So you’ve thought ahead and bought a spare tire for your trailer—good so far. But if you think you can just use your car jack to do the heavy lifting, think again. Most car jacks won’t raise the trailer high enough, and hydraulic jacks are heavy and take up a lot of space. That’s why these special lightweight jacks really come in handy.
The wedge-shaped aluminum EZ Jack (about $80 from cabelas.com) is perfect for trailers with tandem wheels. First, loosen the lug nuts on the flat tire first. Then wedge the EZ Jack under the good front tire and pull the entire trailer forward (or place it on the back wheel and drive backward if it’s a flat front tire). Then chock the opposite side. Swap out the tires, then toss the lightweight jack (9 lbs.) back in your truck and you’re good to go.
The Easy Lift Jack (available through our affiliation with amazon.com about $32) is perfect for boat and utility trailers (up to 2 tons). First, loosen the lug nuts on the flat tire. Then match up the cutout portion on the jack to the trailer axle. Wedge the teeth along the circular edge into the road and pull the trailer forward. Expect some skidding until it bites into the road surface. Once it’s raised, block the other wheel with a wheel chock and swap the tires.
