Is it always necessary to have wheels checked for proper alignnent by mechanics after changing new tires?

Answer 1

Yes I do maybe that is why I can get 80,000 on a set of Chinese tyres

Answer 2

No. you confuse it with balancing.
Alignment shout not be necessary unless maintenance schedule says due, anyway. Or, your old tires showed odd wear.

Answer 3

If you were having problems with tire wear before, sure.

Answer 4

Only if you or the person dismounting the old tires notice uneven tire wear. The best wheel and tire balancer in the world is still the Hunter GSP9700.

Answer 5

Nope. Changing tires because they are worn to bald is a fair long time. (for me,8 years) Wheel alignment is only needed if you hit the sidewalk curb hard every time you stop or you got many large potholes you hit at high speed. The steering goes wonky as the car drifts, instead of driving generally straight down the road. All roads have a hump in the middle (for water drainage) so the car drifts slightly to the left. It hardly ever goes completely straight down the road.
. So wheel alignments happen when the steering or front suspension changes(parts wear out and need to be replaced) Tires are not a mechanical part.

But new tires should be "Balanced">those lead weights on the rim of the wheel is to stop shuddering or vibration you will feel in the steering wheel with unbalanced tires.

Answer 6

No.

Changing tires is not related to change in the steering system or the suspension. If parts in the steering or suspension are damaged or worn, and then replaced, the caster, camber and toe should be checked and adjusted if necessary.

Same with rear on vehicles that don't have a rear drive straight axle.

When changing tires on wheels, they should be balanced. And they are also observed while on the balancing machine to make sure they run true and has no manufacturing problem. Once in a while, a new tire is found to be defective in some way.

Answer 7

I always have that done when I buy new tires to insure the alignment is right and to make the new tires last the longest they can.

Answer 8

Good idea. My tires are cupping because I didn't do it.

Answer 9

No, but it is certainly a very good idea. You want to protect your new investment!

However, it does not mean you HAVE to get an alignment. You can always take the approach of purchasing the new tires and having your vehicle aligned directly afterwords if you wish. One the new tires are mounted you will know whether or not an alignment is necessary. Guaranteed.

Answer 10

Necessary? No. Recommended? Yes...

Take a look at the old tires being removed and if there is any sign of abnormal wear. If you don't see any, you're probably ok but if there is any signs of inside or outside wear, or feathering of the rubber, definitely have the alignment checked before you ruin your new set of rubbers.
