for those who have the Cooper Zeon LTZ's and have experimented with different PSI's levels on the 19" rims. What has been the PSI that worked best on Highway/Street and for off-road?
Thanks,
Dave

For street theses are factory size pressures are listed on door frame. For offroad depends on terrain and surface.

You are stating the obvious. I know where to get the tire pressure for my cars. I was asking those with the Cooper Zeon LTZ's tires.

And stock tire size difference is?

Tire brand and model shouldn't make a difference if it's the stock size on the 19's. Just because they're Coopers doesn't mean you need to run a different pressure than whats listed on the door. The Cooper has the same load rating as the factory tire that came on the vehicle. You can experiment with different pressures especially off road. I'm running the GoodYear DuraTrac tires in the stock 19" size at the recommended pressures and they have been fine. If the tire is oversized you will need to adjust the pressures.
