Hi, New to the board -

Wondering if you folk can help me

I have a 1996 x300 3.2 sport with stock rims, new branded tyres, which have been balanced, new rear wheel bearings and the car as just done 100K

I get a slight vibration at 50-55 mph and then a much bigger vibration at 80-90 mph. All other speeds are smooth.

I have swapped the tyres from the fornt to rears but the vibrations remain. The vibration was also there before the tyre change

Are there any problems inherent to this model? what elseshould investigate?

Thanks
