not sure about your rub problem.... have you rolled your fenders? you may have to.
just my 2 cents on the tire selection.....
I had Kumho SPT,, got talked into Nitto,,, back on Kumho ASX ,,,I'll never ride on anything but Kumho,, just my preference I guess.
but I say if your spending money on the tires I would go with Kumho over Nitto,unless your getting those Nitto's free
got a friend that has the ast's , he says they have no grip if its cold, but dry and warm there good to go,, (acura integra)
on my Nx these ASX are sweet,, No ride noise and great on wet, real smooth!...
Good luck on your New tire selection.. I have a hook up at discount tire if you need..
