IS IT TRUE THAT NEW INSTALLED TIRES NEEDS TO BE WHEEL ALIGNED ALWAYS?

yes i do believe that

IT IS NOT TRUE, YOU DON'T ALWAYS NEED AN ALIGNMENT...BUT IT MAY BE NEEDED IF YOU HAVE TOO MUCH TOE IN OR OUT, OR EXCESSIVE CAMBER WEAR ON YOUR OLD TIRES.

There are several variables, how long since your last alignment, driving habits and conditions. How did the old tires wear? Does the new tire warranty call for it? How does your car drive, ok? Does it pull to one side? The list goes on. So no you do not need to have it aligned every time. I guess it is up to you! But to be sure........

As long as you don't drive the vehicle over bumps , or curves (with bumps) or down hills(with bumps), or on streets(with potholes) or more than 100 miles a year (give or take 10,000) you don't HAVE to do anything to maintain your vehicle. HOWEVER........as stated by others it may be needed due to normal wear of suspension items causing a shift in adjustments. IF you have a trustworthy shop looking at it and they've noticed poor wear , or it's been over 12,000 miles since last check , it would be advisable.
