my car has about 20k and i havent done the tire rotation yet...

should i do it? cuz in the manual i shouldve done it at 7k lol

or is this unnecessary but its recommended??

can this be done at home with jack stands? just lift and switch like u change ur flat tires?

if I do it mine is pure 02 sedan ex 4 stock tires, should i follow directional? or non-directional instruction???
