Can You Fit Inner Tubes to Corroded Alloy Wheels?
If you own a 2012 vehicle (or any car with older alloy wheels), you may have encountered corrosion issues. When alloys corrode, the surface can become rough and prevent tyres from sealing properly. One of the first questions people often ask is whether they can simply fit an inner tube. Let’s explore this in more detail, along with refurbishment options and potential care products.
Why Alloy Wheels Corrode
Protective Coating Breakdown
Alloy wheels are coated to protect against everyday wear. Over time, road salt, brake dust, and debris can chip away at this protective layer.
Environmental Factors
In wet climates, moisture can penetrate tiny scratches in the coating and accelerate corrosion.
Ageing Wheels
Even with regular cleaning, older wheels are bound to show signs of wear and tear.
The Problem with Tyre Sealing
When alloy wheels corrode, the sealing surface between the tyre bead and the wheel rim is compromised. Common issues include:
- Slow leaks: Air escaping at the rim, leading to frequent re-inflation.
- Difficult tyre mounting: Technicians may struggle to achieve a secure seal.
- Safety risks: Poorly sealed tyres can lose pressure quickly, affecting handling and braking.
Fitting Inner Tubes: Is It Advisable?
Although it might seem like a quick fix, adding inner tubes to tubeless wheels is generally not recommended. Here’s why:
Rim Shape
Modern alloy wheels often have interior ridges and contours designed for tubeless tyres. These may cause wear points against an inner tube, potentially leading to sudden blowouts.
Heat Buildup
Inner tubes can create additional friction and heat, especially at motorway speeds, which may accelerate wear or cause failure.
Tyre Compatibility
Tyres made for tubeless systems might not be designed to accommodate tubes. An improper fit can cause uneven wear or bulging.
Refurbishment: A More Reliable Solution
Rather than fitting inner tubes, consider a professional refurbishment to restore your wheels. Several methods exist, each varying in cost, durability, and finish.
Powder Coating
Process: The wheel is stripped, sandblasted, and coated with a specialised powder before being baked at high temperature.
Benefits: Offers a durable and protective finish; resistant to chips and scratches.
Considerations: Slightly higher cost due to the additional steps, but often the most long-lasting option.
Diamond Cutting
Process: A lathe is used to precisely remove a thin layer of alloy and create a shiny, metallic finish.
Benefits: Popular for premium vehicles; provides a distinctive, polished look.
Considerations: This finish is more prone to corrosion if damaged. Repairs can be slightly more expensive.
Painting
Process: The wheels are stripped, primed, and painted, similar to how a car body is painted.
Benefits: A wide range of custom colours and finishes; often more affordable.
Considerations: Less durable than powder coating but easier (and cheaper) to touch up.
Cost and Time Considerations
Cost Range: Refurbishment can vary from around £50 per wheel for basic painting to over £100 per wheel for advanced powder coating or diamond cutting.
Turnaround Time: Typically one to three days, depending on the extent of the damage and the methods used.
Additional Solutions and Products
Temporary Rim Sealants
Examples: Some garages use bead sealants like Rema Tip Top or Wurth rim seal paste.
Usage: Applied directly to the rim to aid in sealing.
Longevity: Often a short-term fix—repeated applications may be needed.
Wheel Care Products
- Protective Coatings: Ceramic or polymer-based coatings (e.g., Gtechniq or Autoglym wheel sealants) can help maintain the wheel’s finish.
- Cleaner Sprays: Products designed to remove brake dust and salt can slow corrosion.
New Alloy Wheels
- Best for Severe Damage: If the alloy structure is compromised, replacements might be more cost-effective.
- Style Upgrades: New wheels can enhance aesthetics and may improve resale value.
Professional Advice
Safety First: Always consult with a trusted garage or wheel specialist. If corrosion is severe, replacing rather than refurbishing may be the safest option.
Conclusion
Fitting inner tubes to corroded alloy wheels is usually not the best solution, due to design and safety considerations. Investing in a thorough refurbishment or, in extreme cases, replacing your wheels will not only restore the seal but also ensure the safety of your vehicle. If you’re struggling with minor leaks, consider short-term sealants or cleaning products, but keep in mind these are typically temporary solutions.
Ultimately, the best approach is to seek professional guidance. A reputable wheel specialist can evaluate your alloys and recommend whether refurbishment, replacement, or a combination of both is right for your situation. In the long run, properly maintained and refurbished wheels are worth the investment, helping you avoid repeated tyre leaks and maintain a safer driving experience.
Key Takeaway:
Inner tubes are generally unsuitable for modern alloy wheels. Proper refurbishment or replacement is a safer and more effective way to restore functionality and protect your tyres.
