1999 camry 2.2L vibrations

[K-Ran]

Hi, The car is vibratiing in a strange manner around 2000 RPM. It does not do it when its cold but only when it gets hot. Vibration dies below 1700 RPM and above 2500 RPM. I was told by someone that my tyres were bad and need balancing but the car does it while stationary as well. I changed the alternator as well a couple of days ago (not because of vibrations.. it just stopped working ) and thought maybe it would fix it but it did not.  thanks

When was the last time that the timing belt and water pump were changed? How many kms on the odometer? When was the last engine oil and transmission fluid change and replacement of spark plugs done? 

More of a question to eliminate potential cause before considering imvestigating other expensive options of worn bearings.

thanks for the reply mate...191000 km on the odometer...the engine oil was changed 2000 km ago and transmission oil was changed 12000 km ago. ( This was when i bought the car)... dont really know about timing belt, spark plugs and water pump.... probably gonna have to check the sparkplugs next....

Probably want to inspect the engine mounts. If they are worn, they will amplify the engine harmonics directly to the chassis.
