hi all

Alright, at first I just thought that my tires needed air, but even since I put air in them this problem has gotten worse.
You know how it feels when you go down a bumpy road? cars tend to follow the road... in a bad way? Like when you come over the crown of the road, it redirects? Like the wobble back and fourth with bumps?

im running 225/40/18
3 with 6mm+ tread and one with less then 3mm which is on the front passenger side
wheels are rx450h wheels with et35
things i had changed in the last 6 months are
inner and outter tie rods
upper balljoints
lower balljoints
lower control arm bushes
caster bushes
and Alignment done by wheels in motion

it passed its mot just last week

thanks in advance guys

you could try swapping the fronts with the rears wouldnt hurt to see if theres any difference if you think its tyre related, you may of lost a ballencing weight off a wheel? or it could be a sticky calliper?

Sounds like you're describing tramlining. What brand are the tyres?

hi mate

i am thinking of changing the fronts to 215/40/18 anyway
on that note can you do that on a lexus? i know you could change tyre sizes on the bmws
im thinking front 215/40/18
and 225/40/18 rear would that make any difference to handling? i mean in a bad way?

thanks again mate
