i was wondering if its ok to do a side to side tire rotation, im currently running kumho ecsta asx. also does any one on here have the right alignment specs so when i take it to get it aligned they do screw it up. thanks for your time

 

my fronts/rears are different size rims and my tires are directional also so i don't do rotations.

 

a side to side rotation really won't help with wear unless you have them dismounted, flipped and mounted so that the side facing out is now in.
(this only works on regular and directional tires, not asymetric)

btw this is what i do, and you limit the amount of wear on either the inner or outer edge, depending on the allignment... down side is that you have to pay for the mount and dismounts

 

25 dollar per tire to mount and balance, not sure if that's even worth it
