measuring bike tire wear

 

I put a michelin speedium 2 tire onto my rear wheel last summer.  I found out after a few miles that these guys look like they wear out quickly.  They feel soft and tacky, though, which is kind of nice.  I don’t recall getting a lot of flats on this tire throughout its lifespan.  here’s what the tire looked like after about 2500 miles (and after AIDS LifeCycle):

 

 

2500 miles doesn’t seem like a lot for a tire, but I didn’t have high expectations – I purchased a pair on sale for $12 each.

I still had the other new tire, so out of curiosity, I weighed the two:

I know there can be manufacturing variations in tire weight, but it’s pretty neat to quantitatively measure about 20 grams in tire wear.  I liked the tires.  I’ll probably purchase another pair of michelins next.
