People Who Suffer Depression And Anxiety After A Traumatic Brain Injury May Have Damaged White Matter. Jun 16, 2015 12:00 AM By Ed Cara @EdCara4. Researchers from the University at Pittsburgh Medical Center may have figured out why people suffer depression and anxiety after a concussion.
How to Read Speed Rating, Load Index & Service Descriptions. Using a P195/60R15 87S tire size as our example, the 87S at the end of the size represents the tire's service description. A service description identifies the tire's load index and speed rating.
An S-rated tire is nominally capable of a sustained speed of 112 mph. I'm sure that if you went 115 mph, it's not going to blow up. Or even 120 mph. But wait -- the next speed rating (T) is at the 118 mph level, so there must be a rather defined line between those two speeds of what a given tire can handle.
