The car was on Goodyear GSD3s on the front and GSD2s on the rear, fronts had worn due to the tracking (I'll save the road tax pothole rant for later).

So like a good boy got the rears put on the front and the new GSD3s on the rear + the tracking done.

Now the car feels like it's running in a constant lorry track rutt, I'm not sure if I'm used to the car being sloppy and finally it's been tightened up?

Car's not lowered, has an RARB but that's been on for an age.

The guy who did the tracking said it was toeing out and now it's toeing in - whatever that means.

Should I get it checked out or is it all in my mind?

As it is now Toe-ing in (so your front wheels both point ever so slightly inwards) it will make it more stable in a straight line, it will also turn in a bit smoother (should feel a little bit sharper on corner exit though)*. I'm guessing the reason it feels like it is following the 'lorry ruts' is because it is tracking perfectly straight now, i guess you just got used to it being a bit sloppy and off ever so slightly.

*I am going by the setup adjustments we use in model car racing, they should apply to real cars aswell as it is exactly the same principle, just scaled up.

It's called Tram Linning,, It's generally worse with fatter rubber & varies greatly between Tyre Manufacturers..

You also find it worsens when you put your rear tyres on the front, as they wear differently (No Steering), Once put on the front, They adopt the same behaviour as if they were on the rear, Due to the worn in flatter profile..

Mine felt sloppy when it was toeing in, so now had it adjusted to toe out by half a degree either side.

As i understand it, rear wheel drive cars are meant to be set up as straight as poss, and front wheel drive cars should be set up with a slight toe out, because when the power is unleashed, the bushes etc deflect slightly, meaning the wheels go near as dammit straight.

I've had my rear tyres moved to the front. They are different makes. New Toyos on the back.

The trackings been "done" after the tyre change but the car still pulls to the left quite badly.

Do I get the tracking done again or is there something else I should be looking at?

But isn't this what you are meant to do? Always put new on the rear I thought.

However I'm gonna swap them tomorrow, gotta be better than this.

Putting the new ones on the rear is just to be extra safe. Eg. its better to have understeer (too much grip on rear) than oversteer (too much grip on front).

If it was me, and my fronts were worn, i would just replace them and keep the new ones on the front.

Although I do swap my fronts and rears about 4 times a year to even out wear, then replace all 4 at once. That way you keep the make an tread pattern the same. I think i have OCD for things like that. Like if i have my drivers and passengers window open, they need to be open the same amount :P

Furbys allways pull to the left, just depends what kind of road your on as to how bad it is. It will still do it on flat motorways but will only drift slightly. If its really bad then yes by all means, take it back and get them to check it again. If you didn't notice it before, your tracking was probably out enough to make it pull to the right slightly, causing it to go straight. lol

I think its somthing to do with the left drive shaft being longer than the right one, meaning slightly more torque going to the right wheel. Ive also noticed, the right wheel is the first to start wheel spinning.

Thanks for all your advice.

Swapped the wheels round today using the spare as a middleman/wheel and that took a ferkin age, I'm not going to make that mistake again.

Drives like she always has once more
