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.
You can make sure that the tread on your existing tires is safe by checking it at least once a month when you check your tires' air pressure. Start by culling out the riskiest rubber. Look for bald tires by checking whether any of the wear bars are flush with the tread's outer surface. Another way to check whether your vehicle's tires have reached their wear limit is to insert a penny into each groove, Lincoln's head down, as shown below. Replace the tire if the top of Abe's head becomes uncovered by any of the grooves.
