How to choose the right tire size for your vehicle?
Choosing the correct tire size for your vehicle is extremely important for proper handling, ride comfort, and safety. Here are some tips on selecting the right tire size:
Check your vehicle's door jamb or owner's manual
Your vehicle's recommended tire size is usually listed on a sticker inside the driver's side door jamb or in the owner's manual. This is the ideal size determined by the vehicle manufacturer.
Understand tire sizing
Tire sizes follow a standard format - the tire width in millimeters, aspect ratio, construction type (R for radial), and rim diameter in inches. For example, 255/35R18 - the tire is 255mm wide, has a 35% aspect ratio, is radial construction, and fits on an 18 inch rim.
Consider speed rating
The speed rating indicates the maximum speed a tire can handle. Most passenger vehicles use H, V, or Z ratings. Higher speed ratings like Y or W are used on performance vehicles.
Check load index
The load index number shows the maximum load carrying capacity of the tire. Make sure this matches or exceeds your vehicle's weight capacity.
Review options for your vehicle
Besides the OE size, there may be alternative tire sizes that work for your vehicle. These give you more choices but should have the same overall diameter to maintain proper speedometer and odometer accuracy.
Following these guidelines will help you select tires that are safe, fit properly, and meet the handling and ride needs of your vehicle.

Follow the recommended rotation pattern in your owner's manual to promote even treadwear. This is usually every 6,000-8,000 miles.
Inspect tires regularly
Check tread depth monthly and replace tires when they reach 2/32" of remaining tread. Also inspect for any damage like cuts, cracks or bulges.
Drive responsibly
- Accelerate, brake and steer gradually
- Avoid potholes and curbs
- Don't overload the vehicle or tow beyond capacity
Following these tips will keep your tires in optimal condition so you get responsive handling, short braking distances, and mileage out of your high performance summer tires.
How to properly rotate your tires for maximum lifespan?
Regular tire rotation helps distribute wear evenly across your tires so they last longer. Here are some tips for getting the most out of tire rotation:
Follow the vehicle manufacturer's recommendation
The owner's manual will specify the recommended rotation interval and pattern. This is usually every 6,000-8,000 miles for most vehicles.
Use a crossing rotation pattern
For front-wheel drive vehicles, use a front-to-rear crossing pattern so front tires end up on the opposite rear side.
For rear-wheel drive, rotate the rear tires straight forward and cross the fronts to the opposite side.
Torque wheel nuts to spec
Tighten the wheel nuts to the vehicle manufacturer's torque specification using a torque wrench.
Inflate tires to proper pressures
Check and adjust tire pressures after rotation. Refer to the vehicle door jamb sticker or owner's manual for proper inflation levels.
Inspect tires
Do a thorough inspection of the tires during rotation. Look for any signs of abnormal or uneven wear and damage. Address any issues promptly.
Following these steps for tire rotation will help maximize the life of your tires, maintain vehicle handling, and give you thousands of extra miles before needing new tires.

How to know when it's time to replace your tires?
It's important to replace tires before they become dangerously worn. Here are some signs that indicate it's time for new tires:
Tread depth
Check tread depth regularly with a penny or tread depth gauge. Place the penny into the tread grooves with Lincoln's head upside down. If you can see the top of Lincoln's head, the tread depth is less than 2/32" and it's time to replace the tires.
Tire wear bars
Look for the built-in wear bars between the tire treads. When they become flush with the rest of the tread, there is less than 2/32" of tread left.
Visible damage
- Cuts, cracks, bulges or bubbles in tire sidewalls
- Punctures, cuts or gouges in the tread area
- Separation between tread and sidewall
Age of tires
Regardless of tread wear, it is recommended to replace tires that are 6-10 years old due to rubber breakdown.
Poor handling and braking
If you notice increased swerving, longer stopping distances, or uneven tire wear, the tread is likely worn out.
Tire pressure fluctuations
Consistently low tire pressures could indicate a nail, puncture or slow leak that makes the tire unsafe.
Replacing tires promptly when these warning signs appear reduces the risk of blowouts or skidding accidents. Investing in new tires is far less costly than an accident.

