Rubber Tire Upgrade Kit for Power Wheel Kids Electric Ride On Car, Anti-Slip and Noise Reduction Wheel Replacement, Durable Shock Absorbing Tire Protection Covers for Plastic Wheels-2PCS

What you can do, I realize they are worn pretty bad, but you can take a cheap bike tire, and cut it to lay flat and screw it to the “tires” This is also an option on Amazon, https://a.co/d/08bwzzt8 Eta, a marketplace search for a parts toy might also work. I agree, tires for these things are stupid pricey across all the brands I think

You can also get these, basically the same thing. I was thinking about it after we first did the battery upgrade, but my son ended up liking doing burnouts and being able to drift it lol
