Two scoring systems, side by side
Owner scores come from reviews found online; road-test scores come from instrumented tests. Where they disagree, it is usually a discipline owners rarely push to the limit.
How scores work
- Relative score
- 0–100. Blends road tests (60%) and owner reviews (40%) category by category, the same way on every TireWheelGuide page. With only one of the two, the missing half is estimated from it, so the score stays closer to average. It needs at least one road test or five owner reviews.
- Road tests
- 0–100 per score, from published tests, newer tests counting more. Each result is compared with every other tire in the same test, so a win against a strong field counts for more. The average tested tire gets 70, the best 100; with only one or two tests a tire stays nearer 70. The discipline rows show % of the best tire in that test.
- Owner reviews
- 0–100 from the owner reviews we found online, adjusted for how generously each site rates and scaled like the road tests: the average tested tire gets 70. With only a few reviews a tire stays near the average.
By owner reviews
61/100From 80 owner reviews analysed, scaled like the road tests: the average tested tire gets 70.
By road tests
65/100Scaled across every tested tire: the average gets 70, the best 100.

The BFGoodrich G-Force Rival S 1.5 is widely regarded as a premier 200-treadwear tire specifically engineered for autocross and time-attack competition. While it offers exceptional dry grip, rapid warm-up times, and impressive longevity compared to its direct rivals, it is less suited for sustained road course endurance racing where it can become 'greasy' under prolonged heat.
Pros
- Exceptional dry traction and lateral grip
- Rapid warm-up, making it ideal for short-duration autocross
- Superior tread life and durability compared to other 200TW competitors
- Predictable handling and high driver feedback at the limit
- Available in a wide range of sizes, including large fitments for muscle cars
Cons
- Performance degrades significantly in wet or cold conditions
- Tendency to overheat and lose grip ('grease up') during long track sessions
- Increased road noise and tendency to tramline on public roads
- Requires precise tire pressure management to maintain peak performance
Worth knowing
- Users with heavy vehicles (e.g., Camaro, Mustang, Viper) report the tire handles weight well and provides consistent performance for time-attack sprints.
- Miata owners frequently note that the tire provides a transformative increase in grip, though it requires careful heat management on lighter chassis.
- Staggered fitments (e.g., 225/245) are commonly used to balance handling characteristics on rear-wheel-drive platforms.
