See my post #15 in this thread and post #16 on the thread I reference there for first order approximations on rotational inertia comparison.

These are fine educated statements made by persons who obviously have a lot of knowledge in this area. Nevertheless, the real world data collected by Car and Driver indicated that, comparing identical brand wheels and tires (19 vs 18), the 18 inch versions had better acceleration, better roadholding, better ride, better fuel mileage, lower total (wheel + tire) weight, and lower total cost.

I believe this is the magazine comparison you are referring to? http://www.caranddriver.com/features...sted-tech_dept Let's look at the details: 1. They are comparing 18"x8.0" rims with 19"x8.5" which have 225/40/18 and 235/35/19 tires on them. So this is an apples to oranges comparison. The 19" rim and tires are wider, which is most likely where the 3 lb weight difference in the total weight is coming from. 2. I already referenced some specific 18" vs 19" setup that weigh pretty much the same at the same rim model, tire model, rim width, tire width, and rolling diameter. (I am not claiming that is the case for all rim brands as in some case manufacturers increase the loading specs on the 19" rims as they are more likely to be used on a heavier car). 3. Despite the apples to oranges comparison, the C&D data show no difference in acceleration figures between the 18" and 19" setups they test. 0-60 in 7.9s, and 1/4 mile 16.1s @ 86 mph for both setups. The only minor difference is in the 0-100mph, which is 23.3s vs 23.4s. That's just noise. #3 above supports what I've been saying all along (despite the apples to oranges comparison). I never made any claims about ride quality, handling or cost.

But I guess If I get rid off the Run Flats I might save some weight on the tire no? I assume that Run Flats are heavier just becasue the type of tire... |

Stay away from those and stay with Hankook tires that you had chosen. Your ride will feel much more planted and compliant. |

The car is in the shop right now getting fixed because some stupid drunk chic did hit my car on the front fender.... Long story short, the car will be ready this coming week and I did ask the body shop to make it look like Show room again. Then the wheels will get installed next week too .... Honestly I can't wait... In the mean time I'm driving the 135i and the same set of rims (18" though) will on on it this Monday.... I can't waaaait!!!

Piano Black was the perfect color! The car looks amazing. Quick question? Is it lowered or is it on OEM springs? I can't tell from the picture. |

Hey Eddy, I love the combination man.... My son calls it the Bat-mobile LOL. Right now I have the OEM suspension but I will be lowering it soon. I think I'll be getting KW, what do you think?
I'll take more pictures tonight and post them
