Power Wheels Upgrade - Pneumatic Tires

Upgrading the Power Wheels Jeep with pneumatic tires. Tires get pricey, so I opted to get 13" tires from Harbor Freight Tools and had to make some adjustments. In addition to drilling holes to secure the rear drivers to the hub, I used PEX tubing to keep the axle snug, and decided to drill holes for cotter pins. So far...so good!
