Car pulls

Jo,
I am glad that helped. I feel that 32/34 is the best starting point for best handling, but is a bit low to maximize protecting your wheels if you drive rough roads. If the roads are bad, then you could add 2-3 psi at each end without compromising handling very much. (In fact, if you don't do much spirited driving to get the tires fully warmed, that may be a better cold pressure for handling.)
The reason that swappnig tires can change things is that tires are not precision made. There are belts that overlap and shift in the manufacturing process. No two tires are alike and they will often have a bit of pull in them. Also, you could look at and swap the rear tires as well. They can cause a side thrust.
A bit more toe-in will help stability, but at the expense of a crisp feeling turn-in. I am sure Steve will add to this.

I see what you mean about the tires likely to be slightly different. Will try the extra pressure and swapping the rears.
Just noticed your Radical is built here in Peterborough only a couple of miles from where I live. Perhaps I can be of assistance to you one day - I could go to the factory on your behalf. You have a bed for the night at my place if you ever visit the factory - I can then repay your help with a beer or two.

Apparently, the first alignment technician had difficulty in bringing the left rear camber and kinetic toe within spec (originally the car was out of spec on nearly every count).

Have you spoken with the previous owner?
HTH, cheers, Maurice

I am currently experincing the exact same problem with my P-zeros on Fikses. Same thing, car pulls to the right like Charlton Heston and the steering wheel is canted 5 degrees. I took the car to Mike Schatz for a complete alignment, and it was not cured. He suggested that I had a tire problem. I then swapped my wheels out to the stock wheels with Kumho R compunds, and STILL have the same problem.
Car goes back in Wednesday for further investigation.
