Air Pressure and Nitto Drag Radials
I run 275/40/17 nitto drag radial on 9" rims on the street everyday at about 15 psi. I was noticing that im wearing out the center 3" of tread, but the outsides of the tires still have tread. Generally this is a symptom of overinflation, Right? Am I running the tires at too low of pressure and having the opposite effect? I dont think I can go much lower without risking the tire coming off the rim in a sharp turn. Anyone else having this problem? Any suggestions? What air pressure is everyone else running on the street?
Thanks Joe50

drag radial psi.
I run the BFG drag radials on the stock 16x7 5-star wheels. I usually run the tires at around 25 psi. on the street, and they wear very evenly. I used to run them at 30psi. and the wear pattern was normal then as well. If I'm going out looking for trouble ...then I might drop them down to 15-20psi., but only for that day.

underinflated on the highway, maybe the center would bulge out and wear the center and not the edges. i dont know. i wouldnt run them that low everyday though, i would do what simistang said and run them at 25 give or take a few.

I used a set of Nitto DR for the entire race season last year. Trust me the tires hook the best @22-28 psi.
You need all the rubber touching the road for a good launch. When I tried them @12-20 psi they didnt hook nearly as well. Later,
