Can I Put 17 Rims Instead Of 16? | Wheel Upgrade?

Yes, you can often put 17-inch rims on a vehicle originally equipped with 16-inch wheels, but careful planning and specific measurements are critical for safety and performance.

Many drivers consider changing their vehicle’s wheels for various reasons, from a fresh look to improved handling. The idea of moving from 16-inch rims to 17-inch ones is a frequent topic in our shop.

It’s a modification that can work well, but it demands a solid understanding of how wheels and tires interact with your car’s systems. Let’s break down what you need to know before making the switch.

The Basics: Understanding Wheel Upsizing

Upsizing your wheels means fitting larger diameter rims than what came from the factory. When you increase rim diameter, you typically decrease the tire’s sidewall height to maintain a similar overall tire diameter.

This balance is key to keeping your vehicle’s speedometer accurate and its safety systems functioning as intended. Think of it like adjusting a recipe; changing one ingredient requires careful adjustment of others.

Why Go Bigger? The Lure of 17-Inch Rims

There are several compelling reasons why drivers choose to upgrade to 17-inch rims. The visual impact is often the first thing people notice.

Aesthetic Appeal

Larger wheels can give a car a more aggressive, sporty, or premium look. They fill out the wheel wells better, changing the vehicle’s stance.

It’s a popular way to personalize your ride and make it stand out.

Handling Characteristics

With larger rims usually come lower-profile tires. These tires have shorter, stiffer sidewalls.

Stiffer sidewalls reduce tire flex during cornering, which can translate to sharper steering response and improved handling. This can make the car feel more connected to the road.

Brake Clearance

Larger rims can sometimes provide more clearance for bigger brake calipers or rotors. This is particularly relevant if you plan on upgrading your braking system.

The extra space prevents components from rubbing or interfering with each other.

Can I Put 17 Rims Instead Of 16? — The Technical Deep Dive

Answering this question involves careful measurement and understanding several critical vehicle specifications. It’s not just about the rim diameter; every aspect of the wheel and tire package matters.

Maintaining Overall Tire Diameter

This is the most critical factor. The total outside diameter of your new 17-inch rim and tire combination must remain very close to the original 16-inch setup.

A general rule is to stay within a 3% variance of the original diameter. Deviating too much causes speedometer errors, affects ABS, traction control, and electronic stability control (ESC).

Your car’s computer relies on precise wheel speed readings. Significant changes disrupt these calculations.

Bolt Pattern

The bolt pattern, or lug pattern, must match exactly. This refers to the number of lug nuts and the diameter of the circle they form (PCD – Pitch Circle Diameter).

For example, a 5×114.3mm pattern means five lug nuts on a 114.3mm diameter circle. An incorrect bolt pattern means the wheels simply won’t mount safely.

Offset and Backspacing

Wheel offset is the distance from the wheel’s mounting surface to its centerline. Backspacing is the distance from the mounting surface to the wheel’s inner edge.

These measurements determine how far the wheel sits inward or outward in the wheel well. Incorrect offset can cause the tire to rub against suspension components, fender liners, or the fender itself.

It also influences steering feel and can put undue stress on wheel bearings and suspension parts. Some vehicles are very sensitive to offset changes.

Center Bore

The center bore is the hole in the middle of the wheel that fits over the vehicle’s hub. Ideally, this should be a direct match (hub-centric fitment).

If the new wheel’s center bore is larger than the vehicle’s hub, you will need hub-centric rings. These rings fill the gap, ensuring the wheel is centered on the hub, not just by the lug nuts.

Without hub rings on a larger bore wheel, vibrations can occur, and lug nuts can loosen. This is a safety concern.

Wheel Weight

Larger and heavier wheels increase unsprung weight. Unsprung weight refers to the mass of components not supported by the suspension, like wheels, tires, and brakes.

An increase in unsprung weight can negatively impact ride quality, acceleration, braking performance, and fuel economy. Your suspension has to work harder to control heavier wheels.

Load Rating

The load rating of your new 17-inch rims and corresponding tires must meet or exceed the vehicle’s original equipment manufacturer (OEM) specifications. This is critical for safety.

The vehicle’s door jamb sticker provides crucial information on original tire size, load index, and recommended tire pressure. Always refer to this sticker.

Typical Wheel & Tire Size Transformation

Here’s a simplified illustration of how a common 16-inch setup might translate to a 17-inch setup while maintaining overall diameter:

Original Setup	New 17-inch Equivalent
205/55R16	205/50R17
215/60R16	215/55R17
225/50R16	225/45R17

These are examples; precise calculations are necessary for your specific vehicle. A tire size calculator is a useful tool for this.

The Crucial Role of Tires: Matching Your New Rims

When you change rim size, you absolutely change tire size. This isn’t an optional step; it’s fundamental to the conversion.

Lower Profile Tires

To keep the overall diameter consistent, a 17-inch rim requires a tire with a shorter sidewall. This is often called a lower-profile tire.

For example, if your 16-inch wheels used 205/55R16 tires, a suitable 17-inch tire might be 205/50R17 or 215/45R17. The middle number, the aspect ratio, decreases to compensate for the larger rim.

Impact on Ride Comfort and Noise

Lower-profile tires generally offer a firmer ride because there is less rubber to absorb road imperfections. You might notice more road noise and feel bumps more directly.

