I JUST BOUGHT MY 2003 Z ABOUT 1 MONTH AGO IT HAS TWO DIFFERENT BRAND OF TIRES ON IT. I WANTED TO KNOW IF THAT WAS THE REASON FOR THE HUMMING AND WHAT ARE GOOD ALL SEASON TIRES TO PUT ON IT. THANKS

 

MAYBE.

It depends on the tire and how worn they are. What brand/model tires do you have?

 

Why are you yelling?

 

Welcome. Some tires are more noisy than others. Nothing wrong with the tires they are just noisy.

 

Lol, why do you think he's yelling?

 

Because typing in all caps indicates that a person is yelling.

 

This is due to "scalonated" tires. Is a type of wearing type on directional tires. You can confirm it by lifting the car and manually turn the wheel, you will see "steps" in the thread area. No solution, just new tires or select a non-directional tire. (even used)

 

Sounds like you're describing tire feathering, which was an issue on 2003 z's. The "roaring" between 15-30 miles an hour can be fixed with an alignment. If the inside of your tire is destroyed as a result of the feathering, you can take it somewhere and have them swap the tires so that the feathered part is on the outside if you want to get a little more life out of the tires.

 

WHAT? I CAN'T HEAR YOU OVER THE HUMMING SOUND YOUR TIRES MAKE

 

I am wondering if there is any truth that if you replace the control arms with after market ones that have more adjustment,that will resolved the feathering problem ?

 

Also is Nissan being pressured into a recall campaign to fix the problem at their expense as was done with 84,85,86, 300 injector recall ?

 

Do you hear the humming noise more when you slowdown, or does the humming noise become more pronounced as your speed increases?

If the humming noise is greater as you slow the car, it might be the “feathering problem.” That is a common problem with '03 models (as you own), but, this would be more a “roar” than a “humming” noise.

If the humming noise is there all the time (and maybe a little greater as you increase your speed), it’s probably the tire and its tread design. Generally tires with more stiff sidewalls may make more noise, but that isn’t true in all cases. Tire noise also differs depending upon the tread, tire compound-makeup, and even the tire manufacturer. For example, Michelin tires run very quiet, and Avon tires make a lot of noise.

The best comment on this tread:
Also… you might want to turn-off your all-caps key. “All-caps” is difficult to read.
