How much does a Hot Wheels Toy Car Weigh?

There is quite a difference between cars with rubber 2-piece wheels (Real Riders wheels) and the normal plastic 1-piece wheels. This is probably because the cars with the 2-piece type are made more for adults and collectors who appreciate both metal bases and rubber tires. On average the Real Riders cars weighed 19.63 grams (0.69 ounces) more than the plastic-wheeled cars.
