18" Wheels vs 17"

i totaly agree with you.... i give them the point that smaller rims do have less rotaional mass but its all wasted with the bigger tires. What iam saying is that smaller rims wont make much of a diffrence you proably wont even be able to feel any increase it so slight. At most it would maybe give you 1000th of second faster.
