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.

Good shock absorption and low noise on rough asphalt.
Difficult to control in a crisis situations. Poor braking performance.
Turkish Petlas offers one of the cheapest products you can find online. But Imperium PT515 is NOT an affordable solution. This is like throwing money in the lake. The stopping distance on wet asphalt is a full 10 meters longer than the best tires from 80 km / h.
In the evasive maneuver tests on dry roads, the Petlas tires can’t neutralize the lateral forces but have major problems with the load shift effect, which means that the tire skids wide and becomes difficult to control. On wet roads, it moods alternately between understeer into the curve followed by an oversteer in the middle of the turn.
Budget tires often fitted on older, cheaper cars with poorer crash safety. It is a life-threatening combination. Save money on something other than the tires.

Top 3 Petlas Imperium PT515 Reviews

Given 72% while driving a Ford Transit Courier (195/60R14/ R) on for 15,000 miles
The tire was solid, there was no fault or defect. The seller sent it very quickly and I did not pay for the installation. Petlas's best tire is IMPERIUM. I used Falken before. Falken is better quality than Petlas, its wet and dry ground grip is better, but it wore out quickly. Falken is a soft tire.

Given 70% while driving a Renault (205/65 R15) on mostly town for 20,000 average miles
Good noise and shock absorption, way better than my old michelin green X. Grip is pretty good from getgo before they warm up compared to others I used, but only serviceable in rain. Fuel consumption is more compared to green x, but i exclusively drive in start stop traffic so not really noticeable in my use case.
For hard cornering its way better than green x's but thats not saying much considering those are eco hypermiling tires.
I got them for a pretty good deal, and they are available in some of the hard to find sizes, which was why I bought these.

For six years I've been using these tyres. And stil looking good ( I used it only 12,000 km's) I'm about to change them to 4 seasons tyres for my conditions. I am not an agressive driver and never had a problem with these tyres even wet.

no bad.

Given 87% while driving a Hyundai Accent (195/60 R15 V) on mostly motorways for 55 average miles
Used them for 88,000 kms and has to change them because of uneven wear on 1 tyre. Haven’t reached wear indicators yet. Handling for wet & dry in the tropics under everyday normal conditions is very good. Best economical tyres in my book. I replaced them with exactly the same tyres. Highly recommend these.

Wet performance is not very good . The tyre grips on dry ground and the braking is good, but as the rubber ages, these properties also disappear .
