can feel them holding onto the road, car is more fun and alive to drive and yet more secure in all conditions, yes even up a very sharp turn and incline in the snow without hesitation where I thought again all seasons may hesitate compared to winters. Never considered budgets before, never heard of radar before, thought all season budgets could be the worst of everything but reluctantly took these on recommendation of the garage from customer feedback, best decision I've ever made. Just bought a second car, it will be getting a set of these ASAP.
