Wheel alignment - technical data

Hello friends,

I have problem with wheel alignment. Tire tread wear is not the same inside and outside.
I went to my local wheel alignment service but the man didn't know technical data of pacifica 2017. It is the car from USA and he do not have this car in option car which can choose (I don't know how it explain in English). He need to know all technical data which relates to wheel alignment - degree, mm, Tilt angle, wheel alignment 0 or - or + (how many mm). I don't know how it all name, but it should be data values from. Mm or degree to. Mm or degree.
I am waiting for yours reply.
Have a nice day,
Pawel
