I would suggest that you check the wheel bearings for condition and adjustment
have the cv joints checked for that drive axle
check all suspension ball joints and steering ball joints on that side

Check for a worn universal joint on the drive shaft going to the rear wheels.

Check your transmission fluid level. (Low level can cause vibration on acceleration.)

Check to see if your transmission filter needs changing.

Does it only vibrate under heavy acceleration?

idle control valve if it is a TR/TS magna

Check the mount,s and drive shaft first.

Mitsubishi's have always had problems with their throttle bodys carboning up, Magnas and Pajeros especially. Clean the throttle body with a can of carburettor cleaner, don't forget to open the butterfly and get right in behind it. Also check your ignition leads with a multimeter, any more resistance than 4000 ohms per foot of lead length, replace the lead. The misfiring may also have now damaged your oxygen sensor, check this with an analog multimeter, the O2 sensor output should vary between 0 and 1 volt as the needle moves between these readings (to vary the mixture) if not then replace the O2 sensor also. This problem is not related to your tyres.

Welcome to fixya the best thing to do is check the rims for imperfections and slight bents that causes the vibrations at that speed go to www.collisionrepairadvice.com to get a wheel repair company to look at.

Check your engine and transmission mounts .

you open up the hood of the car or as it is called bonnet and you go to the back of the headlight there shold be screws there and you open the and simply pull out the cover and pull out the bulb

I'm just guessing but i would say you have a bad engine mount.
