Car wheel alighment for my 2004 NIssan Station Wag

Is there any reason to be this the roads we are driving often wreck our cars.what are the other reasons for me to learn what causes so often. aside from the type of tyres?
Thanks we have not long put 4 new tyres on.

tyres will not affect a wheel aignment. a wheel alignment will affect tyres. angle parking is worst thing if you run into the kerb.deep potholes will also knock it out

Average new zealand roads 5 to 10 000 k's is enough to merit checking.
And ALWAYS use driveways NEVER go up n down square kerbs

if you are having issues with it going out or alignment then think about changing where you get it done, was getting mine done at local bridgestone and blew a set of AT tyres in a year and a half due to the sides getting chewed out, felt like I got about 10 alignments done in that time at $100 a pop and until the guy backed out of his shop with his roller door down, bending my radio aerial then laughing it off thinking I would not care!

New tyres and got alignment done elsewhere and 2 years latter the tyres are still wearing perfectly!

so do shop around!
