Hi guys,i replaced my tires on 04 330 last year with 255/55/18 on original 18 graphite wheels with 5 mm spacers,yokohama tires,geolanders,evey thing was fine untill last monthe i started to feel vibration at differnt speeds mostly 60 miles/h or faster,i did have rebalanced the tires but no change although initally there was little improvment,the funny thing is this vibration is not always there,sometimes braking the car will exaggearte the vibration.
Tires look good no visible or felt deffects.
ANY IDEAS PLEASE thanks

 

If the tires are balance, check the steering linkage, suspension and your brake component. Also, try rotating the tires (front to back) and see if the vibration is still there.

 

Need to separate the vibes during braking (rotor/pad contact) from free rotation vibration. If the free rotation vibration at speed "x" varies after application and release of brakes, then the suspect would be a loose/shifting mechanical part.

Note spacers and wheel modifications, tend to increase/enhance the vibrations (things need to be just perfect)

All wheel alignment perhaps?

 

Your spacers might be adding to the issue. Do you have concentric hub spacers?

 

hi mandyfig,,is there any special way to install theose spacers,really i donot know what kind are they but i can say it has different patern of holes some are just the hall and others are elongated ones.if you can help thanks

 

While looking for rims for my wife's new car (not a Lexus), I saw spacer rings that go between the rim center and the bearing hub to keep the rims centered. That might be something worth looking into for your spacers. JM2c

 

You might need a hubcentric spacer, type in hubcentric spacers and do a search on the web. There's a ton of them, make for every model of car.

The elongated ones are not what you want. The hubcentric is just like any spacer, slide it in, you rae good to go, but it centers itself. Less issue for balancing. Realistically, it should not affect balance a lot, but better be safe than sorry, or getting lost in your debugging of the vibration.
