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.

Low purchase price.
Very low grip in all tests, extremely long dry and wet braking, long snow braking with poor traction, high levels of noise, high rolling resistance.
The Star Performer SPTS AS might be a cheap tyre to purchase, but it has very low levels of grip in all conditions and cannot be recommended for any type of driving.

Very cheap to buy, but the loss of performance is not worth the risk.

Latest Star Performer SPTS AS Reviews

Given 96% while driving a Mercedes Benz S320 (225/45 R17) on a combination of roads for 1,000 average miles
With any tyre driven in wet conditions its down to the driver to use common sense. That said these budget tyres inspired as much if not more confidence than the Continental sports contact 2s I had on the car prior to these. No nasty shocks for me they grip extremely well wet or dry. They are Winter AS marked and I have noted sold as Winter and also All Season tyres. Not tested in the Snow as yet but looking at the aggressive tread pattern I feel they will be up to the task should conditions dictate. I often wonder who's really behind the negative reviews you see on budget tyres vs premium big name brands. Real world I find little if anything between them on the road.
