Tomorrow I have an alignment appointment but I dont know which tires to have on the car for the alignment.

I have a set of 255/40/17 race wheels and then the normal 235/45/17 street wheels.

I am guessing (but not sure) that the change of tire size with throw off the alignment. Which tires wheels would you use?

BTW I will be going for -1.8 F and -1.5 R with zero toe.

I am a very aggresssive driver and attend quite a few HPDE events.
