• When working with ET Drag Radials use 1 psi adjustments to see change.
• A radial will perform quicker the more air you can run.

ET DRAG MOTORCYCLE

These recommended pressures are guidelines only, actual pressures may vary. Wheelie bar settings are with the front end extended and can vary as well.

ET STREET RADIAL

On the racetrack DO NOT use starting pressures below 11 psi.
Recommend pressures for:
P295 and larger sizes: 12-16 psi
P275 and smaller sizes: 14-18 psi
On the highway we recommend running 75% -100% of maximum psi stated on the sidewall of the tire. This will vary depending on the weight of the vehicle.
