But you can try to avoid these fates by checking your data use throughout the month. Each iPhone carrier in the U.S. (with one exception) gives you multiple ways to find out how much data you're using.
Hereâs how to inspect your tires: 1  The penny test: Put a penny with Lincolnâs head upside down into the groove of the tire. 2  If you can see all of Lincolnâs head, the tire is considered dangerous. 3  The less of Lincolnâs head you can see, the safer you are.
Use a tread depth gauge, or if you donât happen to have one of those laying around, try the âpenny test.â Insert a penny into the tire tread grooves with Lincolnâs head facing down. If you can see the top of Lincolnâs head, your tires are at 2/32nds of an inch or less of remaining tread.