This is a trade-off for the improved handling and aesthetic often associated with larger wheels. Consider your daily driving conditions and preferences.

Tire Pressure Monitoring System (TPMS)

Modern vehicles are equipped with TPMS. When changing wheels, you’ll either need to transfer your existing TPMS sensors to the new 17-inch rims or purchase new compatible sensors.

New sensors will need to be programmed to your vehicle’s computer. This ensures your tire pressure warnings function correctly, a safety requirement by NHTSA.

Potential Pitfalls and What to Watch For

While upsizing can be beneficial, there are common issues that arise from improper fitment. Being aware of these helps you avoid costly mistakes.

Rubbing Issues

The most common problem is the tire rubbing against the fender, fender liner, or suspension components. This usually happens during turns, over bumps, or when the suspension is compressed.

It’s a sign of incorrect offset, tire width, or overall diameter. Rubbing can damage tires and vehicle parts.

Speedometer Inaccuracy

If the new tire’s overall diameter differs significantly from OEM, your speedometer will read incorrectly. A smaller diameter tire will make your speedometer read high, a larger one will read low.

This can lead to unintended speeding tickets or miscalculations of fuel economy. It also affects the accuracy of your odometer.

ABS and ESC Malfunctions

Anti-lock Braking System (ABS) and Electronic Stability Control (ESC) rely on accurate wheel speed sensor data. A significant change in overall tire diameter can confuse these systems.

This can cause them to activate incorrectly or fail to activate when needed, compromising safety. Modern cars are highly integrated.

Ride Quality Degradation

As mentioned, lower-profile tires transmit more road imperfections. If your car is already stiffly sprung, larger wheels and lower-profile tires can make the ride uncomfortably harsh.

Consider the type of roads you typically drive on. A smoother ride might be sacrificed for aesthetics or handling.

Increased Wear on Components

Changes in wheel offset can alter the scrub radius, affecting steering geometry and potentially increasing wear on wheel bearings, ball joints, and other suspension components over time.

Heavier wheels also add stress to these parts. It’s a subtle effect but worth noting for long-term vehicle health.

Ensuring Compliance and Safety

Making any modification to your vehicle’s wheels and tires requires attention to safety standards and regulations. Your well-being on the road is the top priority.

Professional Installation is Key

We always recommend professional installation and verification. A reputable tire shop or mechanic can ensure correct fitment, proper torqueing of lug nuts, and accurate TPMS programming.

They have the tools and expertise to measure clearances and advise on the best tire size for your new rims. This avoids common errors.

Checking OEM Specifications

Always consult your vehicle’s owner’s manual and the door jamb sticker for original tire and wheel specifications. This information is your baseline for any modifications.

The sticker provides crucial details like recommended tire size, load index, speed rating, and inflation pressures. Adhering to these guidelines, even with modifications, is important.

Understanding DOT and EPA Guidelines

While there aren’t specific DOT regulations prohibiting upsizing, the tires you select must carry a DOT compliance code. The EPA is concerned with emissions and fuel economy, which can be affected by changes in rolling resistance and weight.

Maintaining the overall diameter helps keep your vehicle operating within its designed parameters for efficiency and safety systems. This is a matter of responsible modification.

Here’s a quick look at key wheel fitment parameters:

Parameter	Importance for Upsizing
Overall Diameter	Maintains speedometer accuracy and ABS/ESC function.
Bolt Pattern	Ensures wheels physically mount safely to the hub.
Offset	Prevents rubbing and maintains steering geometry.
Center Bore	Guarantees hub-centric fitment, reduces vibration.

Ultimately, switching to 17-inch rims from 16-inch can be a fantastic upgrade for many vehicles. It just requires a methodical approach and attention to detail.

Do your homework, measure twice, and don’t hesitate to seek advice from a trusted automotive professional. Your car will thank you with improved looks and handling.

Can I Put 17 Rims Instead Of 16? — FAQs

Will changing to 17-inch rims affect my speedometer?

Yes, changing rim size can affect your speedometer if the new tire’s overall diameter is significantly different from the original. Your car’s computer calculates speed based on the original tire’s rotations per mile. If the new tire is larger or smaller, your speedometer will read inaccurately, making you go faster or slower than indicated.

Do I need new tires when I switch to 17-inch rims?

Absolutely, you must get new tires. Your existing 16-inch tires will not fit 17-inch rims. When upsizing rims, you need to select new tires with a lower profile (shorter sidewall) to maintain an overall diameter close to your vehicle’s original specification.

What is wheel offset and why does it matter for upsizing?

Wheel offset is the distance from the wheel’s mounting surface to its centerline. It dictates how far the wheel sits inward or outward in the wheel well. An incorrect offset can cause tires to rub against suspension components or fenders, and it can negatively affect steering feel and the longevity of suspension parts.

Can upsizing wheels void my car’s warranty?

Modifying your car’s wheels and tires generally does not automatically void your entire warranty. However, if an issue arises that can be directly attributed to the wheel or tire modification, the manufacturer may deny warranty coverage for that specific issue. It’s wise to check with your dealership or review your warranty document for specifics.

How do I know if 17-inch rims will fit my specific car?

To determine fitment, you need to check your car’s bolt pattern, center bore, and acceptable offset range. You also need to calculate the overall diameter of the desired 17-inch tire and compare it to your original setup. Consulting a reputable wheel and tire specialist or using an online tire size calculator for your specific make and model is highly recommended.
