Can You Buy Covers for Oversized Steering Wheels? Size Guide
Quick Answer
Yes, you can buy covers for oversized steering wheels, but finding the right fit requires measuring your steering wheel’s exact diameter and grip thickness rather than relying on standard universal sizing.
Understanding Oversized Steering Wheels and Cover Compatibility
Most standard steering wheel covers are manufactured to fit wheels measuring between 14.5 and 15.5 inches in diameter, which accommodates the majority of modern passenger cars, compact SUVs, and sedans. However, larger vehicles such as full-size trucks, older classic cars, heavy-duty utility vehicles, and some RVs often feature steering wheels measuring 16 inches, 17 inches, or even larger.
Attempting to install a standard-sized cover onto an oversized wheel typically results in excessive stretching, damaged stitching, or an incomplete installation where the cover fails to wrap completely around the rim. Specialty manufacturers produce larger covers explicitly designed to stretch across these expanded dimensions safely.
How to Accurately Measure Your Steering Wheel
Before purchasing a cover for a larger steering wheel, taking precise measurements prevents ordering an item that does not fit securely. Guessing the size based on vehicle type alone often leads to loose, slipping covers that can create a safety hazard while driving.
Measuring Wheel Diameter
Place a rigid tape measure or yardstick across the exact center of the steering wheel from one outer edge to the opposite outer edge. Ensure the measurement passes directly through the center hub to capture the true overall diameter.
Measuring Grip Circumference or Thickness
Oversized wheels frequently feature thicker rims than standard passenger vehicles. Wrap a flexible tape measure around the outer grip itself to find its circumference, or use calipers to measure the cross-sectional thickness. Matching both diameter and grip thickness ensures the new cover closes properly without straining the material.
Tip
If your steering wheel measurement falls right on the boundary between two sizes—such as exactly 16 inches—check the manufacturer specifications to see whether the material features high elasticity or requires a snug, tight fit.
Common Size Categories Available on the Market
Shopping for specialty steering wheel covers involves looking beyond standard retail shelves, where large options are rarely stocked. Knowing the industry size designations simplifies the search process.
- Standard Size (14.5″ to 15.5″): Designed for everyday sedans, hatchbacks, and compact crossovers.
- Large Size (15.5″ to 16.5″): Commonly fits mid-size trucks, older SUVs, and larger sedans.
- Extra-Large / Heavy-Duty Size (16.5″ to 18″+): Built specifically for full-size pickup trucks, commercial vans, agricultural equipment, vintage automobiles, and motorhomes.
Material Options for Oversized and Heavy-Duty Steering Wheels
Larger steering wheels are often found in work vehicles, trucks, or older models exposed to heavy daily wear. Selecting the right material impacts both durability and driving comfort.
Genuine and Synthetic Leather
Leather covers offer a premium feel and reliable grip, though genuine leather requires occasional conditioning to prevent cracking under intense sun exposure. Synthetic microfibers provide similar tactile benefits with enhanced moisture resistance.
Rubber and Silicone Core Linings
A high-friction interior lining is essential for oversized wheels. Because larger wheels exert more leverage during turns, a slick interior lining can cause the cover to rotate independently around the wheel, creating a dangerous loss of steering control.
Lace-On Custom Covers
For unique or non-standard wheel dimensions, lace-on leather or synthetic wraps provide the most secure fit. These kits require stitching the cover onto the wheel by hand, allowing the material to pull tightly around thick rims and unconventional diameters without slipping.
Potential Safety Risks of Incorrectly Sized Covers
Installing a cover that is too small or improperly secured introduces significant operational hazards.
Warning
Never force a standard steering wheel cover onto an oversized wheel using excessive heat guns or extreme stretching tools unless explicitly approved by the manufacturer. Over-stretching weakens the core structure, increasing the risk of sudden slippage during emergency maneuvers.
A loose steering wheel cover can rotate freely around the steering wheel rim when applying sudden steering input, preventing the driver from maintaining vehicle control. Always verify that the installed cover remains completely stationary when gripped firmly and twisted.
Installation Tips for Tight Oversized Covers
Oversized covers can be physically demanding to install due to the tension required to keep them secure. Warming the material slightly in the sun or indoors before installation increases flexibility, making it easier to stretch the final section over the rim.
Starting the installation from the top of the steering wheel and working downward evenly on both sides prevents uneven stretching. Ensure the core rubber or plastic backing grips the steering wheel evenly all the way around before driving.

Frequently Asked Questions
How do I know if my steering wheel is considered oversized?
If your steering wheel measures greater than 15.5 inches in outer diameter, it falls into the oversized category. Most standard passenger vehicles use 14.5 to 15-inch wheels, while trucks, older cars, and large SUVs often measure 16 inches or more.
Can I use a standard 15-inch cover on a 16-inch steering wheel?
No, a standard 15-inch cover will typically be too small to stretch safely across a 16-inch wheel. Forcing an undersized cover onto a larger wheel can tear the seams, damage the internal core, or create an insecure fit that slips during driving.
Are lace-on covers better for oversized steering wheels?
Lace-on covers are often recommended for oversized or non-standard steering wheels because they allow you to adjust the tension precisely during installation, accommodating thick grips and unusual diameters securely.
Do truck steering wheel covers differ from car covers?
Yes, truck steering wheel covers are generally larger in diameter and feature thicker cross-sections to match heavy-duty steering rims found in pickup trucks and commercial utility vehicles.
How do I clean a leather oversized steering wheel cover?
Use a mild automotive interior cleaner or a damp microfiber cloth with mild soap to wipe down the surface. Avoid harsh chemical solvents that can dry out leather or synthetic gripping materials.
What should I do if my steering wheel cover slips after installation?
If a cover rotates or shifts during use, remove it immediately. Slippage indicates that the cover is either too large for the wheel or lacks the proper high-friction inner rubber lining required to stay anchored in place.
Conclusion
Finding a suitable cover for an oversized steering wheel simply requires taking accurate measurements of both the wheel diameter and grip thickness rather than relying on standard retail sizing. Choosing a properly rated heavy-duty or large-diameter cover ensures a secure fit, prevents dangerous slippage, and improves driving comfort over long distances. Always verify the correct size specifications before purchasing to maintain safe steering control.
