Tires: Loud Noise from 235/70 R16 104T Continenta Radial, directional tires, radial tyres


Question
QUESTION: I put Loud Noise from 235/70 R16 104T Continenta Radial tyres on Mazda Tribute 2006. Loud noice as you reach 40 miles/hour and higher. Is it the tires of something else. Just got alignment and balancing done. Runs smooth at even 80 miles/hour but loud. Please explain.

ANSWER: Deep,

Trying to diagnose a noise over the internet is very difficult.  I doubt if I can tell you what the source of the noise is, but let's try this:

Rotate the tires.  If the noise moves, then it is probably the tires.  Describe what the noise sounds like in a followup post

If the noise doesn't move, it probably isn't the tires - and I probably won't be able to help you.

QUESTION: I took it to a local tire shop. One said they are mounted wrong. Other said the truck they came out of had bad struts and that damaged the tires and the damaged tires are making the noise. Please explain.

Answer
Deep,

You said "One said they are mounted wrong."  

Look at the sidewall of the tires.  If there is an arrow, they are directional tires - and the arrow should be pointed in the direction of rotation.  If the tires say "This side out" or words to that effect, then these are asymmetrical tires and the tires have to be mounted such that the "out" side is .....ah....outside.

However, most tires don't have either of these markings, so they can be mounted in any configuration.

However, none of these three should of itself cause a noise.

You also said "Other said the truck they came out of had bad struts and that damaged the tires and the damaged tires are making the noise."

This is possible - the bad struts could cause the tire to develop irregular wear - but it is also possible that a misalignment condition could also cause irregular wear.

As I said earlier - to be sure you need to rotate the tires and see if the noise moves.  If it doesn't, it isn't the tires - it would be something mechanical in the vehicle.
