Some pros and cons about them.Super great grip,these things are hard to break loose.I'm running 15 - 16 psi also. Awesome cornering ability too.Now for the negative: They are loud!!! And i'm not super impressed on the balancing of these tires.I've Had Nitto Drag radials 555's,perelli pZero's,And michelin pilots.The michelin pilots were the smoothest tire as far as balancing and noise but didn't compare to the nt05's for grip.
