D-Shape Flat Bottom Steering Wheel Cover — 15 Inch
A steering wheel cover cut for a flat-bottom, D-shaped wheel — not a round one. If your wheel has a straight section across the bottom, a standard round cover will bunch and sit proud of the rim at exactly the point your hands rest. This one is shaped for it.
Which wheels is it actually for?
14.5 to 15 inch outer diameter, with a flat bottom. That's the sport-wheel shape fitted to:
- Chevrolet Camaro and Corvette
- Ford Mustang
- Honda Civic Type R and Si
- Volkswagen Golf GTI and R
- Most factory sport and performance-package wheels of that diameter
If your wheel is fully round, buy a round cover, not this one. A D-shaped cover on a circular rim leaves slack at the bottom. Measure the outer diameter edge to edge — not across the spokes — and look at the bottom of the rim before you order. Our steering wheel sizing guide walks through both checks.
What it's made of
Perforated leather-texture outer with carbon-fiber-look side panels, over a gel padding layer. The gel is the part you notice on a long drive — it takes the edge off a thin factory rim without making the wheel feel fat. The perforation is there so your palms aren't sitting against a sealed surface in summer.
Reinforced stitching, and a non-slip inner ring so the cover doesn't creep round the rim under load.
Fitting it
Stretch-on, no tools, a few minutes. It's deliberately tight out of the box — that tension is what stops it rotating later. Line the flat section up with the flat section of your wheel first, then work the rest over the rim a section at a time.
Before you order
- Measure outer diameter, edge to edge — you want 14.5 to 15 inches
- Confirm the bottom of your rim is flat, not round
- Between sizes? Size down. A tight cover beds in; a loose one slips
Driving a Class 8 truck? Those run an 18 inch round wheel — see the 18 inch semi truck cover instead.

FAQs
How do I install the Vyonix Beaded Seat Cover?
Follow these easy steps:
- Place the elastic around the top of the seat.
- Insert the discs into the middle of the seat.
- Secure the bottom hooks for a snug fit.
Will the beaded seat cover fit my truck?
Yes! The Vyonix Beaded Seat Cover is designed to fit most semi-truck seats, including popular models like Volvo, Kenworth, Freightliner, and more.
How do I clean the seat cover?
The seat cover is easy to maintain – simply wipe it down with a damp cloth to keep it fresh and clean.
Is the seat cover comfortable for long drives?
They're firm, and that firmness is the point — it's what holds the airflow gap open under your weight. Most drivers notice the beads for a few days and then stop registering them. If what you want is cushioning rather than ventilation, a padded seat cushion is the better product and we'd rather say so.
Is it comfortable for a full shift?
It spreads your weight across many small contact points rather than one flat surface, so the load keeps shifting as you move. We make no medical claims for it — if you have a diagnosed back condition, speak to a clinician rather than relying on a seat accessory.
