Why is Your C8 Corvette Tire Making Noise?

How to Fix Tire Noise on Your C8

Experiencing unusual tire noise or temperature fluctuations can be concerning. As one owner reported: "I still have a feeling it's the tires / rims. I remember when putting the wheels on, looking at the hole in the wheels and the hub diameter they were not perfectly centered, but very close." (source). This guide helps 2020 Chevrolet Corvette owners address these tire-related issues, focusing on potential causes and solutions based on real-world experiences.

Symptoms

Unusual tire noise is a primary symptom reported by owners. This noise can manifest in various ways, such as a humming, roaring, or even a rhythmic thumping that increases with speed. Identifying the type of noise can provide clues to its origin. For example, a constant humming might suggest a worn tire, while a thumping could indicate a bulge or foreign object embedded in the tire. Pay close attention to when the noise occurs – is it present at all speeds, or does it only appear above a certain velocity? Is it more noticeable during turns or when driving straight? These details can help narrow down the possible causes.

Another reported symptom is fluctuating tire temperatures. While some variation in temperature is normal during driving, significant or uneven temperature differences between tires can signal underlying problems. For instance, a tire that consistently runs hotter than the others may be experiencing excessive friction due to brake drag, misalignment, or even low inflation. Monitoring tire temperatures can be done with an infrared thermometer or through the Corvette's built-in performance data recorder if equipped with that option.

It's also important to consider the overall condition of the tires. Visually inspect the tires for signs of uneven wear, bulges, cuts, or embedded objects. Uneven wear patterns, such as excessive wear on the inside or outside edges, can indicate alignment issues or improper inflation. Bulges or cuts in the sidewall are serious safety hazards and require immediate attention. A tire pressure monitoring system (TPMS) warning light can also indicate problems, such as low tire pressure or a malfunctioning sensor.

Don't dismiss unusual vibrations. Although subtle, vibration can be associated with tire issues. Carefully asses to see if vibrations are speed-dependent. If the vehicle vibrates at certain speeds but not at others, it may be due to unbalanced tires.

Most Likely Cause

The most likely cause of tire noise is the wheel alignment. While a direct intake leak isn’t immediately tied to tire noise, it can impact engine performance, potentially leading to driving habits that exacerbate tire wear. The other possible cause based on owner discussions is wheel centering. As one owner stated, there was a chance "that the wheel is not aligned correctly on the hub?" (source.

How to Diagnose

Begin by visually inspecting the tires for any obvious signs of damage or wear. Check the tire pressure using a reliable tire pressure gauge. Ensure that all tires are inflated to the recommended pressure specified on the driver's side doorjamb. Use an infrared thermometer to check the tire temperatures of each tire after driving. A significant temperature difference between tires can indicate brake drag or other issues.

Next, carefully inspect the wheel for any obvious misalignment. Are there any noticeable gaps, or uneven placement on the hub? Take the vehicle for a test drive. Pay close attention to the tire noise and any vibrations that may be present. Note the speed at which the noise or vibrations occur, and whether they change during turns or braking. Finally, consider a professional wheel alignment check. A qualified technician can use specialized equipment to measure the alignment angles (camber, caster, toe) and identify any deviations from the factory specifications.

Step-by-Step Fix

While a direct "fix" for an intake leak impacting tire noise isn’t available, addressing underlying alignment or tire-related issues is the key. One can inspect the tire and rim setup, and then consider the options for addressing the issue.

1. Inspect the tires: Check for wear, damage, and proper inflation. Ensure all tires are inflated to the recommended pressure.
2. Inspect the rims: Look for physical defects, damage or imbalance.
3. Check for correct wheel installation: As one owner suggested, ensure "Did you make sure to use hub-centric wheels, or adapters to make them hub centric?" (source.
4. Balance the tires: Have the tires professionally balanced.
5. Get an alignment: Get the wheel alignment professionally checked and adjusted.

Parts and Tools Needed

• Tire pressure gauge
• Infrared thermometer (optional)
• Jack and jack stands
• Wheel chocks
• Torque wrench
• Hub-centric rings (if needed)
• Offset uppers (mentioned by owners, specific part number not available)
• New Tires (If there is excessive tire wear)
• Wheel (if the current wheel is defective or broken)

Real Owner Costs

Tire balancing typically costs around $15-$30 per tire at a local tire shop. A four-wheel alignment can range from $75 to $200, depending on the shop and the complexity of the adjustment. Replacement tires can vary widely in price, depending on the brand, size, and type of tire. High-performance tires for the 2020 Chevrolet Corvette can range from $300 to $600 per tire. If hub-centric rings are needed, they typically cost around $20-$50 for a set of four.

Doing the job yourself can save on labor costs, but requires specialized tools and knowledge. The alignment needs specialized equipment that is not typically available to home mechanics. Balancing can be done, but is similarly difficult. One owner was able to get a good deal. As shared by one owner, they "Sold the stock intake for $100, front and rear sway bars for $120 and grabbed these little guys for $100." (source.

Prevention

• Regularly check and maintain proper tire pressure.
• Rotate your tires every 5,000-7,000 miles to promote even wear.
• Have your wheel alignment checked and adjusted as needed, especially after hitting potholes or curbs.
• Inspect your tires regularly for signs of wear, damage, or embedded objects.
• Address any unusual tire noise or vibrations promptly.
• Use ramps to protect the wheel (mentioned by owners) when lifting your vehicle.

What Owners Say

Real experiences from CHEVROLET owners:

Success Stories

"OK, for the last few days I have been trying to get the glass into the doors and struggling all the way. I posted before that the passenger side vent window dropped right in and worked with no issues." — mccarley (source)

Owner Experiences

"I am actually a little shaky just writing this. If you have been following the other thread where I was trying to get to the bottom of a body alignment / assembly issue, you will be glad to know that I am confident that it has been solved." — mccarley (source)

"So way back when I thought that I was going to start assembling the body I was trying to level the car on my lift. I had bought a lift, rebuilt it, and installed and leveled it." — mccarley (source)

"I had bought a lift, rebuilt it, and installed and leveled it. I rolled the chassis on it and was trying to level the frame to the lift by adjusting the suspension." — mccarley (source)

FAQ

Q: How long does it take to fix tire noise?

A: The time required depends on the cause. Balancing tires might take 30-60 minutes, while a wheel alignment could take 1-2 hours. Replacing tires could take 1-2 hours, depending on the location. More complicated issues, such as intake leaks, could take longer to diagnose and repair, depending on the severity of the leak and the mechanic's workload.

Q: Can I drive with tire noise?

A: It depends on the severity and the underlying cause. If the noise is minor and doesn't affect handling, it may be safe to drive for a short period. However, if the noise is accompanied by vibrations, uneven wear, or other symptoms, it's best to have the vehicle inspected by a professional as soon as possible. Ignoring these symptoms could lead to more serious problems, such as a tire blowout or suspension damage.

Q: Is this a common issue on the 2020 Chevrolet Corvette?

A: Tire noise and wear are common issues on many vehicles, including the 2020 Chevrolet Corvette, especially those driven aggressively or on rough roads. Factors such as tire quality, driving habits, and road conditions can all contribute to tire wear and noise.

Q: DIY vs mechanic - what's recommended?

A: Simple tasks like checking tire pressure and inspecting tires can be done DIY. If the issue goes beyond this, it is important to involve a mechanic. As one owner stated "You are not whining, but I'm not sure how to address your concern, given there is NOTHING that can be guaranteed 100% problem free." (source.
