How do you size a wheel chock?

Measure the height of your tire. A wheel chock is best sized according to the size of the tire and should be approximately 1/4th the height of the tire. If your tire is 36 inches in height, your wheel chock should be around 9 inches high and fit snugly beneath the tire.

What can I use instead of wheel chocks?

Bricks would be safe enough as wheel chocks because the rubber tyre spreads the load. (Imagine trying to chock a railway wagon with a brick however, and it would be another matter.) But all the same, the proper wedge-shaped blocks are probably best.

Do wheel chocks really work?

As we’ve learned, they provide an uphill impediment to your car’s tires, and wheels don’t travel naturally uphill. What’s more, a wheel chock uses friction to keep your car from sliding. So they’re an all-around good investment to keep in your trunk.

How many wheel chocks does OSHA require?

OSHA standard 29 CFR 1910.178 requires vehicle operators to set their truck and trailer brakes and block their wheels to prevent vehicle movement. The standard notes that chocks should be placed under the rear wheels, which means two chocks should be used – chocking just one wheel isn’t enough.

How do I choose a wheel chock?

Ideally, the correct wheel chock should be about 1/4 of the tire’s height. This means that if the vehicle has 36-inch tires, the wheel chock should be about 9 inches in height. This should allow the chock to fit securely under the tire.

How do you buy wheel chocks?

Tire Diameter The size of the tires on your equipment or vehicle will also have an impact on the size and slope of the chock; chocks should be one fourth the diameter of your tire. So, if your truck has 40” diameter tires, the chocks you need will be roughly 10” high.

Weight and incline grade determine how many wheel chocks you need for your RV. Therefore, you should use one chock per tire to make sure it does not roll away. Using four chocks also secures both the front and back end to limit movement. For smaller trailers or fifth wheels, you may be able to get away with two chocks.

Are rubber or plastic wheel chocks better?

Polyurethane plastic is the second most common material for wheel chock. They’re better at resisting cuts, blunt damage, water damage, and wind damage than rubber chocks, and they’re lighter-weight than rubber or aluminum. But, plastic wheel chocks are not as high-strength as aluminum or steel alloy chocks.

Is it necessary to chock the tires of a small trailer?

Wheel chocks are necessary for your RV or travel trailer to keep them from rolling away. Parking brakes work well to keep your rig stable, but they are not reliable on their own. Instead, they are much less likely to fail when used in combination with chocks.
