D2 Tramlining

The old girl has just passed her MOT with a few advisories but none related to tyres, suspension or bushes - however she struggles with the tramlines on the A14 to the point where it gets quite scary.
Any ideas where or what I should look at ?
Thanks

I've found most A and M roads will give the tram-lining effect if your in the near side lane, but please don't be scared.
Just do what I do take the outer lane most times.

I get that in my motorhome and it scares the bejesus outta me! Feels like a rear tyre blow out sometimes.
Unfortunately, due to low power to weight ratios I have to spend nearly all my time in the lorry lane.

What size wheels have you got? My TD5 did the same until I replaced my 18's for 16's. I also had different make tyres on all 4 corners as well (previous owner) which I'm sure didn't help.

I've found it has nothing to do with with wheel size I have had the same experience with wheels 13inch to 20 inch it depends on if you're tyres will fit near the tracks that HGVs have left.
Try driving a car with wider rear tyres to get the greater experience of driving in the near side lane, great fun at speed.
No probs in the outer lanes, try it

Every body should be in the left 'lorry' lane unless overtaking lol
