Neil, The maximum safe pressure for every tire is printed on the sidewall. I think radials are less prone to low or high pressure wear patterns than bias tires. Generally, more pressure stiffens the entire tire so it has less side flex on corners for better handling. Too much pressure makes the ride harsh and reduces the radial tire's ability to flex into contact with the road. The best pressure also depends on the tire size vs. vehicle weight. I have also experienced huge differences in handling between different brands of tires of the same size and pressure. Some people like to run at the maximum pressure, but I think that is usually too high for best performance. And the preferred pressure for original bias tires is usually not enough for radials. My guess is 35 - 40 psi would be a good pressure range for our cars.

I just happened to increase the pressure on my Diamondback radials to 40 PSI , on the front tires; the rears are still at about 34 PSI, and noticed greatly improved handling & braking response. Has anyone run a high-air-pressure on their radial tires? Any negative results? Back-in-the-day, road testers said they applied around 36 PSI to the bias ply tires , so, maybe 40 isn't too high. What WOULD be too high?
