We’ve had a lot of requests for Vitour P1 autocross comparisons, so here’s a standout from the archives—an early 2024 test against the Yokohama A052. Conditions were cold (48–51°F), the surface was asphalt, and the course was tight and technical—classic autocross.
The Setup
- Car: Stock 2023 Corvette Stingray
- Event: IndySCCA / Lincoln Tech (April 21, 2024)
- Surface: Asphalt, bumpy and not ideal
- Tires Tested: Yokohama A052 (295/30/18 front, 315/30/18 rear) and Vitour P1 (same sizes, then tested with 345/25/19 rear)
- Format: Two drivers, alternating sets, with data and video review
Key Takeaways
- Cold-Weather Grip: The P1 worked surprisingly well right out of the gate—even in sub-50°F conditions. First-run performance matched the A052, which was unexpected.
- Consistency: The P1 maintained pace across all runs without falloff. The A052 showed more degradation, both in grip and wear.
- Treadlife: Wear on the A052 was visibly worse compared to the P1.
- Grip Advantage: The 345/25/19 rear P1, even on a narrower wheel, delivered faster lap times and more grip than the 315/30/18 A052 setup.
- Real-World Results: Both test drivers placed 3rd and 4th in overall PAX for the day—on P1s. The top PAX finisher also ran the P1 in STX on a 245/17 setup.
