Ok, might be getting somewhere now.
Took it to local tyre place to get all four wheels balanced as I wanted to try and rule things out.
It turns out that the n/s front buckled wheel which I took for repair the other day is still slightly buckled
and the Track Rod End need correcting on that side.
Also when balancing the back wheels he had to use a lot of weight due to the fact that the tyre had worn so much uneven.
Basically all my four tyres need replacing, so will get the Track Rod End done first and get a new set of tyres and balanced again and that should be it.
Just to put my mind at rest, I got one of my friends who deals in cars to have a look and drive to see if he could feel anything wrong, but he couldn't other than needing four new tyres and that he thinks that will help with the "rough ride feeling" combined with the fact it is the first time I have used/driven a car with 45 profile tyres on.
