Summary
  • New car tires can wear out prematurely because of bad driving habits, a misaligned camber or toe, tire overinflation or underinflation, and low tire tread wear ratings. It’s not advisable to drive with worn-out tires.
  • All-terrain tires usually last between 40,000 and 70,000 miles.
  • You must consider the type, size, and speed rating of the tires you plan to buy for your vehicle.
  • Get the most of your tire’s service life by checking the pressure, inspecting the components, and monitoring the tire pressure monitoring system (TPMS).

New or factory car tires often wear out faster than replacement and aftermarket tires because they’re made of soft rubber material. This makes them more susceptible to wear and tear. That’s usually the reason why new car tires deteriorate quickly, but it’s not the only one.

5 Reasons Why New Car Tires Wear Out Quickly

Aside from their material, the tires of brand-new cars might wear out quickly due to the following issues:

Underinflated or Overinflated Tires

If tires don’t have enough air, their tread flexes abnormally as they rotate, which causes excessive friction and wears them out faster. The friction can also overheat the tires, resulting in tread separation and tire blowouts. Meanwhile, overinflated tires will wear the tread out in the center.

Tire pressure monitor systems (TPMS) became mandatory in 2007, so check your tire pressure if that system sounds a warning or illuminates a tire light.

Overinflated tires will wear the tread out in the center.

Misaligned Toe or Camber

Toe refers to the parallelism of the wheels to each other, while camber refers to the tire angle with respect to a perfectly flat road. If they’re misaligned, they often cause uneven tire wear. On a new car, this will only be an issue if the vehicle wasn’t properly aligned on the assembly line.

Toe misalignment usually creates a feathered wear pattern across both front tires and the inner shoulder wear on both tires. On the other hand, camber misalignment usually produces uneven tire wear on one side of the tire tread. But again, unless you’ve hit a pothole or curb and knocked the front end out of line, this won’t be a problem on a new car.

Bad Driving Habits

Hard cornering, standing on the brakes, and other aggressive driving habits can cause tire wear, usually due to uneven friction and weight distribution.

For example, if you take a corner too quickly, you’ll put too much pressure on your tires. The force wears away at their tread, and if you do it often, you might notice rounding on the tire’s shoulders when you look at it straight on.

These habits can accelerate tire wear on a new car, so think about the tires while you’re driving a new car.

Tire Quality

Tires with high tread wear ratings (over 300 or 400) last longer than tires with low tread wear ratings (200 or less). Some new cars have tires with low tread wear grade.

Pro Tips are nuggets of information direct from ASE-certified automobile technicians working with CarParts.com, which may include unique, personal insights based on their years of experience working in the automotive industry. These can help you make more informed decisions about your car.

Pro Tip: Familiarize yourself with tread wear codes and check the tires before you buy the new car so you’ll know what to expect.

Can Worn Ball Joints Cause New Tires to Wear Out Faster?

A bad ball joint can cause uneven tire wear because they affect the wheels’ alignment. The inner and outer edges of the tires will wear out faster than their other surfaces due to the misalignment.

Of course, new cars shouldn’t have worn ball joints, so that won’t be the reason new car tires wear out. Also, ball joints don’t typically cause tire wear unless they’re dreadfully worn to the point of falling apart.

Can You Drive With Worn-Out Tires?

You can drive with worn-out tires, but it’s not advisable because they increase the risk of accidents. Worn tires reduce braking efficiency, which can make driving on wet roads risky. On top of that, low-tread tires are also vulnerable to blowouts.

How Long Do Tires Usually Last?

All-terrain tires typically last from 40,000 to 70,000 miles. But manufacturers are careful not to give a specific mileage claim because various factors can affect tire lifespan. The tread wear rating on a tire’s sidewall provides a relative index rating of tread life in comparison to other tires.

Why Are Getting Good Tires Important?

Tires absorb shock when driving over uneven surfaces and provide traction between the wheels and the road. The part that connects to the ground is called tread, and it’s essential in braking.

Tread depth is usually around 11/32 in. deep on new tires, but that could be between 9/32 in. and 15.32 in. depending on the manufacturer. If the tread is worn-out, it can’t provide enough traction for braking, which increases the vehicle’s stopping distance.

What to Consider When Buying Tires

Don’t base your tire choice on looks alone. Keep the following factors in mind to get the best tire replacements for your ride:

Type

When in doubt, pick the same type of tire that your vehicle came with. But if you want to try something different, like all-season tires or touring tires, make sure you research them well before buying anything.

Size

Make sure to buy the same size as the original one. Tire size is critical for vehicle handling, and it affects your ride’s brake effectiveness, headlight aiming, vehicle height, acceleration potential, and speedometer calibration.

Speed Rating

Get tires that have the same speed rating as your original tires. If you install tires that are incompatible with your ride, you might have trouble with cornering and handling.

How to Maximize Your Tire’s Service Life

Make the most of your tire’s service life by following these practices.

Check the Tire Pressure

Make sure the tire pressure stays at the right range. It should be between 32 and 36 PSI, but this value may vary depending on the vehicle. This pressure range keeps the tires firm enough to support the weight of your vehicle while avoiding straining the tire’s materials.

Inspect Tire Components

Check the parts that are crucial for wheel alignment, like the ball joints, regularly. If your ball joints have built-in wear indicators, you can check joint play with the weight of the vehicle on the wheels. But if they don’t, you might have to raise the suspension to check.

You can also take your ride to an auto repair shop to have its wheel alignment checked.

Check the TPMS

The tire pressure monitoring system (TPMS) has an indicator on the dashboard that lights up when a tire has low pressure.

Underinflated tires usually have a smaller radius compared to tires that are properly inflated. The wheel speed sensor will detect a difference if the inflation pressure is 12 PSI or more. It will then alert the ABS (anti-lock braking system) controller to turn on the low tire pressure warning lamp.

An indirect tire pressure monitoring system also checks the rotating speed of diagonally opposed wheels. It compares different readings and triggers the TPMS warning light if it identifies issues.
