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.
To find the maximum load and inflation pressure, youâll need to check the sidewall of the tire. A speed rating also has a letter code, and that is immediately after the width and aspect ratio. Itâs part of the three-digit load/speed index. This is on the tire, immediately after the complete size designation. A Z-rated tire has no maximum speed â this rating is for more than 149mph.
