My tramlining's gone, but.....

[RUSSELLM]

I don't know why.

I got it back from it's MOT on Friday. It's had the Toyos removed off the front & swapped for Continental Sports with a straight tread pattern.

It failed the MOT on "Steering Wheel retaining device insecure". Which I presume, is one of the allen key bolts that had started to come out of the centre of the steering wheel.

I'm waiting for an email back, to determin how "loose" my steering was.

But my money would be on the tyres curing it.

Puzzled but happy

Could well be the profile of the shoulder of the tyre. I really wouldn't know whether it would be better to have a rounder shoulder or not, but I'm willing to bet than one shape is more adverse to following the lorry tracks than the other.

I find new tyres, regardless of type, help.

With my technical abilities, I really shouldn't be driving this car

Having just swapped my wheels over, I'm a little suprised at how sensitive the car is to tyre size. Same diameter wheel, with the same manufacturer and type of tyre - very different feel and sound due to width alone.

It doesn't surprise me that the tramlining on yours has gone with a different tyre brand...

I go past a couple of scrap yards on the way home from work, and you can see the grooves in the road. The steering wheel used to physically move as the car tried to throw itself in to the furrows. Obviously at high speed on the motorway, the car used to feel dangerous. It's like a different car now on the way home. The way it should be.

I've just put a set of SP12s on mine, same fronts but a wider 265 rear. The difference is very marked even though I am no driving genius, and I have the same brand/type of tyre on (T1Rs).

The stability through the bends is markedly better, the comfort over bumps is noticable - it just seems a sharper tool now...

This will largely be due to the fact that you now have wheels that are the correct widths and offsets. The fronts are the ones changed most markedly over the spiders.
You will have noticed that the front tyres are not stretched over the rims anymore and that the sidewalls are more 'upright'.

When I changed to sp12's I noticed the same improvements you have.
