you need to basicly find the right compromise of weight/rotational enertia/sidewall/outside diameter of the tire
-heavy rims are slower (in most cases)
-bigger rims take more power to spin (even if somewhat lighter)
-you need to have enough sidewall to absorb "issues" with the surface, absorb cornering force, but not too much sidewall though or you will get a spongey ride and a lot of "roll under" when cornering
-the OD of the tire relates directly to your gear ratio (larger OD you will acheive higher top speed but accelerate slower, smaller OD you will accelerate faster but top out at a lower speed)
there really is no set "perfect" choice... it all comes down to what do you want to do with the car
