One of the reviews has something interesting to say


  These 27" and 26" tires are made to fit older 10 speed/english racer
  type bikes. You should remember that the 26"x1-3/8" size predates the
  MTB era by at least three decades, they came first. If you have an old
  Raleigh three speed or a 1970s Peugeot then these are the tires you
  need in the appropriate rim size. In general, if you have a Mountain
  bike or your bike is less then 20 years old, these are probably the
  wrong tires for you


According to Sheldon, mountain bikes use "decimal" sizes, such as 26x1.75 and some older road bikes from the 70s use "fractional" sizes like 26x1-3/4. 

Although it appears you bought 1.375 which is a decimal size, so it should fit modern bikes. However 1.375 = 1-3/8 which is the size the review is talking about. According to Sheldon, 26x1-3/8 would have a BSD of 597mm or 590mm while newer 26 inch bikes have a BSD of 559mm, making the old sized tired too big for modern rims.

Are some tires safer than others?
I was planning to record months ago, with my electric guitar, and yesterday I got myself a guitar rig software and bought some 1/4 to 1/8 adapter jack so that I can plug in unto my laptop's mic hole.

Whenever I plug my guitar cable to the 1/4 to 1/8 adapter then to the laptop I can't hear any sound (past the clicking sound you hear) but when I plug the cable almost halfway of the adapter's body (before the clicking sound) I can hear sound when I play and there's some loud buzzing sound involved.

Any explanations as to why this is happening?
