Over-inflated Tires. Tire tread wear in the center of the tread pattern tells you that the inflation patterns are too high. Too much pressure can cause the contact patch to shrink and the center of the tire to carry the entire load. Under-inflated Tires.
Apple Products and Services. Most Thunderbolt hubs won't work. In fact, I'm not sure if any will work not. (I've never been in a position to try this with a MacBook Air.) I found several instances from people who thought it would, bought a Thunderbolt hub, then found out it wouldn't work. The best way to do it, is to plug one monitor into the Thunderbolt port and another one into a USB port. To do this you will need the appropriate adapters. What adapters you need depends on what kind of monitors you are hooking up, and what ports they have. According to Apple, you can hook up a total of two external monitors to a MacBook Pro.

The adapter is just for video, and thus no other USB devices (carrying power or data) can be connected to the MacBook if itâs in use. There are several DisplayPort (and HDMI) cables, but they all require a monitor to have an adapter plug. Appleâs monitors have either a hard-wired Mini DisplayPort or Thunderbolt cable (which uses the same form factor as Mini DisplayPort) with a jack on the end.
