I keep getting flat spots all the way around the center of my rear tire. Is this common? I dont remember this happening before. The tires got 700 miles on it .I ride everyday but when it rains.

 

What brand/model of tire?
year model of bike?

 

For starters are you over inflated and how hard are your downshifts? Make of tires would help out, throw in the year, model of your bike.

 

04 deuce with avon cobra tires inflated to 40-42lbs. I don't downshift hard

 

are you saying multiple flat spots or a flat strip down the center

 

Flat strip doen the center. Is this common

 

that's where your tire rides unless you do twisties alot

 

How much of a flat strip down the center we talking? On 700 miles you should see a wear pattern but still good tread. Any chance you can throw a picture of the tire and what you're talking about up?

 

a lot of highway type riding, or not so many twisties?

 

Last year my sons bike was riding very funny like the rear tire had flat spots . And after I road it to work to trouble shoot the problem for a week . I found out it was a broken lower motor mount . We replaced it and the thump thump thump from the rear wheel was gone .
