Hmm, that is true, you might lose a bit of clearance between sidewall and strut when the strut is bent. I'm not sure if they do it on the car, I believe they do.

Fook, 45 psi reduces side wall flex. Used to find scrub marks almost to the rim. Apart from that, I dunno, it just seems to work well.

 

P.S: Bending the struts is called camber correction. :)

Rob: I don't seem to have that problem much on the front, mostly in the back. When I was running the Simex SM6000 tyres even with 48psi in the rear I was still getting scrub marks almost to the rim on the back wheels (going around the Paperclip)!!!
