Previous BFGoodrich Tyres Max Performance Summer

The BFGoodrich's g-Force Phenom T/A is an ultra high performance summer tyre with strong wet braking results. Internal tests show better wet braking distances than rivals including the Yokohama ADVAN Apex V601, Falken Azenis FK 510, Firestone Firehawk Indy 500, and Hankook Ventus V12 EV02 in size 245/40ZR18. The tyre uses a dual-zone tread pattern splitting wet and dry performance zones, with stiff sidewalls and shallow shoulder blocks designed to improve feedback and cornering stability.

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.

A lively, responsive tyre with good noise control and composed street manners, the Phenom T/A feels quick but struggles to deliver matching grip, especially as heat builds on track. It’s enjoyable to drive but lacks the standout performance needed to compete with the segment’s best, making it a solid yet unremarkable option in a competitive field.

Questions and Answers for the BFGoodrich g Force Phenom TA

How noisy are these tires compared to Bridgestone Turanza T005a?

No one has tested the Phenom yet, however it probably safe to assume that the Phenom being a performance bias tyre will have less focus on noise and comfort than a tyre like the T005 which is a premium touring product.

Surprisingly comfortable for a sport tyre. handling undoubtedly good both on dry and wet surface. there is noise but still on tolerable level and much better than my previous sport tyre (Direzza DZ102). Definitely will buy again

Swapped to these tyres after the original PS4 from the car tore a huge whole from cracking. Knew about these tyres about the same time so decided to go with them as they were also a cheaper option in Malaysia.

Comparing these Phenoms with the PS4, I personally feel that they are very similar to the PS4 in terms of grip. The phenoms seem to be grippier than the PS4 in dry while loses slightly in the wet. They are also as noisy as the PS4 but thats not important.

treadwear is 380 and lasted me about 50,000km with some fun in the wet. Overall very satisfied with these tyres priced at about RM500 per piece. Best bang for buck in my book as of now.
