HEY WAZZUP!! I AM NEW TO CBR FORUMS!!! I HAVE A 00 CBR 600 F4. I HAVE ABOUT 4700 MILES ON THE BIKE AND TIRES. THE FRONT TIRE I AM RUNNING THE RIGHT TIRE PRESSURE BUT IT IS FEATHER UP ONLY ON THE THE FRONT TREADS. I WAS WONDERING IF ANYONE COULD TELL WHAT CAUSES THAT SO I CAN FIX MY PROMBLEM WITHOUT HAVE N TO BUY A NEW TIRE

 

4700 is pretty good mileage for sportbike tires. Itthe tire isout of balance, or if anything in the front end is loose, or if you ride wheelies a lotit will feather the tire, and once it starts to feather it gets progressively worse. Even if you find something else causing it, you should still get new tires.

 

Wow, all caps. Not to thread jack, but what is tire feathering?

 

tire featheringis just what i call it idk if thats what u could call it but it's just where my treads are weraing un evenly the tread is high on the front side and low on the back side!!!

 

Run your tires at the max pressure that's on the sidewall of the tires - for better wear and mileage.

 

Why are you whispering?[8D]

What do you mean "high on the front side and low on the back side"? Does that mean when you spin the tire halfway around that it's 'low on the front and high in the back'? Post a pic.

 

i think you're referring to 'cupping'...where it's just all bulbous looking, very out of round, like long time ago in the robotech cartoon when the centurion ships got blasted by a cannon and got all bubbly before it blew up.

it's natural at the end of the tire's life, which 4700 is about right. if it happens around 2k or less then you have alignment/suspension issues.

 

LOL......... +1

 

I'm watching a DVD where he talks about suspension problems causing excessive tire wear and how to diagnose. Sorry, I'm not so studied up on it yet.