How To Choose The Right Tire Size For Your Car?
Choosing the right tire size for your car is crucial for optimal performance, safety, and fuel efficiency. To determine the right tire size for your car, you can find the information inside the driver's door, inside the fuel flap, or inside the glove compartment. Alternatively, you can consult your vehicle documentation and tire manufacturer specifications. The recommended tire sizes for your car are outlined in the documentation supplied with your vehicle. Compatibility is determined according to its outer dimensions, diameter/rolling circumference, and width, and labeled as a standardized tire size indicator on the sidewall. The speed index rating is also a relevant factor when choosing a tire. The tire's speed capability must be at least equivalent to the top speed of the vehicle. Its speed rating indicates the maximum permissible speed (at full load) of a tire, and whether it's appropriate for your car. Make your tire size selection in strict accordance with vehicle documents and tire manufacturer recommendations. If the combined wheel and tire diameter aren't correctly matched, there may be drastic differences in ride height and speedometer readings.
What Is The Difference Between Tire Width And Aspect Ratio?
Tire width and aspect ratio are two important measurements that determine the size and performance of a tire. Here are the differences between tire width and aspect ratio:
Tire Width:
Aspect Ratio:
In summary, tire width is the width of the tire from side to side, while aspect ratio is the height of the tire's sidewall measured as a percentage of tire width. Both measurements are important in determining the size and performance of a tire.
How Does Tire Width Affect The Performance Of A Car?
Tire width affects the performance of a car in several ways, including:
- Contact patch: A wider tire will have a larger contact patch with the road, which translates into better braking and cornering performance, all other factors being equal. This also grants the tire better traction. However, acceleration may be slightly slower due to the increased contact patch and resulting gain in rolling friction unless the previous tires could not handle the engine's power effectively and lost traction as a result.
- Fuel economy: Wider tires result in a slight decrease in fuel economy. Narrower tires offer less traction and grip at the limit but are a popular choice for economy cars because they provide better fuel economy due to their smaller contact patch.
- Rolling resistance: A larger width will contribute to increasing friction, which has a positive effect on road holding. However, rolling resistance is also increased, which can compromise speed during acceleration, depending on the torque of the car.
- Handling: The tire width affects the handling of the car. A wider tire will offer more grip than a narrow one on a dry road, but the risk of aquaplaning will be higher with wide tires. Increasing the tire diameter will raise the chassis height and the center of gravity, which can increase roll and oscillations, making the car handle differently and potentially become more cumbersome.
In summary, tire width affects the contact patch, fuel economy, rolling resistance, and handling of a car. A wider tire provides better grip and traction, but it can compromise acceleration and fuel economy. The tire width should be chosen according to the car's characteristics and the driver's preferences.
How Does Tire Width Affect Fuel Consumption?
Tire width affects fuel consumption in the following ways:
- Rolling resistance: Wider tires create a larger contact patch, which increases rolling resistance. This means that the engine has to use more power and fuel to maintain speed, resulting in lower fuel economy.
- Wind resistance: When a car is driving at higher speeds, it experiences higher wind resistance, which means lower fuel economy. Wider tires create more wind resistance, which can negatively affect fuel economy.
- RPM: Changing the diameter of a vehicle's tire can impact its overall performance, including fuel economy. Smaller displacement engines produce less torque per revolution and must spin at higher RPMs to make power. If the tire is too small, the engine will be spinning faster than necessary to maintain speed, thus wasting power and fuel.
- Tire tread: Tire treads can impact fuel economy because 35-50 percent of the rolling resistance of a tire comes from the tire tread. Some tread compounds can reduce rolling resistance a great deal. In addition, the shallower the tread, the more fuel-efficient the tire will be.
- Tire size: Larger tires decrease fuel economy because they are heavier, while smaller tires increase fuel efficiency. Bigger tires also have a higher rolling resistance than smaller tires, which means they require more resistance and effort to get them rolling. So, in stop-start traffic, the smaller tire would be the better option because less power is needed so it will get better mileage. However, for freeway driving at high speeds, having larger tires can help increase the vehicle's fuel efficiency.
In summary, tire width affects fuel consumption by increasing rolling resistance, wind resistance, and RPM. Tire tread and tire size also play a role in fuel economy. It is important to choose the right tire size and width for your vehicle to optimize fuel efficiency.
