I am building an RC car from scratch. I have two of these motors: 6.3:1 Metal Gearmotor 37Dx50L mm 12V (Helical Pinion), Pololu Item #4747 https://www.pololu.com/product/4747 They have 6mm D shafts.
I bought these wheels because I was originally looking at motors with smaller shafts: Pololu Multi-Hub Wheel w/Inserts for 3mm and 4mm Shafts - 80×10mm, White, 2-Pack
When I realized my mistake I looked for wheels that would work with a 6mm D shaft, but haven’t found anything that looks like it would work, either on pololu.com or elsewhere. Does anyone have any suggestions for wheels that would work with these motors?
