The vehicle manufacturer sets the inflation pressure based on a lot of different parameters - and ride quality is certainly one of them. But ALL the vehicle manufacturers work within a small range of load vs inflation pressure values - ones that are easily characterized so the tire manufacturers set up their tires for those conditions. I am of the opinion that using inflation pressures outside the vehicle manufacturer's specification has inherent risks - and ones that we just don't have a good handle on.

I'm beginning to be swayed. . . I was originally sold on pumping these things up to 51 and riding off into the sun, however, I'm having second thoughts. Given that these are "low profile" tires on a 4,000 lb luxury car, I'm hesitating to pump it up much about 40. It definitely seems like using regular compressed air is preferable to pure nitrogen, but 40 psi is quickly becoming my absolute (and admittedly somewhat arbitrary) max.
Am I just being a chicken?
