just for driving ? i just want them to wear evenly and get a full contact patch down but not so low of air they wear out faster and sway

thanks

25psi, the guys at Discount Tire ran 30psi and the center wore out in 8 months(8500 miles)

Damn, I only run 20psi in mine. Anything over that and the centers start getting thin really quick on mine.

I Run 20 Psi In My Nittos To I Guess I Will Not Be Going Lower Than That

When I got mine installed they were at 30, then I noticed the center wearing and dropped them to 25.

25 PSI on the street, and 15 PSI at the track.

18 PSI, daily driven, wearing perfectly

I usually keep between 24-26 psi in them. I've found this to be the best compromise between even wear/traction/handling. The higher the psi the better handling I got, but that compromised wear mostly and traction a bit. Lower psi made the wear better and traction slightly better but handling was too sluggish for me. I know when its getting closer to 24 psi because the handling does get a bit more sluggish.

20psi in mine

Are ya'll running these pressures on the extreme drag radials or what? Reason I'm asking is I just got them for all 4 corners of my SS. 315/35/17's on the rear and 275/40/17's up front. I immediately noticed that the front end gets very nervous and wants to wander all over the place at rough intersections or other pavement irregularities. On smooth roads all is perfect. The pressure is at 32psi in all 4 tires. This is my first time with Nitto's so I am not sure what if anything I can do to improve this condition. Thanks

I have Goodyear GS D3s up front and I run between 36-38 psi up front always.

I run the same preasure in mine on the street with no problems at all.

OK, looks like I might have made a mistake getting them on the front too but if I am reading ya'll posts right adjusting on the air pressures could improve the handling. I'll try upping the fronts to near max cold and give that a try first. Thanks for the input.

I run 35psi on the street. I have the 555RII's on the car.

What a difference a couple psi can make! Upped the fronts to 39psi and set the rears at 30psi. Major improvement to the handling especially with rough intersections. Still wants to follow the ruts a little but I didn't have to hang on with a death grip like before. With all the salt still on the roads around here it looks like the fronts are still making contact with the road across the entire footprint but the rears are lacking about a 1/2 inch on the ends so I may drop them down a couple more pounds and see what that does. Thanks again for all the input.

Now you may have to adjust the pressure depending on the weather. Just experiement and you'll find the best combo for different weather situations. I know I notice a difference once it gets warmer, particularly above 50-55 so just play around to find the best for that kind of weather.

35-38 psi on the 555's. they reccomend 40 psi i believe
