Deadbolt out of the box is the best still. Start with new wheels and tires. Wheels can be plastic, steel, or brass. I would stick with the steel to start. Just google or injora website steel stamped wheels. Then for tires, my favorite to start with are the Injora Super Swamper Rocks Tyre. And yes it is “Rocks” for some reason. These have one of the best combos of scale and grip for hard surfaces. I would then get some wheel weights. Get the ones with the hex for some others don’t fit the steelie rims. Invest the rest into a better battery charger and another battery. If you have any left over a good injora 1.27mm hex driver to assist with all your future projects.
