How to Choose a 13 Inch Steering Wheel Cover: Fit, Types & Installation

If you're searching for a 13 inch steering wheel cover, it's likely because you want to improve grip, reduce hand fatigue, or protect your original steering wheel from wear. While many modern vehicles come with larger diameter wheels (typically 14–15 inches), 13-inch models are still found in classic cars, compact vehicles, motorsport applications, and some sim racing setups. Finding the correct cover requires understanding exact dimensions, material options, compatibility with airbag systems, and installation methods. This guide breaks down everything you need to know about selecting, fitting, and maintaining a 13 inch steering wheel cover that matches your driving needs—whether daily commuting, restoration projects, or track use.

Why Use a 13 Inch Steering Wheel Cover?

Steering wheel covers serve multiple practical purposes beyond aesthetics. For owners of older European compacts, vintage sports cars like the MGB, or custom-built race vehicles, a 13 inch steering wheel is not uncommon 1. Over time, leather can crack, plastic hardens, and foam padding compresses, leading to reduced control and discomfort. A well-fitted cover restores tactile feedback and enhances safety by improving grip, especially in wet or cold conditions.

🔧 Key benefits include:

• Enhanced grip: Textured surfaces like silicone, rubberized stitching, or perforated leather increase friction between hands and wheel
• UV and wear protection: Shields original materials from sun damage and abrasion
• Comfort improvement: Adds cushioning for long drives or high-vibration environments
• Cosmetic refresh: Hides stains, scratches, or aging without costly replacement
• Temperature regulation: Some materials resist heat buildup in summer and remain flexible in winter

Understanding 13-Inch Wheel Sizing: Diameter vs. Circumference

📍 One common point of confusion involves how steering wheel size is measured. The term "13 inch" refers to the diameter—the straight-line distance across the center of the wheel from one outer edge to the opposite. However, when shopping for covers, some retailers list circumference instead, which can lead to incorrect sizing.

To verify your wheel’s actual size:

1. Use a flexible tape measure around the outer rim (circumference)
2. Divide that number by π (~3.14) to get diameter
3. For a true 13-inch diameter wheel: 13 × 3.14 ≈ 40.8 inches (103.6 cm) circumference

📏 Example: If your measurement shows 39–41 inches in circumference, a 13-inch cover should fit. Smaller than 38" may require a 12-inch model; above 42" suggests a 14-inch wheel.

⚙️ Note: Not all 13-inch wheels have the same depth or spoke configuration. Deep-dish designs, thick rims, or offset spokes may interfere with standard elasticized covers. Always check product specs for maximum rim thickness and clearance requirements.

Material Comparison: What Works Best for 13" Wheels?

The choice of material affects comfort, longevity, and safety. Below is a breakdown of commonly used options:

Material	Grip Level	Durability	Heat Resistance	Airbag Safety
Synthetic Leather (PU)	Moderate	2–3 years	Good	Limited – avoid thick layers
Real Leather	High	5+ years	Excellent	Yes – if thin and breathable
Neoprene/Fabric	Low-Moderate	1–2 years	Fair	Generally safe
Silicone/Rubber	Very High	3–5 years	Good	No – blocks sensor activation
Alcantara®	Very High	4+ years	Excellent	Conditional – consult manufacturer

✨ Tip: Avoid full silicone or rubber covers on airbag-equipped vehicles. These materials can inhibit the rapid inflation needed during deployment and may pose a safety risk.

Compatibility Concerns: Airbags, Horn Pads & Electronics

❗ Installing a steering wheel cover incorrectly—or choosing the wrong type—can compromise critical safety systems. Modern OEM wheels integrate horn contacts, cruise control buttons, and airbag sensors into the rim and hub.

Before purchasing:

• Check whether your vehicle has a driver-side airbag. If yes, avoid thick, rigid, or fully encapsulating covers.
• Look for products labeled “airbag compatible” or “thin-profile.”
• Ensure horn pad remains accessible and pressure-sensitive areas aren’t obstructed.
• Never glue or permanently bond a cover over an airbag zone.

🔍 According to NHTSA guidelines, any aftermarket addition must not delay or prevent airbag deployment 2. While there’s no federal ban on covers, liability could fall on the owner in case of injury due to interference.

Installation Tips for a Secure Fit

⏱️ Proper installation ensures both performance and safety. Follow these steps when applying a 13 inch steering wheel cover:

1. Clean the surface: Use isopropyl alcohol to remove oils, dust, and residues from the existing wheel.
2. Align starting point: Begin at the bottom center (6 o’clock position) where visibility is lowest.
3. Stretch evenly: Work clockwise and counterclockwise simultaneously to avoid wrinkles.
4. Secure seams: Tuck excess material into grooves or use included clips.
5. Test functionality: Press horn, turn wheel lock-to-lock, ensure no slipping occurs.

🧼 Maintenance: Clean every 4–6 weeks with mild soap and water. Avoid petroleum-based cleaners that degrade synthetic materials.

Where to Buy 13 Inch Steering Wheel Covers

🌐 While global marketplaces like Alibaba offer bulk options for 13 inch steering wheels and related accessories 3, finding exact-fit covers requires careful filtering. Many listings describe generic “universal” sizes that claim to fit 13–15 inch wheels—but elasticity varies widely.

When sourcing online:

• Verify seller ratings and customer photos
• Look for dimension charts (not just “fits most” claims)
• Prefer suppliers who specify inner diameter range
• Contact support before ordering if your wheel has unusual contours

🏭 Specialty shops catering to classic British cars, mini racers, or sim rig builders often carry niche-sized components. Forums such as r/simracing discuss adapting 13-inch wheels for Logitech G920 setups, where smaller diameters offer higher torque resistance and finer control 4.

Common Misconceptions About Small-Diameter Wheels

❓ Some drivers assume smaller wheels (like 13") make steering easier. In reality, mechanical advantage decreases with diameter—meaning more effort is required to turn the front wheels, especially without power assist.

📉 Trade-offs include:

• Increased steering effort: Especially noticeable at low speeds or when parking
• Faster rotation speed: More turns lock-to-lock, requiring quicker hand movements
• Limited hand placement options: Less space for palm positioning during extended drives

⚡ Conversely, in racing contexts, a 13-inch wheel allows faster directional changes and better cockpit clearance—advantages valued in tight oval tracks or cramped chassis layouts.

Alternatives to Covers: When Replacement Makes Sense

📋 In some cases, replacing the entire steering wheel is safer and more effective than adding a cover. Consider this option if:

• The underlying wheel is cracked, loose, or structurally compromised
• You’re upgrading to a quick-release system for track use
• Your car lacks airbags and you want a period-correct or sportier look
• You need precise compatibility with shift lights, data displays, or custom hubs

🔄 Aftermarket 13-inch wheels made from aluminum, wood-rim, or suede-wrapped composites are available through motorsport suppliers. Ensure any replacement maintains proper clock spring alignment and wiring continuity for essential functions.

Final Checklist Before Buying a 13" Cover

📎 Use this decision framework before making a purchase:

• ✅ Measured actual diameter and confirmed it’s truly 13 inches
• ✅ Verified presence (or absence) of airbag system
• ✅ Assessed material suitability for climate and usage frequency
• ✅ Reviewed return policy in case of poor fit
• ✅ Checked for interference with mounted controls (cruise, audio, etc.)
• ✅ Confirmed ease of cleaning and maintenance access

🎯 Bottom line: A 13 inch steering wheel cover can be a smart upgrade—if chosen carefully. Prioritize safety, fitment accuracy, and functional needs over appearance alone.
