Hello all just wondering how much psi you guys run on the niito dr's. i noticed mine are starting to wear on the outside. Thanks...

Outside usually means you are running the pressure too low. Ideal for a drag radial is typically in the 25-30 psi range due to the stiffer sidewall as compared to a racing slick. Anything less forces the contact patch to cup (concave) so the edge of the tire is forced to support more weight than designed. If you run them on the street mostly, just go with the minimum suggested tire pressure as marked on the tire and you should be fine. :cool:

The way I've always set the pressure on my 555r DR's is to do a burnout and check the black mark - if darker on the outside edges, add air - darker in the middle, take a little air out. Usually, 25-26 psi gave me the best mark / traction overall. The NT05r's require a little less pressure to get an even mark.
