I recently purchased my 2016 Disco 4 Landmark and I have a question about the suspension.
The car has done 19,000 miles, when driving over uneven road surfaces (manhole covers and patched up roads, the 'shock' doesn't appear to be suppressed by the shock absorbers.
I mean the 'shock' travels up through the steering column, feels like the wheels are 'tramping'
Is this normal for the Disco 4?
 
Shock absorbers is really a poor name for the device. More correctly they're "Bounce Dampers".
The usual method of deciding whether a damper is functioning or not is to bounce each corner of the vehicle in turn. The vehicle should stop bouncing almost immediately after you stop pushing down. If the vehicle continues to bounce after you cease pushing down then the damper is faulty.
If a visual inspection shows any trace of weeping of oil from inside them then they should be replaced immediately.

Yeah, I am leaning towards the low profile tyres causing this, I will check the pressures..
 
Problem is low profile tyres need quite high pressures to keep them sitting square on the road.
Ive never driven a car with low pofile wheel/tyres thats comfy
My wifes audi is the same and she rekcons its fine, I think its like driving a go-kart, crash banh wallop!
 
Well this car is a Land Rover 'Approved' vehicle, I collected it from Matford Land Rover a few days ago and it was given a 105 point check..
I asked a service manager this morning if the 105 point check included tyre pressures, he said 'Yes it Does'.
I had to deflate my front tyres by 11 psi on one side and 12 psi on the other.
I also deflated both rear tyres by 6 psi.
This gives me 34 psi on the front and 37 psi on the rear.
 
From what I can find out, it looks like you now have the recommended pressures in your tyres for a light load of up to 4 persons.

There should be a small plate attached to the driver's door doorframe with such information.

At least you won't have to replace the dampers ... this year.

Yes I have, I found that info on the inside of the drivers door.
I would think that the same car fitted with the 235/70R17 111H wheels and tyres would have a much softer ride than these low profiles..
Thanks for confirming by the way.
Incidentally the image of the inside of the door could have been taken from my car as it is the same colour - Zanzibar Gold..
 
As @lynall has already remarked low profile tyres can give a harsher ride.
On my Disco 2 I run a set of cold weather tyres on 16" rims during the winter and normal tyres on 18" rims during the summer. Even though the tyres on the 18 inch rims aren't what you could call low profile by any means, the difference in the ride harshness is quite remarkable.
