Have you tried putting your old wheels on again to see if the problem is still there?

i would dismount the front tires and check the rims by themselves. Afterall,wheels from China can be of good quality or very poor quality. If the rim itself needs more then .25 ounce, ask for a replacement, if not remount the tires and rebalance. If you still have the problem, it very well could be the bushings. As for why the vibration "surfaced" after the tire upgrade, it's because they are wider and of lower profile, and that causes a higher load on an already "sub-par" bushing.

Hope this helps.

do you notice the vibration more when you hit the brakes?

my old whels are gone... sold em on...

if my car vibrates when i touch the brakes. by that i mean its more notisable, what does that mean?

Once again, I have to suggest checking the thrust arm bushings and inspecting the rotors to see if they're warped.

The vibration + getting worse when hitting the brakes = those two components.

Best, whit

ok
so does this mean i may have to replace the brushings only? (costs around $60AUD i think) what do i do about the rotors if there fudged as well? if i have to replace them how much am i looking at?(plz include currency)
