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 Kleber Viaxer Reviews

Given 73% while driving a Fiat Panda (155/80 R13) on mostly town for 8,000 miles
On uneven surfaces, the tire is a bit noisy, but on dry asphalt and at temperatures above 10°C, it performs very well on a Panda 169 with a nearly 1300cc engine. We're talking about a tire size used on countless car models: 155/80 R13. Even at temperatures just below freezing, they perform well and are very durable despite being designed for summer use. The tires were mounted in 2022 and have covered around 10,000 km with moderate use. Wear is less than a third of their potential mileage, so I estimate they can easily last over 30,000 km. Overall, a good rating.

Given 91% while driving a Hyundai Accent (225/45 R17) on mostly country roads for 9,500 average miles
I have these tires for 16000km. They are very good.The only question is about their wear.

Given 77% while driving a Ford KA 1.3 (165/65 R13) on mostly country roads for 8,000 easy going miles
bought for ?33 each
may fitters say its a buget brand but they wear and handle like a mid range
after 8-9 k miles they are less than half worn
owned by michelin but far better durability than kormoran and tigar

Given 76% while driving a Ford KA 1.3 (225/45 R17) on mostly country roads for 8,000 easy going miles
Had these fitted on a Ford KA for 9 months now (KAs are originally supplied with these when new) and cost ?33 each from an independant fitters. Must have done around 8-9k miles on them and they are less than half worn. Cant say much about the cornering etc as my partner is a very careful driver. I have had no problems with wet or dry grip when driving myself on the odd trip. Kleber are owned by Michelin. At the far budget end of the market you have Kormoran and Tigar which are Michelin owned. Some fitters would say Kleber are a budget aswell but several on-line tire companies are advertising these as mid range and I would certanly agree that this is a mid range performing tire at a budget price.
