wheel alignment question for technicians....

Is it better to have a wheel alignment before buying new tires or after? If the old tires are on the car, the tech may see where adjustment is needed based on bad tread wear...or is the alignment machine so sophisticated that he would pay no attention to tire conditions. If new tires are already on the car will the alignment process "fit to suit" the new tires? Maybe having the alignment before having new tires put on would be a waste, since if the tire installers are heavy handed, perhaps they'll knock it out of alignment. Don't want to over-think this, but it's $90 and I want the alignment to last. Appreciate any opinions.

Tires are integral to the suspension angles that the alignment machine measures, and a bad set of tires will drastically affect these. Aligning a car with worn tires will compensate for them, so then when new tires are installed the previously adjusted settings will now have changed. So, an alignment done before new tires are installed is a waste and will serve no purpose.

Thanks for the heads-up on that...will align right after I purchase my tires.
