Default Tire Pressure For Dunlop Direzza Sport Z1

What is the best tire pressure to use on these tires?? They are 235/45/17 and the temps out here are 73 at night and 95 day. It say that maximum is 51 but have no clue what i should have them at. Thank you.

Maybe 33 front, 31 rear would be a good starting point? I don't know what the factory recommended pressure is, though, for your '07.

I've found that 45f 42r is ideal. But I have a much heavier, RWD car. The biggest issue I've had to overcome is the tire heeling over and riding the sidewall when it's not inflated enough, but that's because my car weighs about 3700 lb with me in it. Your mileage may vary.

For the street?....I'm not sure.

I run 43F/41R for autox, about the same outside temp as you. Same size.
