[QUOTE=FritoBandito]
BTW... i'm going to NJIT for mechanical engineering... i took honors physics classes in highschool and have aced the physics classes in NJIT...
physics is 1 of my strong points... how bout ya just take my word for it... it can get very complicated to try and explain it...

Here: 17x10.5 bullit DD = 27lbs.
Tire choice is BFG KD: 315/35/17 weight: 32lbs.
For both wheels in rear with tires = 118lbs
Overall Diameter is 25.7"
18x10 bullit = 30lbs
Tire choice BFG KD: 295/35/18: 30lbs.
For both wheels in rear with tires = 120lbs
Overall Diameter: 26.1"
That's hardcore facts. Theres ONLY 2 lbs difference in the rear wheels WITH tires, there goes the argument for weight. The diameter difference is 0.4". With this all in mind, the 17 inch wheel will run about, IDK, about 0.03 secs less than the 18's theoretically.
Basically, if you evenly match the wheels and tires with same products, the size doesnt really matter, its 99% driver.
Also, you could make a slight argument that the 17inch could get better traction since it is 315 width and 18 is 295. BUT can you honestly tell that big of a differance with THESE tires?

The right size 18" tire will be the same diameter as the original 245/45/17 if you get the right sized 18" tire.
On the other hand a 245/45/17 will be shorter than a 255/45/17. So the size of the wheel only has a small part of the equation.
Just get the right size tire and the diameter will not change.
The biggest difference is weight and that is usually due to going to a wider tire. If you go from a 245/45 stock tire to a 315/35/17 you get more weight too. If you go from a 245/45/17 to a 295/30/18 or whatever you will also gain weight on the tire and wheel.

On the other hand, 315 tires are quite a bit heavier than the 245 stocker.

i really dont think that there would be a HUGE difference... but... 17" wheels have less rotating (rotating not linear) weight than 18's...
though that is true... i really dont think that they would slow you down that much... like white thunder said... 18s probably would not add any where near 1/10 a sec... i cant imagine that you would notice anything...

HAVE ANY OF YOU EVER WATCHED DRAGRACING.... FUNNY CAR OR WHATEVR.... EVER NOTICE THAT THEY RUN LIKE 13-15 inch WHEELS??? THEY RUN THEM BECAUSE THERE IS LESS ROTATING WEIGHT!!
