I had mitchellin PS2's fitted all round, these were all worn and needed replacing. Three weeks back I had these replaced with a set of Goodyear F1 GSD3's which I'd had on the car a year or two before and was impressed with.
The week before the tryes were replaced I'd had the Defcons fitted at APS so it would need a full 4wd alignment. But they said to have the new tyres fitted first and go back for the alignment afterwards.
On driving away from the tyre fitters I noticed the car was pulling / drifting to the left quite a lot and that the steering seemed to want to go where it wanted more than staying true. I put this down to needing an alignment and carried on my way.
Since then the car has been back to APS and aligned so it's 100% spot on in that respect as far as I know, but again on driving home from the garage I was feeling the same issue with the steering.
I have now checked and double check the pressures, and also swaped the wheels front to rear and the issue is still the same.
The last thing I have done is to try my old wheels on the front end which still have mitchellin PS2's on them, even though they only have 1-2mm tread on them, and the car seemed much better agian.
So, it's looking like there is an issue with the new tyres, but having swapped front to rear and found no difference would mean at least 2 of them have a problem, which I find hard to believe. Could it just be the difference in tread pattern from a radial banding to a 'v' shape making this much difference? All seems odd as i've had the F1's fitted before the PS2's and never noticed any difference in the handling of the car in this way.
Any thoughts at all?
