Your tires need you as much as you need your tires. And a happy set of wheels can save you money at the pump and help you avoid accidents. In other words, there's a lot riding on them. Use this guide to make sure you and your tires are safely in sync.
tire maintenance 101
Tire neglect is a common factor in car accidents. The National Highway Traffic Safety Administration (NHTSA) estimates that nearly 1 in 10 crashes is tire-related. But here's the good news: many tire-related accidents could be avoided with some simple tire maintenance.
Inflate your tires properly
Tires often lose pressure over time, and underinflated tires can make your car 3 times as likely to end up in a severe crash, according to the NHTSA. Overinflated tires can be a problem, too.
So get yourself a handy tire gauge and check your pressure once a month (preferably when the tires are cool and have been sitting for an hour). Check your owner's manual for the correct PSI. You can also consult your tire placard – which is permanently sealed in your driver's side doorjamb, door post, glovebox, or on inside of the trunk lid. You can also check your owner's manual. It's important to know that the pressure indicated on the tire sidewall is the maximum allowed in the tire and shouldn't be used to determine the proper inflation pressure for your vehicle.
Track your tread
Your tire tread should be at least 2/32 of an inch deep for safe handling. Here's a trick to help you measure: stick a penny into a tire groove. If part of Abe's head is covered, you're OK. If you can see his entire copper dome, it's time to replace your tires. Why? In a 2012 NHTSA study, tires with treads shallower than 2/32" factored into significantly more crashes than their properly treaded counterparts.
Rotate and realign your tires
Rotate your tires every 6,000 to 8,000 miles. This helps balance the wear between the front and rear and prevents uneven deterioration. It's surprisingly easy for wheels to fall out of alignment — sometimes it's as simple as hitting a pothole.
Look for tire damage
Watch for severe damage like punctures, bulges, or cuts in the sidewall. If you're unsure whether the damage warrants a tire change, check with an expert from a tire shop or a repair shop.
Change all 4 tires
When it's time for new tires, some drivers buy only 2 at a time to save money. But this can leave you at risk. If you replace just the front tires, you could start fishtailing on sharp turns. And if you swap out only the back tires, you could lose traction in wet weather.
We recommend biting the (relatively minor but admittedly more costly) bullet and replacing all 4 tires at the same time. It could end up saving you money in the long run by helping you avoid a costly accident.
If you opt for only 2 new tires, however, experts recommend replacing the rear ones.
driving habits that can extend your tires’ lifespan
In addition to maintaining your tires, these good-driving tactics should help extend the life of your tires:
- Obey speed limits. Faster driving means shorter tread life (not to mention possible increases in car insurance rates if you get a ticket).
- Avoid sudden stops, starts, and turns. Burning rubber is a great way to quickly ruin those new tires — and it's an open invitation for any nearby cops.
- Avoid rubbing against curbs when parking. For all you city dwellers, we know finding an open space can be a long and grueling battle. But when you do find one, take an extra second to park slowly and save your tires from any sidewall cuts or punctures.
- Load your car with caution. Your car can only carry so much. Check your manual for your vehicle's load limits and stick to them.
