Tire Maintenance 101: How to Make Your Tires Last
Tires are your most safety-critical wear item. A few simple habits can double their lifespan and keep you from a dangerous blowout.
Most drivers replace their tires far earlier than necessary — or far later than they should. Both are expensive outcomes. Proper tire maintenance is simple, cheap, and directly tied to safety. Here's what you actually need to do.
Check Tire Pressure Monthly
Tires lose roughly 1 PSI per month naturally, and up to 1 PSI per 10°F temperature drop in colder weather. Running underinflated tires increases rolling resistance (hurting fuel economy), causes accelerated wear on the outer edges of the tread, and generates excess heat — the leading cause of tire failure at highway speeds. Running overinflated tires causes accelerated center tread wear and reduces the contact patch, harming wet grip.
Check pressure when the tires are cold (driven less than a mile). Use the PSI listed in your door jamb sticker or owner's manual — not the max PSI printed on the tire sidewall, which is the tire's maximum capacity, not your vehicle's recommended pressure.
Rotate Every 5,000–7,500 Miles
Front and rear tires wear differently. Front tires on front-wheel-drive vehicles wear significantly faster because they handle both steering and driving forces. Rotation moves tires to different positions on the vehicle to equalize wear. A standard rotation costs almost nothing at a shop and can add 20–30% more life to a set of tires. Set a reminder to do it every other oil change.
Get an Alignment When It's Needed
Misalignment causes tires to scrub against the road at a slight angle rather than rolling straight. The resulting wear pattern — called feathering, camber wear, or toe wear depending on the misalignment type — can destroy a tire in as few as 10,000 miles. Signs you need an alignment: the vehicle pulls to one side, the steering wheel is off-center, or you notice uneven wear on one edge of the tire. An alignment is inexpensive. Replacing a tire prematurely is not.
Inspect for Damage Regularly
Walk around your vehicle and look at your tires periodically. You're checking for: visible nails or screws embedded in the tread, sidewall bulges (which indicate internal structural damage and mean the tire must be replaced immediately), cracking in the sidewall rubber (common on older tires even with tread remaining), and unusual wear patterns that indicate alignment or suspension issues.
Know When to Replace
The tread wear indicator bars built into every tire are your minimum legal limit — when the tread is flush with those bars at 2/32", the tire must be replaced. But performance in wet conditions degrades significantly before you hit that limit. A tread depth gauge is inexpensive; anything under 4/32" in a wet or snowy climate is worth replacing. Also replace tires that are older than 6–10 years regardless of remaining tread — rubber compounds degrade over time.
Don't Mix Tire Types or Sizes
Mixing all-season and all-terrain tires, or running different sizes front and rear (outside of a staggered OEM fitment), creates handling imbalances and can damage your drivetrain on AWD vehicles. Replace tires in pairs at minimum — ideally all four at once on AWD systems.
