Alignment- "radial pull" ?
Had my 86 coupe aligned... Car was pulling to right, alignment improved maybe 50%, I took back they checked out and said it was my tires. They called it "radial pull"? He couldn't really explain it other than it was the tires pulling car to right? Shop is reputable and has a history and knowledge of Porsches... Any ideas?

If the tires are unevenly worn it can pull in one direction. If the alignment was off it could have worn the tires that way.
Other things to look at are: - Is there is crown to the road it will cause the car to pull? - Are the tire pressures uneven? - Do both front wheels spin freely and evenly? If this doesn't explain what you are seeing then either the alignment is off or very likely-> the corner balance is off. You can swap the tires left to right to see how that effects the pull as that would reverse the effect. Make sure the tires are evenly inflated and find a really flat chunk of asphalt to test it on.

My 81SC did that too after an alignment and corner balance. Went away after I had new tires put on.

Tire pressure good, wheels spin freely, tested on a fairly flat road. Will try swopping tires and see what happens.

Most decent tire busters nowadays have a machine that can measure radial and lateral pull in the shop with the wheels off the car. My guy uses it and tells me which wheels to mount on which corner to counteract the opposite side. Read on
