One minute you're carving around the park. The next, a wheel catches the underside of your deck and the board suddenly slows down. Not ideal. That's skateboard wheelbite — and if it's happening regularly, it's worth sorting before your next session.
Wheelbite isn't just a problem for people running huge cruiser wheels. It can happen on a normal street setup too, especially if you've changed your wheels, loosened your trucks or fitted bushings that compress more than you expected. Here's how to work out what's causing it and what to change.
What is skateboard wheelbite?
Wheelbite happens when a wheel touches the underside of the skateboard deck as the board leans or the trucks compress. That contact creates friction and can slow or stop the wheel unexpectedly. Sometimes you'll see a rubbed patch above the wheel on the underside of the deck.
It isn't the same as catching a wheel on a stone or crack. With wheelbite, the wheel is catching your own board.
Why does wheelbite happen?
There's rarely one universal culprit. It's usually a combination of wheel clearance and how far the board can lean.
- Large wheels: increasing wheel diameter reduces the gap between the top of the wheel and the deck.
- Low trucks: a lower ride height leaves less clearance, although exact truck heights vary by manufacturer.
- Loose trucks: more lean can bring the deck down onto the wheel.
- Soft or worn bushings: bushings that compress easily can allow deeper turns under your weight.
- Your deck and riding style: deck shape, hard landings and deep carving turns can all affect when contact happens.
That's why two skaters using the same wheel diameter can have completely different experiences.
How to check for wheelbite before skating
Put the board on a level surface and look at the underside directly above each wheel. Fresh scuff marks or little worn patches are a clue. Then, with the board stationary, carefully lean it from side to side and watch the gap between the wheels and the deck. Don't put your fingers where they could get pinched.
A hand check can't reproduce every landing or hard turn, so it's not a guarantee. But if a wheel already touches the deck while you're testing it on the ground, don't skate it until you've fixed the clearance problem.
Five ways to stop skateboard wheelbite
1. Make a small truck adjustment
If your trucks are extremely loose, try tightening the kingpin nuts slightly and evenly. Test the steering again after each adjustment. You still want a board that turns comfortably; cranking the nuts down until the bushings are crushed isn't a good fix.
Our guide to skateboard truck tightness explains how to find a workable balance.
2. Consider riser pads
Riser pads sit between the deck and truck baseplates, raising the deck away from the wheels. They're a common option if you want to keep larger wheels or a looser turning feel.
Typical flat riser thicknesses include 1/8 inch (about 3mm) and 1/4 inch (about 6mm). Neither is a magic number: the clearance you need depends on your wheel size, truck geometry, bushings and how far you lean.
Important: adding risers usually means you'll need longer mounting bolts. Check that the bolts are long enough to secure the truck hardware properly. If you're unsure, ask a skate shop to check the setup before riding.
3. Check your bushings
Bushings are the urethane cushions inside your trucks. If they're too soft for your weight or badly worn, the board may lean further than you want. A firmer, correctly sized bushing can help, but don't buy the hardest ones available without thinking about how you want your board to turn.
Start with our soft vs hard skateboard bushings guide if you think they're part of the problem.
4. Try smaller wheels
Reducing wheel diameter creates more room between the wheel and deck. If you've recently swapped from a small street wheel to a bigger cruising wheel and started getting wheelbite, that change is a likely clue.
As a rough guide, many standard street setups with 49–54mm wheels don't need risers, while larger wheels may need more clearance. But it's not a guarantee: loose trucks and deep turns can still cause bite with smaller wheels. See our 52mm vs 54mm wheel guide for the difference between common street sizes.
5. Match truck height to the setup
If you're building a board from scratch, look at truck height and wheel diameter together. A taller truck can give you more clearance without adding a separate riser, although it also changes how high the board sits. The words low, mid and high aren't perfectly standard across brands, so compare actual manufacturer dimensions.

Do I need risers for 54mm, 56mm or 58mm wheels?
| Wheel diameter | Useful starting point |
|---|---|
| 49–54mm | Often works without risers on a typical street setup, but check for contact. |
| 55–57mm | Consider around 1/8-inch risers, particularly with lower or looser trucks. |
| 58–64mm | More clearance is often needed; 1/8- to 1/4-inch risers are common starting points. |
These are general setup guidelines, not guarantees. Your trucks, deck and riding style decide whether a particular combination is safe from wheelbite. Always check the assembled board.
Should you use wax to stop wheelbite?
You might see skaters putting wax on the underside of a deck where the wheels rub. It may reduce friction in some situations, but it doesn't create clearance and shouldn't be treated as a reliable fix for a wheel that catches hard enough to stop. Fix the setup rather than relying on wax to hide the problem.
What about rough UK streets?
It's tempting to fit bigger, softer wheels when the local pavement feels like a cheese grater. Fair enough — they can make rough ground more comfortable. But changing wheel size can create a clearance issue you didn't have before. If you're switching from park wheels to a more cruising-friendly setup, check for wheelbite before heading out.

Quick FAQs
Can wheelbite make you fall?
Yes. If a wheel suddenly catches the deck, it can slow abruptly and throw you off balance. Don't ignore repeated wheelbite.
Will tightening my trucks always fix it?
No. It can reduce lean, but won't solve every mismatch between wheel size, truck height and deck clearance.
Are risers only for cruisers?
No. Street and park skaters can use them too if their setup needs more clearance.
Do I need longer bolts with risers?
Usually, yes. Choose mounting hardware long enough for the deck, riser and truck baseplate, with the nuts properly secured.
The FK takeaway
Wheelbite is a setup problem, not something you have to put up with. Start by checking where the wheel touches, then work through truck adjustment, bushings, wheel size and risers. Change one thing at a time so you know what's actually helped.
