I just replaced the original Yokohama tires on my 2010, gen 3 model 2 with Goodyear fuel max tires. (both at 40 psi) It made for a huge reduction in ride harshness and interior road noise. Also lowered mpg from 53 to 51, but may be a worthwhile trade. Others tell me the mpg may recover a bit as the new tires wear/ break in.
