AOWESM Wiggle Car Polyurethane Replacement Wheels Upgrade Swing Car Wheels w/Bearings ABEC-9 for Ride-on Toys - Twist, Swivel, Go - 2 Convex Front Wheels, 2 Concave Rear Wheels (Blue)

Works really well with the scooter we bought for my child.

These wheels are so smooth - makes our grandson’s plasma car glide smoothly inside and out. He loves how the car moves with ease. At 2 years old, it’s one of his favorite toys.

We bought a cheaper wiggle car but it had crappy plastic wheels and the kids didn't want to ride it. It was super easy to swap out the noisy hard plastic wheels with these. They're faster and quieter, probably ride smoother too. Totally worth it.

For those who have ever gotten their child a plasma car and who quickly discovered that this indoor-only product is incredibly noisy on hardwood, tile and concrete floors, these wheels are for you. They are WHISPER QUIET (sorry I shouted - but it's wondrous). And, they stop the plasma car from skidding on tight turns. My son can zip around our family room and hallway and my wife and I can converse now at a normal volume. I cannot emphasize how quiet this has made the plasma car. And because these wheels are essentially roller blade wheels, my son can now ride his plasma car OUTSIDE! He loves it.For those concerned about installing these on the plasma car, it took me all of 5 minutes and it only took that long because it took me 3 minutes to find my small wrench to unscrew the nuts on the front wheels. These couldn't have been easier to install.You may be put off by spending another almost $30 after spending $75+ on a plasma car, but these wheels are worth it. They have excellent, smooth bearings, feel extremely solid and fit the plasma car perfectly.

Love that these don’t scratch up my hard wood! Very easy to assemble. Very happy with this purchase.

The wheels that came with our plasma cars, that we had for about 5 years, were completely demolished. These were an easy swap out, and now the cars are like new! My kids are thrilled! Plus they ride much smoother, and go faster!

These wheels fit perfectly and made an amazing difference in noise, smoothness of ride, better maneuverability. balance, speed and balance. You just have to be careful to notice the difference between the from and back wheels. It has nothing to do with convex or conclave but rather the thickness or thinness of the depth of the hole in the center of the wheel. We figured it out by measuring that depth. Its such a small difference that it is not recognizable just by looking at them.

Nice wheels, but did not workFor what we needed. We had to return them.
