We see this so much, both on here and in everyday practice. Sometimes,
it's something else; but so often it is tires out-of-round. Ie., you can
run a metal rod thru the center of a 4-sided(6-sided if you count all
surfaces?)box, mount it on a tire-balance machine, and balance it perfectly,
yet it will not ride smooth if mounted as a tire! And, yes, it can happen
with ANY brand. HTH, s
If it's front end, adding a bit of tow-in might reveal some wear not
spotted by the person who did the alignment. If you do this, rotate
tires frequently to equalize the added wear.
If it's tires, shoot for a replacement by the dealer. If that can't be
managed ask if they do 'tire matching' This is an older process --
involves shaving some rubber from the shoulders of each tire in spots
where the carcass is stiffer; then, rebalance. Might smooth things out.
