The stock tires even weighted just weren’t cutting it. Bought some RC4WD chrome steel wheels and RC4WD Wrangler Radial M/T tires. The tire and wheel combo added about 6g of weight over the stock wheels, tires and weights. The new tire and wheel combo made a big difference in the way the Deadbolt crawled on my indoor track.
The wheels are 3 piece, well if you count the inter ring then it’s 4 pieces. Holding the hex adapter and the 2 wheel halves and lining up all the holes and compressing to get the screws started was a PIA. Decided to 3D print a piece that would fit in the wheel holding it off the workbench and also hold the hex adapter. This with a little pick made it much easier to get the holes lined up.
