It makes sense that they would because then you get more movement per rotation of the wheel. But in reality do they
1 cm gain in diameter equals greater distance traveled each minute. The car's speed is limited by available horsepower only and gear ratios. It takes about 195hp to get a 500lb motorcycle to reach 195mph.
per the same about of revolutions. yes. I had a golf cart that I put larger wheels on it it was faster not double or anything extreme. but noticable faster. The offset will be when the wheels are do large that the weight and power to turn them offset the increased diameter.
Size of the wheels doesn't matter. The determining factor is the overall diameter of the wheel and tire package. You could use larger diameter wheels with a low profile tire and end up with a shorter overall tire diameter than a smaller wheel with taller sidewall profile . The shorter tire package will lower the working gear ratio and make the vehicle quicker from point A to point B, but it will cause the engine to wind out sooner and will rsult in a lower top speed. The flaw in your thinkng is that a larger wheel makes for a larger rollout diameter and it isn't always so.
