Wheel weight-Significant?
#23
I don't think 9lbs is correct - the only way I can figure he got that number was the tire fitment thread says they weigh 37 lbs "a set" which I think is referring to a tire AND wheel as a set, not a set of tires ands wheels. They definitely weigh more than 9 lbs - I carried them to the shed...

i have 19s which wiegh 18 pounds and i think the size of the wheel makes more of a difference with acceleration than with weight from personal experiance. ive had 18s that weighed more but felt a little less sluggish smaller wheels have a smaller diameter and it takes less power to spin them . . or maybe im wrong

Diameter is a totally different thing and should probably have a topic of its own.
For diameter, the important measurement is the TIRE, not the rim itself. Its one reason low-profile tires are used with large rims, to keep the diameter down.
A small overall diameter will make the car accelerate quicker *IF* it still has enough grip to get good traction. It will also cause the car to have a lower top speed, and it will make overall traction WORSE so you don't want to overdo it on getting smaller tires.
On the other hand, if you are making serious power, you will need a taller tire anyway just to get decent traction. But that hurts acceleration, and increases top speed.
Its why a good reading of 60 foot times is important in dialing-in the car for quarter-mile drags...
