Steering alignment

I replaced two of the tires which were really worn out and i did not
want to take a chance with the buffalo winter. The other two tires
were brand new when I had purchased the car 6-7 months back. I had the
new tires put on the front and the old ones at the back. But having
the new tires on the front dis-aligns my streering. Once I put the old
tires back on the front, the streering again aligns properly. Now the
question is why would only the new tires create an alignment problem?
Should I get a steering alignment done with the new tires at the
front? If I do that, would it dis-align the steering again when I
rotate the tires?

 

1. please learn to cross post.
2. make? model? year? continent?

 

Usually when you purchase new tire you get an alignement done,but that's my
vision of things.
If you buy "budget" tires i guess it is not really necessary but if you buy
expensive ones(like i do) you get it aligned.

Good luck!

P.S. if you get an alignement make sure everything is tight and
sound(bearings,bushings,tie rod,ball joints)if not,they wont do it.You will
have to get that fix before.
