Never saw anyone running 16" DR's. I am not sure how they will work because of the slightly shorter sidewalls, but, I suspect air pressure will not be particularly sensitive due to that. I know that the 60 series in the 15" seem to bite much better than the 50's, but who knows with these. Here is what Mickey says:
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.
