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.

Hello i would like to know how much kilometers i can do with lassa tyres impetus revo 195 55 R 15 85 H

Wear depends on driving style and vehicle. Between 15,000 and 25,000km should be a reasonable estimate.

What tyre pressure would you advise for the front and rear with these tyres fitted to a 1981 Triumph TR8 205/50R15 86V

The tyre pressure for the Lassa Impetus Revo is vehicle and load specific. The correct tyre pressure for your vehicle can usually be found on a sticker in the door shut of the driver's door, or in the manufacturer's handbook.

Hi I stay in Saudi Arabia, Typically very Hot Summer,sometimes 50 deg Centigrade.Please advise if I can buy New Lassa Impetus Revo tyres for this weather condition ? What is the durability of these tyres ? Can they Last for at least 45,000 miles ? Appreciate your valuable feedback.

Unfortunately I've not seen any test data for the Lassa Impetus Revo so unsure on wear potential.

Given 31% while driving a Opel Astra G (205/50 R16) on a combination of roads for 10,000 spirited miles
Only an average kind of tyre. I was left disappointed with the wet grip and the overall feedback of them. Also, cracks started to appear after just 2-3 seasons of use. To put it simply - I wish I had bought some Avon ZV7s or Uniroyal RainSport 3s at the time (but my local tyre shop kinda pushed me to get the Lassa)

Given 76% while driving a Toyota Avensis (215/55 R17 W) on a combination of roads for 1,000 spirited miles
Its early days for these tyres but they are really good for grip and quiet. I was slightly worried about buying this brand as normally when something is cheap it is not very good. I have to say very impressed, have only done 1000 miles on them so the wear rate could still let them down but they are better than the good year excellence that came off the car

Very good tyres had these for 17months and done labour 18, 000 miles on them.change them cos the left front is very wear on side walls due to I live near a lot of roundabouts lots of right turns. They are still very gripy even in wet.done these on motorways, very good in snow specially last years winter.car is usually packed with family so not a bad tyre.

Given 74% while driving a Renault Clio 1.4 (185/55 R15 V) on a combination of roads for 12,000 average miles
I bought a Clio 1.4 in April 2011 and these were fitted to the front. I have to say that they've performed fairly well for a budget brand. I didn't make a note of the tread when I bought them but they looked fairly new with lots of tread. I've covered 12,000 miles in 10 months in all conditions and all types of road. I don't recall any scary moments, but then again, I don't drive like a lunatic. I have the odd blast now and again, to the legal speed limit obviously. I'm changing them at the moment with 3+mm of tread left as they're starting to let go in the wet and are getting fairly noisy. They look good and have a sporty tread pattern. I don't really know how they performed from new and probably wouldn't specify them to be fitted as I wanted to go for a better brand this time round. I was recommended Vredestein Hi-Tracs over Toyos and are now on the front, for only £125 fitted.
