All DP wheels must have the car number stamped in the rim center section prior to having a tire mounted
Guideline for correct use of Pirelli Grand-Am DP tires:
- To optimize the performance of Pirelli Daytona Prototype slick tires it is strongly recommended to NEVER set cold pressures lower than 20 psi and to NEVER set hot pressure lower than 30psi.
- Maximum Hot Temperature should be around 220F.
- Optimum working temperature spread is about 50F between inner and outer shoulders.
- Maximum Camber permitted is 3.5°
| Description | Tread | Position | Minimum Cold PSI | Minimum Hot PSI |
| 325/650-18 | Slick | FRT | 20 | 30 |
| 325/705-18 | Slick | RR | 20 | 30 |
| 325/650-18 | Rain | FRT | 25 | 32 |
| 325/705-18 | Rain | RR | 25 | 32 |
Guideline for correct use of Pirelli Grand-Am GT tires on a REAR Engine car:
- To better optimize the performance of Pirelli GT slick tires fitted on a rear engine car, it is strongly recommended to NEVER set cold pressures lower than 28psi front and 30psi rear and to NEVER set hot pressure lower than 38psi front & 40psi rear.
- Maximum Hot Temperature should be around 220F.
- Optimum working temperature spread is about 50F between inner and outer shoulders.
- Maximum Camber permitted is Front 3.5°; Rear 3°
| Tread | Position | Minimum Cold PSI | Minimum Hot PSI |
| Slick | FRT | 28 | 38 |
| Slick | RR | 30 | 40 |
| Rain | FRT | 30 | 40 |
| Rain | RR | 32 | 42 |
Guideline for correct use of Pirelli Grand-Am GT tires on a FRONT Engine car:
- To optimize the performance of Pirelli GT slick tires fitted on a front engine car, it is strongly recommended to NEVER set cold pressures lower than 30psi front and 28psi rear and to NEVER set hot pressure lower than 40psi front & 38psi rear.
- Maximum Hot Temperature should be around 220F.
- Optimum working temperature spread is about 50F between inner and outer shoulders.
- Maximum Camber admitted is Front 3.5°; Rear 3°

General recommendation
- Pirelli strongly recommend the use of metal valves;
- Pirelli strongly recommend the use of valve caps even for short runs;
- Pirelli welcomes the use of any kind of pressure monitoring system. A preliminary fitting test should be carried out in cooperation with Pirelli Tire Technicians;
- All rims must have, if any, pressure sensors fitted by the Team prior to having any tire mounted.
STRICT COMPLIANCE WITH PIRELLI RECOMMENDATIONS WILL GIVE ALL TEAMS THE POSSIBILITY TO OPTIMIZE THE USE OF OUR TIRES.
