What's the ideal tire pressure for the street?

I did a search but only found a few posts regarding tire pressure when at the track. I'm not going to the track I just want to minimize wheel hop for decent acceleration on the street. I'm guessing about 25 psi for the rear. What should the front be?

And it is also specified on the tire itself......... I'd say 35psi max......... But it also depends on what tire you have....

You should run close to 32 psi on the street, just as Mazda recommends. If drag-strip style launching on the street is that important to you, you have to learn to launch the car better....

Driving around with low pressures on the street will result in poor handling, reduced load capacity (ie, increased chances of tire blow-out), and shorter tire life.

I run between 32-35 psi and find that works well. Low tire pressure is NOT a solution to a harsh ride, just thought I'd throw that in there .

Your question is too open-ended. The ideal pressure will vary, based on at least these factors: tire, alignment, temperature, road surface, etc.

If you're trying to dial in a setup for a particular piece of road, start at stock pressures, experiment going up and down, and log your results.

Red face I'm an idiot, I got my answer!

I suffered from brain lock temporarily and forgot about the specs in the door jam. The tires said 44 psi max and I knew that was too high. I've run them at 32 psi and that seems to work well. Thanks for the responses though.

Just thought I'd add a little comment regarding stupid people. There is a local shop here in Statesboro that thinks the pressure in a tire should be whatever the tire says, minus five pounds. The owner has been doing it this way for many years now. A friend of mine that works there recently discovered the owners ignorance and tried to correct the error only to be ignored. Just makes me laugh. Some people think they are so smart.
