1. Tire Break-In
R7 (Roadrace)
- Limit session to 10–15 minutes.
- Increase speed gradually; last lap at maximum pace.
- Avoid sliding, wheelspin, or late braking.
- Use 3–5 psi higher than normal.
- Take 4–7 laps, each 7–10 seconds faster than the previous.
- Allow tires to cool naturally afterward.
A7 (Autocross)
- Perform a light scuff-in (drive slowly around site).
- Remove tread “shine” before first timed run.
- Optionally use +3–5 psi for scuffing; reset before run.
- Expect consistency to improve over first few runs.
Cure Time (Both Models)
- Let tires sit at least 24 hours before next use.
- Ideal cure: 1 week.
- Plan for a second wheel set to manage rotation and rest periods.
2. Operating Temperatures
- R7: 180–200°F (pit lane temps).
- A7: 110–140°F.
- Measure temps with needle probe, not IR gun.
3. Chassis Setup
- Aim for ~3° negative camber.
- Reduce by 0.5° for longer wear.
- Less than 2.5° negative increases outer wear.
- Stiffer springs/shocks improve performance.
4. Pressure Guidelines
- Minimum cold pressure: 26 psi.
- Do not lower pressure to fix initial traction “feel.”
- Never drop hot pressure back to cold values.
- +0.7 psi per 10°F air temp rise.
- Keep tires shaded when idle.
- Nitrogen: Start 2–3 psi higher than compressed air; offers more stability.
5. Track-Type Adjustments
- High-banked/fast tracks: +5 psi (cold & hot) on loaded side; camber ≤ –2°.
- Autocross: Start within 1–2 psi of hot target; reset to target between runs.
6. Vehicle Configuration Adjustments
Front-Wheel Drive (FWD)
- Front tires may need 48–52 psi hot.
- Maintain large front–rear pressure differential.
Rear Engine
- Match or exceed OEM tire diameter.
- Use +2–3 psi rear.
Aero Package
- Raise cold pressures to handle downforce.
Independent Rear Suspension (IRS)
- Can safely run lower pressures if geometry and roll control are good.
- Minimum cold pressure = total vehicle weight ÷ 100.
- Example: 2750 lbs → 27.5 psi minimum.
- Extreme care: internal tire damage may not be visible.
7. Maintenance & Handling
- Do not shave Hoosier race tires.
- Avoid aggressive braking until familiar; ABS recommended.
- Check for punctures after off-track events.
- Flip tires on wheels to balance wear when needed.
8. Wheel Sizing
- Ideal rim width = tread width ± 0.5 in.
- Do not mount outside recommended range.
9. Driving Style
- Use smooth inputs for best grip and longevity.
- Avoid “tossing” the car.
- Use moderate brake pads to avoid flat-spotting.
10. Rain Tires
- Use dedicated wet tires; dry tires perform poorly in rain.
- For wet tires, +2–4 psi cold vs dry setup.
11. Service Life
- Use new tires within 2 years of purchase.
- Scuffed tires age faster.
- Store away from sunlight, heat, and chemicals.
12. Mounting Orientation
- With arrows: Mount per arrow direction.
- Without arrows:
- Circle track: serial code faces infield.
- Road race: serial code faces vehicle center.
- After wear, may reverse mount to balance wear.
13. Safety & Legal
- Race tires not for highway use.
- No warranty—sold as is.
- Misuse can cause serious injury or death.
End Goal:
Follow all phases precisely to maximize tire life, consistency, and performance.
